The SSPC Surface Profile Committee has been preparing a specification for the measurement of surface profile based on the four methods described in ASTM D4417, Standard Test Methods For Field Measurement Of Surface Profile of Blast Cleaned Steel. These methods are surface comparators, surface profile depth gauges, replica tape and the stylus profile gauges.

The work has included a pilot study of the three methods that produce readings, the surface profile depth gauges, the replica tape with the dial gauge and the stylus method gauges, undertaken by ASTM subcommittee D01.46.

This paper describes the use of the four methods and the way in which the equipment for the four methods can be verified before they are used.
