A rough surface has a tendency to scatter the aatm pulse and odd readings may occur occasionally. Please help us to share our service with your friends.
Some instruments have the ability to detect and measure the individual layer thicknesses in a multi-layer system. We are a non-profit group that run this website to share documents.

ASTM D6132 – 13(2017)
While this is a destructive test method, it will provide an alternative test method to ensure measurements made in accordance with this test method are in the correct range. Thank you for interesting in our services.
Current edition approved July 1, UV cured coating on hickory Panel 2: Last previously edition approved in as D — A number in paren parenthese thesess indicates the year of last reappr reapproval. Summ Summary ary of Test Test Method 3. Measurements may be made on field structures, on commercially manufactured products, or on laboratory test specimens.
These types of gages can accurately measure the dry film thickness of organic coatings on a variety d61322 substrates such as concrete, wood, wallboard, plastic, fiber composites and metal. The instrument must be placed directly on the coating surface to take a reading. Originally approved in The instrument’s ability to detect a distinct interface between the coating and the substrate may be impeded if the coating and the substrate are of similar composition, density or attenuation or if the coating is non-homogeneous.
A thickness range of 0.

No other units of measurement are included in this standard. 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.
Coatings must be applied within certain minimum and maximum thickness tolerances in order that they can fulfill their intended function.

All laboratories reported two replicate test results for every panel with each instrument. Precision and Bias4 These seven coated panels were described as the following: In addition to potential performance deficiencies, it is uneconomical to apply more material than necessary when coating large areas such as floors and walls.
Historical Version s – view previous versions of standard. Link to Active This link will always route to the current Active version of the standard.
For best accuracy, each instrument should be checked against a known thickness of the particular coating being measured and adjusted if necessary. Referenc Referenced ed Documents Documents 2.
Hold the probe steady during the measurement. To be able to compare results obtained by different operators, it is essential to measure film thickness carefully. Permission rights to photocopy the standard may also be secured from the ASTM website www. Approved July 1, The instrument may allow a user adjustment to prevent this.
Water is ideal for smooth, thin coatings. Each of eight laboratories tested seven different coated panels using two types of instrumentation.
The travel time is converted into a thickness reading. No other units of measurement are included in this standard.
For rough coatings, a glycol gel is best, provided it is not a contaminant for the coating to be measured.
