ASTM D6944 standard now offered at Micom Laboratories

Micom Laboratories is proud to announce that it now offers the ASTM D6944 standard as part of its coating testing services. This method uses a thermal and humidity cycling test in order to evaluate the repercussions of repeated thermal stress on the adhesion ability of a coating system. However, this test protocol only supplies the test conditions that are required for inducing the deterioration of coating of the specimen. Hence, this standard has to be paired with another coating test in order to appraise the properties of the sample after an exposure.

ASTM D6944 test

The purpose of ASTM D6944 is to assess how thermal stresses influence the adhesion ability of the coating system through the use of a thermal cycling test. Actually, the latter corresponds to a particular type of accelerated aging tests by the fact that it exposes the sample to a structured cycle of several temperatures for a specific period of time in order to induce the decaying of the coating system on a hasten basis. Indeed, this method describes two different stress cycle procedures as a means to appraise the behavior of the coating towards thermal stress. On the one hand, method A relies on a three-stage cycle consisting of a freeze, thaw and immersion period. On the other hand, method B is the same as method A, but it omits the immersion phase in its sequence. It is important to keep in mind that this practice only provides the test conditions that are required for the execution of the experiment and that it needs another test protocol in order to evaluate the attributes. Lastly, the results obtained cannot be used to foresee the service life of the coating system.

Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM D6944 test, we invite you to contact our material testing laboratory today. It will be our pleasure to answer your questions about either of those tests.

Micom Laboratories is a third party industrial material testing laboratory accredited by the Standards Council of Canada, CGSB, ISTA and many other organizations.

Before establishing Micom Laboratories in 1999, Michel, who also holds a Master’s degree in Physical Chemistry, gained extensive experience over a 14-year tenure managing departments spanning physical chemistry, physics, mechanical and material testing in research and contract laboratories. This exposure granted him a profound understanding of the intricacies of development and material testing processes.

In addition to his practical experience, Michel has played influential roles on various voluntary technical committees. He notably, served as the chairperson for CAN/CGSB 44.227 and the Head of the Canadian Delegation for ISO TC 136. He also contributed to the following technical committees: CAN/CGSB 44.229, CAN/CGSB 44.232, ANSI/BIFMA X5.1, ANSI/BIFMA X5.5, ANSI/BIFMA X5.6, ANSI/BIFMA X 5.9 ANSI/BIFMA X5.11, ISTA Certification Council.

Leveraging his unique expertise, he has led Micom Laboratories to become a renowned name in its niche, now operating out of a 16,000-square-foot test facility in Montreal, Canada, and serving a diverse customer base with an array of material and product testing services. Follow Michel on LinkedIn
