This document acknowledges the field of application for taps, shower outlets, shower sets and shower systems used in water supply systems with a pressure range of (0,05 to 1,0) MPa [(0,5 to 10) bar]. The tests described in this document are type tests (laboratory tests) and not quality control tests carried out during manufacture. This document covers: — PN10 taps; — PN5 shower outlets; — PN5 shower sets; — PN10 shower systems. The following products are excluded from this document: — shower taps on its own; — taps for filling bathtubs; — the tub filling function of combined taps; — the function of a tap that delivers e.g. boiling water or sparkling water, etc.; — body or side jet showers. The conditions of use for taps and shower systems are given in Table 1. The conditions of use for showers sets and shower outlets are given in Table 2.
