This publication establishes a program for marking a service date on compressed gas regulators intended for use in welding, cutting, and allied processes. It also informs end users and the regulator service repair industry of actions they should take to properly mark and maintain regulators. This program can be applied to regulators used in other applications such as specialty gas, etc.

Customer-specified regulators, original equipment manufacturer (OEM), and special application regulators may be excluded as agreed upon by the manufacturer and the customer.
