45、force test A.1 Principle This test method determines the force exerted by the gaskets to hold glass, etc. It simulates actual use conditions by applying a load to the pressure plate, which is a simulated glass. In the case of double- channel gaskets, place the test pieces between the pressure plate

46、and support frames with thickness equal to that of the articles. In the case of single-channel gaskets, attach the pressure plate and test pieces to the reglets and support frames. Thus, these measurements reflect the wind pressure that would be encountered during application. A.2 Apparatus A.2.1 Th

47、e testing machine shall be a power-driven tensile testing machine of the movable crosshead type, equipped with adjustable crosshead speed control, a suitable dynamometer, and an indicating or recording device for measuring the applied force with an accuracy of 2 % of the full-scale reading. A.2.2 Th

48、e pressure plate and support frames to be used with the testing machine shall be of a type similar to those shown in Figures A.1 and A.2. The thickness of the support frames and the groove dimensions of the reglets shall be subject to actual use conditions. A.2.3 The pressure plate and support frame

49、s shall be made of steel. The reglets shall be made of steel or a material equivalent to that of the actual reglets. Their length shall be at least 100 mm. A.3 Test piece A.3.1 The extruded test pieces shall be at least 50 mm long but no longer than the pressure plate, support frames, and reglets. A.3.2 A minimum of eight test pieces from each lot shall be tested. A.4 Procedure A.4.1 Place the test pieces in the support frames as shown in Figu
