ASTM International will hold an organizational meeting to potentially create a new technical committee that develops voluntary consensus standards for the recycled vulcanized rubber industry. This includes both rubber and carbon black and has many practical applications including use in plastics, strengthening concrete, and infill for playgrounds. This, online meeting, is Wednesday, October 5 2016, at 10:00am EDT. Industry stakeholders and other parties interested in charting a path towards standardization for this industry are welcome to attend. Consensus standards could set a bar for this growing industry resulting in high-quality practices and products used worldwide. The objectives of the meeting are to: • bring a range of industry experts together…, ASTM Recycled Vulcanized Rubber Meeting:, Wednesday, 5 October 2016 at 10:00am (Eastern); online (Webex) meeting, Media Inquiries:, Dan Bergels, tel +1.610.832.9602; dbergels@astm.org, ASTM Staff Contact:, Joe Koury, tel +1.610.832.9804; jkoury@astm.org Release #10165
