Description

This Standard specifies general requirements, test methods, and markings for whirlpool and air-jetted bathtubs and suction fittings used in hydromassage bathtub systems that incorporate a bathtub and circulation pump. The circulation pump can be with or without (a) a piping system; and (b) induction of air (which can be achieved by integral suction or through an air pump).
