BS EN 1492-4:2004+A1:2008EN 1492-4:2004+A1:2008 (E) 4 Introduction This European Standard has been prepared to be a harmonized standard providing one means of complying with the essential safety requirements of the
23、 Machinery Directive and associated EFTA regulations. This European Standard is a type C standard as specified in EN ISO 12100-2. The lifting accessories concerned and the extent to which hazards are covered is indicated in the scope of this standard. NOTE For hazards that are not covered by this st
24、andard, lifting accessories should be in accordance with EN ISO 12100-2. BS EN 1492-4:2004+A1:2008EN 1492-4:2004+A1:2008 (E) 5 1 Scope This European Standard specifies the requirements related to safety, including methods of rating and testing single-, two-, three-, four-leg and endless slings, with
25、 or without fittings, made of sisal, hemp and manila 3- and 4-strand laid construction natural fibre ropes and polyamide, polyester and polypropylene 3- and 4-strand laid construction and 8-strand plaited construction man-made fibre ropes having a reference number in the range of 16 to 48 inclusive.
26、 The fibre rope slings covered by this part of EN 1492 are intended for general purpose lifting operations, i.e. when used for lifting objects, materials or goods which require no deviations from the requirements, safety factors or working load limits specified. Lifting operations not covered by thi
27、s standard would include the lifting of persons, potentially dangerous materials such as molten metal and acids, glass sheets, fissile materials, nuclear reactors and where special conditions apply. Fibre rope slings conforming to this European Standard are suitable for use and storage in the follow
28、ing temperature ranges: a) polyester and polyamide -40C to 100C, b) manila, sisal, hemp and polypropylene -40C to 80C. This European Standard does not apply to fibre rope sling assemblies rated by the trigonometric method. This European Standard deals with the technical requirements to minimize the
29、hazards listed in clause 4 which can arise during the use of fibre rope slings when carried out in accordance with the instructions and specification given by the manufacturer or authorized representative. 2 Normative references This European Standard incorporates, by dated or undated reference, pro
30、visions 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
