MCAA, in conjunction with the UA, recently led the development of a new American National Standards Institute (ANSI) industry consensus standard on pressure testing safety. The new standard, ANSI/ASSP A10.35 Safety Requirements for Pressure Testing Steel and Copper Piping Systems, was published on October 16, 2020. The voluntary industry consensus standard is based largely on the MCAA Guide to Steel and Copper Piping System Pressure Testing Safety. The standard’s safety requirements address planning, procedures, checklists, and other items for both hydrostatic and pneumatic pressure testing on steel and copper piping systems.
