ASTM D5021-00

Standard Specification for Thermoplastic Elastomer-Chlorinated Ethylene Alloy (TECEA) (Withdrawn 2007)

SCOPE
1.1 This specification covers alloys of chlorinated ethylene elastomers suitable for injection molding, extrusion, blow molding, thermoforming, and other plastics processing methods.
1.2 This specification allows for the use of those TECEA materials that can be recycled, regrounded, and reprocessed, provided that the requirements as stated in this specification are met. The proportions of recycled material used, as well as the nature and amount of any contaminant, however, cannot be covered practically in this specification.
1.3 The properties included in this specification are those required to identify the compositions covered. There may be other requirements necessary to identify particular characteristics important to specialized application. These shall be agreed upon between the user and the supplier, by using the suffixes given in Section 5.
1.4 The values stated in SI units are to be regarded as the standard. The practices, as detailed in Practice IEEE/ASTM SI 10, are incorporated herein.
1.5 The following precautionary caveat pertains only to the test methods portion, Section 10, of this specification:  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WITHDRAWN RATIONALE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 specification covered alloys of chlorinated ethylene elastomers suitable for injection molding, extrusion, blow molding, thermoforming, and other plastics processing methods. Formerly under the jurisdiction of Committee D20 on Plastics, this specification was withdrawn in September 2007. This standard is being withdrawn without replacement due to its limited use by industry.

Standard Specification for
Thermoplastic Elastomer–Chlorinated Ethylene Alloy
(TECEA)
This standard is issued under the fixed designation D 5021; 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.
INTRODUCTION
This specification is intended to be a means of calling out materials 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 process
to be employed, the inherent properties of the materials other than those covered by this specification,
and the economics.
