Micom Laboratories is proud to announce that it now offers the ASTM D4329 as part of its offering for UV testing services. ASTM D4329 is aimed at three large applications: general use, automotive and polymer building products. Since it is based on practice ASTM G154, this test method is employed for performing accelerated aging on polymers to assess their capacity to uphold their mechanical properties. These include: flexibility, tensile and elongation along with other properties.
While testing to this test method, you should keep in mind the following:
- To the extent possible, test your product side-by-side with a similar material with a known field history (control).
- At multiple time intervals, monitor your product’s performance by measuring relevant mechanical properties. Doing so, it will provide you with a better understanding of your product’s behavior. It will also help you extrapolate its performance as a function of time to some extent.
While this test method uses a fluorescent light source, other practices, for instance ASTM G155, use Xenon Arc UV light sources. Both of these UV light sources are used to predict the effect of sunlight exposure, either outdoor or indoor, on your product on an accelerated basis. To determine which is best suited for you specific needs, please see; The Difference between ASTM G154 and G155 and which is Right for you.
Micom offers polymer testing services for a wide selection of material and products. For more information about the ASTM D4329 test, do not hesitate to get in touch with our specialists.
Micom Laboratories is a third party industrial material testing laboratory accredited by the Standards Council of Canada, CGSB, ISTA and many other organizations.

My career has been focused on simulating real life in the lab under controlled yet accelerated conditions. My passion for lab testing lead me to start Micom Laboratories Inc. 16 years ago. Through time I made sure Micom has the necessary equipment to simulate various environmental parameters such as the sun, vibrations, heat, cold, thermal shocks and humidity. I wanted to be able to move things back and forth, apply stresses to the products and materials we test and see how they react to the various stimuli. To do so we test products and materials against known standards and specifications (certification) and in many cases by creating my own test protocols and specifications (this is the cherry on top of the sundae…). This is what led me to participate in many standards writing committees and to become chairman of some of these committees.
