A proposed ASTM International standard will satisfy the need for a practice that describes how to use impulse excitation as a means of detecting defects in metal parts. The nondestructive testing committee ( E07 ) is developing the proposed standard ( WK81106 ). According to ASTM International member Steve James, the proposed standard will provide a proper understanding of the nondestructive…

ASTM International’s soil and rock committee ( D18 ) has approved a new standard that will help engineers find the depth of inaccessible foundations supporting existing structures. Foundation elements covered by the new standard ( D8381/D8381M ) include micropiles, driven piles, bored piles, secant or tangent pile walls, caissons, barrettes, diaphragm walls, and sheet pile walls. The standard is…

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 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 ###

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 ###

A new ASTM International test method will help evaluate soil behavior and soil structure interaction when placed under stress conditions. “It is important to understand and predict how soil might behave during earthquakes, explosions, or even machine or traffic vibrations,” according to Rune Dyvik, expert advisor in laboratory and model testing at the Norwegian Geotechnical Institute. “This test…, 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 #10944

A new ASTM International standard will help manufacturers in the aerospace, power generation, and automotive industries test parts for defects. The organization’s nondestructive testing committee ( E07 ) developed the standard (soon to be published as E3213). Through process compensated resonance testing (PCRT), parts from planes, cars, and more can be tested for defects by vibrating the part…, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, Committee Contact:, Kristy Straiton, tel +1.610.832.9640; kstraiton@astm.org Release #10792

A new ASTM International standard could help improve the properties of soils used for landscape beds, sports fields, and golf courses. The organization’s committee on soil and rock ( D18 ) created the new standard ( D8249 ). The standard covers material characteristics, physical requirements, and sampling for using “rotary kiln produced porous ceramic material” in topsoils. This material can…, 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 #10762
