【国外标准】 Standard Test Methods for Chemical Analysis of Aluminum and Aluminum-Base Alloys (Withdrawn 2017)

These test methods for the chemical analysis of metals and alloys are primarily intended to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.Note—Shaded areas are suitable for sampling.FIG. 1 Type A and Type B Disks1.1 These test methods cover the chemical analysis of aluminum and aluminum-base alloys having compositions within the following limits:Beryllium, ppm 0.3 to 100Bismuth, % 0.02 to 1.0Boron, % 0.005 to 0.060Cadmium, % 0.001 to 0.50Chromium, % 0.01 to 1.0Copper, % 0.01 to 20.0Gallium, % 0.001 to 0.05Iron, % 0.01 to 3.0Lead, % 0.01 to 1.0Lithium, % 0.001 to 4.0Magnesium, % 0.002 to 12.0Manganese, % 0.005 to 2.0Nickel, % 0.01 to 4.0Silicon, % 0.05 to 20.0Tin, % 0.03 to 1.0Titanium, % 0.002 to 0.30Vanadium, % 0.002 to 0.16Zinc, % 0.003 to 12.0Zirconium, % 0.01 to 0.301.2 The analytical procedures appear in the following sections:Procedure SectionsBeryllium: Beryllium by Argon Plasma Optical EmissionSpectroscopy 283 to 292Beryllium by the Morin (Fluorometric) TestMethod 1eBismuth: Bismuth by the Thiourea (Photometric) Method 1aBismuth and Lead by the Atomic AbsorptionTest Method 188 to 198Boron: Boron by the Carmine (Photometric) Test Method 1eCadmium: Cadmium by the Atomic Absorption Test Method 167 to 177Chromium: Chromium by the Diphenylcarbazide (Photometric)Test Method 1eChromium by the Persulfate Oxidation (Titrimetric)Test Method 1bChromium by the Atomic Absorption Test Method 199 to 209Copper: Copper and Lead by the Electrolytic (Gravimetric)Test Method 1cCopper and Zinc by the Atomic AbsorptionSpectometry Test Method 210 to 220Copper by the Electrolytic (Gravimetric) Test Method 303 to 311Copper by the Neocuproine (Photometric)Test Method 1aGallium: Gallium by the Ion Exchange-Atomic AbsorptionTest Method 312 to 323Iron: Iron by the 1,10-Phenanthroline (Photometric) Method 73 to 81Iron and Manganese by the Atomic AbsorptionSpectometry Method 221 to 231Lead: Copper and Lead by the Electrolytic (Gravimetric)Test Method 1 cBismuth and Lead by the Atomic AbsorptionSpectrometry Test Method 188 to 198Lithium: Lithium by the Atomic Absorption Test Method 324 to 334Magnesium: Magnesium by the Pyrophosphate (Gravimetric)Method 1 bMagnesium by the Ethylenediamine Tetraacetate(Titrimetric) Test Method 1 eMagnesium by the Atomic Absorption SpectrometryTest Method 232 to 242Manganese: Iron and Manganese by the Atomic AbsorptionSpectrometry Test Method 221 to 231Manganese by the Periodate (Photometric)Test Method 293 to 302Nickel: Nickel by the Dimethylglyoxime (Photometric)Test Method 1aNickel by the Dimethylglyoxime (Gravimetric)Test Method 1bNickel by the Atomic Absorption SpectrometryTest Method 243 to 253Silicon: Silicon by the Molybdisilicic Acid (Photometric)Test Method 1 eSilicon by the Sodium Hydroxide-Perchloric Acid(Gravimetric) Method 1 eTin: Tin by the Iodate (Titrimetric) Test Method 1 eTitanium: Titanium by the Chromotropic Acid (Photometric)Test Method 141 to 150Titanium by the Diantipyrylmethane PhotometricTest Method 254 to 263Vanadium: Vanadium by an Extraction-Photometric Test Methodusing N-Benzoyl-N-Phenylhydroxylamine 264 to 273Zinc: Zinc by the Ammonium Mercuric Thiocyanate or theZinc Oxide (Gravimetric) Test Method 1bZinc by the Ethylenediamine Tetraacetate(Titrimetric) Test Method 1dCopper and Zinc by the Atomic AbsorptionSpectrometry Test Method 210 to 220Zinc by the Ion Exchange-EDTA TitrimetricTest Method 274 to 282Zirconium: Zirconium by the Arsenazo III (Photometric) Method 178 to 1871.3 The values stated in SI units are to be regarded as the standard.1.4 This standard does not purport to address all of the safety problems, 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 hazard statements are given throughout these test methods.
