ASTM D4018-99
Historical Standard: ASTM D4018-99 Standard Test Methods for Properties of Continuous Filament Carbon and Graphite Fiber Tows
SUPERSEDED (see Active link, below)
ASTM D4018
1. Scope
1.1 These test methods cover the preparation and tensile testing of resin-impregnated and cured test specimens made from continuous filament carbon and graphite yarns, rovings, and tows to determine their tensile properties.
1.2 These test methods also cover the determination of the density and mass per unit length of the yarn, roving, or tow to provide supplementary data for tensile property calculation.
1.3 These test methods include a procedure for sizing removal to provide the preferred desized fiber samples for density measurement. This procedure may also be used to determine the weight percent sizing.
1.4 These test methods include a procedure for determining the weight percent moisture adsorption of carbon or graphite fiber.
1.5 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.
1.6 This standard does not purport to address all of the safety problems, 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.
