A new ASTM International standard will allow users to grow a standardized bacterial biofilm that can be used in the efficacy evaluation of antimicrobial disinfectants. The new standard (soon to be published as E3161) was developed by the ASTM International committee on pesticides, antimicrobials, and alternative control agents ( E35 ). According to committee members, bacteria may grow and…, Pseudomonas aeruginosa, or, Staphylococcus aureus, biofilm that can be used to evaluate the efficacy of antimicrobial disinfectants.

ASTM International’s soil-and-rock committee ( D18 ) is developing a standard for particle-size analysis when specifiers want both a sedimentation and sieve analysis on a soil sample. The proposed standard ( WK38106 ) will complete a suite of three standards that cover procedures previously contained in a now-withdrawn standard (D422). According to the committee, while there is no direct…, 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 #10529

A first-of-its-kind ASTM International guide outlines the many test methods used to evaluate the effectiveness of antifungal-treated articles. While other standards have been developed for antimicrobial-treated articles, the new guide is the first of its kind to focus solely on antifungal test methods, according to member Daniel Price, the director of microbiology at Interface Inc. He says that…, 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 #10525

A new ASTM International standard will help measure the effectiveness of antimicrobial agents at preventing biofilms, which are thin films of bacteria that adhere to textiles and other products. The test method will show a treated material’s resistance to microbial colonization and subsequent biofilm formation relative to an untreated (control) sample. The standard is specifically designed to…, 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 #10522

A new ASTM International standard will support the use of stucco in the construction industry. The new standard (soon to be published as C1860) was developed by the ASTM International committee on gypsum and related building materials and systems ( C11 ). “The new standard provides a way to measure the tensile strength or bond strength of stucco in vertical applications,” says ASTM International…, About ASTM International, Committed to serving global societal needs, ASTM International positively impacts public health and safety, consumer confidence, and overall quality of life.

A new ASTM International standard uses a portable, vertical water-jet probe to measure sand detachment and to evaluate erosion related to storms. The standard describes the components and recommended testing scheme for the “in-situ erosion evaluation probe” (ISEEP), including how to monitor the rate of advancement of the jetting probe, according to Mohammed Gabr, a member of ASTM International’s…, 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 #10506

A new ASTM International standard will support major projects such as roads, bridges, and other structures by providing a modern standard for load testing of deep foundations. The new standard ( D8169/D8169M ) was developed by ASTM International’s committee on soil and rock (D18). For more than 100 years, full-scale static load testing has helped engineers who create deep foundation designs.…, 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 #10491

All interested parties are invited to help develop standards for ASTM International’s subcommittee on grouting, part of the committee on soil and rock ( D18 ). The purpose of the grouting subcommittee ( D18.16 ) is to promote grouting practices by developing specifications and test methods related to the characterization of properties and behavior of chemical and particulate grouts, as well as…, in situ, cohesion test, and water pressure tests, among others. These tests are regularly performed at construction sites, but without the underpinning of unified testing methods for them. “Beyond these applications, there is major crossover and common interest between grouting and the oil industry, whether for drilling, formation damage, or wellbore stability,” says Germaine. Anyone can become an ASTM…, About ASTM International, Committed to serving global societal needs, ASTM International positively impacts public health and safety, consumer confidence, and overall quality of life.

A new ASTM International standard will help test organophilic clay, a product that is increasingly used to help remove oil and other materials as part of environmental remediation projects involving groundwater, soil, and sediment. Potentially harmful substances stick to the clay’s surface, helping filter them out. “This new standard can be used as an index test for the evaluation of the oil…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org
