8、9 MDTNo reproduction or networking permitted without license from IHS -,-,- BS 8512:2008 ii BSI 2008 Foreword Publishing information This British Standard is published by BSI and came into effect on 31 March 2008. It was prepared by Subcommittee GEL/20/17, Low voltage cables, under the authority of
9、Technical Committee GEL/20, Electric cables. A list of organizations represented on this committee can be obtained on request to its secretary. Information about this document This is a new standard, which has been written to give sound guidance on how to handle cables supplied on wooden drums betwe
10、en the point of manufacture and the point of installation. The need for such guidance is most apparent when cables are packed, transported, stored and handled in the form of coils wound on to large wooden cable drums, and is primarily intended for stockists, wholesalers, distributors and contractors
11、. The purpose of this new code of practice is to offer codified information to ensure that cable reaches the point of installation in the best possible condition and can be used as part of any health and safety assessment. Use of this document As a code of practice, this British Standard takes the f
12、orm of guidance and recommendations. It should not be quoted as if it were a specification and particular care should be taken to ensure that claims of compliance are not misleading. Any user claiming compliance with this British Standard is expected to be able to justify any course of action that d
13、eviates from its recommendations. It has been assumed in the preparation of this British Standard that the execution of its provisions will be entrusted to appropriately qualified and experienced people, for whose use it has been produced. Presentational conventions The provisions in this standard a
14、re presented in roman (i.e. upright) type. Its recommendations are expressed in sentences in which the principal auxiliary verb is “should”. Commentary, explanation and general informative material is presented in smaller italic type, and does not constitute a normative element. Contractual and lega
15、l considerations This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. Copyright British Standards Institution Provided by IHS under

17、d installations, rated up to 1 900/3 300 V, that are packaged on wooden cable drums suitable for storage outdoors. NOTEThe recommendations could also be applied to: cables of higher rated voltages that are packaged on wooden drums; and cables of similar size, on similar wooden drums, and made to sta
18、ndards and specifications not specifically quoted here. This standard does not cover metal drums, cable spools or cable reels, or trailing and reeling cables. 2 Normative references The following referenced documents are indispensable for the application of this document.

32、ctive clothing. NOTEAttention is drawn to the Management of Health and Safety at Work Regulations 1992 2. 4.2 Loose clothing should be avoided. 4.3 Gloves with stapled palms should not be used. 4.4 Gloves used should be designed to protect the wearer from sleeve cuffs being caught in a rolling drum.
33、 5 Storage 5.1 Cables stored at temperatures which are below those recommended for installation by cable guides to use in relevant product standards, or cable manufacturers should not be subjected to any mechanical stress, i.e. shocks, impact, bending and torsion. 5.2 Cable drums should be stored on
34、 a flat, firm, even and well-drained surface, in an upright position, using wedges in the heels of the flanges (see Figure 1a). They should not be stored on their side (see Figure 1b) or stacked, i.e. flange on flange. 5.3 Cable drums should be stored so that the drum flanges do not touch cable on a
35、nother drum (see Figure 1c). 5.4 Drums of cable that have been supplied with battens already applied should be left in place. Drums that have been supplied without battens, or drums where battens have been removed, should be assessed as to the likelihood of damage to the cable, taking into account t
36、he storage facility or method of transport, and have battens fitted or re-fitted if considered appropriate. 5.5 To protect against UV degradation, all cables in long-term storage should be shielded from direct sunlight or other UV sources by suitable coverings such as black plastic sheeting. 5.6 A r
37、egular system of inspection and action should be followed, paying particular attention to drums that have been stored for long periods. If a drum has deteriorated or been damaged, the cable should be rewound onto a replacement drum, and the cable inspected for damage. Work Regulations 1999 1 and the

41、g of drums. NOTEAttention is drawn to the Manual Handling Regulations 1992 3, as amended in 2002, which apply to a wide range of manual handling activities including lifting, lowering, pushing, pulling and carrying. 6.2 Cable drums should be rolled only for short distances over flat, solid ground in
42、 the direction indicated by the arrow on the flange (see Figure 2), having regard to: the mass of the drum; the method and direction of rolling; the condition of floor/ground including slopes; the risk assessment. Particular care should be taken when drums are full of cable. 7 Lifting 7.1 Only fork-
43、lift trucks or cranes of sufficient size and weight limit for the drums to be lifted should be used. 7.2 When lifting drums by crane, a spreader beam should be used (see Figure 3). The spreader beam should be of the weight capacity and length specified by the manufacturer for the weight and width of
44、 drum. Any slings or hooks should be of the correct weight capacity, as specified by the manufacturer, for the drum to be lifted. 7.3 When lifting drums by fork lift trucks, the cable drum flanges should be at right angles to the forks, and the forks should be longer than the width of the drum (see
45、Figure 4). NOTESpecially adapted fork lift trucks may use spindle type lifting bars, booms or fork shoes or extensions, for which advice can be sought from the truck supplier. Figure 2Handling drums NOTEWooden drums frequently have an arrow marked on their flanges to indicate both the direction that
46、 cable is to be wound on to them and also the direction in which the drum is to be rolled.
