Standards
This document specifies the general requirements
for the competence, impartiality and consistent operation of laboratories. It is
applicable to all organizations performing laboratory activities, regardless of
the number of personnel.
Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use this document in confirming or recognizing the competence of laboratories.
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 International Standard contains requirements for the competence of bodies performing inspection and for the impartiality and consistency of their inspection activities. It applies to inspection bodies of type A, B or C, as defined in this International Standard, and it applies to any stage of inspection.
NOTE The stages of inspection include design stage, type examination, initial inspection, in-service inspection or surveillance.
This International Standard contains requirements for the competence, consistent operation and impartiality of product, process and service certification bodies. Certification bodies operating to this International Standard need not offer all types of products, processes and services certification. Certification of products, processes and services is a third-party conformity assessment activity (see ISO/IEC 17000:2004, definition 5.5).
In this International Standard, the term “product” can be read as “process” or “service”, except in those instances where separate provisions are stated for “processes” or “services” (see Annex B).
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.
