(ASTM: West Conshohocken, PA) -- Manufacturers of solar radiometers, and testing laboratories for solar energy, materials and durability testing will be among the primary users of a new ASTM International standard that outlines procedures using indoor test methods to calibrate radiometers with dissimilar detectors.

The new standard, ASTMG207 —“Test Method for Indoor Transfer of Calibration from Reference to Field Pyranometers,” was developed by Subcommittee G03.09 on Radiometry, part of the ASTM International Committee G03 on Weathering and Durability. ASTM G207 facilitates calibration of solar sensors used in accelerated testing under simulated sunlight and outdoor weathering tests as well as performance monitoring of solar energy conversion systems.
