CONTAINED IN VOL. 06.03, 2017 Defines the Wijs procedure for determination of unsaturation (iodine value) of tall oil fatty acids.

1.1This test method covers the Wijs procedure for determination of unsaturation (iodine value) of tall oil fatty acids.

1.2Iodine value is a measure of the unsaturation of oils and fatty acids and is expressed in terms of the number of centigrams of iodine per gram of sample (weight percent of absorbed iodine).

1.3When this test method is used to determine the iodine value of fatty acids having conjugated systems, the result is not a measure of total unsaturated, but rather is an empirical value that affords a comparison of unsaturation. Total unsaturation of conjugated systems may be measured in accordance with Test Method D1541.

1.4The test method described here is not reliable for tall oil fatty acids containing an appreciable quantity of rosin.

1.5The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6This 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.
