ASTM International’s water committee ( D19 ) has approved a new standard that will be used to identify microplastics in environmental water samples. According to ASTM member and microplastics subcommittee lead William Robberson, P.E., the new test method ( D8401 ) is the first standard that will identify plastic in the environment, and the first that can be used synergistically with other ASTM…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #11834 ###

ASTM International’s water committee ( D19 ) has approved a new standard that will help water producers and users identify and quantify bacteria in potable (drinking, dental, and bottled water) as well as nonpotable water (cooling towers). Heterotrophic bacteria count (HPC) determines the overall number of bacteria in a water sample, allowing water system managers and water treatment…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #11735 ###

ASTM International’s nondestructive testing committee ( E07 ) is developing a proposed standard that will guide the process of electrical conductivity tests for verification of heat treatment of aluminum alloys. The proposed standard ( WK86698 ) contains procedures for verifying aluminum alloy heat treatment by means of eddy current techniques, which measure electrical conductivity. Aluminum…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #11723 ###

ASTM International’s nondestructive testing committee ( E07 ) is developing a proposed standard that will cover composite pressure vessels used for storing and transporting gas at high pressure. According to ASTM member James Mitchell, the most prominent use for the vessels described in the proposed standard ( WK86721 ) is for natural gas virtual pipelines, in which gas is transported from the…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #11709 ###

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 nondestructive testing committee ( E07 ) is developing a standard outlining a new test method for inspection of glass fiber-reinforced polymer products. The method uses a microwave-based system that will make inspecting these products more accessible. The proposed standard itself ( WK85608 ) details the basics of inspection, like equipment set-up, data acquisition,…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #11651 ###

Two proposed standards from ASTM International’s water committee ( D19 ) are devoted to different aspects of water quality. The first proposed standard ( WK68866 ) will provide a screening method to assess contaminants in water samples prior to a more detailed analysis. If approved, this standard will cover the determination of adsorbable organic fluorine (AOF) in waters and waste waters that can…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Brian Milewski, tel +1.610.832.9619; bmilewski@astm.org Release #11643 ###

ASTM International’s concrete and concrete aggregates committee ( C09 ) is developing a proposed standard that will be used to help measure the tensile strength of fiber reinforced concrete. According to ASTM International member Luke Pinkerton, the use of fiber reinforcement as an alternative to conventional reinforcement of various concrete structures has been limited in the construction…, 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 #11599 ###
