ASTM E34 Chemical Analysis of Aluminum and Aluminum-Base Alloys

The chemical analysis of aluminum and aluminum-based alloys with a definite composition is covered in ASTM E34.

TRUSTED BY ENGINEERS FROM

Scope:

ASTM E34 is used for metals and alloys to ensure that the materials meet compositional standards. All users of these test methods are expected to be qualified analysts capable of completing conventional laboratory operations competently and safely. The job will most likely be done in a professionally equipped laboratory.

Test Procedure:

The analytical procedures appear in the following sections:

Test Method	Section
Beryllium by the morin (fluorometric) test method	8-19
Bismuth by the thiourea (photometric) test method	20-29
Boron by the carmine (photometric) test method	30-38
Chromium by the diphenylcarbazide (photometric) test method	39-47
Chromium by the persulfate oxidation (titrimetric) test method	48-53
Copper by the neocuproine (photometric) test method	54-63
Copper and lead by the electrolytic (gravimetric) test method	64-72
Iron by the 1,10-phenanthroline (photometric) test method	73-81
Iron by the 1,10-phenanthroline (photometric) test method	82-87
Magnesium by the ethylenediamine tetraacetate (titrimetric) test method	88-93
Manganese by the periodate (photometric) test method	94-102
Nickel by the dimethylglyoxime (photometric) test method	103-111
Nickel by the dimethylglyoxime (gravimetric) test method	112-117
Silicon by the molybdisilicic acid (photometric) test method	118-127
Silicon by the sodium hydroxide-Perchloric acid (gravimetric) test method	128-133

Specimen size:

The diameter of the drill bits should not be less than 0.95 cm (3⁄8 in.) and not larger than 1.27 cm (1⁄2 in.) in diameter for ASTM E34 testing.

Data

For ASTM E34, the percentage of each test method is calculated, and values are rounded to the necessary number of decimal places using the practice’s rounding procedure.

Conclusion:

ASTM E34 is used for metals and alloys to ensure that the materials meet compositional standards.
