This document specifies a method for the determination of the apparent volatile-matter content in pre-impregnated yarns, tapes, mats (SMC) and fabrics.
The method is applicable to all unidirectional and multidirectional fibre-reinforced prepregs and all thermosetting-resin matrices, unless otherwise specified in product specifications.
The method does not apply to unimpregnated reinforcement fibres.
NOTE For products with a polyester-resin matrix (UP), the result will be lower than the real value.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
