7、ummary of Test Method4.1 Plastisols or organosols are weighed in aluminum dishesand heated in a circulating air oven at 177C (350F) for 10min. The specimens are removed from the oven, cooled, andreweighed. The weight loss is determined and reported aseither percent weight loss or weight loss per uni
