ASTM D1203-22

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D1203 − 21 D1203 − 22
Standard Test Methods for
Volatile Loss from Plastics Using Activated Carbon
1
Methods
This standard is issued under the fixed designation D1203; 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 (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*
1.1 These test methods cover the determination of volatile loss from a plastic material under defined conditions of time and
temperature, using activated carbon as the immersion medium.
1.2 Two test methods are covered as follows:
1.2.1 Test Method A, Direct Contact with Activated Carbon—In this test method the plastic material is in direct contact with the
carbon. This test method is particularly useful in the rapid comparison of a large number of plastic specimens.
1.2.2 Test Method B, Wire Cage—This test method prescribes the use of a wire cage, which prevents direct contact between the
plastic material and the carbon. By eliminating the direct contact, the migration of the volatile components to the surrounding
carbon is minimized and loss by volatilization is more specifically measured.
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, health, and environmental practices and determine the applicability of
regulatory limitations prior to use.
NOTE 1—This standard and ISO 176 address the same subject matter, but differ in technical content.
1.5 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4. Significance and Use
4.1 The test methods are intended to be rapid empirical tests which have been found to be useful in the relative comparison of
materials having the same nominal thickness.
NOTE 2—When the plastic material contains plasticizer, loss from the plastic is assumed to be primarily plasticizer. The effect of moisture is considered
to be negligible.
