ClearStak Approved as an EPA Accredited Testing Laboratory

ClearStak, LLC, a laboratory located in Putnam, CT has been approved as an ISO 17025 and EPA Accredited testing laboratory. Under the New Source Performance Standards for residential biomass heaters (NSPS), put into effect May 2015 by the Environmental Protection Agency (EPA), all certifying EPA test labs testing residential wood heaters, hydronic heaters and forced air furnaces are required to meet the ISO/IEC standard.

The ClearStak test lab will focus on emissions and efficiency testing of residential biomass heaters. Adding a testing lab in New England will conveniently allow manufacturers of hydronic heaters and other biomass appliances to test their systems to meet the NSPS for decreased particulate levels by 2020.

“We are very excited to start testing appliances to allow manufacturers to continue producing low emissions products. Combined with our extensive background in data acquisition and analysis, we have built our lab with the future of biomass testing in mind,” Laboratory Manager, Kelli O’Brien states.

ClearStak is the first known lab to offer live video streaming and remote data monitoring for complete transparency of testing. Manufacturers and regulators can observe testing wherever they are using mobile and web applications.
