New Standard for Chemical Permeation Testing Approved by ASTM Personal Protective Clothing CommitteeChemical protective clothing has been widely used to protect skin from health hazards that can be found in the workplace or during a terrorist attack. A new ASTM International standard provides directions in using a computer program, called a permeation calculator, to analyze data following a permeation test, in order to determine when chemicals have gotten inside the clothing. The new standard,…

ASTM grain size is a property written into many specifications for metals, with finer grain sizes generally indicating better mechanical properties, such as formability. While measuring certain materials for such properties can be difficult, electron backscatter diffraction can provide precise determinations as well as give information on grain size distribution and statistics. A new ASTM…

The ability to provide the correct amount of protection is one of the important elements in the development of protective clothing worn by individuals who apply pesticides as part of their jobs. While overprotection in hot climatic conditions can result in heat stress and low compliance, some of the existing design-based requirements can result in too little protection, as material performance…, CONTACT:, ASTM Committee F23 Next Meeting:, Jan. 26-28, 2010, January committee week, San Antonio, Texas, Technical Contact:, Anugrah Shaw, University of Maryland Eastern Shore, Princess Anne, Md., Phone: 410-651-6064; ashaw@umes.edu, ASTM Staff Contact:, Stephen Mawn, ASTM International, Phone: 610-832-9726; smawn@astm.org, ASTM PR Contact:, Barbara Schindler, ASTM International, Phone: 610-832-9603; bschindl@astm.org Release #84 54/Jan2010
