7、itish Standard supersedes BS 7971-10:2004, which is withdrawn.Information about this documentText introduced or altered by Corrigendum No.1 is indicated in the text by tags. Minor editorial corrections are not tagged.This British Standard has been substantially revised in association with the HomeOf
8、fice. The aims of the revision were to amalgamate appropriate content fromBS 7971-1, BS 7971-2 and BS 7971-10, together with content from the HomeOffice publication, Flame retardant overalls standard for UK police (2008) 1.This British Standard contains public sector information licensed under the O
9、penGovernment Licence v2.0.This is a full revision of the standard and introduces requirements covering: innocuousness; sizing; pre-treatment processes; marking; user information; cleaning; modified resistance to chemicals; repeated resistance to heat transmission on exposure to flame; testing for f
10、lame spread after exposure to chemicals.Ergonomics is not included. Annex A explains the rationale for this decision.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are expressed in sentences in which the principal auxiliary verb
11、is“shall”.Commentary, explanation and general informative material is presented insmaller italic type, and does not constitute a normative element.Contractual and legal considerationsThis publication does not purport to include all the necessary provisions of acontract. Users are responsible for its
12、 correct application.Compliance with a British Standard cannot confer immunity from legalobligations.Attention is drawn to the following Directive: Personal Protective Equipment Directive (PPE), 89/686/EEC (as amended) 2.BRITISH STANDARDBS 7971-10:2014ii The British Standards Institution 2015Introdu
13、ctionCoveralls are used in specialist operational situations and in training to reducethe risk of injury to the user, who might be faced with threats such as heat,flame and the effects of certain liquids, which in some circumstances could alsobe burning liquids.Coveralls are intended to provide prot
14、ection for a limited period only. Theycover the whole body, excluding the head, hands and feet. A coverall isintended to be worn externally to other protective items, such as blunt traumaprotectors and body armour, base layer garments and duty clothing.In the period of time since the first publicati
15、on of the BS 7971 suite ofstandards, products in general use have evolved to reflect the changing threatand operational needs of the user. The Home Office publication, Flameretardant overalls standard for UK police (2008) 1, introduced additionaltesting methodology including the need for protection
16、from more penetrativechemical threats and repeated heat exposure. In the selection of coveralls,optimum protection has to be balanced with operational requirements in anenvironment where the option of increasing protection levels as a threatescalates might not be viable.Operational requirements were
17、 taken into account during the preparation ofthis revision, including an option for protection to be achieved by use ofcombined undergarment and outer layer systems, which has been included fromthe Home Office standard.NOTE As an aid to specifiers purchasing undergarments which do not fall into thed
18、efinition of “functional undergarment” in accordance with this standard, guidanceon suitable material and reference standards is given in Annex B.Principal changes between this and the previous edition are outlined in theForeword.1 ScopeThis British Standard specifies requirements and test methods f
19、or coveralls,which are to be used predominantly but not exclusively by police and prisonofficers in specialist operational situations and in training, and which areintended to provide protection against heat and flame and small volumes ofcertain liquids.It is applicable to single and two-piece garme
20、nts, single-layer garments,multi-layer garments and garment assemblies requiring use of a specificundergarment.This British Standard does not cover other protective features such aselectrostatic, cut or slash resistance.NOTE Civilian groups working alongside police or prison services in specialistop
21、erational situations might find by risk assessment that this standard offersadditional protection for such activities and threats not considered by otherstandards.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdocument and are indispensable for
