Standards
This document specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air which do not incorporate a flame (flashback) arrestor used downstream of manifold, cylinder and/or pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This document does not specify the location of these devices in the gas system. This document is not applicable to safety devices which incorporate a flame arrestor, covered by ISO 5175-1.
This standard applies to the storage and handling of portable containers used for storage of Liquefied Petroleum Gases (LPG) and to the transportation of these containers.
This part of ISO 15489 provides guidelines on managing records 1 of originating organizations, public or private, for internal and external clients.

This standard does not cover the storage, handling and transport of ammonia cylinders.
The main text of this national standard contains a list of these parameters, their units and references to measurement standards. Informative annexes give examples of typical values for these parameters, with the main emphasis on health and safety. In defining the parameters governing composition, physical properties and trace constituents, consideration has also been given to existing natural gases to ensure their continuing viability.
The question of interchangeability is dealt with in Annex A (see Clause A.2).
Fuel meeting the requirements of this part of ISO 15403 should:
(a) provide for the safe operation of the vehicle and associated equipment needed for its fuelling and maintenance;
(b) protect the fuel system from the detrimental effects of corrosion, poisoning, and liquid or solid deposition;
(c) provide satisfactory vehicle performance under any and all conditions of climate and driving demands.
Some aspects of this part of ISO 15403 may also be applicable for the use of natural gas in stationary combustion engines.
