Terminology3.1 Definitions:3.1.1 Resin Identification Code (RIC;
6、 Code)a molded, imprinted or raised symbol or wording that consists of an equilateraltriangle comprised of clockwise chasing arrows, triangle, a Resin Identification Number, and an Abbreviated Term for polymericmaterial in compliance with Fig. 1 and Table 1.4. Significance and Use4.1 Resin Identific
7、ation Codes are used solely to identify the plastic resin used in a manufactured article.4.2 Resin Identification Codes are not “recycle codes.” The use of a Resin Identification Code on a manufactured plastic articledoes not imply that the article is recycled or that there are systems in place to e
8、ffectively process the article for reclamation orre-use. The term “recyclable” or other environmental claims shall not be placed in proximity to the Code.4.3 This practice is based upon the system developed in 1988 by the Society of the Plastics Industry, Inc (SPI). It is possiblethat some states or
9、 countries will have incorporated the original SPI practice into statute or regulation. In those situations, thatstatute or regulation takes precedence over this standard.4.4 This practice shall only apply to new tooling. Existing molds that already incorporate older versions of the SPI RIC maybe mo
