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.

Butt-welding pipe fittings - Part 4: Wrought austenitic and austenitic-ferritic (duplex) stainless steels with specific inspection requirements
EN 10253-4:2025

This document specifies the technical delivery requirements for seamless and welded butt-welding fittings (elbows, concentric and eccentric reducers, equal and reducing tees, caps) made of austenitic and austenitic-ferritic (duplex) stainless steel in two test-categories which are intended for pressure purposes at room temperature, at low temperature or at elevated temperatures, and for the transmission and distribution of fluids and gases.
It specifies:
a)   type of fittings;
1)   type A: butt-welding fittings with reduced pressure factor;
2)   type B: butt-welding fittings for use at full service pressure;
b)   steel grades and their chemical compositions;
c)   mechanical properties;
d)   dimensions and tolerances;
e)   requirements for inspection and testing;
f)   inspection documents;
g)   marking;
h)   protection and packaging.
NOTE   The selection of the appropriate fitting (material, thickness) is the ultimate responsibility of the manufacturer of the pressure equipment (see European Legislation for Pressure Equipment). In the case of a harmonized supporting standard for materials, presumption of conformity to the ESRs is limited to technical data of materials in the standard and does not presume adequacy of the material to a specific item of equipment. Consequently, it is essential that the technical data stated in the material standard be assessed against the design requirements of this specific item of equipment to verify that the ESRs of the PED are satisfied.
