8、ISO 11469:1993 Plastics Generic identification and marking of plastic products, published by the International Organization for Standardization (ISO). The Technical Committee has reviewed the provisions of ISO 472:1988 and ISO 1087:1990 to which normative reference is made in the text, and has decid
9、ed that they are acceptable for use in conjunction with this standard. A related British Standard to ISO 1043-2:1988 is BS 3502 Symbols for plastics and rubber materials Part 3:1993 Schedule for symbols for compounding ingredients. A British Standard does not purport to include all the necessary pro
10、visions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

13、Standard specifies a system for the uniform marking of products that have been fabricated from plastic materials. Provision for the process or processes to be used for marking is outside the scope of this International Standard. NOTE 1Precise details of the marking, e.g. the minimum size of the item
14、 to be marked, the size of the lettering, the appropriate location of the marking, may be subject to agreement between the manufacturer and the user. 1.2 The marking system should help identify plastic products for subsequent decisions relating to handling, waste recovery or disposal. 1.3 The symbol
15、s and abbreviated terms used are intended to provide generic identification of the plastics. 1.4 This International Standard is not intended to supplant, replace, or in any way to interfere with requirements for labelling found in legislation. 2 Normative references The following standards contain p
