Foreword
This Standard revised and adopted ISO 11469.2000 “Plastics - Generic Identification
and Marking of Plastic Products”. The main differences between this Standard and
ISO 11469.2000 are. directly REFERENCE the corresponding national standards,
DELETE the definition associated with computer terminology given in the original
standard, REDEFINE the scope of this Standard, ADD requirements for material
identification and marking of automotive plastic, rubber and thermoplastic elastomer
parts.
This Standard was proposed by the National Technical Committee of Auto
Standardization.
This standard shall be under the jurisdiction of the National Technical Committee of
Auto Standardization.
Drafting organization of this Standard. Pan Asia Technical Automotive Center Co., Ltd.
Main drafter of this Standard. Li Minglin.
This Standard is issued for the first-time.
Material identification & marking of automotive plastic,
rubber & thermoplastic elastomer parts
1 Scope
This Standard specifies the requirements for material identification and marking of
automotive plastic, rubber and thermoplastic elastomer parts.
This Standard applies to material identification and marking of automotive plastic with
the mass exceeding 100 g, rubber with the mass exceeding 200 g and thermoplastic
elastomer parts, this Standard does not apply to identification and marking of
automotive tires. For the product with the mass lower than the value specified in this
Standard, this Standard can be referenced.
2 Normative references
The provisions in following documents become the provisions of this Standard through
reference in this Standard. For dated references, the subsequent amendments
(excluding corrigendum) or revisions do not apply to this Standard, however, parties
who reach an agreement based on this Standard are encouraged to study if the latest
versions of these documents are applicable. For undated references, the latest edition
of the referenced document applies.

Example. For a product made of three components, the visible one being a thin
coating of polyvinyl chloride (PVC) over a polyurethane foaming plastic (PUR)
containing an insert of acrylonitrile-butadiene-styrene (ABS) that is the major
components by mass, marked as.
> PVC, PUR, ABS <
5.1.5 Identification of rubber and thermoplastic elastomer products.
Identification of automotive rubber and thermoplastic elastomer products shall
emphasizes the primary material, and be marked according to the format specified in
5.1.1.
Example 1. For a product containing a mixture of natural rubber (NR) and styrene
butadiene rubber (SBR), marked as.
> NR + SBR <
Example 2. For fuel hose product externally coated with chloroprene rubber (CR) and
internally coated with acrylonitrile-butadiene rubber (NBR), the middle enhancement
line of which is not identified, marked as.
External layer > CR < internal layer > NBR < or > CR, NBR <
Example 3. For cooling circulating hose product internally coated with
ethylene-propylene-diene monomer rubber (EPDM) (primary composition) and
externally coated with chlorosulphonated polyethylene (CSM), marked as.
Internal layer > EPDM < external layer > CSM < or > EPDM, CSM <
Example 4. For automotive steering knuckle shield for dust prevention made of
thermoplastic polyester elastomer material (TPC), marked as.
> TPC <
Example 5. For automotive bumper made of thermoplastic polyolefin elastomer
material (TPO), marked as.
> TPO <
5.2 Identification methods
The identification of plastic, rubber and thermoplastic elastomer parts shall be made
by one of the following methods.
a) by using the appropriate symbol molding during mold design;
b) by embossing and by melt imprinting of the polymer;
