Abstract

This practice covers a test procedure for evaluating absorptive solar receiver materials and coatings when exposed to sunlight under cover plate(s) for long durations. This practice is intended to evaluate the exposure resistance of absorber materials and coatings used in flat-plate collectors where maximum non-operational stagnation temperatures will be approximately 200 Degrees Celicius. This practice does not apply to receiver materials used in solar collectors without cover (unglazed) or in evacuated collectors. This standard was published on 2011-11-22.
