A newly approved standard, ASTM D7338 , Guide for the Assessment of Fungal Growth in Buildings, has been developed to provide a go-to reference for anyone testing for mold in buildings. The new standard was developed by Subcommittee D22.08 on Sampling and Analysis of Mold, part of ASTM International Committee D22 on Air Quality. “The lack of consensus standards in the fungal sampling and analysis…, ASTM Committee D22 Next Meeting:, April 10-13, April Committee Week, Anaheim, Calif., Technical Contact:, Lisa Rogers, Mycometer, Inc., Tampa, Fla., Phone: 813-831-6511; lrogers@mycometer.com, ASTM Staff Contact:, David Bradley, Phone: 610-832-9681; dbradley@astm.org, ASTM PR Contact:, Barbara Schindler, Phone: 610-832-9603; bschindl@astm.org Release #8788

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

Air permits from regulatory agencies, such as the U.S. Environmental Protection Agency (USEPA), often require the measurement of a plume's opacity as the plume is emitted from a stationary point source (for example, smokestacks) in the outdoor ambient environment. While such opacity is often visually measured by human observers as “certified smoke readers,” an opacity measurement method using…

The measurement of acid mist is becoming increasingly important due to recent actions taken by the U.S. Environmental Protection Agency on fine particles (2.5 micrometers in diameter and smaller) that are unhealthy to breathe. ASTM International Committee D22 on Air Quality is currently working on a proposed standard for measuring acid mists that come from combustion sources, WK22846 , Test…

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…

A new ASTM International standard provides guidance for using data generated by ASTM standards in testing for asbestos in surface dust. ASTM D 7390 , Guide for Evaluating Asbestos in Dust on Surfaces by Comparison Between Two Environments, was approved by ASTM International Committee D22 on Air Quality, part of Subcommittee D22.07 on Sampling and Analysis of Asbestos. According to James Millette…

While the polymer-based siding industry developed around the use of polyvinyl chloride, the last two decades have seen the introduction and rise in use of polypropylene as a siding material. Because of this, siding producers and polypropylene suppliers began to discuss the need for an ASTM standard for this type of siding. These discussions have resulted in the development and recent approval of…

ASTM International Committee D20 on Plastics is currently developing a proposed new standard that will be used for the determination of flammability characteristics of polymeric materials under laboratory conditions. The proposed standard, WK9492 , Test Method for Determining Flammability Characteristics of Plastics and Other Solid Materials Using Microscale Combustion Calorimetry, will be useful…
