1. Scope
1.1 This practice stipulates the types, names and sizes of codes for those material types specified in Table 1. 1.2 The use of an identification code does not in itself, imply that there are existing systems in place to effectively process the recycled goods for reclamation or re-use. 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 1.5 There is currently no ISO equivalent document.
This practice is based upon the original system developed in 1988 by the Society of the Plastics Industry, Inc (SPI) which offered a means of identifying the resin content of bottles and rigid containers commonly found in the residential waste stream. Currently 39 States have adopted legislation regarding the use of resin identification codes consistent with the SPI code. It also is in use in China, and the U. K. and is now recommended by the British Plastics Federation and PlasticsEurope (formerly the Association of Plastics Manufacturers in Europe). While originally intended to facilitate recycling of post-consumer plastic bottles and rigid containers, its use has expanded, and now potentially covers packaging films and finished products that are reusable and/or recyclable.
