1.1 These test methods cover the chemical analyses of acid-grade calcium fluoride (fluorspar). These test methods appear in the following sections:
| Sections | |
| Volatiles as Moisture | 6-13 |
| Silica | 14-22 |
| Assay as Calcium Fluoride (CaF 2) | 23-32 |
| Soluble Chloride as NaC1 | 33-50 |
| Calcium Carbonate | 51-59 |
| Phosphorus | 60-69 |
| Arsenic | 70-78 |
| Mixed Oxides (R2O3) | 79-87 |
| Sulfide Sulfur | 88-96 |
1.2 The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.3 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.
1.4 Review the current Material Safety Data Sheet (MSDS) for each chemical used in this standard for detailed information concerning toxicity, first-aid procedures, handling, and safety precautions.
6.1 This test method covers the determination of volatiles as percent moisture.
14.1 This test method covers the determination of percent silica.
23.1 This test method covers the determination of assay as percent calcium fluoride (CaF2).
51.1 This test method covers the determination of calcium carbonate in the range from 0 to 2 %.
60.1 This test method covers the determination of total phosphorus.
70.1 This test method covers the determination of total arsenic.
79.1 This test method covers the determination of percent mixed oxides (R2O3).
88.1 This test method covers the determination of sulfide sulfur in the range from 0.001 to 0.2 %.
