ASTM D632-01

Standard Specification for Sodium Chloride (Withdrawn 2010)

ABSTRACT
This specification covers testing and property requirements of two types and two grades of sodium chloride obtained from natural deposits (rock salt) or produced by man (evaporated, solar, and others), intended for use as a deicer and for road construction or maintenance purposes. Type I is used primarily as a pavement deicer or in aggregate stabilization. This type is further subdivided into Grade 1 (standard grading) and Grade 2 (special grading). Type II, is used in aggregate stabilization or for purposes other than deicing. The sodium chloride shall be sampled, tested, and conform to chemical and physical requirements discussed herein.
SCOPE
1.1 This specification covers sodium chloride intended for use as a deicer and for road construction or maintenance purposes.
1.2 The values stated as SI units are to be regarded as the standard.
1.3 For purposes of determining conformance to this specification, values for chemical analysis shall be rounded to the nearest 0.1 %, and values for grading shall be rounded to the nearest 1 %, in accordance with the rounding method in Practice E29.
1.4 The text of this specification references notes and footnotes that provide explanatory material. These notes and footnotes shall not be considered as requirements of the specification.
1.5 The following precautionary caveat pertains only to the test method in Annex A1, of this specification: 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.
WITHDRAWN RATIONALE
This specification covers sodium chloride intended for use as a deicer and for road construction or maintenance purposes.
Formerly under the jurisdiction of Committee D04 on Road and Paving Materials, this specification was withdrawn in February 2010 in accordance with section 10.5.3.1 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.
