17、2 Foreword This European Standard has been prepared by Technical Committee CEN/TC 162 “Protective clothing including hand and arm protection and lifejackets“ the secretariat of which is held by DIN. The European Standards for “Protective clothing for users of hand held chainsaws“ are the following:
18、EN 381-1 EN 381-2 EN 381-3 EN 3814 EN 381 -5 EN 381 -7 EN 381 -8 EN 381 -9. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2000, and conflicting national standards shall be withdrawn at t
19、he latest by January 2000. Protective clothing for users of hand held chainsaws - Part 1 : Test rig for testing resistance to cutting by a chainsaw . - Part 2: Test rig for leg protection . - Part 3: Test methods for footwear . - Part 4: Test method for chainsaw protective gloves . - Part 5: Require
20、ments for leg protectors . - Part 7: Requirements for chainsaw protective gloves . - Part 8: Test methods for chainsaw protective gaiters - Part 9: Requirements for chainsaw protective gaiters This European Standard has been prepared under a mandate given to CEN by the European Commission and the Eu
21、ropean Free Trade Association and supports essential requirements of EU Directive 89/686/EEC. For relationship with EU Directive), see informative Annex ZA, which is an integral part of this standard.

23、5738 158 m Page 3 EN 381 -711 999 Irrtroduction This European Standard forms pari of a series concerned with personal protective equipment designed to protect against the risks arising from the use of hand-held chainsaws. As far as is known all chainsaws are designed for right handed use and therefo
24、re all protective clothing designs and requirements have assumed right handed use. Protection can not be adequate for left handed use. No protective equipment can ensure 100% protection against cutting by a hand-held chainsaw. Nevertheless, experience has shown that it is possible to design protecti
25、ve equipment which offers a certain degree of protection. Different functional principles can be applied in order to give protection. These include: -chain slipping: on contact the chain does not cul the material; -clogging: fibres are drawn with the chain into the drive sprocket and block chain mov
26、ement; - 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. This European Standard specifies the requirements for gloves for resistance to cutting by a chainsaw when assessed by the test me
27、thod described in EN 381-4. The requirements are also given for marking and for the provision of information to be supplied by the manufacturer including criteria for the selection of appropriate gloves, and instructions for use. 2 Normativereferences This European Standard incorporates, by dated or
28、 undated reference, provisions 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
29、when incorporated in it by amendments or revision. For undated references the latest edition of the publication referred to applies.

This protective material may include the cloth of the garment. 3.8 protective c
34、overage the area of the glove which is covered by protective material. 3.9 specified protective area the required protective coverage. 4 Deslgns 4.1 Designs of gloves This standard defines two designs of chainsaw protective gloves, design A and design B. Design A and design B have different specifie
35、d protective areas as defined in 4.2 and 4.3. 4.2 DesignA 4.2.1 Description of design A Design A applies to fivefinger gloves without chainsaw protection in the fingers or thumb. 4.2.2 Specified protective area for design A - Left hand gloves The specified protective area is shown in figure 1. It is
36、 the back of the metacarpus. The minimum length of the protective material across the minimum required width of protective material in size 9 gloves shall be 120 mm. The distal edge of the protective material shall be not more than 8 mm from the crotches between digits 2 and 3,3 and 4, or 4 and 5. T
37、he minimum width of the protective material throughout a length equal to the minimum required length of protective material for size 9 gloves shall be a 110 mm. The minimum lengths and widths of protective material in other sizes of gloves shall be calculated from the hand lengths and widths in tabl
38、e 1 of EN 420:1994. The dimensions shall be measured on one glove from each pre-treatment in accordance with clause 6 of EN 381 41 999. 4.23 Protective coverage for design A - Right hand gloves No protective coverage is required. If protection is offered, however, then it shall at least equal that s
