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.
