8、 of BS 7971 supersedes BS 7971-6:2003, which is withdrawn.Information about this documentThis part of BS 7971 has been substantially revised in association with the HomeOffice. The aims of the revision were to amalgamate appropriate content fromBS 7971-1, BS 7971-2, BS 7971-7 and BS 7971-6 and to re

9、ference the Home Officepublication, Slash resistance standard for UK police (2006) N1. This BritishStandard contains public sector information licensed under the OpenGovernment Licence v2.0.This full revision of the standard introduces the following principal changes byaddition of clauses covering:

10、innocuousness; sizing; marking; user information; cleaning; modified resistance to chemicals; and a high cut resistance test.Presentational conventionsThe provisions of this standard are presented in roman (i.e. upright) type. Itsrequirements are expressed in sentences in which the principal auxilia

11、ry verb 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.

12、 for its correct application.Compliance with a British Standard cannot confer immunity from legalobligations.Attention is drawn to Regulation (EU) 2016/4251)1.1)Regulation (EU) 2016/425 replaces Directive 89/686/EEC, which remains in use untilApril 2018.BRITISH STANDARDBS 7971-6:2016ii The British S

13、tandards Institution 2016IntroductionGloves used in general duty, specialist operational situations and in training areintended to reduce the risk of injury to a user who might be faced with threatssuch as various mechanical injuries, heat, flame and the effects of certain liquids,which in some circ

14、umstances may also be burning liquids.Public order gloves in particular are intended to provide protection againstspecific operational threats and are intended to be worn in conjunction withflame retardant overalls as described in BS 7971-10.In the selection of suitable gloves, optimum protection ha

15、s to be balanced withoperational requirements in an environment where the option of increasingprotection levels as threat escalates might not be viable.Operational requirements were taken into account during the preparation ofthis revision. The revision committee made the decision to incorporate dif

16、ferentlevels of protection for different activities into this single standard, allowingBS 7971-7 to be withdrawn.Principal changes between this and earlier editions are outlined in theForeword.1 ScopeThis part of BS 7971 specifies requirements and test methods for two types ofgloves, general duty gl

17、oves and public order gloves intended to be used forspecialist operational activities such as public order situations and public ordertraining.They are intended to provide protection against different hazards such asmechanical risk, heat and flame and small volumes of certain liquids.NOTE If the ris

18、k assessment of other specialist gloves identifies hazards covered bythis standard then in addition to any specific test requirements they might have,elements from this standard can be referenced.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in thisdo

30、nce with 4.4.2.2, there shall be no penetration of liquidthrough the structure of the glove after 10 min and no more than slight visibledamage to the surface, fittings or structure of the glove after 1 h.4.4.2.2 Chemical resistance testing4.4.2.2.1 PrincipleWhole glove samples are exposed for a shor

31、t period of time to a limited volumeof specific liquids which might be encountered in operational use.Damage to the materials and structure of the glove including ingress throughseams and manufactured structure is assessed following a short and thenextended period.4.4.2.2.2 MethodA single glove samp

32、le shall be evaluated per chemical to be applied.a) Clean the glove with a dry absorbent paper to remove any residue ormanufacturing finishes.b) Store the glove for at least 24 h in an environment at 20 2 Cand 65 5% rh.c) Fasten the glove.d) Fill the glove with absorbent paper as a trace medium for

33、liquid ingress.Ensure the paper is in contact with the back and palm of the hand insidethe glove.BRITISH STANDARD BS 7971-6:2016 The British Standards Institution 2016 3e) Prepare a minimum of 50 ml of each of the following test liquids:1) 50% ISO-octane/50% toluene (petrol substitute);2) Methyl Iso

34、butyl Ketone (AR grade);3) 50% ethanol/50% water;4) 30% aqueous sulfuric acid; and5) 40% aqueous sodium hydroxide.f) Place the glove onto a horizontal arm of a retort stand placed above ametal tray of a sufficient size to allow residual liquid to drain from theglove during application.g) Pour 40 4 m

35、l of test liquid evenly across the palm and back of the glove,rotating the glove on the retort stand such that after application it ishorizontal with the palm facing down and any spilled volume left in thetray.NOTE 1 It has been found that using smaller containers each holding 20 2 mlof the test liq

36、uid, one per palm and back, makes application more consistent.h) Leave the samples for a period of 10 min 30 s prior to removal from theretort stand and assess any initial damage.i) Remove the absorbent paper from inside the glove and, if any liquidpenetration is visible as damp patches, note the lo

37、cation of ingress andmake a comment on severity of ingress (none/slight/moderate/severe).j) 1h2minafter pouring the chemical, carry out a visual inspection of theglove, comparing it to an original (or photographs) and note any damage orvisual change (for example, surface marking or damage, damage to

38、 stitchingor seams, lack of functionality).NOTE 2 The test sample should be cut open to assess any internal damage.4.4.3 Ergonomic performance4.4.3.1 GeneralTest subjects shall evaluate the position on the hands before, during and aftercompletion of a number of basic activities, also assessing the e

39、ase of performingthe activities, and discomfort of the gloves.At least one size of the glove shall be evaluated by two test subjects.Gloves shall be worn over a long-sleeved undergarment but without anyadditional clothing being worn on top of the glove.NOTE 1 For example, flame retardant base layers

40、, or alternatively a long-sleevedT-shirt.The manufacturer shall provide sizing information.NOTE 2 The ergonomic activities in this British Standard are designed to replicate arange of basic movements and tasks and eliminate fundamentally inadequate itemsfrom use. They are not designed to simulate in

41、-use conditions and are notperformed in conjunction with the specific associated PPE intended to be worn inservice by the user. It is recommended that a full ergonomic assessment with otherPPE or clothing items to be worn in conjunction with the blunt trauma protectorsshould be conducted by the spec

42、ifiers/users. See Annex A for rationale.4.4.3.2 Evaluation methodSelect a suitably sized glove using the manufacturers provided instructions.Fit and adjust the glove in accordance with the manufacturers instructions.BRITISH STANDARDBS 7971-6:20164 The British Standards Institution 2016Assessment sha

43、ll be undertaken using the following activities performed once inan order as determined by the test facility.a) Make a clenched fist.b) Make a splayed hand.c) Open and close the front zip of a garment.NOTE 1 Puller of zip should be a nominal 25 mm long.d) Remove a pen from a chest pocket and write y

44、our name.e) Lock and unlock handcuffs using a standard manufacturers key as issuedwith the handcuffs.NOTE 2 An example handcuff key is shown in Annex B.f) After1hofwearing, doff and don the gloves five times.The test subject shall answer all the following questions:1) Is the supplied information sui

45、table to enable selection of an appropriatelysized glove?2) Were clear instructions given to enable correct fitting and adjustment?3) Was it possible to complete the activities without restriction?4) Did the glove remain in place?5) Was any level of discomfort experienced?6) Did any fastenings fail?

46、7) On repeated doffing and donning of the gloves did the lining stay correctlyin place within the glove?4.4.3.3 Test reportThe test report shall include the following information:a) sample details and description;b) size/s evaluated; andc) the findings of the test subjects and assessor in response t
