IAPMO R&T Announces New Draft American National Standard for Rating Solar Heating Collectors Available for Public Comments, Due March 9

Ontario, Calif. — IAPMO R&T, a leading developer of standards for the plumbing, mechanical and solar industries, is pleased to announce that draft standard IAPMO/ANSI S1001.4, Energy Production Rating of Solar Heating Collectors, is available for public review and comments. Notice of availability and 45-day public review was published in the Jan. 23 issue of ANSI Standards Action:

IAPMO (Z) (International Association of Plumbing and Mechanical Officials) New Standard BSR/IAPMO S1001.4-201x, Energy Production Rating of Solar Heating Collectors (new standard) This Standard specifies the procedures used to determine energy production ratings of solar heating collectors, which provide a basis for comparing the relative thermal performance of various solar collector technologies when evaluated under identical rating conditions. Ratings help users of solar heating products make an informed decision regarding the choice of collector with respect to thermal performance in a variety of end-use applications. Single copy price: Free Obtain an electronic copy from: standards@IAPMOstandards.org Order from: les.nelson@IAPMO.org

Send comments (with copy to psa@ansi.org) to: Abraham Murra (909) 472-4106, abraham.murra@IAPMOstandards.org

IAPMO’s S1001 Solar Standards Technical Subcommittee members met in a collaborative and open process to develop this draft solar heating collector rating standard, which is completely transparent and allows the user to convert the results of test laboratory thermal efficiency tests to a single-day collector energy production rating. This standard, along with the accompanying IAPMO Solar Calculator, will allow manufacturers, distributors, architects, engineers, contractors, code authorities, program administrators and end-users to compare the energy production of tested solar heating collectors. For 87 years The IAPMO Group has offered a comprehensive menu of services — product testing and certification, code and standard development, training and education — offering clients one-stop shopping for all of their solar, plumbing and mechanical needs.
