1. Scope
1.1
This Standard is concerned with the geometric irregularities of surfaces of solid materials. It establishes defi nite classifications for roughness, waviness, lay, and a set of symbols for drawings, specifications, and reports, and makes reference to requirements for Tracer Type Instruments, and specificati ons for Precision Reference Standards and Texture Comparison Specimens. This Standard is not concerned with luster, appearance, colour, corrosion resistance, wear resistance, hardness, micro-structure, and many other characteristics which may be governing considerations in specifi c applications.
1.2
This Standard does not define the degrees of surface roughness and waviness or type of lay suitable for specific purposes, not does it specify the means by which any degree of such irregularities may be obtained or produced. However, criteria for selection of surface qualities and information on instrument techniques and methods of producing, controlling and inspecting surfaces are included in Appendices A, B, and C, which are not an integral part of this Standard.
1.3
Surfaces, in general, are very complex in character. This Standard deals only with the height, width, and direction of surface irregularities, since these are of practical importance in specific applications.
1.4
Terms and ratings in this Standard relate to surfaces produced by such means as machining, abrading, extruding, casting, molding, forging, rolling, coating, plating, blasting, or burnishing.
