28、9 3 0 Introduction This European Standard forms part of a series concerned with personal protective equipment designed to protect against the risks arising from the use of hand-held chain saws. No personal protective equipment can ensure a100% protection against cutting from a hand-held chain saw. N

29、evertheless, experience has shown that it is possible to design personal protective equipment which offers a certain degree of protection. Different functional principles may be applied in order to give protection. These include: a) chain slipping: on contact the chain does not cut the material; b)

30、clogging: fibres are drawn by the chain into the drive sprocket and block chain movement; c) chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby reducing the chain speed. Often more than one principle is applied. 1 Scope This European Standard defines design

31、 and specifies the requirements for leg protectors which offers protection against cutting from a hand-held chain saw including the requirements for identification, marking and information for the user. 2 Normative references This European Standard incorporates by dated or undated references, provis

32、ions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by

33、 amendment or revision. For undated references the latest edition of the publication referred to applies. EN 381-2:1995, Protective clothing for users of hand-held chain saws Part 2: Test methods for leg protectors. 3 Definitions For the purposes of this standard the following definitions apply. 3.1

34、 leg protectors any type of protective garment which protects at least the specified protective area to the level of resistance specified within this standard for the leg, e.g. trousers, leggings, etc. 3.2 protective material material which is designed to protect the wearer against the cutting effec

35、t of the hand-held chain saw. This protective material may include the cloth of the garment 3.3 protective coverage the area of the garment which is covered by protective material 3.4 specified protective area the required protective coverage 4 Designs 4.1 Designs of leg protectors This standard def

36、ines three designs, designA, designB and designC for leg protectors. DesignA, designB and designC have different specified protective areas as stated in4.2, 4.3 and4.4. 4.2 Design A 4.2.1 Specified protective area for design A The specified protective area for designA is described undera),b) andc) a

37、nd is shown inFigure 1. a) Front. The specified protective area fully covers the front of the garment from50mm above the lower end of the legs to200mm above the crotch. It is allowed to leave out protective material at the fly. b) Rear, left leg. The specified protective area covers on the outer sid

38、e of the leg a50mm wide strip extending from50mm above the lower end of the leg to200mm below the crotch and then tapering to zero at a height of200mm above the crotch. c) Rear, right leg. The specified protective area covers on the inner side a50mm wide strip from50mm from the bottom of the leg to5

39、0mm below the crotch.EN381-5:1995 4 BSI 06-1999 It is allowed to extend the protective coverage, under the condition that the protection level is at least the same as in the specified protective area. There shall be no joins in the protective material within the specified protective area. 4.2.2 Othe

40、r design requirements for design A The leg protectors shall have a specified protective area as identified in4.2.1 and they shall fully enclose both the front and the rear of the users leg from50mm below the crotch to the bottom end of the garment legs. The bottom end of each garments leg shall be d

41、esigned to facilitate easy overlap of protective material with safety footwear worn by the user. 4.3 Design B 4.3.1 Specified protective area for design B The specified protective area for designB is described undera),b) andc) and is shown inFigure 2. a) Front. The specified protective area fully co

42、vers the front of the garment from50mm above the lower end of the legs to 200mm above the crotch. It is allowed to leave out protective material at the fly. Figure 1 Specified protective area, design AEN381-5:1995 BSI 06-1999 5 b) Rear, left leg. The specified protective area covers on the inner sid

43、e of the leg a50mm wide strip from50mm from the bottom to50mm below the crotch. On the outer side of the leg it covers a50mm wide strip extending from50mm above the lower end of the leg to200mm below the crotch and then tapering to zero at a height of200mm above the crotch. c) Rear, right leg. The s

44、pecified protective area covers on the inner side a50mm wide strip from50mm from the bottom of the leg to50mm below the crotch. It is allowed to extend the protective coverage, under the condition that the protection level is at least the same as in the specified protective area. There shall be no j

45、oins in the protective material within the specified protective area. 4.3.2 Other design requirements for design B The leg protectors shall have a specified protective area as identified in4.3.1 and they shall fully enclose both the front and the rear of the users leg from50mm below the crotch to th

46、e bottom end of the garment legs. The bottom end of each garments leg shall be designed to facilitate easy overlap of protective material with safety footwear worn by the user.

47、ign C The specified protective area for designC is described undera) andb) and is shown inFigure 3. a) Front. The specified protective area fully covers the front of the garment from50mm above the lower end of the legs to200mm above the crotch. It is allowed to leave out protective material at the f

48、ly. b) Rear. The specified protective area fully covers the rear of the garment from50mm above the lower end of the legs to50mm below the crotch on the inner side of each leg and to the level of the crotch on the outside of each leg. No more than two joins are allowed in the protective material. No

49、gaps shall be more than4mm wide, and shall run along the leg. 4.4.2 Other design requirements for design C The bottom end of each garments leg shall be designed to facilitate easy overlap of protective material with chain saw protective footwear worn by the user.
