Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…

Consumers who are purchasing building materials for homes want to be assured that the materials are mold resistant. A proposed new ASTM standard will allow for a mold-resistance rating to be given to specific materials, depending on how the materials perform to the test method. The proposed new standard, ASTM WK32079 , Test Method for Determination of Mold Growth on Building Products Designed for…

ASTM Committee G02 on Wear and Erosion is including a field trip in the plans for its Dec. 8-9 meeting in Jacksonville, Fla. Committee members will be visiting the Tribology Laboratory in the mechanical engineering department at the University of Florida in Gainesville. The Tribology Laboratory is actively involved in a wide variety of tribological research and tribology education projects. The…

The Resin Identification Code (RIC) system is a means of sorting different types of plastics from household waste. The RIC was developed by the Society of the Plastics Industry in 1988. The RIC assigns a numeral from 1 to 7, with a “chasing arrows” symbol around the number, to a piece of plastic to indicate its type. SPI recognized the importance of the involvement of the technical stakeholder…, ASTM Committee D20 Next Meeting:, Nov. 14-17, November Committee Week, San Antonio, Texas, Technical Contact:, Thomas Pecorini, Eastman Chemical Co., Kingsport, Tenn., Phone: 423-229-5917; tjpec@eastman.com, ASTM Staff Contact:, Brynn Murphy, Phone: 610-832-9640; bmurphy@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8682/Sept2010

A new ASTM standard will be useful to slide and engine companies, as well as makers of bushing materials, in studies that involve the measurement of system friction forces. The new standard, ASTM G203 , Guide for Determining Friction Energy Dissipation in Reciprocating Tribosystems, was developed by Subcommittee G02.50 on Friction, part of ASTM International Committee G02 on Wear and Erosion.…

While standards for outdoor calibration techniques for solar radiometers exist, there are currently no general standards that deal with issues of indoor calibration transfers between radiometers of different design. A proposed new ASTM standard, ASTM WK27263, Test Method for Indoor Transfer of Calibration from Reference to Field Pyranometers, will address in detail issues associated with…

Explorations into alternative forms of energy have increased interest in standards for solar energy applications. ASTM International Committee G03 on Weathering and Durability has recently approved a new standard in this area, G197 , Table for Reference Solar Spectral Distributions: Direct and Diffuse on 20° Tilted and Vertical Surfaces. ASTM G197 was developed by Subcommittee G03.09 on…

A proposed new ASTM International standard will facilitate more efficient recycling of a variety of post-consumer plastics. The proposed standard, WK20632, Practice for Marking Plastic Products for Identification in Reuse and Recycling, is under the jurisdiction of Subcommittee D20.95 on Recycled Plastics, part of ASTM International Committee D20 on Plastics. ASTM WK20632 is based on an original…

All interested parties are welcome to join in the standards developing activities of ASTM International Committee D20 on Plastics. Current D20 projects such as the development of proposed new standards covering backed vinyl siding and bioreactor landfill conditions demonstrate the diversity of D20’s work., Backed Vinyl Siding, Subcommittee D20.24 on Plastic Building Products is developing WK18425 , Specification for Rigid Poly (Vinyl Chloride) (PVC) Siding with Foam Plastic Backing (Backed Vinyl Siding). Vinyl siding with an integral foam plastic backing has been commercially available for nearly a decade. Because backed-vinyl siding is a variation of the basic siding product, testing and third party certification for…, Biodegradability of Plastics in Landfill Conditions, A proposed new standard being developed by Subcommittee D20.96 on Environmentally Degradable Plastics and Biobased Products will aid in the determination of degradation and biodegradation of plastics in landfill environments. All interested parties are encouraged to participate in the development of WK18427 , Determining the Aerobic Degradation and Anaerobic Biodegration of Plastic Materials…
