Product Testing Methods

Permissible Load

Permissible loads are tested for a maximum deflection of 1/100th of the span, with a coupling positioned at 1/5th of the span from the support. The coefficient applied to the load for coupling in the middle of the span - 0.7. Permissible load for maximum sag = L/100 on the intermediate span, coupling at 1/5th of the span.
