Historical Standard: ASTM D7127-05 Standard Test Method for Measurement of Surface Roughness of Abrasive Blast Cleaned Metal Surfaces Using a Portable Stylus Instrument
SUPERSEDED (see Active link, below)
ASTM D7127
1. Scope
1.1 This test method describes a shop or field procedure for determination of four roughness characteristics of surfaces prepared for painting by abrasive blasting. The procedure uses a portable skidded or non-skidded stylus profile tracing instrument. The three measured characteristics are: Rt, Rmax, and Pc.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 In general, this method should be limited to the measurement of surface roughness where Rmax is in the range 10 to 150 m (0.4 to 6 mil) and where the Peak Count, Pc, is less than 180 peaks/cm (450 peaks/in.).
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 and health practices and determine the applicability of regulatory limitations prior to use.
