Hydrauliske systemer og komponenter til Allmenn bruk

This European Standard specifies: a) the field of application; b) the requirements of hose union anti vacuum valves; c) dimensional and physio-chemical properties, and properties of general hydraulic, mechanical and acous-tic design of hose union anti-vacuum valves of nominal sizes DN 15 up to and including DN 25; d) marking and technical product information. This standard specifies the characteristics of hose union anti-vacuum valves of nominal size DN 15 up to and including DN 25 that are suitable for use in drinking water systems at pressures up to and including 1 MPa (10 bar) and temperatures up to and including 65 °C and for 1 h at 90 °C. HB protects against back siphonage only and should be installed in vertical downward flowposition. HB and HD anti-vacuum valves are for installation exclusively at the connecting point between stop valve and hose in vertical downward flow position.

This part of EN 13476, together with EN 13476 1, specifies the definitions and requirements for pipes, fittings and the system based on unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) structured-wall piping systems that are intended to be used for non-pressure underground drainage and sewerage systems. This part is applicable to pipes and fittings with smooth internal and profiled external surfaces, designated as Type B. It specifies test methods and test parameters as well as requirements. This part is applicable to: a) structured-wall pipes and fittings, which are intended to be used buried underground outside the building structure, reflected in the marking of products by "U"; b) structured-wall pipes and fittings, which are intended to be used buried underground both outside (application area code "U") and within the building structure (application area code "D"), reflected in the marking of products by "UD". This part is applicable to structured-wall pipes and fittings with or without an integral socket with elastomeric ring seal joints as well as welded and fused joints. This part covers a range of pipe and fitting sizes, materials, pipe constructions, stiffness classes, application classes, and tolerance classes and gives recommendations concerning colours. NOTE It is the responsibility of the purchaser or specifier to make the appropriate selections from these aspects, taking into account their particular requirements and any relevant national regulations and installation practices or codes.

Amends annex A

This document gives requirements for specification and acceptance conditions of raw materials for GRP tanks and vessels with or without lining for storage or processing of fluids, factory made or site built, non-pressurised or pressurised, for use above ground. Tanks and vessels for storage or processing of food, raw materials for food and potable water additionally have to be in compliance with relevant EU directives and applicable national standards and regulations.

The vocabulary in ISO 7369:2004 is out of date and that this standard needs to be revised to update the definitions in accordance to EN ISO 10380, EN 14585 and the PED (Pressure Equipment Directive). Revision of EN ISO 7369:2004 under VA/CEN lead with Eric Winterbert as project leader is accepted by ISO/TC 5/SC 11 (Resolution 1/2016). The exact scope of the revision will be clarified by the project group before launching the NWIP ballot.

This Part 12 of EN 13445 series specifies requirements for unfired pressure vessels and their parts made of copper and copper alloys (see 5.2) in addition to the general requirements for unfired pressure vessels in EN 13445-1:2014 to EN 13445-5:2014. NOTE 1 Cast materials are not included in this version. Details regarding cast materials will be subject to an amendment to or a revision of EN 13445 series. NOTE 2 Soldered connections are presently not considered.
