ASTM D4332 test now offered at Micom Laboratories

Micom Laboratories is pleased to announce that it now offers the ASTM D4332 test as part of its offering for packaging testing services. This standard details a procedure which duly conditions the specimen before it undergoes the actual testing. Indeed, by simulating particular field conditions that are encountered at different stages of the distribution environment of the material, it is possible to obtain reproducible and worthwhile results toward the behavior of the sample in a specific setting. Lastly, this method differs from ISTA testing by the fact that it only supplies the atmospheric conditions and it relies on other standards in order to assess certain attributes.

ASTM D4332 test

The goal of ASTM D4332 is to create a conditioning atmosphere that may be employed to appraise the variations of the physical properties of the specimens by providing the guidelines required to do so in a reproducible manner. Indeed, changes in physical attributes tend to occur when the material of the package or of the container is exposed to a change of temperature and relative humidity. Hence, by exposing the sample to an environment of controlled temperature and relative humidity for a specific period of time, it is possible to evaluate the changes in physical properties that transpire in the material when it is exposed to a different temperature and relative humidity. However, in order to fully characterize the evolution of the physical properties, it is necessary to pair this method with a standard that assesses the desired attributes. In the event that the end conditions are similar to the ambient ones, ASTM D4169 should be considered. Lastly, it is important to keep in mind that the simulation does not necessarily duplicate the actual field conditions.

Micom offers polymer testing services for a wide selection of materials and products. For more information about the ASTM D4332 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
