1.1 ,This guide covers the flexural testing of beams and girders under simulated service conditions to determine their structural performance characteristics. Methods following this guide are intended primarily for constructions that may not conform with the relatively simple assumptions upon which well-known flexural theories are based. In some cases, they are also suitable for determining the structural adequacy of the design, materials, connections, and fabrication techniques. The methods are not intended for use in routine quality control tests.
