ASTM standard will help improve levelness, smoothness, and flatness of existing floors ASTM International’s concrete and concrete aggregates committee ( C09 ) approved a new standard that will be used to evaluate the performance of floor patching and skim coating compounds. These compounds, which contain hydraulic cement, are used to improve the levelness, smoothness, and flatness of existing…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Scott Orthey, +1.610.832.9730; sorthey@astm.org Release #11869 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard ( WK73384 ) that will evaluate the tensile performance of fiber-reinforced concrete using cylindrical specimens with double-punch loading. The proposed standard contains “pre- and post-peak tensile properties (that) hold great significance in fiber-reinforced concrete (FRC) and ultra-high-…, 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 #11676 ###

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 ###

ASTM International’s rubber and rubber-like materials committee ( D11 ) is working on a proposed standard to address variation between laboratories resulting from bias. The standard guide ( WK85445 ) is part of the lineage formed by ASTM D4483 , which has helped committee members improve testing precision within labs over the past several decades. However, according to John Bailey, chair of the…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Melissa Marcinowski, tel +1.610.832.9626; mmarcinowski@astm.org Release #11657 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a new standard for economical testing of concrete strength. The proposed standard, WK82351 , will provide a fast, simple, non-destructive method for testing concrete strength that can be performed almost anywhere. According to ASTM International member Neil Cox this method, which measures the dominant resonant…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Scott Orthey, tel +1.610.832.9730; sorthey@astm.org Release #11488 ###

ASTM International’s committee on rubber and rubber-like materials ( D11 ) has approved a new standard for evaluating anesthesia reservoir bags. Anesthesia reservoir bags are used while performing inhalation sedation to provide a reservoir from which additional gas may be drawn should the respiratory demands of a patient exceed the gas flow delivered from the breathing system. According to ASTM…
