(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.

The Paradox Facing Modern Line Work

By most measurable standards, line work should be safer today than it was a generation ago. Arc-rated clothing is more comfortable and more widely worn. Insulated tools are lighter, stronger, and better maintained. Work methods are more clearly documented, and safety rules are reinforced through training and audits. Yet serious injuries and fatalities continue to occur, often during routine tasks and often involving experienced linemen. This paradox suggests that the industry has focused heavily on improving protection while paying less attention to how risk itself has evolved.
