This document defines the requirements for design, manufacturing and testing of welded steel automotive Liquefied Petroleum Gas (LPG) containers, to be permanently attached to a motor vehicle, where the automotive LPG is to be used as a fuel in the vehicle.

This document lists the best available acute-toxicity data of gases taken from a search of the current literature to allow the classification of gases and gas mixtures for toxicity by inhalation.

This document specifies the requirements for valve protection caps and valve guards used on cylinders for liquefied, dissolved or compressed gases. Valve protection caps and valve guards are some of the options available to protect cylinder valves, including valves with integral pressure regulators (VIPRs) during transport. This document is applicable to valve protection caps and valve guards which inherently provide the primary protection of a cylinder valve. It can also be used to test other equipment (e.g., handling devices) attached to cylinder packages, even in cases where the cylinder valve is inherently able to withstand damage without release of the content. This document excludes protection devices for cylinders with a water capacity of 5 l or less and cylinders whereby the protection device is fixed by means of lugs welded or brazed to the cylinder, or is welded or brazed directly to the cylinder. This document does not cover valve protection for breathing apparatus cylinders. NOTE Small cylinders (e.g., medical cylinders) are commonly transported in an outer-packaging (e.g., pallet) to meet transport regulations. This document does not specify requirements that could be necessary to enable the valve protection device to be used for lifting the cylinder.

This document, in conjunction with ISO 10297 and ISO 14246, specifies design, type testing, marking and manufacturing tests, and examinations requirements for quick-release cylinder valves intended to be fitted to refillable transportable gas cylinders, pressure drums and tubes which convey: — non-toxic; — non-oxidizing; — non-flammable; and — non-corrosive; compressed or liquefied gases or extinguishing agents charged with compressed gases to be used for fire-extinguishing, explosion protection, and rescue applications. NOTE 1 The main application of such quick-release cylinder valves is in the fire-fighting industry. However, there are other applications such as avalanche airbags, life raft inflation and similar applications. NOTE 2 Where there is no risk of ambiguity, gas cylinders, pressure drums and tubes are addressed with the collective term “cylinders” within this document. This document covers the function of a quick-release cylinder valve as a closure. This document does not apply to quick-release cylinder valves for cryogenic equipment and for liquefied petroleum gas (LPG). This document does not apply to quick-release cylinder valves if used as the main closure of portable fire extinguishers because portable fire extinguishers are not covered by transport regulation. Quick-release cylinder valves of auxiliary refillable propellant gas cylinders used within or as part of portable fire extinguishers are covered by this document, if these cylinders are transported separately, e.g. for filling (see UN Model Regulations, Chapter 3.3, Special Provision 225, second note[1]).

This document specifies design, type testing, marking and manufacturing tests and examinations requirements for: a) self-closing cylinder valves; b) self-closing cylinder valves with integrated pressure regulator (VIPR); NOTE 1 This includes VIPR designs where the primary valve operating mechanism is located upstream of the pressure regulating system (VIPR type A) and where the primary valve operating mechanism is located at the low-pressure side of the pressure regulating system (VIPR type C). NOTE 2 This does not include VIPR designs where the pressure regulating system is acting as the primary valve operating mechanism (VIPR type B) and designs where closure of the primary valve operating mechanism is obtained by closing the seat of the pressure regulating mechanism. Such designs are covered by ISO 10297. for refillable transportable gas cylinders which convey compressed, liquefied or dissolved gases. NOTE 3 The main applications for such self-closing cylinder valves are in the calibration gas and beverage industries. NOTE 4 Where there is no risk of ambiguity, cylinder valves and VIPRs are addressed with the collective term “valves” within this document. This document does not apply to: — valves for cryogenic equipment, portable fire extinguishers and liquefied petroleum gas (LPG); — quick-release cylinder valves (e.g. for fire-extinguishing, explosion protection and rescue applications) - requirements for quick-release cylinder valves are specified in ISO 17871 which contains normative references to this document; — ball valves. NOTE 5 Requirements for valves for cryogenic vessels are specified in ISO 21011 and at a regional level, e.g. in EN 1626. Requirements for valves for portable fire extinguishers are specified at a regional level, e.g. in EN 3 series. Requirements for self-closing LPG cylinder valves are specified in ISO 14245. Requirements for quick-release cylinder valves are given in ISO 17871. Requirements for ball valves are given in ISO 23826. This document only covers the function of a valve as a closure. Other functions that are possibly integrated in the valve can be covered by other standards. Such standards do however not constitute requirements according to this document. NOTE 6 Definition of and specific requirements for VIPRs in addition to those that are given in this document are specified in ISO 22435 for industrial applications or ISO 10524-3 for medical applications. Similarly, certain specific additional requirements for residual pressure valves (RPV) are given in ISO 15996.
