Updated Version of Important Safety Standard
The American Society of Mechanical Engineers (ASME) is a non-profit professional association that works to improve standards in the field of mechanical engineering. By promoting standards, training, and certification, ASME can improve engineering practices around the world.
ASME will work to develop engineering codes and standards that they recommend all American mechanical engineers adhere to in the field. As these codes are set, the American National Standards Institute (ANSI) can accredit the codes.
ANSI, after accrediting these codes and standards, can represent the interests of ASME in the international community, helping to keep American industry current with international standards and keeping products compatible with overseas counterparts.
Updating these standards periodically is critical, and standard A13.1 was recently updated. For pipe identification, the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) has been adopted into the standard.
GHS pictograms should be included in pipe labeling legends where piping is connected to containers of chemicals. These GHS labels help to better communicate potential physical, health, and environmental hazards than previous identification systems.
Another important update is to the designation of colors used for pipe identification. A new classification has been added for oxidizing fluids. An oxidizing fluid is classified as any gas or liquid that may, generally by providing oxygen, cause or contribute to the combustion of other material more than the atmosphere does.
Oxidizing fluids should be marked with the color combination of black letters on a yellow background.
As part of the updated ANSI/ASME A13.1 2015 standard, no changes were made to pipe identification size requirements for diameter, marker size, and letter height or installation.
