【国外标准】 Standard Test Methods for Physical and Environmental Performance Properties of Insulations and Jackets for Telecommunications Wire and Cable

5.1 Dimensional measurements, properly interpreted, provide information with regard to the conductors, insulation, or jacket. The dimensional measurements provide data for research and development, engineering design, quality control, and acceptance or rejection under specifications.1.1 These test methods cover procedures for the physical testing of thermoplastic insulations and jackets used on telecommunications wire and cable and the testing of physical characteristics and environmental performance properties of completed products. To determine the procedure to be used on the particular insulation or jacket or on the completed wire or cable, make reference to the specification for that product.1.2 These test methods appear in the following sections of this standard:Test Method Section(s)Dimensional Measurements of Insulations, Jackets, Miscellaneous   Cable Components, and of Completed Cable 4 – 9     Cross-sectional Areas 9     Diameters 6     Eccentricity 8     Thickness 7Physical and Environmental Tests of Insulation and Jackets 10 – 25     Aging Test (Jackets Only) 24     Cold Bend (Insulation Only) 16     Environmental Stress Crack (Polyolefin Jackets Only) 21     Heat Distortion (Jackets Only) 22     Heat Shock (Jackets Only) 23     Insulation Adhesion 19     Insulation and Jacket Shrinkback (Oven Test) 14     Insulation Compression 20     Insulation Shrinkback (Solder Test) 15     Melt Flow Rate Change—Polyolefin Materials 12     Oil Immersion Test (Jackets Only) 25     Oxygen Induction Time (Polyolefin Insulation Only) 17     Oxygen Induction Time (Cable Filling Compound Only) 18     Tensile and Elongation Tests 13Physical and Environmental Tests of Insulations and Jackets of   Completed Wire and Cable 26 – 42     Cable Torsion Test 38     Compound Flow Test (Filled Core Wire and Cable Only) 42     Corrugation Extensibility Test 36     Cable Impact Test 33     Jacket Bonding Tests 29     Jacket Notch Test 32     Jacket Peel or Pull 28     Jacket Slip Strength Test 30Procedure Section(s)     Pressure Test (Air Core Wire and Cable Only) 40     Sheath Adherence Test 31     Water Penetration Test (Filled Core Wire and Cable Only) 41     Wire and Cable Bending Test 34     Wire breaking strength 371.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard, except where only SI units are given.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific warning statement see 19.1.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
