19、e (CRT) machine: a testing machine in which one end of the specimen is held by a clamp driven at a constant speed while the other end is gripped in a clamp attached to a weighing mechanism of a type that permits movement of the attached clamp, e.g., as in pendulum machines. The specimen is therefore

Both types of machines shall have a suitable capacity (see par. 6.3) and operate with the driven clamp moving at a speed of 300 f 10 mmimin (Note 2). 4.3 4.4 Both gripping surfaces of the clamps shall measure 25 x 50 mm or more, with the longer dimension pe

The ratchet pawls of the CRT (pendulum) type machine shall be rendered inoperative during the test. 5. 5. TEST SPECIMENS Specimens shall be cut 50 mm w
