A new ASTM International standard ( D8408/D8408M ) will help those developing long-term monitoring plans for vapor mitigation systems that prevent intrusion of hazardous gases into buildings. Contaminated soil, groundwater, sewers, and laterals all generate hazardous gases. A vacuum or depression system below a building slab can mitigate these gases from entering the building, thus protecting…

ASTM International’s soil and rock committee ( D18 ) has approved a new standard that will help design engineers and regulators when using rockfall mitigation nettings on construction projects. Geohazard nettings are often used in mountainous regions along roadways to dampen the energy from rocks falling from the mountain side. ASTM International member Mike Koutsourais, PE, geohazard…

ASTM International’s commercial spaceflight committee ( F47 ) is developing new practices for the design of orbital and suborbital space vehicles. The proposed standards will address suggested best practices associated with the design of these vehicles including how well the vehicle accommodates and protects the crew and space flight participants during launch, flight, and return. Specifically,…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11260 ###

ASTM International’s commercial spaceflight committee ( F47 ) has approved a new standard that supports the increasing amount of space travel by improving data exchange between space operators and the Federal Aviation Administration. According to ASTM International member Zheng Tao, as the number and diversity of space operations increase, improved date exchange will help air traffic management…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org , Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11240 ###

ASTM International’s commercial spaceflight committee ( F47 ) is developing a proposed standard that will serve as a guide for medical qualifications for suborbital vehicle passengers. The proposed standard ( WK76057 ) will provide a consensus set of passenger acceptance guidelines that can serve as advice to commercial operators as they develop their own medical programs. Both commercial…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org , Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11228 ###

ASTM International’s soil and rock committee ( D18 ) has developed a new standard that will help in the construction of tunnels, concrete dams, and bridges. According to ASTM International member Jack Touseull, the new standard ( D8359 ) describes a flexible volumetric dilatometer test that is run inside a borehole in rock with a cylindrical probe that expands radially to determine the in situ…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org , Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11195 ###

A new standard developed by ASTM International’s commercial spaceflight committee ( F47 ) establishes a failure tolerance for suborbital vehicles specific to situations of occupant safety. Failure tolerance, also known as fault tolerance, is the ability of a system to continue satisfying safety or operational objectives in the event one or more components fail. “Failure tolerance provides a…, Media Inquiries:, Jaime Martorana, tel +1.610.832.9796; jmartorana@astm.org, Committee Contact:, Katerina Koperna tel +1.610.832.9728; kkoperna@astm.org Release #11123 ###

ASTM International’s soil and rock committee (D18) is developing proposed standards that cover sediment retention fiber rolls (SRFRs) and rolled erosion control products (RECPs). D18’s erosion and sediment control technology subcommittee (D18.25) is developing the proposed standards. Proposed standard WK39691 will help measure the basic physical properties of SRFRs, which are used to inhibit the…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Robert Morgan, tel +1.610.8329732; rmorgan@astm.org Release #11032 ###

A proposed ASTM International standard will help calculate the kinetic energy of simulated rainfall in laboratories. ASTM’s soil and rock committee ( D18 ) is developing the proposed standard ( WK41200 ). Determining the kinetic energy of raindrops is an important factor to be considered when conducting soil erosion studies. Using data collected from determining raindrop size, the proposed…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Katerina Koperna, tel +1.610.832.9728; kkoperna@astm.org Release #11007 ###
