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 ) has developed the first material standard ( D8501 ) for PEKK (Poly Ether Ketone Ketone), a thermoplastic resin designed for extreme conditions. According to ASTM International member Alexandra Peters, PEKK performs in continuous use temperature up to 500 ° F (260 ° C), has excellent mechanical strength, and high resistance to flame, smoke, and a…, 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 #11738 ###

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’s dimension stone committee ( C18 ) is developing a proposed standard that will be used to test the resistance of natural stone to long-term freeze-thaw cycles found in colder climates. “Natural stone is widely variable in composition and can include granite, sandstone, marble, and limestone, among others,” says ASTM member Frank Strickland. “This means that the resistance of natural stone…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, David Lee, tel +1.610.832.9681; dlee@astm.org Release #11626 ###

A newly approved standard from ASTM International’s recovered carbon black committee ( D36 ) provides a test that will help to differentiate products and provide a quality control tool for producers and users. Recovered carbon black (rCB) is a recycled product made from end-of-life tires. The new standard (soon to be published as D8474) describes a thermogravimetric (TGA) technique to determine…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Melissa Marcinowski, tel +1.610.832.9626; mmarcinowski@astm.org Release #11602 ###

ASTM International’s plastics committee ( D20 ) is developing a proposed standard that will help polyolefin manufacturers to measure material properties. Polyolefins are used in a variety of applications, including shrink wrap, shopping bags, food packaging, and dishwasher-safe containers, among others. According to ASTM International member Olaf Kohlmann, the proposed standard ( WK81323 )…

ASTM International’s recovered carbon black (rCB) committee ( D36 ) is developing a proposed standard that will be used to differentiate between different rCB products and provide quality control tool for producers and users. According to ASTM International member Pieter ter Haar, the proposed standard ( WK81244 ) will explain how thermogravimetry (TGA), a type of thermal analysis, can be used to…

ASTM International’s dimension stone committee ( C18 ) is developing a proposed standard that will be used to test the resistance of natural stone to long-term freeze-thaw cycles. ASTM International member Frank Strickland notes that the de facto standard for testing freeze-thaw resistance for natural stone has been ASTM standard C666, which describes a pass-fail test for concrete. However, the…

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 ###

A proposed ASTM International standard will aid in the identification of recycled polyethylene materials. The proposed standard ( WK74657 ) presents a classification system that is capable of indicating total recycled content, material origin, physical properties, quality metrics, and regulatory guidance. “This proposed standard will bring together buyers and sellers of recycled materials so…, 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 #11141 ###
