This standard BS 7658-2:1993 Carbon fibre. is classified in these ICS categories:
59.100.20 Carbon materials
This International Standard specifies a method for determining the linear density (mass per unit length) of carbon fibre yarns.
When the determination of the linear density is carried out on sized fibre, a correction shall be made by calculation based on the size content (see 10.2).
The linear density determined by the method specified in this International Standard does not consider the influence of twist in the yarn.
