Choose a right fixture to clamp the position where the test component is (10±2)
mm away from the top.
Apply a tension of (5±2) N at an angle of 45° to the axis of the sample. Check
the sample. Then in the same direction, at a speed of (200±5) mm/min, increase
the pulling force to (60±5) N. Maintain (10±0.5) s. Visually inspect the sample.
A in Figure 7 is the direction to apply force. When testing, the fixture shall clamp
the sample without damage. Avoid damage to the position where the sample is
