SP0287-2016-SG (formerly RP0287), “Field Measurement of Surface Profile of Abrasive Blast-Cleaned Steel Surfaces Using a Replica Tape”

Revised in 2016! This NACE International standard practice describes and characterizes one procedure for measuring the surface profile of abrasive blast cleaned steel. The measurement technique uses a tape that replicates the surface profile. Other common methods of measuring surface profile are not discussed. The standard covers the areas of equipment and procedures, provides a definition of “surface profile,” and includes an appendix that presents the results of a round-robin series of measurements illustrating the degree of accuracy of the procedure described in the standard. A second appendix statistically summarizes the data presented in the first appendix. This revision takes into account a chemical reformulation and associated modification to the manufacturer’s instructions for use of replica tape that occurred in 2010.

Key words: abrasive blast cleaned steel, ISO 8503-5, micrometer gauge, replica tape, surface profile, TG 419
