Potential fields of application and their application standards that apply together with this document are listed below: — applications with a maximum allowable pressure PS greater than 0,5 bar in accordance with the European legislation for pressure equipment, the applicable provisions of EN 16668 apply; NOTE 1 Exclusions are given in the European legislation for pressure equipment. — chemical applications, the applicable provisions of EN 12569 apply; — gas distribution systems, the applicable provisions of EN 13774 apply; — water supply application, the provisions of EN 1074-1 and EN 1074-2 apply; — process control application, the provisions of EN 1349 and EN 60534-2-1 apply. NOTE 2 The minimum requirements specified in Clauses 4, 5, 6, 7.1 and 8 are considered as "sound engineering practice" and are to be taken into account to ensure safe use. NOTE 3 The range of DN, applicable to each PN, for wafer and wafer lug valve types is as given in the appropriate part of EN 1092 for Type 11 flanges for the applicable material. The range of DN, applicable to each PN, for flanged valve types is as given in the appropriate part of EN 1092 for Type 21 flanges for the applicable material. The correspondence between DN and NPS is given for information in Annex D.

This document specifies the properties of the piping system and its components made from glass-reinforced thermosetting plastics (GRP) based on unsaturated polyester resin (UP). It is suited for all types of water supply, drainage and sewerage with or without pressure. Types of water supply include, but are not limited to, raw water, irrigation, cooling water, potable water, salt water, sea water, penstocks in power plants, processing plants and other water-based applications.

This document is applicable to GRP-UP piping systems, with flexible joints, intended to be installed using jacking techniques. It specifies the characteristics of pipes made from GRP-UP, with or without aggregates or fillers and also specifies the test parameters for the test methods referred to in this document.

The requirements for the hydrostatic pressure design of pipes referring to this document meet the requirements of ISO/TS 20656-1 and the general principle for the reliability of structures detailed in ISO 2394 and in EN 1990. These documents provide procedures for the harmonization of design practices and address the probability of failure, as well as possible consequences of failures. The design practices are based on a partial safety factor concept, as well as on risk management engineering.

This document is applicable to circular pipes and joints with a size range from DN 100 to DN 4000 at normal service conditions.

It covers requirements to prove the design of the joint and specifies type test performance requirements for the joints as a function of the declared nominal pressure rating of the pipeline system and the required joint deflection capability of the system.

GRP-fittings, used between pipe systems covered by this document, shall be in accordance with ISO 23856. In a pipe-work system, pipes of different nominal pressure and stiffness ratings may be used together.

This document specifies the design, testing and marking requirements for spring loaded pressure relief valves (PRV), for use in liquefied petroleum gas (LPG) cylinders of water capacity of 0,5 l up to and including 150 l. These PRVs can be either an integral part of a cylinder valve (see EN ISO 14245 [4] and EN ISO 15995 [5]) or a separate device.

This European Standard specifies the objectives for drain and sewer systems outside buildings. It specifies the functional requirements for achieving these objectives and the principles for strategic and policy activities relating to planning, design, installation, operation, maintenance and rehabilitation. It is applicable to drain and sewer systems from the point where wastewater leaves a building, roof drainage system, or paved area, to the point where it is discharged into a wastewater treatment plant or receiving water body. The standard pays regard to the extremes of our changing climate and seeks to aknowledge the associated impacts on existing drain and sewer systems outside of buildings and futureproof associated aspects of those systems that are to be planned for and designed in the future. Drains and sewers below buildings are included provided that they do not form part of the drainage system for the building.

This document specifies requirements for tests, test procedures and acceptance criteria for production testing of industrial valves made of metallic materials. NOTE The specified tests can also be used as type tests or acceptance tests. This document does not apply to: - industrial valves of thermoplastic materials; - safety valves and bursting discs (safety accessories); - sight glass with its frames (component of a pressure equipment). When specified as a normative reference in a valve product or performance standard, this document is to be considered in conjunction with given specific requirements of the valve product or performance standard. Where requirements in a product or performance standard differ from those given in this document, the requirements of the product or performance standard apply.

This document specifies requirements for an experimental method to prove that representative samples of valve shells and their body ends, made in cast iron, steel or copper alloy materials, are designed to possess the required pressure containing capability, with an adequate margin of safety. This document is not applicable to valves designed on the basis of time dependent strength values (creep) or valves designed for pulsating pressure applications (fatigue). For valves in the scope of the European legislation for pressure equipment, the sole use of an experimental method is only permitted when the maximum allowable pressure at room temperature, PS, multiplied by the DN-number is less than 3 000 bar. This document is used to supplement the tabulation method EN 12516-1:2014+A1:2018, and the calculation method EN 12516-2:2014+A1:2021 without limit.
