Standard Test Method for Color of Cresylic Acids ("C" Series Standards) (Withdrawn 2005)
SCOPE
1.1 This test method covers the determination of the color of cresylic acids. The material under test is compared to arbitrary color standards that are expressed in terms of the "C" series color standards.
1.2 The following applies to all specified limits in this test method for purposes of determining conformance with this standard. An observed value or a calculated value shall be rounded off "to the nearest unit" in the last right hand digit used in expressing limit, in accordance with the rounding off method of Practice E29.
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. For specific hazard statements, see Section 6.
WITHDRAWN RATIONALE
This test method covers the determination of the color of cresylic acids. The material under test is compared to arbitrary color standards that are expressed in terms of the "C" series color standards.
Formerly under the jurisdiction of Committee D16 on Aromatic Hydrocarbons and Related Chemicals, this test method was withdrawn in July 2005. This standard is being withdrawn because the method is no longer used.
