  1. Designation: G154 − 23 Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials1 This standard is issued under the fixed designation G154; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

  2. Accelerated weathering to simulate the damaging effects of long-term outdoor exposure of polymer materials according to ASTM G154, ASTM D4329, ASTM D4587, ISO 4892, SAE J2020.

  3. ASTM G154 is an accelerated UV ageing test using Specific Fluorescent lights to simulate the impact of sun exposure on paints, coatings and polymers.

  5. This standard is issued under the fixed designation G154; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.

  6. Ultraviolet (UV) testing from an accelerated aging perspective finds its roots in photochemistry. This part of chemistry studies light as an energy source to induce chemical reactions (i.e. light is used to provide the required activation energy so that one or more chemical reaction start occurring).

  7. 1.1 This practice covers the basic principles and operating procedures for using fluorescent UV light, and water apparatus intended to reproduce the weathering effects that occur when
