This Part 11 of this European Standard specifies requirements for unfired pressure vessels and their parts made of titanium and titanium alloys in addition to the general requirements for unfired pressure vessels under EN 13445:2014 Parts 1 to 5. NOTE 1 Cast materials, HIP and additive manufacturing are not included in this version. Details regarding such materials will be subject to an amendment to or a revision of this European Standard. NOTE 2 Materials in Groups 51.4 and 54 are not included in this version.

This document specifies the general requirements for metallic check valves, which are forged, cast or fabricated in straight, angle or oblique pattern (see EN 736‐2) with end connections flanged or wafer, butt welding, socket welding, or threaded. This document applies to metallic check valves used for all industrial applications. Additional requirements given in the relevant application standards may apply to check valves used for more specific applications (e.g. for the water industry, the chemical and petrochemical process industry, the gas distribution industry). Sanitary check valves and back flow prevention anti-pollution check valves are excluded from the scope of this document. The range of nominal sizes covered is: - DN 8, DN 10; DN 12, DN 15; DN 20; DN 25; DN 32; DN 40; DN 50; DN 65; DN 80; DN 100; DN 125; DN 150; DN 200; DN 250; DN 300; DN 350; DN 400; DN 450; DN 500; DN 600; DN 700; DN 750; DN 800; DN 900; DN 1 000; DN 1 200. DN 8 and DN 12 are not used for PN designated flanged end connections. DN 8, DN 10 and DN 12 are not used for Class designated flanged end connections. DN 750 is used for Class designated check valves only. Socket welding end check valves and threaded end check valves are limited to the range DN 8 to DN 65. The range of pressure designations covered is: a) for flanged end and wafer type end cast iron bodies: - PN 2,5; PN 6; PN 10; PN 16; PN 25; - Class 125; Class 250; b) for flanged end, wafer type and butt welding end bodies in steel or copper alloy materials: - PN 2,5; PN 6; PN 10; PN 16; PN 25; PN 40; PN 63; PN 100; PN 160; PN 250; PN 320; PN 400; - Class 150; Class 300; Class 600; Class 900 ; Class 1 500; Class 2 500; c) for socket welding end and threaded end bodies in steel or copper alloy materials: - PN 40; PN 63; PN 100; - Class 600; Class 800. NOTE Class 800 is a widely used Class designation for socket welding and threaded end check valves. The correspondence between DN and NPS is given for information in Annex B.

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) manholes and inspection chambers intended for non-pressure underground drainage and sewerage systems to a maximum depth of 6 m from ground level to the invert of the manhole or inspection chamber. This document covers manholes and inspection chambers with flow profile bases, and their joints to the piping system. Manholes and inspection chambers are intended to be used in pedestrian or vehicular traffic areas outside the building structure. NOTE 1 The intended use in underground installation outside the building structure is reflected in the marking of products by the application area code "U". NOTE 2 Products complying with this document may also be used in non-traffic areas. NOTE 3 Products complying with this standard can be installed in underground applications without additional static calculation. NOTE 4 Shallow chambers are specified in EN 13598-1. Manholes and inspection chambers complying with EN 13598-2 are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together. NOTE 5 The complete manhole or inspection chamber assembly may also include non-plastic items (near surface or surface components for example) which are not covered by this document. NOTE 6 Manholes and inspection chambers may be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1]. Manholes and inspection chambers complying with EN 13598-2 comply with the general requirements given in EN 476. Manholes and inspection chambers complying with EN 13598-2 may be used for storm-water systems. Manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or fabricated. NOTE 7 Manholes and inspection chambers can be site assembled from different components, but can also be manufactured as a single unit.

This document specifies product characteristics, test/assessment methods and of how to express test/assessment results. Cast iron pipelines kits are usually composed by cast iron pipes, fittings, joints and accessories. This document covers the range of nominal diameter from DN /40 to DN 600 inclusive. The cast iron includes grey cast iron and ductile cast iron. The roof gullies used for siphonic systems are outside the scope of this standard. Sewerage applications are outside the scope of this standard. It is intended to be used for the construction of gravity or vacuum discharge pressurized or unpressurised networks installed inside and/or outside Works, above and/or below ground, in construction works.

This document specifies requirements for the design, material, manufacturing and testing of pressure vessels and pressure vessel parts made from materials for which details are specified from the following material standards for specific grades which meet the criterion of an elongation after fracture less than or equal to 15 %: - EN 1561:2011, Founding - Grey cast irons; - EN 1563:2018, Founding - Spheroidal graphite cast irons; - EN 13835:2012, Founding - Austenitic cast irons. NOTE The content of the vessel or pressure part is a fluid of group 2 only, according to Directive 2014/68/EU.
