ASTM D 1972 Document Information:
Title
Standard Practice for Generic Marking of Plastic Products
ASTM International
Publication Date:
Apr 10, 1997
Scope:
(Footnote *)
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 subject to agreement
between the manufacturer and the user.
The abbreviated terms used are to provide generic identification of
the polymer(s).
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.
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.
Footnote * - A Summary of Changes section appears at the end of this
standard.
