This Standard specifies requirements for metallic taps, plastic taps, mixing taps, sensor taps, lever taps, time/flow taps, mixing taps mechanical (non-thermostatic), and tap sets in a range of nominal sizes from DN 6 to DN 50 generally for continuous operating temperatures not exceeding 80 degrees C.

This Standard specifies requirements for metallic taps, plastic taps, mixing taps, sensor taps, lever taps, time/flow taps, mixing taps mechanical (non-thermostatic), and tap sets in a range of nominal sizes from DN 6 to DN 50 generally for continuous operating temperatures not exceeding 80C. Products designed for other temperature ranges are included where tested to the appropriate temperature criteria. The Standard also specifies additional requirements for outlets that are an integral part of a tap or mixing tap and the requirements for tapset breaching piece assemblies. Means for demonstrating compliance with this Standard are given in Appendix A. NOTE: Certification under MP 52 is mandatory in Australia but not in New Zealand.
