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.
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.
ASTM G154 is an accelerated UV ageing test using Specific Fluorescent lights to simulate the impact of sun exposure on paints, coatings and polymers.
27 sty 2023 · ASTM G154-23. Standard Practice for Operating Fluorescent Ultraviolet (UV) Lamp Apparatus for Exposure of Materials. Significance and Use. 5.1 The use of this apparatus is intended to induce property changes consistent with the end use conditions, including the effects of the UV portion of sunlight, moisture, and heat.
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).
QUV testing is used to simulate outdoor and indoor sun exposure on surface finishes and coatings and polymers. ASTM G154 is a practice used to do QUV testing. However, there are many test methods requiring QUV testing. Below is a partial list of the test methods we can test to.
When to use ASTM G154? Whenever you want to see how your adhesive performs in certain weather scenarios, accelerated weather testing will give you the ability to do just that. In our opinion, ASTM G154 will give you the best framework to match the conditions you need.
