Measurement of Maximum Arrest Force in Performance Tests of Fall Protection Equipment
Frequency response characteristics for electronic measurement systems and mechanical test fixtures used in tests of fall protection equipment are proposed. The recommendations are based upon the analysis of the dynamic properties of the human body as measured in impact and vibration tests with volunteer subjects. The critical frequencies that are associated with human injury were found to be in the range of 0 to 16 Hz. A corner frequency of 100 Hz is recommended for the measurement system, and a minimum resonant frequency of 200 Hz is recommended for the mechanical test fixture.
