A new ASTM International standard ( D8560 ) will help to determine the presence of polyfluoroalkyl substances (PFAS) in the indoor air environment. ASTM’s air quality committee ( D22 ) developed the new standard. According to ASTM member Dustin Poppendieck, quantifying PFAS concentrations in indoor air is important for accurate and meaningful exposure analysis and risk assessments since some PFAS…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #11832 ###

ASTM International’s plastics committee ( D20 ) has revised an important standard that supports using radiocarbon analysis to determine the biobased content of solid, liquid and gaseous samples. The revision includes an update of the atmospheric adjustment factor (REF) value that is used in product analysis for biobased and biogenic carbon content. The revised standard ( D6866 ) is used to report…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Alyson Fick, tel +1.610.832.9710; afick@astm.org Release #11787 ###

A proposed ASTM International standard will establish the first test method for determining humus generation during biodegradation. ASTM International’s plastics committee ( D20 ) is developing the proposed standard. Humus is the portion of soil, dark in color and complex in chemical nature, that is made up of partially degraded biomass. As biodegradation of natural materials occurs, the humus…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Alyson Fick, tel +1.610.832.9710; afick@astm.org Release #11269 ###
