Standard Test Method for Determination of Phosphorus in Nickel, Ferronickel, and Nickel Alloys by Phosphovanadomolybdate Spectrophotometry
| 분야 | 03.05 : 금속, 광석 및 관련 재료의 분석화학 |
|---|---|
| 적용범위 | 1.1 This test method covers the determination of phosphorus in nickel, ferronickel, and nickel alloys in the range 0.0007 % to 0.05 %. 1.2 Arsenic, chromium, hafnium, niobium, silicon, tantalum, titanium, and tungsten interfere, but the interference can be avoided by complexation or volatilization (for chromium). The lowest phosphorus content (0.0007 %) can be reached only in samples with low contents of interfering elements. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazards associated with the use of this test method see Practices E50. Refer to specific warning notes given throughout this test method. 1.5 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. |
