13、5 ii BSI 20 January 2005 Foreword This Part of BS 5482 has been prepared by Technical Committee GSE/31. It supersedes BS 5482-1:1994 which is withdrawn, and partially supersedes BS 5482-2:1977. It has been revised to take into account current technology and practice. Legislation requires persons car

14、rying out work to have the required competence. The Gas Safety (Installation and Use) Regulations 1, 2 require any “work” on gas appliances, including their installation, that falls within their scope (i.e. most work outside of factories) to be carried out by a business which is a “member of a class

15、 of persons” approved for the time being by the Health and Safety Executive (HSE). NOTE At the time of publication, the body with HSE approval to operate and maintain a register of businesses who are “members of a class of persons” is the Council for Registered Gas Installers (CORGI). Thus it is ess

16、ential that all business or self employed gas fitters should be registered with CORGI. Guidance on the individual competency required for gas work is given in the Health and Safety Commissions Approved Code of Practice (ACOP) 3. As a code of practice, this British Standard takes the form of guidance

17、 and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct appli

18、cation. Compliance with a British Standard does not of itself confer immunity from legal obligations. Attention is drawn to the following statutory regulations: The Health and Safety at Work Act 1974. Gas Safety (Installation and Use) Regulations 1998 (SI 2451) 1. Gas Safety (Installation and Use) R

19、egulations (Northern Ireland) 1997 (SI 194) 2. Building Regulations 1991 (SI 2768) (as amended) 4. Building Standards (Scotland) Regulations 1990 (SI 2179) (as amended) 5. Building Regulations (Northern Ireland) 1990 (SR 59) (as amended) 6. NOTE 4, 5 and 6 do not apply to residential park homes. Sum

20、mary of pages This document consists of a front cover, an inside front cover, pages i and ii, pages 1 to 49 and a back cover. The BSI copyright notice displayed in this document indicates when the document was last issued.BS 5482-1:2005 BSI 20 January 2005 1 1 Scope This Part of BS 5482 gives guidan

21、ce and recommendations for the installation of liquefied petroleum gas (LPG) supply systems at permanent dwellings, including residential park homes, and small commercial premises, with installation pipework sizes not exceeding DN 25 for steel and DN 28 for corrugated stainless steel or copper. It a

22、pplies to systems using either commercial propane from cylinders or bulk supply at a pressure of 37 mbar, or commercial butane from cylinders at a pressure of 28 mbar. It makes recommendations on the selection of materials and components, on design considerations, on installation, on inspection and

23、testing and on user instructions. NOTE 1 Gas storage and distribution systems for multiple consumers are outside the scope of this standard. This standard does not cover the installation requirements of bulk tanks supplying LPG, for which guidance is given in LPGA Code of Practice 1, Parts 1, 2, and

24、 4.7. Appliances incorporating their own gas supply, such as mobile heaters, are not considered to be part of the installation and are thus outside the scope of this standard. NOTE 2 It is recognized that this standard may be referred to for LPG installations other than those concerned with domestic

25、 systems at permanent dwellings and residential park homes. In these instances it has to be borne in mind that other codes of practice, standards and regulations may apply. This standard does not cover leisure accommodation vehicles (see BS EN 1949). 2 Normative references The following referenced d
