I MIL-STD-1312B Downloaded from https://www.everyspec.com NOTE 4: This indicates the msgnitude of any start-up load transients which may have effects on the fatigue life of specimens tested in the machine. g. Repeat step f for each condition of maximum output level and frequency. 80.4 Note that changes in the ambient temperature of the room in which the verification is being carried out will adversely affect the precision of the measurements. The room temperature shall not change more than .5°F (2.8“C) during the verification. 90. REPORT. 8Q.i The report shall contain the following: Description of equipment: 1.
Serial numbers and names of the manufacturers of all equipment used, including the fatigue-testingmachine, the static-testingmachine, the transducer, and each item of associated transducer instrumentation. 2. The information contained in the verification certif- icate for the static testing machine. 3. Complete, detailed description of the dynamornet er. b. For the static dynamometer calibration: 1. Method of mounting the dynamometer in machine. the testing 2. Complete record of the load and strain in the dynamometer calibration test and date performed. 3. Strain transducer excitation including chopper or carrier frequency, if applicable. c. For each dynamic verification test condition: 1.
Strain transducer excitation including chopper or carrier frequency, if applicable. 2. The load and the frequency settings. 3. The ahape of the waveform. 4. Load and strain readings from the dynamometer readout equipment. 17 c
