ASTM International’s particle and spray characterization committee ( E29 ) is developing a proposed standard that will be used to measure physical and chemical properties of nanoparticles in a variety of industrial realms. The standard ( E3427 ) describes how to use laser-amplified detection/power spectrum analysis to measure the number of physical and chemical properties of nanoparticles,…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Jennifer Tursi, tel +1.610.832.9653; jtursi@astm.org Release #11790 ###

ASTM International’s homeland security applications committee ( E54 ) has published three standards that are designed to assess the performance of protective equipment used by law enforcement officers. These standards cover public order helmets (E3342); ballistic-resistant shields (E3347); and ballistic-resistant helmets (E3368). In addition to publishing the standards, ASTM has established a…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Kevin Shanahan, tel +1.610.832.9660 ; kshanahan@astm.org Release #11630 ###

ASTM International’s road and paving materials committee ( D04 ) has approved a new standard that will allow those in the road construction industry to extend the service life of asphalt mixtures by more accurately predicting and evaluating fatigue performance. According to ASTM member M. Emin Kutay, the new standard ( D8458 ) will be used to assess the resistance of different types of asphalt…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Asley Wiand, tel +1.610.832.9551; awiand@astm.org Release #11610 ###

ASTM International announced today the Journal of Testing and Evaluation, the organization’s flagship journal, received an increased 2021 impact factor rating of 1.333, up 5.5% from the previous year. The impact factor is calculated each year by Clarivate Analytics and given to journals that appear in their database, Science Citation Index. Launched in 1973, the journal is a multi-disciplinary…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org Release #11472 ###

Particle size distribution is an important factor in the manufacture of many products, from cement to perfume. A proposed ASTM International standard ( WK45240 ) will set out a general approach to the particle size distribution measurement of powders, suspensions, or slurries using an appropriate wet or dry methodology by the laser diffraction technique. ASTM’s committee on particle and spray…

A new standard developed by ASTM International’s road and paving materials committee ( D04 ) provides guidance on both blast and steel furnace slag product classification. ASTM defines iron and steel slags as the nonmetallic products of the manufacturing of iron and steel. They can be considered products based on the mineralogy of samples that are tested using this standard as a guide. “The…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #11129 ###

A new ASTM International standard will provide a test method for determining thermal cracking properties of asphalt mixtures through the measurement of thermally induced stress and strain. ASTM’s road and paving materials committee ( D04 ) developed the standard, which will soon be published as D8303. Asphalt pavement in cold climatic regions are highly susceptible to thermal cracking.

A proposed ASTM International standard will help define baseline performance requirements for ballistic-resistant barriers, panels, or structures that are used to protect against complete penetration of projectiles from small arms. ASTM’s homeland security committee ( E54 ) is developing the proposed standard ( WK63319 ), which focuses on items such as rigid or flexible barriers, panels, or…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Mary Mikolajewski, tel +1.610.832.9678; mmikolajewski@astm.org Release #11006 ###
