To control the environmental impact of plastic bags and beverage rings, the subcommittee developed the practice for fluorescent ultraviolet exposure of photodegradable plastics (D5208). Marine life consumption of polyethylene carry-out bags and wrappings, as well as both sea and land animals becoming entangled in beverage rings, became major issues in the public eye, says Ronald Walling, president of the Advanced Materials Center Inc. Originally, the group focused on environmental concerns such as composting biodegradable polymers and paper alongside food, yard, and agricultural waste, and the need for compostable diapers. Subcommittee D20.96 then began the hard work of developing these much-needed standards to establish degradability and biodegradability and assess the impact of degraded plastics. These were the early days of environmentally degradable plastics, with no standard practices, test methods, or specifications.

The D20.96 subcommittee organized in 1990 at a time when manufacturers boasted of making eco-friendly products without any verification of their claims. A key group working to alleviate these problems and support safe plastics disposal is ASTM InternationalвЂ™s subcommittee on environmentally degradable plastics and biobased products (D20.96), part of the plastics committee ( D20). According to a study published in Science magazine, roughly eight million metric tons of plastic end up in the worldвЂ™s oceans each year. The remaining 79 percent went into landfills and the environment. According to a report from the Royal Statistical Society, as of 2017, only nine percent of plastic was recycled while 12 percent was incinerated. The amount of plastic waste discarded has galvanized some people against these polymers. Unfortunately, what happens once plastics outlive their usefulness has become a troubling issue of our age. To keep up with demand, manufacturers produce between 270 and 360 million Mg (300 and 400 million tons) of plastic worldwide each year.

When deemed useful, steel type, manufacturing method, thickness of plate, heat treatment, and other data are described.From toothbrush handles and computer keys to aviation components and medical devices, plastics have become an ubiquitous part of modern life. Mechanical properties (yield point, tensile strength, notch toughness).The following data is given for each standard. Steel Plates for Boiler and Pressure Vessels.These terms are defined as follows in the Regulations Governing ASTM Technical Committees. It contains formally approved ASTM standard classifications, guides, practices, specifications, test methods and terminology and related material such as proposals. The Annual Book of ASTM Standards for Steel consists of 8 volumes. They are integral components of today's competitive business strategies. The standards of ASTM International are used in research and development, quality systems, product testing and acceptance, and commercial transactions all around the globe. ASTM publishes a monthly magazine, Standardization News, which covers the topic of standards development around the world. ASTM's programs include symposia, proficiency testing programs, publications in a variety of formats, and technical training courses. In addition to this accommodating standards development atmosphere, ASTM International provides services that expand the knowledge and application of standards.

They include Internet-based Standards Development Forums enabling 24/7 access worldwide, on-line balloting, electronic minutes and templates, virtual meetings, and state-of-the- art distribution methods. To facilitate broad global input, ASTM International uses online technologies that encourage open participation and responsiveness to industry needs. With a high level of technical quality at the core of the ASTM standard, almost 50 percent of ASTM standards are distributed outside the United States. Professionals from all over the globe participate in the ASTM system which recognizes technical expertise, not country of origin. The open process in which ASTM standards are developed is one reason why so many and such a broad range of industries have done their diverse standards development work within ASTM International. These standards are used and accepted worldwide and cover areas such as metals, paints, plastics, textiles, petroleum, construction, energy, the environment, consumer products, medical services and devices, and electronics. Thirty thousand ASTM members from 125 countries bring their technical expertise to the development of ASTM's 12,000 international standards.
