This document specifies four methods for the determination of the density of carbon fibre tested as a yarn:

  1. method A: liquid-displacement method;

  2. method B: sink/float method;

  3. method C: density-gradient column method;

  4. method D: gas pycnometer method.

Method C is the reference method in cases of dispute, etc.
