I finished my work just now.At this moment,I’m going to share with you an ASTM standard I just collected, named ASTM g24-13. This standard PDF can be downloaded for free. I hope you can help publicize this website. Next, I will briefly introduce this standard.
ASTM g24-13,Standard Practice for Conducting Exposures to Daylight Filtered Through Glass.
This practice evaluates the resistance of nonmetallic materials to solar radiation filtered through glass in passively ventilated and non-vented enclosures.
Unless otherwise specified, or agreed to by all interested parties, it is recommended that a minimum of three replicatesof each material being tested be exposed. The simultaneous exposure of a similar number of specimens of a control is alsostrongly recommended.
Expose the test specimens, control specimens, and/or specimens of an applicable weathering reference material, (for example, blue wool) in the glass-covered exposure cabinet continuously 24 hours a day and remove from the cabinet only for inspection, return to customer, or to protect specimens from possible damage during severe weather events.
Keywords of this standard:Aging – Exposure Test – Glass – Lightfastness – Non-Metallic Materials – Solar Radiation – Thermal Radiation – Weathering.
To be honest, it’s not easy to find these standard PDFs. I sincerely hope you can support this website more.
