The Appendix describes a rapid method for the chemical analysis to determine total chlorides of the calcium chloride sample.

SI Units-The values stated in SI units are to be regarded as the standard. The inch-pound equivalents may be approximate. It is common practice in the engineering profession to concurrently use pounds to represent both a unit of mass (lbm) and of force (lbf).

In the English system, the pound (lbf) represents a unit of force (weight). However, the use of balances or scales recording pounds of mass (lbm) should not be regarded as nonconformance with this standard.
