This European Standard specifies:
a) the field of application for pillar taps, bib taps, single and multi-hole combination taps for use in:
1) a supply system of Type 1 (see Figure 1);
2) a supply system of Type 2 (see Figure 2);
b) the dimensional, leaktightness, pressure resistance, hydraulic performance, mechanical strength, endurance and acoustic characteristics of nominal size ½ and ¾ single taps and combination taps;
c) test methods to verify the characteristics.
The tests described in this European Standard are type tests (laboratory tests) and not quality control tests carried out during manufacture.
This European Standard applies to draw-off taps (single taps and combination taps) for use with sanitary appliances installed in rooms used for bodily hygiene (cloakrooms, bathrooms etc.) and in kitchens, i.e. for use with baths, wash basins, bidets, showers and sinks.
Figure 1 shows a supply system of Type 1 with a pressure range of (0,05 to 1,0) Mpa [(0,5 to 10) bar].
Figure 2 shows a supply system of Type 2 with a pressure range of (0,01 to 1,0) Mpa [(0,1 to 10) bar].
This European Standard applies to sanitary draw-off taps of nominal size ½ and ¾ (PN 10).
The conditions of use and classifications are given in Table 1. The Table 2 gives the performance characteristics to be noted if the tap is used outside the recommended operating range.
