| Sulfur by the Combustion-Infrared Absorption Method (Potassium Sulfate Calibration) | 20-30 |
1.3This 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. Specific hazards statements are given in Section 5.
