(Specification)Standard Specification for Calcium Chloride
Standard Specification for Calcium Chloride
ABSTRACT
This specification covers technical grade calcium chloride typically used for, but not limited to, dust control, stabilization, ice/snow removal, other road-conditioning purposes, acceleration of the set of concrete, and as a desiccant. Two types of calcium chloride are covered, as follows: Type S (solid), flake, pellet, or granular calcium chloride in varying concentrations; and Type L (liquid), water solutions of calcium chloride in varying concentrations. Concentrations shall be expressed as a percentage of the total. Impurities such as alkali chlorides, magnesium, and calcium hydroxide should be within specified composition limits.
SCOPE
1.1 This specification covers calcium chloride, technical grade, typically used for, but not limited to, dust control, stabilization, ice/snow removal, other road-conditioning purposes, acceleration of the set of concrete, and as a desiccant.
1.2 The values stated in 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 standard references notes and footnotes, which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
