Approved July 1, Summ Summary ary of Test Test Method 3. Referenc Referenced ed Documents Documents 2. 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 asm similar composition, density or attenuation or if the coating is non-homogeneous.
No other units of measurement are included in this standard. To be able to compare results obtained by different operators, it is essential to measure film thickness carefully.
Link to Active This link will always route to the current Active version of the standard. A thickness range of 0.
Each of eight laboratories tested seven different coated panels using two types of instrumentation. All laboratories reported f6132 replicate test results for every panel with each instrument. Coatings must be applied within certain minimum and maximum thickness tolerances in order that they can fulfill their intended function.
It is the responsibility of the user of aetm standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Please copy and paste this embed script to where you want to embed Embed Script. A rough surface has a tendency to scatter the ultrasonic pulse and odd readings may occur occasionally.
Some instruments have the ability to detect and measure the individual layer thicknesses in a multi-layer system. These types of gages can accurately measure the dry film thickness of organic coatings on a variety of substrates such as concrete, wood, wallboard, plastic, fiber composites axtm metal.

A number in paren parenthese thesess indicates the year of last reappr reapproval. The instrument may allow d6123 user adjustment to prevent this.
Originally approved in For rough coatings, a glycol gel is best, provided it is not a contaminant for the coating to be measured. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Water is ideal for smooth, thin coatings.
Current edition approved July 1, Therefore the reference standard should be smooth. The instrument must ashm placed directly on the coating surface to take a reading. Measurements may be made on field structures, on commercially manufactured products, or on laboratory test specimens. Please help us to share our service with your friends. We need your help!

The travel time is converted into a thickness reading. In addition to potential performance deficiencies, it is uneconomical to apply more material than necessary when coating large areas such as floors and walls.

Some instruments have the ability to detect and measure the individual layer thicknesses in a multi-layer system. Hold the probe steady during the measurement. 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. UV cured coating on hickory Panel 2: Thank you for interesting in our services. Other liquids such as liquid soap may be used. For best accuracy, each instrument should be checked against a known thickness of the particular coating being measured and adjusted if necessary.
Last previously edition approved in as D — These seven coated panels were described as the following:
