A new ASTM International standard ( D8560 ) will help to determine the presence of polyfluoroalkyl substances (PFAS) in the indoor air environment. ASTM’s air quality committee ( D22 ) developed the new standard. According to ASTM member Dustin Poppendieck, quantifying PFAS concentrations in indoor air is important for accurate and meaningful exposure analysis and risk assessments since some PFAS…, Media Inquiries:, Gavin O’Reilly, tel +1.610.832.9618; goreilly@astm.org, Committee Contact:, Ashley Wiand, tel +1.610.832.9551; awiand@astm.org Release #11832 ###

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…

ASTM International’s air quality committee ( D22 ) is developing a proposed standard that will aid in the removal of gases that are harmful to both people and to the environment. The proposed standard covers the proper destruction of gaseous fugitive emission by thermal oxidizer or catalyst. According to J. David Halley, chair of ASTM’s gaseous fuels committee ( D03 ), chemical manufacturers are…

A new ASTM International standard describes a range of techniques that can be used to analyze formaldehyde concentrations in indoor air. ASTM’s air quality committee ( D22 ) developed the standard, which will soon be published as D8407. A naturally occurring organic compound, formaldehyde is an ingredient in many materials, such as resins used for particleboard and coatings. “Formaldehyde is a…
