Annex C is informative and provides some detailed information for use and maintenance which may be appropriate in hs the information in accordance with annex B. Lifting operations not covered be 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.
NOTE Items b to h inclusive form the designation of the roundsling or roundsling assembly. This is indicated by the fibres of the cover material taking on a glazed appearance and in extreme cases, fusion of the fibres can occur, indicating a weakening of the core.
A British Standard does not purport to include all the necessaiy provisions of a contract. The specimen shall be subjected to a force equivalent to not less than 7 times the WLL of the roundsling. Verification of the force measuring system of the tensile testing machines. They are extremely light weight and bx in multiple directions, allowing easy and quick manipulation even when fragile loads are being lifted.
Keep labels away from hooks and fittings. The roundsling ej not be pre- loaded prior to testing, unless all roundslings of the same type are subjected to identical pre-loading. Damaged slings should be withdrawn from service.
BS EN 1492-2:2000+A1:2008
Store roundslings by hanging on non-rusting pegs which allow the free circulation of air. This is especially important with basket or other loose hitches where friction retains the load.
Slings with grade 8 fittings and multi-leg master links should not be used in acidic conditions. The content of the constituent materials may be determined in accordance with ISO Further, ice will lessen the flexibility of the sling, in extreme cases rendering it unserviceable for use. Chemical attack results in local weakening and softening of the material.
Annex B is normative and gives the requirements for information on use and maintenance to be provided by the manufacturer with roundslings conforming to enn European Standard.

Elingues rondes, en textiles chimiques, d’usage courant Textile Anschlagmittel – Sicherheit – Teil 2: Specification for lifting slings for general service made from natural and man-made fibre rope. The material from which the roundsling is made should not be affected adversely by the environment or the 14922. Any additional joins in the yarns shall be separated by at least four turns of the bz and shall be compensated for by an extra turn per join see Figure 1.
Material — polyester, identified by a blue label, is resistant to moderate strength acids but is damaged by alkalis; polyamide Nylon identified by a green label, is virtually immune to alkalis but is damaged by acids; polypropylene, identified by a brown label, is little affected by acids or alkalis but is damaged by some solvents, tars and paints and therefore suitable for appliances where the highest resistance to chemicals other than solvents is required.
NOTE The cover of a roundsling may rupture prior to the core, therefore during this test the roundsling is deemed to fail when the core fails to sustain the load. Additional information In the UK, the Lifting Operations and Lifting Equipment Regulations LOLER require that accessories for lifting are thoroughly examined by a competent person at either 6 month intervals, or in accordance with a scheme of examination drawn up by a competent person.
Consideration should also be given to ancillary fittings and lifting devices which should be compatible with the sling s.
Do not alter, modify or repair a roundsling but refer such matters to a Competent Person. If the cover is welded, care shall be taken to ensure that the welding does not affect the core. EN ; i test references see clause 6 ; j traceability code; k identity of the person authorized to sign the certificate on behalf of the manufacturer and date of signature.

Information on standards BSI provides a wide range of information on national, European and international standards through its Library and its Technical Help to Exporters Service. In an emergency cordon off the area. Sling s should be arranged so that the point of lift is directly above the centre of gravity and the load is balanced and stable.
In normal use, some chafing will occur to the surface fibres of the cover. 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.

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.
Take the smart route to manage medical device compliance. Apply the mode factor for the slinging eh. It shall be uniformly wound to ensure even distribution of the load. If more than one sling is used to lift a load, these slings should be identical.
