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, reference should be made to the specification for that product.

1.2 The test methods appear in the following sections of this standard:

Procedure Sections Dimensional measurements of insulations, jackets, miscellaneous cable components, and of completed cable 4-9 Cross-sectional areas 9 Diameters 6 Eccentricity 8 Thickness 7 Physical 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 13 Physical and environmental tests of insulations and jackets of completed wire and cable 26-40 Cable Torsion Test 37 Compound flow test (filled core wire and cable only) 40 Corrugation extensibility test 35 Cable impact test 33 Jacket bonding tests 29 Jacket notch test 32 Jacket peel or pull 28 Jacket slip strength test 30 Pressure test (air core wire and cable only) 38 Sheath adherence test 31 Water penetration test (filled core wire and cable only) 39 Wire and cable bending test 34 Wire breaking strength 36

1.3 The values stated in inch-pound units are to be regarded as the 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 and health practices and determine the applicability of regulatory limitations prior to use .
