【国外标准】 Standard Classification for Thermoplastic Elastomers-Olefinic (TEO) (Withdrawn 2005)

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.
