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 ###

Particle size distribution is an important factor in the manufacture of many products, from cement to perfume. A proposed ASTM International standard ( WK45240 ) will set out a general approach to the particle size distribution measurement of powders, suspensions, or slurries using an appropriate wet or dry methodology by the laser diffraction technique. ASTM’s committee on particle and spray…
