This Standard establishes material, mechanical, electrical, marking, and testing requirements for bathtubs/ whirlpool bathtubs with doors that are made water tight by the use of a pressure seal. It addresses the functional performance and physical characteristics for a pressure sealed door of a bathtub/whirlpool bathtub. The door is intended to allow for entry into the fixture when the tub is empty and to maintain water tightness when the tub is full.
