Scope

1.1 This test method covers the Wijs procedure for determination of unsaturation (iodine value) in drying oils. It is applicable to all natural and synthetic drying oils and their fatty acids.

1.2 When the iodine value is determined on oils or fatty acids having conjugated systems, the result is not a measure of total unsaturation, but rather is an empirical value that affords a comparison of total unsaturation.

1.3 To obtain the total iodine value on conjugated samples, use Test Method D 1541.

Note 1-This test method is essentially equivalent to Test Methods D 2075 and D 2078.

1.4 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety problems 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.> For specific hazard statements, see Section 8.
