It specifies the requirements for harmonized cross-linked elastomeric sheathing compounds. This revision brings
10、 this section of BS 7655 fully into line with BS 7655-0:1997, including amendment 1:2000, and HD 22.1 S3:1997. It also introduces type EM 9, as specified in HD 22.3 S3, amendment A1. Test methods are specified in this section of BS 7655 by reference to the latest edition of standards in which they a
11、ppear. A dated reference to the most recent edition of the relevant standard for each test method is given in BS 7655-0, which is to be read in conjunction with this section. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are res
12、ponsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.
