What does ASTM D 4417 standardize?

ASTM D 4417 is specifically focused on standardizing the measurement of surface profile, particularly the height of peaks and valleys on a surface that is to be coated. This is an important aspect in coating applications because the surface profile can significantly influence coating adhesion and performance. The standard outlines specific techniques and equipment that can be used for these measurements, ensuring consistency in the way surface profiles are assessed across different projects and applications.

Measurement techniques specified by ASTM D 4417 can include the use of a depth gauge or a profilometer. By standardizing these methods, the standard allows for reliable data that can be compared and used in quality control processes, which is essential in achieving desired coating characteristics such as durability and adhesion strength.

Options related to corrosion testing methods, coating application standards, or material selection guidelines are outside the scope of ASTM D 4417, as the standard is narrowly tailored to surface profile measurement alone.
