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 ###

ASTM International’s plastics committee ( D20 ) is developing a proposed standard that will support recovery and recycling of plastics through a circular economy. The proposed standard ( WK87117 ) will cover general guidance, requirements, and terms and definitions to assist in the development, manufacture, and recovery of plastics within a circular flow of resources. The proposed standard will…, 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 #11732 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard specification for a broad range of supplementary cementitious materials (SCMs). According to ASTM International member Larry Sutter, this performance specification ( WK70466 ) will ease the adoption of new materials used for SCMs as established sources become less available. “For a variety of…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11659 ###

A new ASTM International standard supports the design of civil vertiports and vertistops. The standard ( F3423 ) is the result of a five-year effort by ASTM’s unmanned aircraft systems committee ( F38 ). A vertiport is a section of land, water, or structure intended for either manned or unmanned vertical takeoff and landing of aircraft, along with the associated buildings and facilities. A…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11524 ###
