Govlawastmg1542000 Identifier-ark ark13960t34184720 Ocr ABBYY FineReader 110 Extended OCR Ppi 600 Year 2000. More specific information about methods for determining the change in properties after exposure and reporting these results is described in ISO 4582.
ASTM G154-12a 1 Specimens were cut from sample and placed in UV test chamber exposure condition according to cycle 1 of ASTM G154 for 100 hours. Different UV light sources are used depending on the type of material to be tested and conditions. DOWNLOAD OPTIONS download 1 file.
Various cycles are defined depending upon the intended end use application - for example a typical cycle for automotive exterior applications would be 8 hours UV exposure at 70 C followed by 4 hours of condensation at 50 C. General guidance is given in Practice G151 and ISO 4892-1. ASTM G154-06 2549 2283 16 16 2529 99 2265 99.

The sunlight exposure being simulated can either be direct or through window glass. Cal TB 117 Section E. 15 minutes direct spray salt solution at ambient temperature.
Such instruments shall be shielded from the lamp radiation. 1 test cycle is 24 hrs Three stage test 6 hours exposure to a water fogcondensing humidity climate of 100 RH at 50C. This practice is the basis of all of the other standards for accelerated weathering using Xenon Arc UV light sources to simulate exposure to natural sunlight on an accelerated basis.
Be the first one to write a review. Spray cycle control of the blower. Due to time constraints however many producers employ the G and G laboratory chamber tests for reliable exposure results in shorter time periods.
The author feels this will give results which are more consistent test to test and follows the OEM manual re. Accelerated Weathering QUV ASTM G154 ASTM D4329 ASTM D4587 ISO 4892. Spray type Wm2nm.
ASTM G154 and G155 Explained In the ASTM G test xenon arc lamps simulate full-spectrum sunlight within a controlled test chamber. General guidance is given in Practice G151 and ISO 4892-1. Other standards that QUV is part of a cyclic corrosion such as ASTM D5894 ISO 12944-9.
