4 Principle
4.1 Wet extraction (Method A)
Determination of the difference in mass by means of weighing to constant mass before and after
extraction of the resin by acid digestion. Use a solution of concentrated sulfuric acid and hydrogen
peroxide. Nitric or other suitable acids can be used depending on the matrix that is to be dissolved.
4.2 Soxhlet extraction (Method B)
Determination of the difference in mass by means of weighing to constant mass before and after
extraction of the resin with methyl-ethyl-ketone or other suitable solvent agreed between the user and
manufacturer.
4.3 Extraction by soaking and decantation (Method C)
Similar to 4.2 but faster. In case of dispute, 4.2 shall be applied.
4.4 Information on the use of the methods
4.4.1 Method A
If the preimpregnate contains only fibre and a resin which is completely “digestible”, the resin content
is equal to the loss on wet digestion.
The fibre used as a reinforcement may be coated with a resin size, which is normally removed during
wet digestion. The

If the preimpregnate contains only fibre and a resin which is completely “digestible”, the resin content
is equal to the loss on wet digestion.
The fibre used as a reinforcement may be coated with a resin size, which is normally removed during
wet digestion. The size is therefore included in the resin content.
Where undissolved fillers are lost by filtering, they are thus included in the resin content.
NOTE There may be a partial loss of undissolved fillers, one part being counted with the resin and the rest being
counted with the fibres.
