 Adhesion
Testing
Adhesion Testing has a wide range of possibilities for measuring
coating performance. This includes but is not limited to the ability
of a coating/plating to adhere to a substrate to the integrity of
paint layering. |
| |
Standards
- ASTM D3359 Standard Test Method for Measuring Adhesion
by Tape Test
- Daimler Chrysler LP-463PB-15-01 Adhesion and Toughness
- Ford Motor Company BI 106-01 Paint Adhesion Test
- General Motors GM9071P Tape Adhesion Test for Paint
Finishes
Assured Testing Services utilizes many methods as specified such
as multiple tape strengths, knife, cross hatch, scribe, etc. |

Coating/Plating Thickness Measurement
Thickness Measurement (Including ASTM
B499, ASTM B568, GM 4260P, etc.):
Assured Testing Services employs two non-destructive
methods to measure the thickness of coatings or platings over
a substrate. The Magnetic Induction Method measures a non-magnetic
paint over a magnetic substrate. The Magnetic Induction Method
is used for thicker coatings of 1-3 mils. The X-ray Method uses
X-ray Spectrometry to determine the thickness of a plating over
a substrate. The X-ray Method is typically used for very thin
(under 1 mil) platings.

Standards:
- ASTM B499 Measurement of Coating Thickness by the
Magnetic Method: Non-magnetic Coatings on Magnetic Basis Metals
- ASTM B568 Standard Test Method for Measurement of Coating
Thickness by X-ray Spectrometry.
- GM 4260P Method 5 & 9 Measuring Thickness of Electrodeposits
and Anodic Coatings
Capabilities and Equipment:
Assured Testings utilizes a Fischer
MMS Permascope for measurement of coating thickness via the magnetic
induction method. An ASOMA-TCI Model SRF TC5500 X-ray spectrometer
is used to measure the thinner platings.

As noted above, Assured Testing Services
utilizes many methods to determine the adhesion of coatings, plating,
or paints to substrates. These include but are not limited to various
tape strengths, Taber Abrasion, cross hatch, scribes, knife, etc.
Also, the Taber
Abrasion devise is available for testing coating and substrates
such as plastic, rubber and fabric, meeting such specifications
as ASTM D4060. |
