ASTM D4417-21 - Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel
Standard Test Methods for Field Measurement of Surface Profile of Blast Cleaned Steel
|Keywords:||abrasive; abrasive blast cleaning; anchor pattern; peak count; peak density; peak height; surface profile; surface roughness;|
1.1 These test methods cover the description of techniques for measuring the profile of abrasive blast cleaned surfaces in the field, shop, and laboratory. There are other techniques suitable for laboratory use not covered by these test methods.
1.2 Method B may also be appropriate to the measurement of profile produced by using power tools.
Note 1: The Method B procedure in this standard was developed for use on flat surfaces. Depending on the radius of the surface, the results could have greater variability with lower values and averages.
1.3 SSPC standard SSPC-PA 17 provides additional guidance for determining conformance with surface profile requirements.
1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
