Common use of Recording instruments Clause in Contracts

Recording instruments. The recording instruments used shall be such that measurements can be made with the following degrees of accuracy: 1.3.1. Acceleration: accuracy = + 5 % of the actual value; frequency class of data channel: class 600 corresponding to ISO Standard 6487 (1980); cross‑axis sensitivity = < 5 % of the lowest point on the scale. 1.3.2. Speed: accuracy: + 2.5 % of the actual value; sensitivity: 0.5 km/h. 1.3.3. Time recording: the instrumentation shall enable the action to be recorded throughout its duration and readings to be made to within one one‑thousandth of a second; the beginning of the impact at the moment of first contact between the headform and the item being tested shall be detected on the recordings used for analysing the test.
