Test

Routing tests as specified in the relevant specification are carried out on all the drum length of cable leaving our Works. Type tests and acceptance tests as specified are also carried out on random samples as and when necessary.

Every lot of cable leaving "Caption" Works under goes the following test at the final stage of manufacturer.
