The EN 1074 standard, which is a European standard, consists of the following subsections under the main heading "Valves for water supply - Requirements for fitness for purpose and appropriate verification tests":
The EN 1074-1 standard defines minimum fitness for purpose requirements for valves used in or connected to above-ground or underground water supply piping systems. The standard EN 805 Water supply - Requirements for systems and components outside buildings also applies. Incidentally, this part is suitable for raw or processed piping systems, for example for irrigation and firefighting.
The EN 1074-2 standard defines minimum fitness for purpose requirements for isolation valves used in or connected to above-ground or underground water supply piping systems. The standard EN 805 Water supply - Requirements for systems and components outside buildings also applies. Incidentally, this part is suitable for raw or processed piping systems, for example for irrigation and firefighting.
The EN 1074-3 standard defines minimum fitness for purpose requirements for check valves that carry water for human consumption, are used in or connected to above-ground or underground water supply piping systems. The standard EN 805 Water supply - Requirements for systems and components outside buildings also applies. This section describes the design requirements, performance requirements and conformity assessment method for check valves, regardless of type and material. This section applies primarily to any product or test standard. Requirements in other standards apply only when this standard refers to them.
The EN 1074-4 standard describes minimum fitness for purpose requirements for air valves used in or connected to surface or underground water supply piping systems carrying water for human consumption. The standard EN 805 Water supply - Requirements for systems and components outside buildings also applies. This section describes the design requirements, performance requirements and conformity assessment method for air valves, regardless of type and material. This section applies primarily to any other product or test standard. Requirements in other standards apply only when this standard refers to them. This section discusses the requirements applicable to air valves DN to DN 300 and PFA 6 to PFA 25.
The EN 1074-5 standard defines the specific requirements and test methods applicable to control valves in the range PN 6 to PN 25 with nominal dimensions as defined in the first chapter. Type tests are performed on valves with DN <= 500 by agreement between supplier and buyer for higher DNs. This section is not concerned with the performance of control valve accessories, whether or not they form an integral part of the valves.
The EN 1074-6 standard describes the minimum fitness for purpose requirements for hydrants used in or connected to above-ground or underground water supply piping systems carrying water for human consumption. The standard EN 805 Water supply - Requirements for systems and components outside buildings also applies. This section describes the design requirements, performance requirements and conformity assessment method for hydrants, whatever their type, material and function. Additional requirements may be sought in other standards where hydrants are used for firefighting, irrigation or other functions. This part of EN 1074' deals with requirements applicable to both underground and columnar hydrants in sizes DN 65 to DN 150 and PFA up to 16 bar. This section does not provide requirements for their interface with outlets or hydrants, as they are subject to national standards.
Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our company also provides appropriate verification test services for the valves used for water supply within the scope of the EN 1074 standard, within the framework of the suitability requirements, with its trained and expert staff and advanced technological equipment. .
