6、nke 1 Scope This test method shall be used to determine the blocking characteristics of deadener pads and similar materials used in body trim applications. 7 -. Definition Blocking is defined as the propensity of materials to stick to.one another when stacked. In order to avoid production problems,
7、the degree of blocking shall be as low as possible, so that easy separation of individual pads, even after prolonged storage, is possible. 3. 5.1 Test Pieces and Number of Test Pieces From the available material (200 f 0,5) mm x thickness OF 5 test pieces (200 f 0,51 mm x deadener pad shall be taken
