Scope

1.1 This test method covers the determination of the relative volatility of plasticizers, or volatile contaminants, or both, at elevated temperatures.

1.2 The text of this test method references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this test method.

1.3 The values stated in SI units are to be regarded as the standard.

1.4 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 are no ISO standards covering the primary subject of this test method.

Significance and Use

The quantity of volatile components in a plasticizer has influence on fuming during processing, and the retention of flexibility and other properties in the end product (see 5.2). This test method may be used to measure the volatile components under closely controlled conditions.

Results obtained by this test method are not strictly equivalent to those obtained during processing where conditions of temperature and air flow are quite different.

Volatility is dependent upon air flow and temperature. Due to the difficulty of controlling air flow, results may vary widely between ovens. Therefore, control plasticizers shall be run simultaneously when making close comparisons.
