ASTM International’s performance of buildings committee ( E06 ) is developing a proposed standard ( WK70955 ) that will help evaluate potential impacts of changes to the thermal and moisture properties of roof assemblies and the conditioning of space below roof decks. Specifically, the standard could help evaluate steep-sloped roof assemblies after: adding insulation; making alterations in…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Stephen Mawn, tel +1.610.832.9726; smawn@astm.org Release #10970

A new ASTM International standard will help measure how well wall-mounted kitchen range hoods capture indoor air pollutants. This could help organizations that rate the products and, in turn, consumers who buy them. “Cooking has been identified as a major source of indoor air pollutants in homes,” says ASTM International member Iain Walker, a scientist at the Lawrence Berkeley National…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Stephen Mawn, tel +1.610.832.9726; smawn@astm.org Release #10434

A proposed new ASTM International standard will help determine how well a kitchen range hood exhausts pollutants from a stovetop. These pollutants include moisture, odors, and chemicals and particles that are health hazards. The proposed standard (WK55797, Test Method for Measuring Capture Efficiency of Domestic Range Hoods) is being developed by ASTM International’s committee on performance of…, ASTM Committee E06 on Performance of Buildings Next Meeting:, April 2-5, 2017, April Committee Week, Toronto, Ontario, Canada, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Technical Contact:, Iain Walker, Lawrence Berkeley National Laboratory, Berkeley, Calif., tel +1.510.486.4692; iswalker@lbl.gov, ASTM Staff Contact:, Stephen Mawn, tel +1.610.832.9726; smawn@astm.org Release #10252
