Posted Date:2025/9/9 1
11.4 Method 3 -VOC content and/or SVOC content, in grams per litre, of the product"ready for use" less water
Apply Formula (10) to VOC content determination.
where
VOCM3,Iw is the VOC content, in grams per litre, of the product "ready for use" less water;
fi,voc is the weight fraction of compound i in % of the test sample (see 10.2);
fw is the weight fraction of water in % of the test sample (see 8.7);
ρs is the density, in grams per millilitre, of the test sample at 23℃ (see 8.6);
ρw is the density, in grams per millilitre, of water at 23℃ (= 0,997 537 g/ml);
1 000 is a conversion factor to convert grams per millilitre in grams per litre.
