1.1 This specification covers requirements for the performance characteristics including conventional mechanical tests, simulated service tests and testing equipment for determining the characteristics of homogeneous tool-resisting steel bars and does not preclude the possibility of severing or penetrating this material by cutting means other than those described herein. This material can be severed with tungsten/carbide coated or tipped saws.

1.2 Three tests, describing minimum performance characteristics required for bars of different diameters covered by this specification are: (1) drop-weight test, (2) cutting test, and (3) deflection test.

1.3 The values stated in inch-pound units are to be regarded as the standard.
