(Classification)Standard Classification for Thermoplastic Elastomers-Olefinic (TEO) (Withdrawn 2005)
Standard Classification for Thermoplastic Elastomers-Olefinic (TEO) (Withdrawn 2005)
SCOPE
1.1 This classification covers olefinic thermoplastic elastomers (TEOs) made directly in a reactor or through a compounding process and suitable for injection molding, extrusion, blow molding, or other melt processing. Compounding ingredients may be present as necessary for the applications and may consist of reinforcements, fillers, stabilizers, colorants, and other ingredients.
1.2 This classification allows for the use of those TEO materials, which can be recycled, reground, and reprocessed, provided that the requirements as stated in this classification are met. The proportions of recycled material used, as well as the nature and the amount of any contaminant, however, cannot be practically covered in this classification.
1.3 The properties included in this classification are those required to identify the compositions for most applications. Other requirements may be necessary to further identify particular characteristics. These may be specified by using the suffixes in accordance with Section 5.
1.4 The values stated in SI units are to be regarded as the standard. The inch-pound units are for information only.
1.5 The following precautionary caveat pertains only to the test method portion, Section 11, of this classification: 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 1-There is no similar or equivalent ISO standard.
WITHDRAWN RATIONALE
This classification covers olefinic thermoplastic elastomers (TEOs) made directly in a reactor or through a compounding process and suitable for injection molding, extrusion, blow molding, or other melt processing. Compounding ingredients may be present as necessary for the applications and may consist of reinforcements, fillers, stabilizers, colorants, and other ingredients.
Formerly under the jurisdiction of Committee D20 on Plastics, this classification was withdrawn in July 2005 due to its limited use by industry.

Designation: D 5593 – 99
Standard Classification for
Thermoplastic Elastomers—Olefinic (TEO)
This standard is issued under the fixed designation D 5593; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
e NOTE—Editorially corrected the description for Group 02, Class 1 in Table TEO in April 2002.
INTRODUCTION
This classification is intended to be a system for calling out olefinic thermoplastic elastomers used
in the fabrication of end items or parts. It is not intended for the selection of materials. Material
selection should be made by those having expertise in the plastics field after careful consideration of
the design and the performance required of the part, the environment to which it will be exposed, the
fabrication processes to be employed, and the inherent properties of the material other than those
covered by this classification.
