In the case
45、of double-channel gaskets, place the test pieces between the pressure plate 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 p
46、ressure that would be encountered during application.A.2 ApparatusA.2.1 The 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
47、 applied force with an accuracy of 2 % of the full-scale reading.A.2.2 The 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 sub
48、ject to actual use conditions.A.2.3 The pressure plate and support frames 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 pieceA.3.1 The extruded test pieces shall be at least 50 mm long
49、 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 ProcedureA.4.1 Place the test pieces in the support frames as shown in Figures A.1 or A.2. The clearance at this time shall be the subject of agreement between the interested parties. The test shall be conducted at a standard laboratory temperature.A.4.2 Strain the pressure plate at a straining speed of 10 mm/min un
