Scope
1.1 This test method covers the determination of the spectrophotometric diene value as a measure of the content of conjugated dienoic acids in dehydrated castor oil and its derivatives. Due to the high linoleic acid content in dehydrated castor oil and its derivatives, the absolute conjugated dienoic acid content cannot be determined by this test method.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 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. Specific hazard statements are given in Section 6.
