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.

This document specifies the requirements for the materials, design, fabrication, erection, testing and inspection of site built, vertical, cylindrical, flat bottomed, above ground, welded, steel tanks for the storage of liquids at ambient temperatures and above. It is concerned with the structural design of the basic tank structure and does not provide requirements for considering process design, operational issues, safety and firefighting facilities, in-service inspection, maintenance, or repair. This document is intended for use in conjunction with EN 1993-4-2 and so adheres the general principles and performance requirements for the structural design and serviceability limit states of those tank components. Specific requirements are addressed in EN 14015. It is applicable to: – closed-top tanks, with and without internal floating roofs; – open-top tanks, with and without floating roofs; – tanks for which: a) the design pressure is not greater than 60 mbar; b) the design internal negative pressure is not lower than 6,0 mbar; c) the design metal temperature is between –40 °C and +300 °C; d) the maximum design liquid level is not higher than the top of the cylindrical shell; e) the maximum allowable stress does not exceed 260 N/mm2. The limits of application of this document terminate at the following locations: – face of the first flange in a bolted flange connection; – first threaded joint on the pipe or coupling outside of the tank shell, roof or bottom; – first circumferential joint in a pipe not having a flange connection. This document does not apply to tanks where the product is refrigerated to maintain it as a liquid at atmospheric pressure.

This document gives requirements and the corresponding test/assessment methods applicable to leak detector based on the measurement of pressure change. Leak detectors are intended to be used with double skin, underground or above ground, pressurized or non-pressurized, tanks or pipe designed for water polluting liquids/fluids. The leak detectors are usually composed of: - measuring device; - evaluation device; - alarm device; - pressure generator; - pressure relief device; - liquid stop device; - condensate trap.

This document gives requirements and the corresponding test/assessment methods applicable to leak detectors based on the drop of the liquid level in the leak detection liquid reservoir. Leak detectors are intended to be used with double skin, underground or above ground, non-pressurized tanks designed for water polluting liquids. The liquid leak detectors are usually composed of: - sensing device (liquid sensor); - evaluation device; - alarm device.

This document gives requirements and the corresponding test/assessment methods applicable to sensor-based leak detection systems (leak detectors) for liquids and/or for gases. The leak detectors are intended to be used in interstitial spaces, leakage containments or monitoring wells. The leak detectors are usually composed of: - sensing device(s); - evaluation device; - alarm device.

This document specifies requirements and the corresponding test/assessment methods applicable to leak detection linings and leak detection jackets. Leak detection linings and leak detection jackets are intended to be used, in conjunction with leak detection kits, to create an interstitial space or leakage containment in single skin underground or above ground, non-pressurized tanks designed for water polluting liquids. For leak detection kits, see EN 13160 2, EN 13160 3 and EN 13160 4.

This document provides additional terms and definitions to those written in the Agreement Concerning the International Carriage of Dangerous Goods by Road (ADR) or the Regulations concerning the International Carriage of Dangerous Goods by Rail (RID), appearing as Appendix C to the Convention concerning International Carriage by Rail (COTIF). This document forms part of series of documents prepared by CEN/TC 296 regarding the transport of dangerous goods. The series supports the proper application of the ADR and RID. This document is applicable to tanks used for the transport of dangerous goods. This document does not apply to carriage in bulk of dangerous goods. For convenience, Annex A (informative) repeats some horizontal definitions taken from ADR and RID 2025 chapter 1.2, and Annex B (informative) repeats some definitions from ADR and RID 2025 chapter 6.7, specific to portable tanks. NOTE The ADR and RID are updated on a regular basis, therefore Annexes A and B might become out of date. For outdated definitions, the RID/ADR take precedence. Annexes C, D and E (informative) provide alphabetical trilingual indexes of terms in English, French and German where the key is English, French and German respectively. Annex F (normative) is a schematic diagram of tank openings and closures according to the tank code.
