1.1 These test methods cover the chemical analyses usually required for sodium chloride.
1.2 The analytical procedures appear in the following sections:
| Section | |
| Sample Preparation | 5 to 9 |
| Moisture | 10 to 16 |
| Water Insolubles | 17 to 24 |
| Calcium and Magnesium | 25 to 31 |
| Sulfate | 32 to 38 |
| Reporting of Analyses | 39 to 41 |
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 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.
1.5 Review the current material safety data sheets (MSDS) for detailed information concerning toxicity, first-aid procedures, handling, and safety precautions.
5.1 This test method covers preparation of a sample that will be as representative as possible of the entire bulk quantity. The results of any analysis pertain only to the sample used.
10.1 This test method determines free moisture in the salt over a concentration range from 0.00 to 0.04 %. It does not determine occluded moisture trapped within the salt crystals. The procedure is based on weight loss after a sample is heated to volatize moisture.
17.1 This gravimetric method determines only the amount of insolubles present in sodium chloride which will not dissolve in water.
25.1 This test method covers the EDTA titrimetric determination of calcium and magnesium and the EDTA titrimetric determination of calcium. The magnesium content is determined by difference.
32.1 This test method covers the gravimetric determination of the sulfate content of sodium chloride.
39.1 Analyses should be reported on a dry basis. If analyses are on an as received sample, correction should be made by converting to a dry basis. Sodium chloride purity is determined by subtracting the total percentage of impurities from 100. Moisture should be reported as a separate value.
