It shall be used together with EN 2591. 2 Normative re

The following details shall be specified in
9、the technical specification : - number of specimens; - type of cable; - - voltage strength. installation and wiring of specimens; Terminal lugs To facilitate the test, the spade end may be cut flush with the insulator and this end is insulated by covering with beeswax or some other watertight materi
10、al, making sure that this covering does not cover the area of the barrel deformed by the crimping tool. In-line splices The shortest cable shall be cut flush with the insulator of the in-line splice. This end shall be insulated by coating in the same way as outlined above. 4 Method The crimped compo
11、nent shall be immersed in an aqueous solution containing 5% sodium chloride to a depth that allows the crimped area to be covered. Apply a voltage between the specimen and an immersed electrode situated a maximum of 50 mm from the specimen. This voltage shall be increased gradually, without exceeding 500 V/s, to 1 500 V, 50 Hz or to the voltage strength specified in the technical specification ; it is then kept at this value for a minimum of 60 s. 5 Requirement There shall be no burn-out of the insulation.
