ASTM E316-17 PDF

Scope: 1.1 This test method covers the determination of iron in manganese ore in the range from 2 % to 20 %. NOTE 1—As used in this test method (except as related to the term relative standard deviation), “percent” or “%” refers to mass fraction (wt/wt) of the form 1g/100g. 1.2 The values stated in SI units are to be regarded as 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
