NOM-009-ENER-1995: Energy efficiency in industrial thermal insulation systems

Last updated: 18 July 2019
This standard establishes the maximum permissible heat transfer levels with thermal insulation in high or low temperature systems in industrial installations. See the attachment for the maximum heat transfer levels.
The standard applies to new industrial thermal insulation systems, extensions and/or modifications, which operate at high and low temperature between a range of 198 K (-75 ° C) to 1088 K (815 ° C), considered as:
- High temperature service: operating temperature equal to or greater than 310 K (37 ° C).
- Low temperature service: operating temperature less than 310 K (37 ° C).
