IS 10579 : 1983 Specification for Polyethylene (PE) sulation and Sheath of Telecommunication Cables

1 Scope

1.1 This standard specifies physical and electrical requirementsand test methods for various types of polyethylene (PE) insulationand sheath of telecommunication cables taken, where possible, fromthe cables after manufacture.

Note 1 - The types of PE compounds recognised for the purposeall contain antioxidants.

Note 2 - PE co-polymers have not yet been included in thisstandard. It is intended to include them when sufficient data isavailable.

Note 3 - Unless otherwise specified in the relevant cablespecifications, sheath compounds shall also contain carbon black ofsuitable type uniformly dispersed throughout the material.

1.2 This standard does not deal with cross-linked or cellularmaterials and materials for special applications, for example,coaxial cables for submarine, CATV, RF or other applications.
