ASTM D1972-97(2001)

Standard Practice for Generic Marking of Plastic Products

SCOPE
1.1 This practice covers a system for uniform marking of products that have been fabricated from polymeric materials. Provision for the process or processes to be used for marking is outside the scope of this practice.
Note 1--Precise details of the marking, for example, the minimum size of the item to be marked, the size of the lettering, and the appropriate location of the marking, may be the subject to agreement between the manufacturer and the user.
1.2 The abbreviated terms used are to provide generic identification of the polymer(s).
1.3 This practice is especially pertinent for use with durable plastic components of products. This practice is not intended to supplant, replace, or in any way interfere with the requirements found in legislation for marking or labeling of packaging.
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.
Note 2--In many respects, this practice is similar to ISO 11469.
