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 general aviation aircraft committee ( F44 ) has revised their standard for systems and equipment in aircraft. The newly revised standard ( F3061/F3061M ) covers the systems and equipment aspects of airworthiness and design for aircraft. Topics covered in the standard include electrical systems, environmental requirements, manual and automatic flight controls, and flight data…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Joe Koury, tel +1.610.832.9804; jkoury@astm.org Release #11525 ###

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 plastic piping systems committee ( F17 ) has approved a standard that will aid in the design of a new fabricated pipe fittings made from crosslinked polyethylene (CX-PE). The new standard will soon be published as F3525. ASTM International member Robert Samplonius says that F3525 is part of a movement to develop several standards applicable to the specification and…

A proposed ASTM International standard will establish a new practice for determining safe-life, inspection threshold, and reoccurring inspection intervals for airplanes. ASTM International’s general aviation aircraft committee ( F44 ) is developing the proposed standard. According to the U.S. Federal Aviation Administration, the safe-life of a structure is the number of events, such as flights,…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Joe Koury, tel +1.610.832.9804; jkoury@astm.org Release #11295 ###

New standard practices and specifications developed by ASTM International’s plastic piping systems committee ( F17 ) establish requirements and test methods for polyamide-12 (PA12) materials, pipe, and fittings. PA12 line pipe is made using polyamide-12, a specialty type of nylon plastic with exceptional strength and durability compared to other plastics used in pressure piping systems. The new…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Robert Morgan, tel +1.610.832.9732; rmorgan@astm.org Release #11271 ###

A proposed ASTM International standard would address requirements to evaluate small aircraft components as low stress structures. ASTM’s general aviation aircraft committee ( F44 ) is developing the proposed standard. The proposed standard (WK61232) would address requirements for users to designate aircraft components as low stress structures, allowing the user to forgo certain structural…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Joe Koury, tel +1.610.832.9804; jkoury@astm.org Release #11263 ###
