The purpose of this document is to specify:
the dimensional, hygiene, tightness, pressure performance, hydraulic, acoustic, mechanical and
physico-chemical characteristics which inlet valves for flushing cisterns shall comply with;
the test methods for testing these characteristics;
marking and presentation.
This document applies exclusively to the valve itself and it does not prejudge compliance with health regulations as
the inlet valve is being fitted into the cistern.
This document does not cover valves intended to equip flushing cisterns with external overflow.
This document applies to valves such as float valves limit operating at pressures up to NP 10 (whose operating
range is from 0,05 MPa to 1 MPa ¿ 0,5 bar to 10 bar) designed to supply cold water to flushing cisterns for use with
WC pans, that are permanently connected to a potable water supply system.
The working range can be extended downwards (< 0,05 MPa ¿ 0,5 bar) down to 0,01 MPa (0,1 bar), in which case
the manufacturer¿s instructions shall indicate this possibility as well as the recommended working range.
Range which shall be covered
Optional range
This document does not apply to valves used for other applications: pumping tanks, storage tanks, etc.
Diese Europäische Norm legt konstruktive und funktionelle Anforderungen hinschtlich Maßen, Hygiene, Dichtheit, Druckbeständigkeit, hydraulischer Eigenschaften, Geräuschverhalten, mechanischer Festigkeit und physikalisch-chemischer Eigenschaften, denen die Füllventile für Spülkästen entsprechen müssen, fest.
