What is the ASTM standard for accelerated aging?

 

1. ASTM G154 Standard: Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Nonmetallic Materials. This standard specifies the operating procedures and requirements for accelerated aging testing using fluorescent ultraviolet lamps.

 

2. ASTM G155 standard: "Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials". This standard specifies the operating procedures and requirements for accelerated weathering tests using xenon arc lamps.

3. ASTM D4329 Standard: "Plastic Aging Test Method Using Fluorescent Ultraviolet (UV) Lamp and Water Circulation Device" (Standard Practice for Fluorescent UV Exposure of Plastics), which specifies the accelerated aging of plastic materials using fluorescent ultraviolet lamp and water circulation device method of testing.

 

4. ASTM D4587: Standard Practice for Fluorescent UV-Condensation Exposures of Paint and Related Coatings. This standard specifies the method for accelerated aging testing of coating materials using xenon arc lamps and water circulation apparatus.

 

These standards describe in detail aspects such as the method of conducting accelerated aging tests, equipment requirements, specimen preparation, test conditions, and data recording. Depending on the specific material type and application, selecting the applicable ASTM standard for accelerated aging testing will help ensure consistency and comparability of testing. Note that these are just some of the commonly used ASTM accelerated weathering standards, and the society has developed other standards related to materials and testing.
