A proposed ASTM International standard will help in analysis for trace metals using air and wipe sampling practices. ASTM’s air quality committee ( D22 ) is developing the proposed standard ( WK72704 ). The proposed standard covers the digestion of airborne and surface dust samples (collected using air and wipe sample practices) and associated quality control samples for the determination of…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #11027 ###

In light of COVID-19 (coronavirus) and growing safety concerns for members and staff, ASTM International announced today that previously scheduled April standards development meetings in Boston (March 29-April 3) and Prague (April 27-30) have been canceled. The decision was based on several factors, including, but not limited to: Continued review of information and recommendations from the U.S.…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org Release #10993

A proposed ASTM International standard-guide could help examine the range of commercially available methods for analyzing formaldehyde concentrations in indoor air. While formaldehyde is a naturally occurring substance, chronic long-term exposure can potentially lead to health issues, according to the World Health Organization’s report on formaldehyde in indoor environments. ASTM…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #10964

A proposed ASTM International specification will fill the need for a standard covering the use of colloidal silica, a versatile nanoparticle used in concrete that aids in durability. ASTM’s concrete and concrete aggregates committee ( C09 ) is developing the proposed release (WK60809). “Practical applications for colloidal silica in concrete include everything from walkway pavements to building…, 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 #10922

ASTM International’s concrete and concrete aggregates committee ( C09 ) has developed a test method aimed at improving and standardizing the way that resistance of concrete to electrical current flow helps assess its durability. According to ASTM International member R. Douglas Hooton, saturated specimens of hardened concrete are tested to see how well they resist electrical currents. Concrete’s…

A new ASTM International standard will help minimize microbial contamination of culture plate media and sampling devices used in indoor air quality investigations. The standard describes how to sample and transport culturable airborne fungi and bacteria samples using agar plates. “This standard is valuable when species-level identification or quantity of fungi and bacteria are important factors…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #10680

ASTM International’s air-quality committee ( D22 ) is developing a standard that will help test and set assessment criteria for the performance of air quality sensors installed around cities, communities, and industrial sites. Specifically, the proposed standard ( WK64899 ) will outline laboratory and field tests that provide information on instrument repeatability, sensitivity, linearity, cross…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #10641

A proposed ASTM International guide will help concrete professionals use mortar mixtures to compare the relative performance and compatibility of concrete materials. The guide standardizes procedures used for many years in material-performance investigations, according to ASTM International member Ara Jeknavorian of Jeknavorian Consulting Services. “This diagnostic tool will provide concrete…, 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 #10466
