26、ropean Standard forms part of a series concerned with personal protective equipment designed to protect against the risks arising from the use of chain saws. No personal protective equipment can ensure 100 % protection against cutting by a chain saw. Nevertheless, experience has shown that it is pos
27、sible 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) clogging: fibres are drawn by the chain into the
28、 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 specifies requirements to be used to assess the resistance of
29、gaiters to cutting by hand-held chain saws and other properties. A requirement for the strength of underfoot straps of gaiters is also included. This European Standard is applicable to gaiters used together with safety footwear according to EN 345 : 1992 and EN 345 : 1992/A1 with a metallic toecap,
30、because gaiters offer only partial protection against chain saw cutting. Gaiters according to this European Standard are not intended for use in situations where there is a significant risk of tripping such as tree climbing or in forests. The test methods associated with the requirements in this Eur
31、opean Standard are given in EN 381-8. 2 Normative references This European Standard incorporates, by dated or 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 referen
32、ces, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendments or revision. For undated references the latest edition of the publication referred to applies. EN 345:1992, EN 345:1992/A1 Specification for safety footw
33、ear for professional use EN 381-8:1997 Protective clothing for users of hand-held chain saws Part 8: Test method for chain saw protective gaiters 3 Definitions For the purposes of this European Standard the following definitions apply. 3.1 foot protector Any product which protects the foot and the l
34、ower part of the leg (or any part of this area) against cutting by a handheld chain saw. 3.2 gaiter A removable covering intended to protect the front part of the foot, ankle and lower leg against cutting by a hand-held chain saw EN 381-8. 3.3 protective material Material which is designed to resist
35、 the cutting effect of a handheld chain saw. 3.4 protective coverage The area of the gaiter which is covered by protective material. 4 Requirements 4.1 Fasteners 4.1.1 General Gaiter fasteners shall not be of touch and close type. 4.1.2 Underfoot straps When tested in accordance with the procedure d
36、escribed in clause 6 of EN 381-8 : 1997 each underfoot strap shall not fail at a force below 250 N. When tested in accordance with the procedure described in clause 6 of EN 381-8 : 1997 the distance moved by the hook between loads of 25 N and 250 N shall be less than 50 mm. 4.2 Specified protective
37、area The protective coverage of the gaiter shall at least cover the area of the artificial boots (see 5.3.2.1 of EN 381-8 : 1997) shown in figure 1, i.e.: a) horizontally from a line no more than 14 mm behind the end of the artificial boot, to two lines in the same vertical plane sited at least 80 m
38、m either side of the centre line of the front of the boot, measured at a height of (225 2) mm above the lower surface of the artificial boot; b) vertically from the line no more than 25 mm above the lower surface of the artificial boot to at least 200 mm above this line. 4.3 Classification according
39、 to chain speed The classification shall be made with the following 4 speeds: Class of protection 0 : 16 m/s NOTE. Class of protection 0 is valid until 1999-12-31 Class of protection 1 : 20 m/s Class of protection 2 : 24 m/s Class of protection 3 : 28 m/s 4.4 Requirements to cut resistance When test
40、ed according to clause 5.4 of EN 381-8 : 1997 no cut through is allowed in the leather covering the boot form under any tested specimen.Page 4 EN 381-9 : 1997 BSI 1997 5 Marking Gaiters for users of chain saws shall be durably marked with at least the following: name or trade mark or other means of
41、identification of the manufacturer and/or his authorized representative; type identification or style No. (company identification of model); serial number/batch number; date of manufacture (year and month); the number of this European Standard: EN 381-9; size designation of the combinable safety foo
42、twear; speed classification. This information shall be given outside the frame of the pictogram showing a chain saw, preferably on the bottom of the frame; the sentence If the protective material is damaged, the gaiter is to be discarded, or similar; washing/cleaning instructions including warnings
43、against incorrect treatment; the text Only to be worn in conjunction with safety footwear conforming to EN 345 : 1992 and EN 345 : 1992/A1. 6 Information supplied by the manufacturer Gaiters for users of chain saws shall be supplied with an unambiguous information for the user, in the language(s) of
44、 the country of purchase. The information for the user shall at least contain the following: the information given in the marking; name, address and telephone number of manufacturer and/or his authorized representative; instructions about repair of the gaiter especially pointing out that it is not a
45、llowed to repair the protective material; instruction that the protective area and material shall not be altered in any way and that once cut into, the gaiter should be discarded; a warning that the gaiters are not intended for use in situations where there is a significant risk of tripping such as
46、tree climbing or in forests; criteria for discarding the gaiter; instructions for correct fastening; instructions on the protective coverage, i.e. a figure with size designation (or a statement of the range of footwear sizes with which the gaiter may be worn) plus advice as to the area the gaiter sh
47、ould cover. This should include the information that gaiters should always: a) overlap the toe cap of the wearer boots by at least 30 mm; b) not overlap the boot sole to such an extent that it causes a trip hazard; c) not leave an unprotected space between the edge of the gaiter and the sole. the te
48、xt Does not protect against all risks or similar. 7 Pictogram Gaiters complying with this European Standard shall be marked with the pictogram shown in figure 2. The pictogram shall be placed at any visible place on each gaiter and have a minimum size 30 mm3 30 mm. Dimensions in millimetres Figure 1
