Some Industry References and Results Evaluation for Aging Testing

To understand the aging resistance of a material or product, it is necessary to do some artificial accelerated aging tests. The following are some common aging test items and standards.

conventional products

ASTM G151, ASTM G154, ASTM G155, JIS D 0205, SAE J2020

Coating aging test standard

ASTM D3794, ASTM D3451, ASTM D4587, ASTM D3794, Israeli Standard No. 330, 385, 935, 1086, ASTM D6695, Korean Standard M598-1990, ISO 11341, NACE Standard TM-01-84, NISSAN M0007

Evaluation of Aging Test Results

You can get good durability data with an accelerated weathering Tester. But you need to be aware that the figures you are getting are comparative figures, not absolute figures. The best results you can get from laboratory weathering tests are a reliable indication of the relative durability rating of one material versus another. In fact, the same argument applies to the Florida exposure test.

Nobody knows how a year of exposure in a 5° south facing outdoor "black box" would compare to a year of aging in a room or car. Even outdoor testing can only give a relative indication of actual runtime. However, comparing data can be very effective.

For example, you might discover that a small change in design could double the durability of a standard material. Alternatively, you may find identical looking materials from multiple suppliers, some of which will age quickly, most of which will take a moderate amount of time to age, and a small percentage of which will take longer to age when exposed to sunlight . Or you may find that for a standard material that performs satisfactorily over a practical lifetime (say 5 years), a less expensive design is equally durable.
