ASME A112.19.15:2001 pdf free download Erratum to ASME A112.19.15-2001 Bathtub/Whirlpool Bathtubs With Pressure Sealed Doors
GENERAL1.1 Scope
This Standard cstablishcs matcrial,mechauical, elec-trical，marking,and testing requiremcnts for bathtubslwhirlpool bathtubs with doors that are made water tightby the use of a pressure seal. It addresses the functionalperformance and physical characteristics for a pressuresealed door of a bathtub/whirlpool bathtub.
The door is intended to ailow for entry into thefixture when the tub is empty.and maintains watertightness when the lub is fuil.
The use of alternate maierials or methods are permit-ted,provided the proposed material and method com-plies with the performance requirements and intent ofthis Standard.
1.2 Units of Measurement
Values are stated in U.s. Customary units and theInternational System of Units (SI). The U.s. Customaryunits shall be considered as the standard.
