Definitions to European standard EN 818-7 

For the purposes of this Part of EN 818,the following definitions apply:

 

1. nominal size:  Nominal diameter of the round section steel wire or bar from which the chain is made.

2. material diameter: Diameter of the material in the chain link as measured.

3. weld diameter: Diameter at the weld as measured.

4. length dimensionally affected by welding: Length on either side of the center of the link, affected by welding.

5. pitch: Internal length of a link as measured.

6. manufacturing proof force(MPF) of chain: Force to which during manufacture the whole of the chain is subjected.

7. breaking force( BF): Maximum force which the chain withstands during the course of a static tensile test to destruction.

8. working load limit (WLL) of chain: Maximum mass which the chain hanging vertically is authorized to sustain in general lifting service.

9. total ultimate elongation (A): Total extension at the point of fracture of the chain expressed as a percentage of the internal length of the test sample.

10. processing: Any treatment of the chain subsequent to welding, for example, heat treatment, polishing or dimension calibration.

11. lot: Specified quantity from which test sample(s) is/are selected.

12. competent person: A designated person, suitably trained qualified by knowledge and practical experience, and with the necessary instructions to enable the required examination to be carried out.

BS EN 818-7:2002+A1:2008 Short link chain for lifting purposes. Safety. Fine tolerance hoist chain, Grade T (Types T, DAT and DT)BS EN 818-7 specifies the requirements related to safety for hoist chain, Grade T (type T quenched and tempered and types DAT and DT case hardened), for use in serial chain hoists manual and power driven.

Type DAT and type DT hoist chains possess surface hardnesses greater than core hardness and are used for power driven chain hoists to offer greater resistance to wear.

Type DT hoist chain differs from DAT hoist chain in having higher surface hardness and/or greater case depth to optimise wear resistance.

BS EN 818-7 applies to electrically welded round steel short link hoist chains conforming to BS EN 818-1.

The range of nominal size of hoist chains covered by BS EN 818-7 is from 4 mm to 22 mm.
