EN 1492-2:2000+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 Machinery Directive 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 this standard. NOTE For hazards that are not covered by this standard, 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 straight lift) and two-, three-, and four-leg roundsling assemblies, with or without fittings, made of polyamide, polyester and polypropylene. The roundslings 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 WLL’s 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 apply. Roundslings conforming to this European Standard are suitable for use and storage in the following temperature ranges: a) polyester and polyamide: -40°C to 100°C, b) polypropylene: -40°C to 80°C This European Standard does not apply to the types of roundsling indicated below: a) roundslings designed for securing or lashing of cargoes to each other on pallets and platforms or in vehicles; b) slings of tubular webbing without filling. 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 accordance with the instructions and specifications given by the manufacturer or authorized representative. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications.

3.2 multi-leg sling assembly roundsling assembly, consisting of two, three or four identical roundslings attached to a master link (See
table 2)
3.3 representative sling roundsling representative of roundslings of the same type, which is used for verification purposes (See 6.2 and 6.3) NOTE This may differ from the production roundsling in length only
3.4 core hank of yarn which comprises the loadbearing part of a roundsling.
3.5 cover woven tubular webbing, or tube made from woven fabric and joined along its length, and which encloses the core.
3.6 closed surface webbing surface (of cover) which, when visually and manually examined, appears closed, as is the case following thermofixing or colouring with additional substances, and where the single fibres support each other.
SIST EN 1492-2:2001+A1:2009
EN 1492-2:2000+A1:2008 (E) 6 3.7 fitting loadbearing metal component, supplied as part of a roundsling so as to allow 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 the sling assembly is attached to the hook of a crane, other lifting machine or lifting 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, inclusive of fittings, from bearing point to bearing point (See 5.5)
3.11 working load limit (WLL) maximum mass which a roundsling is designed to sustain in straight lift and which a sling or sling assembly is authorized to sustain in general lifting service (See table 2)
3.12 mode factor (M) factor applied to the WLL of a roundsling in order to arrive at the WLL of the roundsling or sling assembly for a given mode of assembly or use.
3.13 competent person designated person, suitably trained and qualified by knowledge and practical experience, and with the necessary instructions to enable the required 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 load due to failure of a component puts at risk, either directly or indirectly, the safety or health of those persons within the danger zone. 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 levels of performance are met. Endurance has not been identified as a hazard when roundslings having the specified levels of performance given in this Part of EN 1492 are used in general lifting service. Since failure can be caused by the incorrect choice of WLL and specification of lifting accessory this Part of EN 1492 also gives the requirements for marking and the manufacturer’s certificate. Aspects of safe use associated with good practice are given in annex B (normative) and annex C (informative). Table 1 lists those hazards in as far as they are dealt with in this standard that require action to reduce those risks identified by risk assessment as being specific and significant for roundslings made of polyamide, polyester and polypropylene.
