1.2 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.

These test methods cover the sampling and examination of felts and woven fabrics, saturated or impregnated but not coated with asphaltic or coal-tar materials, for use in waterproofing or for the construction of built-up roof coverings. After appropriate sampling, representative specimens shall be examined for the mass of wrapping material and mandrel (core), net mass per unit area, appearance and dimension of rolls, detached comminuted surfacing, moisture, strength, pliability, and loss on heating. Consequently, desaturated felt or fabric shall be examined for weight, retained carbonaceous matter, total comminuted surfacing, bituminous saturant, thread count of fabrics, thickness of felts, and ash content.
