A.4Methods For UKAS accredited tests, ensure two replicate samples are prepared and the fabric is conditioned for 24 hours prior to the test at 20 C 2 C and 65% 2% RH. Into a 22 ml reaction vessel weigh 0.500 0.005 g diced fabric using a four-figu

Wrap PTFE tape around the threads of the bottle and screw cap on securely. Heat the water in the ultrasonic bath. Check the temperature and w
36、hen it is 75 C 2 C place the reaction tubes in the bath. Switch on the ultrasonic generator and sonicate for 15 min against a calibrated stopwatch. At the end of this time transfer the vials to a cold water bath for rapid cooling. Filter the extracts through a 0.45 4 syringe filter into a screw-top
