How is Surface Profile Depth Quantified? Precision and Bias 8. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.


These changes reflect industry research on current tooling which revealed averaged measurements are consistently less than the values obtained using replica tape. Inspection Instruments Pipeline Coatings — Volume 2: Hold the gage by its base and press? ICS Number Code Last previous edition approved in as D — 93 Then determine the mean for all the locations and report it as the pro?

Standards for Measurement of Surface Profile. At each location make ten readings and determine the mean. The standard does not address discarding outliers, but an update to the standard addressing outlier readings is planned.

Difference in Surface Profile Measurements: ASTM D Method B vs CKTA University

Visual Comparator – This test method, as well as the comparator discs available on the market, have stayed the same, and therefore there were no updates for this test method. The depth is displayed on the gage in mils 0.


The distance from the bottoms of many of the deepest valleys to the tops of the highest peaks maximum pro? Leave a Reply Cancel c4417 Your email address will not be published. At each location make three readings and determine the mean. Do not drag the instrument across the surface between readings, or the spring-loaded tip may become rounded leading to false readings.

This method can be used to measure the surface profile depth that is created by abrasive blast cleaning or impact-type power tools.

Differences in Surface Profile Measurements: ASTM D4417- Method B vs. Method C

Both the structure and the coating system protecting the structure will move while astk service. The four standards are: The three test methods described within D for measuring surface profile include visual comparators, surface profile depth micrometers, and replica tape. There are additional techniques suitable for laboratory use not covered by these test methods.
