Refer to Practice G for detailed information on the caveats applicable asttm use of results obtained according to this practice. An exposure time that produces a signi?
Test results will depend upon the care that is taken to operate the equipment according to Practice G Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. This practice also covers the preparation of test specimens, and the evaluation of test results.
This cycle may not adequately simulate the effects of outdoor exposure. Validating the specifications, value and safety of your raw materials, products and assets.
Accelerated Weathering (QUV) ASTM G154, ASTM D4329, ASTM D4587, ISO 4892
Table 1 describes commonly used test conditions. Adherence to the standard is mandatory across the GCC region and globally.
Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. E Typical uses do not imply that results from exposures of these materials according to the cycle described will correlate to those from actual use conditions. Therefore, no reference to the use of this practice shall be made unless accompanied by a report prepared according to Section 10 that describes the specific operating conditions used.
Parts may be accommodated depending on size. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Often several exposure times such as, and hours also will be compared to each atsm.
Note 3—Additional information on sources of variability and on strategies for addressing variability in the design, execution and data analysis of laboratory accelerated exposure tests is found in Guide G Other irradiance levels may be used, but must be described in the report. The values given in parentheses are for information only.
Interlaboratory comparisons are valid only when all laboratories use the same design of fluorescent UV device, lamp, and exposure conditions. Satm you to identify and mitigate the intrinsic risk in your operations, supply chains and business processes.
The standard sample holders can hold one sample 3 x 12 inches 75 x mm or two samples 3 x 6 inches 75 x mm.
Where is it tested? Global Reach Intertek is the industry leader with over 42, people in 1, locations in over countries.
The type sstm rate of degradation and the performance rankings produced in exposures to fluorescent UV lamps can be asmt different from those produced by exposures to other types of laboratory light sources.
Accelerated weathering simulates damaging effects of long term outdoor exposure of materials and coatings. Our glass reinforced polyester laminate is tested in a controlled laboratory with a simulation of accelerated weather with an exposure cycle of 8 hours UV followed by 4 hours condensation continuously.
Practice has been withdrawn and replaced by Practice Gwhich describes performance criteria for all exposure devices that use laboratory light sources, and by Practice Gwhich gives requirements for exposing nonmetallic materials in fluorescent UV devices. Current edition approved July 1, All references to exposures in accordance with this practice must include a complete description of the test cycle used.

All specimens shall be exposed simultaneously in the same device. Baked coatings Radiation-cured coatings All other coatings 24 h 24 h 7 days 5. Last previous edition approved in as D — Additional exposure cycles are described in Practice G The spectral power distribution of light from fluorescent UV lamps is significantly different from that produced in light and water exposure devices using other light sources.
