ASTM D20塑料技术委员会D20.95可回收塑料分技术委员会对D7611《树脂识别用塑料制品的编号的标准实施规程》进行了重大修订。D7611标准规程于2010年首次颁布,规定了可长期执行的树脂识别码(RIC)系统,以识别用于塑料制品中不同类型的塑料树脂。树脂识别码最初由塑料行业协会(SPI,美国)在1988年开发出来,这一适用于全世界的统一编码系统满足了生产商和回收企业的需要。2008年,塑料行业协会与ASTM国际标准组织合作,召集业界利
ASTM D20 Plastics Technical Committee D20.95 The Technical Committee on Recyclable Plastics has made significant revisions to D7611, “Standard Practice for Numbering of Plastic Products for Resin Identification.” The D7611 standard protocol, first introduced in 2010, provides a long-lasting Resin Identification Number (RIC) system to identify different types of plastic resins used in plastic products. Originally developed by the Plastics Industries Association (SPI, USA) in 1988, the Resin ID is a Universal Encoding System for the world that meets the needs of manufacturers and recyclers. In 2008, Plastics Industry Association and ASTM International Organization for Standardization, convened the industry Lee
