A simple test (ASTM 3291) for evaluating the compatibility of vinyl resin plasticizers based on the fact that a material under compressive stress will exude plasticizer more rapidly. A specimen in sheet form is folded double, forming a loop with internal radius equal to the sheet thickness. At intervals, the bend of the loop is reversed 360° and the former inside surface of the loop is examined for evidence of plasticizer spewing.
