First Company To Be Awarded BS EN 50393
Birkett Electric were the first manufacturer to successfully test to Harmonisation Draft HD623 and the subsequent BS EN 50393.
- BS EN 50393 is the culmination of over 10 years work to integrate European cable jointing standards. In effect it is a testing framework for agreement between the manufacturer and the client to demonstrate compliance for the full range of underground cable joints on a supply contract
- Resin, connectors and earth continuity assembly comes under scrutiny with a total of nine straight, branch and multi-service joints to be tested. The manufacturer can reduce this to three cable joints by offering to test three straight-cum-tee mains branch joints
- By specifying and purchasing Birkett cable jointing kits, all concerned, be they the consultant, public utility, local authority, street lighting contractor or the electrical buyer are all protected knowing that a cable joint certified under strict test conditions by a leading test house has been produced and installed
- All national standards conflicting with this European EN were withdrawn 1st October 2008
- Test report number issued by ERA Technology Limited: 20060659, 20060660 and 20060661
