(raised) position.

4.4.29 Calibrate IAW ASTM E23 - 2018, to include direct and indirect verifications IAW

Annex A2 of ASTM E23. Calibration/verifications required after final installation.

4.4.30 If a specimen centering device is integral to the tester, it shall not be located within 13mm of the specimen ends during testing. This requirement is to prevent broken specimens from rebounding into the pendulum. An integral specimen centering device is not a requirement.

4.5 Safety and Environmental Requirements:

4.5.1 Equipment Hazards: All hazards inside the machinery shall be guarded against unauthorized access. Clearly visible signs and symbols shall warn personnel in the area, and interlocks, safety mats and redundant deactivation systems shall guard against accidental access to the tooling and moving parts.
