Includes, in separate sections, general requirements for all specimens, specific requirements for turned, ground, bored, milled, shaped or planed specimens, specific requirements for spark-eroded, shot-blasted, grit-blasted or polished specimens, and specific requirements for cast surfaces. R(sub)a(/sub) values are given for all surfaces together with accuracy requirements, and an appendix illustrates typical sets of mounted roughness comparison specimens.

This standard specifies the characteristics of surface roughness comparison specimens intended for tactile and visual comparison with workpiece surfaces produced by similar processes. Roughness comparison specimens for the following processes are given:(a) Turned, ground, bored, milled, shaped or planed specimens: (Section 2).(b) Spark-eroded, shot blasted, grit blasted, or polished specimens: (Section 3).(c) Specimens for cast surfaces: (Section 4). (d) Calibration of surface roughness specimens: (Section 5).The standard also includes definitions used in surface roughness and gives information on cut-off lengths and marking requirements. Appendices give information on typical sets of mounted roughness comparison specimens, the use of roughness comparison specimens, roughness grade numbers and roughness average values of Ra (arithmetic mean deviation) in both metric and the corresponding imperial units.
