Calculation of percentage of insoluble component on clean, dry mass basis, disregarding loss of fibre mass during pre-treatment:

P 1 % = 100 rd m

where

P1%

  • is the percentage of clean, dry insoluble component,

    • m

  • is the dry mass of the test specimen after pre-treatment,

    • r

  • is the dry mass of the residue,

    • d

  • is the correction factor for loss in mass of the insoluble component in the reagent during the analysis. Suitable values for ‘d’ are given in the relevant section of each method.

    • Of course, these values for ‘d’ are the normal values applicable to chemically undegraded fibres.
