1、Designation:D355407(Reapproved 2013)Standard Specification forTrack-Resistant Black Thermoplastic High-DensityPolyethylene Insulation for Wire and Cable,75 COperation1This standard is issued under the fixed designation D3554;the number immediately following the designation indicates the year oforigi
2、nal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers track-resistant black thermo-plastic high-den
3、sity polyethylene insulation.Before applica-tion to the conductor,the insulation shall comply with therequirements of Specification D1248,Type III,Class C,Category 5,Grade E10,J4,or J5.The requirements ofSpecification D1248 shall not apply to the insulation removedfrom the conductor.1.2 This type of
4、 insulation is considered suitable for use onwire or cable that will be used for continuous operation atconductor temperatures up to 75 C.1.3 This insulation is suitable for use on wire or in cableused for power transmission in overhead spaced-line service,installed at temperatures above 25 C and ex
5、posed to sunlightand other atmospheric environments between 55 and+75 C.1.4 In many instances,the insulation cannot be tested unlessit has been formed around a conductor.Therefore,tests done oninsulated wire in this standard are solely to determine therelevant property of the insulation and not to t
6、est the conductoror completed cable.1.5 Whenever two sets of values are presented,in differentunits,the values in the first set are the standard,while those inparentheses are for information only.2.Referenced Documents2.1 ASTM Standards:2D1248 Specification for Polyethylene Plastics ExtrusionMateria
