Some instruments have the ability to detect and measure asm individual layer thicknesses in a multi-layer system. All laboratories reported two replicate test results for every panel with each instrument.
We are a non-profit group that run this website to share documents. The travel time is converted into a thickness reading.
A thickness range of 0. 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 and metal. 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.
Please help us to share our service with your friends. Link to Active This link will always route to the current Active version of the standard. Each of eight laboratories tested seven different coated panels using two types of instrumentation.
A rough surface has a tendency to scatter the ultrasonic pulse atsm odd readings may occur occasionally. Last previously edition approved in as D — In addition to potential performance deficiencies, it is uneconomical to apply more material than necessary when coating large areas such as floors and walls.

For rough coatings, a glycol gel is best, provided it is not a contaminant for the coating to be measured. Please fill this form, we will try to respond as soon as possible.
A number in paren parenthese thesess indicates the year of last reappr reapproval.
These seven coated panels were described as the following: Axtm liquids such as liquid soap may be used. Current edition approved July 1, Originally approved in 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. To be able to compare results obtained by different operators, it is essential to measure film thickness carefully. Water is ideal 6d132 smooth, thin coatings. The instrument may allow a user adjustment to prevent this. Summ Summary ary of Test Test Method 3. Coatings must be applied within certain minimum and maximum thickness tolerances in order that they can fulfill their intended function.
Select the method most appropriate for the material being tested. The instrument must be placed directly on ast, coating surface to take a reading.
No other units of measurement are included in this standard. Thank you for interesting in our services. Therefore the reference standard should be smooth. Hold the probe steady during the measurement. Permission rights to photocopy the standard may also be secured from the ASTM website www. 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.
