Testing Conditions and Guidelines for Personal Fall Protection Systems

1. PERSONAL FALL ARREST SYSTEMS

(A) GENERAL TEST CONDITIONS

Lifelines, lanyards, and deceleration devices should be attached to an anchorage and connected to the body-belt or body harness in the same manner as they would be when used to protect employees, except that lanyards should be tested only when connected directly to the anchorage, and not when connected to a lifeline.
The anchorage should be rigid, and should not have a deflection greater than .04 inches (1 cm) when a force of 2,250 pounds (10.01 Kn) is applied.
The frequency response of the load measuring instrumentation should be 100 Hz.
