AS B131-1962

The grading of surface texture is dependent of geometrical measurement and the principles laid down may, therefore, be applied to surfaces other than machined surfaces. This Standard relates to: the terminology to be employed in statements relating to surface texture; preferred values for the grading of surface texture (centre-line-average values); standard instrument cut-off values to be used in graphical procedure and instrument construction; the graphical determination of CLA values; the instruments and methods to be employed in the quantitative assessment of surface texture; and the information to be given in statements relating to surface texture. General information on the assessment of surface texture is given in the Appendix.
