A new ASTM International specification will help thermal-heat meter manufacturers better standardize accuracy of their products.
The “specification for equipment and instrumentation of heat metering technologies” (soon to be published as E3137) was developed by ASTM International’s committee on solar, geothermal, and other alternative energy sources (E44). The development of the standard was supported by a memorandum of understanding (MOU) signed by ASTM International and the International Association of Plumbing and Mechanical Officials in December 2011.
The MOU established a framework of cooperation for the development of ASTM International standards for heat metering. According to the terms of the MOU, ASTM International serves as the standards developing organization for heat metering, while IAPMO participated in the standards developing process and provides technical expertise.
ASTM International member and U.S. Environmental Protection Agency employee James Critchfield notes that thermal energy technologies and systems have become ubiquitous in industrial, commercial, and residential realms. Also, many jurisdictions (including U.S. states) are developing policies and programs focused on thermal energy.
“The new standard will help the market have greater confidence in the accurate measurement and quantification of the benefits – energy, financial, and environmental – of hydronic thermal energy sources,” says Critchfield, who works in the Office of Air and Radiation at the U.S. Environmental Protection Agency. “This standard is a key step to unlocking more thermal energy capacity in the market.”
In addition to benefiting manufacturers, the standard could help policymakers and program administrators meet their goals. Also, project developers and consumers could gain more confidence that energy products both produce and deliver an accurate and known amount of energy.
Moving forward, Critchfield says that the subcommittee on heat metering (E44.25) is reaching out to laboratories, policymakers, and program administrators to further support testing, verification, and certification related to the specification.
