Load will be applied at the centre.
In all tests the load-deflection curve will be carried to or beyond the maximum load.

In one-third of the tests the load-deflection curve will be continued to 6-inch deflection, or till the specimen fails to support a 200-pound load.

Deflection readings for equal increments of load will be taken until well past the elastic limit, after which the scale beam will be kept balanced and the load read for each 0.1-inch deflection.

The load and deflection at first failure, maximum load and points of sudden change, will be shown on the curve sheet even if they do not occur at one of the regular load or deflection increments.
_Impact bending_: The impact bending tests will be on specimens of the same size as those used in static bending.

The span will be 28 inches.
The tests will be by increment drop.
