ASTM International’s soil and rock committee ( D18 ) has developed a new standard that will aid real estate developers with preliminary karst terrain assessment. Karst is a type of terrain characterized by sinkholes, caves, sinking streams and large springs, which is a consequence of the presence of soluble bedrock such as limestone. The new standard provides a protocol for karst assessments that…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11748 ###

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 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 ###

ASTM International’s soil and rock committee ( D18 ) is developing a proposed standard that will provide guidance on analyzing soil for nutrients using hyperspectral sensors. Such sensors are used to collect and process information via the electromagnetic spectrum. ASTM member Penelope Nagel says that agronomists, farmers, agronomic service providers, laboratories and fertilizer companies will…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11550 ###

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 ###
