BS EN 1492-2:2000+A1:2008EN 1492-2:2000+A1:2008 (E)4 Introduction This European Standard has been prepared to be a harmonized standard provid
28、ing one means of complying with the essential safety requirements of the MachineryDirective and associated EFTA regulations. This European Standard is a type C standard as specified in EN 292. The lifting accessories concerned and the extent to which hazards are covered is indicated in the scope of
29、this standard. NOTE For hazards that are not covered by thisstandard, lifting accessories should be in accordance with EN 292. 1 Scope This European Standard specifies the requirements related to safety, including methods of rating and testing roundslings up to 40 tonnes working load limit (in strai
30、ght lift) and two-, three-, and four-leg roundsling assemblies,with orwithout fittings, made of polyamide, polyester and polypropylene. The roundslings covered bythis Part of EN 1492 are intended for general purpose lifting operations, i.e. when used for lifting objects, materialsor goods which requ
31、ire no deviations from the requirements, safety factors or WLLs specified. Lifting operations not covered by this standard include the lifting of persons, potentially dangerous materials such as molten metal and acids, glass sheets, fissile materials, nuclear reactors and where special conditions ap
32、ply.Roundslings conforming to this European Standard are suitable for use and storage in the following temperature ranges: a) polyester and polyamide:-40C to 100C, b) polypropylene: -40C to 80CThis European Standard does not applyto the types of roundsling indicated below:a) roundslings designed for
33、 securing or lashing of cargoes to each other on pallets and platforms or in vehicles;b) slings oftubular webbing withoutfilling.This European Standard deals with the technical requirements to minimize the hazards listed in clause 4 which can arise during the use of roundslings when carried out in a
34、ccordance with the instructions and specifications given by the manufacturer or authorized representative. 2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in th
35、e text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of anyof these publications applyto this European standard only when incorporated in it by amendment or revision.

43、nually examined, appears closed, as is the case following thermofixing or colouring with additional substances, and where the single fibres support each other.BS EN 1492-2:2000+A1:2008EN 1492-2:2000+A1:2008 (E)6 3.7 fitting loadbearing metal component, supplied as part of a roundsling so as to allow
44、 it to be attached to other lifting accessories, connected to other roundslings to form a multi-leg sling assembly or connected to the hook of a crane or other lifting machine. 3.8 master link link, or link assembly, forming the upper terminal fitting of a multi-leg sling assembly by means of which
45、the sling assembly is attached to the hook of a crane, other lifting machine orlifting accessory. 3.9 nominal length specified length of the roundsling, inclusive of fittings, from bearing point to bearing point (See 5.5)3.10 effective working length (EWL) actual finished length of the roundsling, i
46、nclusive of fittings, from bearing point to bearing point (See 5.5)3.11 working load limit (WLL) maximummass which a roundsling is designed to sustain in straight lift and which a sling or sling assemblyis authorized to sustain in general lifting service (See table 2)3.12 mode factor (M) factor appl

48、ed tests and examination to be carried out. NOTE 4.18 of EN ISO 9002:1994 gives guidance on training. 4 Hazards The accidental release of a load, or release of a loaddue to failure of a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zon
49、e. In order to provide the necessary strength and durability of lifting accessories this Part of EN 1492 specifies requirements for the design, manufacture and testing to ensure the specified levelsof performance are met. Endurance has not been identified as a hazard when roundslings having the specified levels of performance given in thisPartof EN 1492 are used in generallifting service. Since failure can be caused by the incorrect choice of WLL and specification of lifting accessorythis Part of EN 1492 also gives the requirements for
