7、icated.4. Summary of Test Method4.1 Plastisols or organosols are weighed in aluminum dishes and heated in a circulating air oven at 177C (350F) for 10 min.The specimens are removed from the oven, cooled, and reweighed. The weight loss is determined and reported as either percentweight loss or weight
