ASTM D1614-09(2017)

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation: D1614 − 09 D1614 − 09 (Reapproved 2017)
Standard Test Method for
Alkalinity in Acetone
This standard is issued under the fixed designation D1614; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the U.S. Department of Defense.
1. Scope*Scope
1.1 This test method covers the determination in acetone of alkalinity calculated as ammonia (NH ).
1.2 The following applies to all specified limits in this standard; 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
the specification limit, in accordance with the rounding-off method of Practice E29.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 For specific hazard information and guidance, consult the supplier’s Material supplier’s Safety Data Sheet.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of whoever uses the user of this standard to consult and establish appropriate safety safety, health, and healthenvironmental
practices and determine the applicability of regulatory limitations prior to use. Specific hazard statements are given in Section 7.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization
established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued
by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3. Summary of Test Method
3.1 The specimen is added to water previously neutralized to the methyl red end point. If alkalinity is detected, it is titrated with
0.05 N H SO and reported as weight percent of NH .

such specifications are available. Other grades may be used, provided it is first ascertained that the reagent is of sufficiently high
purity to permit its use without lessening the accuracy of the determination.
6.2 Purity of Water—Unless otherwise indicated, references to water shall be understood to mean reagent water conforming to
Type IV or higher purity of Specification D1193.
6.3 Methyl Red Indicator Solution (1 g/L)—Dissolve 0.1 g of methyl red in 100 mL of methanol, ethanol, or isopropanol.
Prepare a fresh solution at least once a month as needed.
