Introduction date 1971-01-01
By the Decree of the Committee of Standards, Measures and Measuring Instruments under the Council of Ministers of the USSR of February 7, 1969 N 168, the introduction date was set from 01.01.71
Reissue. March 2004
1. This standard applies to identification coloring, warning signs and marking plates of pipelines (including connecting parts, fittings, fittings and insulation) at designed, newly built, reconstructed and existing industrial enterprises inside buildings, at outdoor installations and communications located on overpasses and in underground channels in order to quickly determine the contents of pipelines and facilitate the management of production processes, as well as ensuring labor safety.
The standard does not apply to the identification coloring of pipelines and ducts with electrical wiring.
2. The following ten enlarged groups of substances transported through pipelines are established:
1) water;
3) air;
4) combustible gases (including liquefied gases);
5) non-flammable gases (including liquefied gases);
6) acids;
7) alkalis;
8) combustible liquids;
9) non-flammable liquids;
0) other substances.
3. Identification coloring and digital designation of enlarged groups of pipelines must correspond to those indicated in Table 1.

4. Characteristics of colors of identification coloring should correspond to those specified in Appendix 1.
5. Fire-fighting pipelines, regardless of their content (water, foam, steam for extinguishing a fire, etc.), sprinkler and deluge systems in the areas of shut-off and control valves and at the points of connection of hoses and other fire extinguishing devices must be painted red (signal).
If it is necessary to indicate the contents of fire-fighting pipelines, it is allowed to additionally designate them by means of marking plates painted in the appropriate distinctive colors.
6. Identification painting of pipelines should be carried out continuously over the entire surface of communications or in separate sections.
The method for performing identification painting should be selected depending on the location of the pipelines, their length, diameter, the number of lines located together, safety and industrial sanitation requirements, lighting conditions and visibility of pipelines for maintenance personnel and the general architectural solution.
It is recommended to paint pipelines in sections in workshops with a large number and length of communications, as well as in cases where, due to the increased requirements for color rendering and the nature of the architectural solution of the interior, a concentration of bright colors is undesirable due to working conditions.
Identification painting over the entire surface of pipelines is recommended for use with a small length and a relatively small number of communications, if it does not worsen working conditions in the shops.
On outdoor installations, it is recommended to use identification coloring over the entire surface only in cases where this does not cause deterioration of operating conditions due to the effect of solar radiation on communications.
7. When applying identification coloring in sections to pipelines located inside industrial premises, it is recommended to paint the rest of the communications surface in the color of walls, partitions, ceilings and other interior elements against which the pipelines are located. At the same time, it is not allowed to paint pipelines between sections with an identification color adopted to designate other enlarged groups of substances.
8. When applying identification coloring in sections to pipelines located outside buildings, it is recommended to paint the rest of the communications surface in colors that help reduce the thermal effect of solar radiation on pipelines.
9. When laying communications in impassable channels and when laying communications without channels, areas of identification coloring on pipelines should be applied within the chambers and manholes.
10. Areas of identification coloring should be applied, taking into account local conditions, at the most critical communication points (at branches, at joints, flanges, at points of selection and instrumentation, at places where pipelines pass through walls, partitions, ceilings, at inputs and outputs from industrial buildings, etc.) at least 10 m inside production facilities and outdoor installations and 30-60 m on external main routes.
11. The width of the areas of identification coloring should be taken depending on the outer diameter of the pipelines (including insulation):
for pipes with a diameter of up to 300 mm - at least four diameters;
for pipes with a diameter of more than 300 mm - at least two diameters.
With a larger number of parallel communications, it is recommended that the areas of identification coloration on all pipelines be of the same width and applied at the same intervals.
With large diameters of pipelines, areas of identification coloring may be applied in the form of strips with a height of at least 1/4 of the pipeline circumference.
The width of the strips must correspond to the dimensions established for pipelines of a given diameter.
12. To designate the most hazardous substances transported by properties, warning color rings should be applied to pipelines.
Identification colors for warning rings must correspond to those indicated in Table 2.
table 2
Signal color samples | Name of signal colors | Properties of the transported substance |
| Flammable, flammable and explosive |
|
| Danger or harmfulness (poison, toxicity, ability to cause asphyxiation, thermal or chemical burns, radioactivity, high pressure or deep vacuum, etc.) |
|
| Security or Neutrality |
Notes:
1. When applying yellow rings for identification coloring of pipelines of gases and acids, the rings must have black borders with a width of at least 10 mm.
2. When applying green rings for the identification color of water pipelines, the rings must have white borders with a width of at least 10 mm.
13. In cases where a substance simultaneously has several dangerous properties, indicated by different colors, rings of several colors should be applied to pipelines at the same time.
On vacuum pipelines, in addition to the distinctive color, it is necessary to give the inscription "vacuum".
14. According to the degree of danger to human life and health or the operation of the enterprise, substances transported through pipelines should be divided into three groups, indicated by the corresponding number of warning rings in accordance with Table 3.

INTERSTATE STANDARD
PIPELINES OF INDUSTRIAL ENTERPRISES
Identification painting, warning signs and labels
Pipe lines of industrial plants. Identification colouring, safety signs and marking screens
ISS 23.040
Introduction date 1971-01-01
By the Decree of the Committee of Standards, Measures and Measuring Instruments under the Council of Ministers of the USSR of February 7, 1969 N 168, the introduction date was set from 01.01.71
Reissue. March 2004
1. This standard applies to identification coloring, warning signs and marking plates of pipelines (including connecting parts, fittings, fittings and insulation) at designed, newly built, reconstructed and existing industrial enterprises inside buildings, at outdoor installations and communications located on overpasses and in underground channels in order to quickly determine the contents of pipelines and facilitate the management of production processes, as well as ensuring labor safety.
The standard does not apply to the identification coloring of pipelines and ducts with electrical wiring.
2. The following ten enlarged groups of substances transported through pipelines are established:
1) water;
3) air;
4) combustible gases (including liquefied gases);
5) non-flammable gases (including liquefied gases);
6) acids;
7) alkalis;
8) combustible liquids;
9) non-flammable liquids;
0) other substances.
3. Identification coloring and digital designation of enlarged groups of pipelines must correspond to those indicated in Table 1.

4. Characteristics of colors of identification coloring should correspond to those specified in Appendix 1.
5. Fire-fighting pipelines, regardless of their content (water, foam, steam for extinguishing a fire, etc.), sprinkler and deluge systems in the areas of shut-off and control valves and at the points of connection of hoses and other fire extinguishing devices must be painted red (signal).
If it is necessary to indicate the contents of fire-fighting pipelines, it is allowed to additionally designate them by means of marking plates painted in the appropriate distinctive colors.
6. Identification painting of pipelines should be carried out continuously over the entire surface of communications or in separate sections.
The method for performing identification painting should be selected depending on the location of the pipelines, their length, diameter, the number of lines located together, safety and industrial sanitation requirements, lighting conditions and visibility of pipelines for maintenance personnel and the general architectural solution.
It is recommended to paint pipelines in sections in workshops with a large number and length of communications, as well as in cases where, due to the increased requirements for color rendering and the nature of the architectural solution of the interior, a concentration of bright colors is undesirable due to working conditions.
Identification painting over the entire surface of pipelines is recommended for use with a small length and a relatively small number of communications, if it does not worsen working conditions in the shops.
On outdoor installations, it is recommended to use identification coloring over the entire surface only in cases where this does not cause deterioration of operating conditions due to the effect of solar radiation on communications.
7. When applying identification coloring in sections to pipelines located inside industrial premises, it is recommended to paint the rest of the communications surface in the color of walls, partitions, ceilings and other interior elements against which the pipelines are located. At the same time, it is not allowed to paint pipelines between sections with an identification color adopted to designate other enlarged groups of substances.
8. When applying identification coloring in sections to pipelines located outside buildings, it is recommended to paint the rest of the communications surface in colors that help reduce the thermal effect of solar radiation on pipelines.
9. When laying communications in impassable channels and when laying communications without channels, areas of identification coloring on pipelines should be applied within the chambers and manholes.
10. Areas of identification coloring should be applied, taking into account local conditions, at the most critical communication points (at branches, at joints, flanges, at points of selection and instrumentation, at places where pipelines pass through walls, partitions, ceilings, at inputs and outputs from industrial buildings, etc.) at least 10 m inside production facilities and outdoor installations and 30-60 m on external main routes.
11. The width of the areas of identification coloring should be taken depending on the outer diameter of the pipelines (including insulation):
for pipes with a diameter of up to 300 mm - at least four diameters;
for pipes with a diameter of more than 300 mm - at least two diameters.
With a larger number of parallel communications, it is recommended that the areas of identification coloration on all pipelines be of the same width and applied at the same intervals.
With large diameters of pipelines, areas of identification coloring may be applied in the form of strips with a height of at least 1/4 of the pipeline circumference.
The width of the strips must correspond to the dimensions established for pipelines of a given diameter.
12. To designate the most hazardous substances transported by properties, warning color rings should be applied to pipelines.
Identification colors for warning rings must correspond to those indicated in Table 2.
table 2
Signal color samples | Name of signal colors | Properties of the transported substance |
| Flammable, flammable and explosive |
|
| Danger or harmfulness (poison, toxicity, ability to cause asphyxiation, thermal or chemical burns, radioactivity, high pressure or deep vacuum, etc.) |
|
| Security or Neutrality |
Notes:
1. When applying yellow rings for identification coloring of pipelines of gases and acids, the rings must have black borders with a width of at least 10 mm.
2. When applying green rings for the identification color of water pipelines, the rings must have white borders with a width of at least 10 mm.
13. In cases where a substance simultaneously has several dangerous properties, indicated by different colors, rings of several colors should be applied to pipelines at the same time.
On vacuum pipelines, in addition to the distinctive color, it is necessary to give the inscription "vacuum".
14. According to the degree of danger to human life and health or the operation of the enterprise, substances transported through pipelines should be divided into three groups, indicated by the corresponding number of warning rings in accordance with Table 3.

GOST 14202 - 69
Group G19
By the Decree of the Committee of Standards, Measures and Measuring Instruments under the Council of Ministers of the USSR dated February 7, 1969 N 168, the introduction date was set from 01.01.71.
1. This standard applies to identification coloring, warning signs and marking plates of pipelines (including connecting parts, fittings, fittings and insulation) at designed, newly built, reconstructed and existing industrial enterprises inside buildings, at outdoor installations and communications located on overpasses and in underground channels in order to quickly determine the contents of pipelines and facilitate the management of production processes, as well as ensuring labor safety.
The standard does not apply to the identification coloring of pipelines and ducts with electrical wiring.
2. The following ten enlarged groups of substances transported through pipelines are established:
3) air;
4) combustible gases (including liquefied gases);
5) non-flammable gases (including liquefied gases);
6) acids;
7) alkalis;
8) combustible liquids;
9) non-flammable liquids;
10) other substances.
3. Identification coloring and digital designation of enlarged groups of pipelines must correspond to those indicated in Table. 1.
| Table 1 | ||
| Substance being transported | Samples and name of colors of identification coloring | |
| Group number | Name | |
| 1 | Water | Green |
| 2 | Steam | Red |
| 3 | Air | Blue |
| 4 5 | combustible gases Non-flammable gases | Yellow |
| 6 | acids | Orange |
| 7 | alkalis | Violet |
| 8 9 | Flammable liquids Non-flammable liquids | Brown |
| 10 | Other substances | Grey |
4. Characteristics of colors of identification coloring should correspond to those specified in Appendix 1.
5. Fire pipelines, regardless of their contents (water, foam, steam for extinguishing a fire, etc.), sprinkler and deluge systems in the areas of shut-off and control valves and at the points of connection of hoses and other devices for extinguishing a fire, must be painted red (signal).
If it is necessary to indicate the contents of fire-fighting pipelines, it is allowed to additionally designate them by means of marking plates painted in the appropriate distinctive colors.
6. Identification painting of pipelines should be carried out continuously over the entire surface of communications or in separate sections.
The method for performing identification painting should be selected depending on the location of the pipelines, their length, diameter, the number of lines located together, safety and industrial sanitation requirements, lighting conditions and visibility of pipelines for maintenance personnel and the general architectural solution.
It is recommended to paint pipelines in sections in workshops with a large number and length of communications, as well as in cases where, due to the increased requirements for color rendering and the nature of the architectural solution of the interior, a concentration of bright colors is undesirable due to working conditions.
Identification painting over the entire surface of pipelines is recommended for use with a small length and a relatively small number of communications, if it does not worsen working conditions in the shops.
On outdoor installations, it is recommended to use identification coloring over the entire surface only in cases where this does not cause deterioration of operating conditions due to the effect of solar radiation on communications.
7. When applying identification coloring in sections to pipelines located inside industrial premises, it is recommended to paint the rest of the communication surface in the color of walls, partitions, ceilings and other interior elements against which the pipelines are located. At the same time, it is not allowed to paint pipelines between sections with an identification color adopted to designate other enlarged groups of substances.
8. When applying identification coloring in sections to pipelines located outside buildings, it is recommended to paint the rest of the communications surface in colors that help reduce the thermal effect of solar radiation on pipelines.
9. When laying communications in impassable channels and when laying communications without channels, areas of identification coloring on pipelines should be applied within the chambers and manholes.
10. Areas of identification painting should be applied, taking into account local conditions, at the most critical communication points (at branches, at joints, flanges, at points of selection and instrumentation, at places where pipelines pass through walls, partitions, ceilings, at inputs and outputs from industrial buildings, etc.) at least 10 m inside the production premises and at outdoor installations and every 30 - 60 m on external main routes.
11. The width of the areas of identification coloring should be taken depending on the outer diameter of the pipelines (including insulation):
for pipes with a diameter of up to 300 mm - at least four diameters;
for pipes with a diameter of more than 300 mm - at least two diameters.
With a larger number of parallel communications, it is recommended that the areas of identification coloration on all pipelines be of the same width and applied at the same intervals.
With large diameters of pipelines, areas of identification coloring may be applied in the form of strips with a height of at least 1/4 of the pipeline circumference.
12. To designate the most hazardous transported substances, warning color rings should be applied to pipelines.
The colors of the identification color for warning rings must correspond to those indicated in Table. 2.
| table 2 | ||
| Signal color samples | Name of signal colors | Property of the transported substance |
| Red | Flammable, flammable and explosive | |
| Yellow | Danger or harmfulness (poison, toxicity, ability to cause asphyxiation, thermal or chemical burns, radioactivity, high pressure or deep vacuum, etc.) | |
| Green | Security or Neutrality | |
Notes.
1. When applying yellow rings for identification coloring of pipelines of gases and acids, the rings must have black borders with a width of at least 10 mm.
2. When applying green rings for the identification color of water pipelines, the rings must have white borders with a width of at least 10 mm.
13. In cases where a substance simultaneously has several dangerous properties, indicated by different colors, rings of several colors should be applied to pipelines at the same time.
On vacuum pipelines, in addition to the distinctive color, it is necessary to give the inscription "vacuum".
14. According to the degree of danger to human life and health or the operation of the enterprise, substances transported through pipelines should be divided into three groups, indicated by the corresponding number of warning rings in accordance with Table. 3.
15. Characteristics of signal colors must comply with those specified in Appendix 2.
16. The width of the warning rings and the distance between them must be taken depending on the outer diameter of the pipelines in accordance with Fig. 1 and table. 4.
17. With a large number of parallel communications, warning rings on all pipelines should be taken to be of the same width and applied at the same intervals.
18. Gas outlet lines and venting to the atmosphere, depending on their contents, must have an identification color established for the symbolic designation of enlarged groups, with winding transverse rings of the corresponding signal color.
19. To designate pipelines with content that is especially dangerous to human health and life or the operation of an enterprise, and if necessary, to specify the type of danger, warning signs should be used in addition to color warning rings.
20. Warning signs should indicate the following substances: poisonous, flammable, explosive, radioactive, as well as other dangerous contents of pipelines (for example, substances that are hazardous when splashed, etc.).
21. Warning signs must be in the form of a triangle. Images must be black on a yellow background.
