3.2 Preheat the glass plate hearing the coating, the SI by 51-mm (2 by 2-in.) glass square. and the weights foe 30 mm at 5YC. Place the square of vinyl faiwic sat the coatrug with tare and etisrer intimate contact by rolling with the phoiograpluc roller. Cover the fabric with foil, sponge robber, glass, and weight in that order. The total weight shall be 910 g (2 b.
8. Precision and Bias
8.1 Precision—-It is not possible to specify the precision of the procedure in Test Method D2199 for measuring plasticizer migration since the test result is nonquantitalive. Repeated tests have demonstrated that several laboratories will assign the same rating to various coating fabric combinations. Also, replicate tests by one laboratory are in good agreement.
8.2 Bias—No information can be presented on the bias of the procedure in Test Method D2199 for measuring plasticizer migration since no material having an acceptable reference value is available.
9. Key words
9.1 lacquer; plasticizer migration: vinyl fabrics.
