This document specifies :
The dimensional, the physico-chemical, the design, the hydraulic, the mechanical and the acoustic characteristics of non-controllable backflow preventer with different pressure zones, family C, type A, nominal sizes DN 6 to DN 25, nominal pressure PN 10.
It is applicable to:
- Family C, type A, class "a" for general use: devices of class "a" shall be capable of working: at any pressure up to 1 MPa (10 bar); with any pressure variation up to 1 MPa (10 bar); at a supply temperature limit of 65 °C and 90 °C for 1 hour ;
- Family C, type A, class "b" for specific use: devices of class "b" shall be capable of working: at any downstream pressure up to 0,3 MPa (3 bar); with any downstream pressure variation up to 0,3 MPa (3 bar); at a supply temperature limit of 65 °C and 90 °C for 1 h; Class "b" devices shall be capable of operating: at any downstream pressure up to 300 kPa (3 bar), with any downstream pressure variation up to 300 kPa (3 bar) at a supply temperature limit of 65 °C and 90 °C for 1 h. Class "b" devices with specific hydraulic and
non-acoustic requirements and are intended to equip filling devices physically integrated into a sin- gle-function (heating) or dual- function (heating and domestic hot water) boiler.
It specifies also:
- test methods and requirements for verifying these characteristics ;
- marking ;
- presentation and the delivery
