ASTM D4355 test now offered at Micom Laboratories

Micom Laboratories is proud to announce that it now offers the ASTM D4355 test as part of its offering for polymer testing services. This standard details an accelerated weathering test which allows to assess the deterioration in tensile strength of geotextiles through the use of UV testing. Indeed, this method employs Xenon arc light as an illuminating source in order to characterize this property and it is thus based on the ASTM G155 standard.

ASTM D4355 Test

The main goal of ASTM D4355 is to assess the loss of mechanical properties of a geotextile material through the use of Xenon arc light as an illuminating source. In fact, this standard allows to investigate the effects of multiple factors that are associated with the studied material end use conditions by exposing it to an accelerated weathering test. Indeed, the deterioration that is due to the effects of heat, humidity and solar radiation is at the core of this method. However, the decaying that is caused by localized weather phenomena such as: biological attack and saltwater exposure is not taken into account by this test protocol. More specifically, this standard portrays the evolution of the tensile strength of the material through a deterioration curve that is obtained by evaluating the tensile strength of the sample at predetermined times. From this curve, it is possible to assess the tendency of the geotextile to decay when it is exposed to the test factors. Also, it is necessary to determine an acceleration factor in order to project the performance of the material onto the field from the gathered data of the test.

Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM D4355 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
