Which standards does SRCC use to conduct OG-100 certifications?

OG-100 certifications are based on the ICC 901/SRCC 100 Solar Thermal Collector Standard which is available for viewing or purchase on the ICC-SRCC standards page. This ANSI standard sets the technical requirements for these collectors and references many other specific standards. ICC 901/SRCC 100 in turn references the internationally-accepted ISO 9806 Solar Energy – Solar Thermal Collectors –Test Methods standard. This is the same testing standard utilized by other notable international certification programs, including the European Solar Keymark Program, with minor testing variations.
