Organization: ASTM International
Publication Date: 10 July 1997
Status: inactive
Page Count: 5
ICS Code (Chemical analysis): 71.040.40
scope:

1.1 This test method covers the determination of hydroxyl groups attached to primary and secondary carbon atoms in aliphatic and cyclic compounds and phenols. It is not suitable for determination of hydroxyl groups attached to tertiary carbon atoms. This test method is applicable to polyacetals, temperature sensitive materials, high solids polymer polyols, and rigid polyols. Other availalbe test methods listed in Note 1 are not suitable for many of the sample types listed above.

1.1.1 This test method is currently recommended for neutral refined products. Successful application has been made, however, to some in-process samples that contain an excess of acidic species. Proper validation must be performed, of course, to show that the acidic species either does not interfere, or that the acidic species interference has been obviated.

Note 1--Other methods for determination of hydroxyl groups are given in test Methods D817, D871, D1957, D2195, D4252, D4273, D4274, E222, E326, and E335.

1.2 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 standrd to establish appropriate safety and health practices an determine the applicability of regulatory limitaitons prior to use.

1.3 Revew the current appropriate Material Safety Data Sheets (MSDS) for detailed informaiton concerning toxicity, first aid procedures, and safety precautions.
