Iron, %	0.002 to 0.1
Lead, %	0.001 to 0.5
Manganese, %	0.01 to 2.0
Nickel, %	0.0005 to 0.5
Rare earth elements, %	0.2 to 10
Silicon, %	0.01 to 0.8
Thorium, %	0.2 to 25
Tin, %	0.5 to 10
Zinc, %	0.3 to 20
Zirconium, %	0.03 to 1.0
Magnesium, %	remainder

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials; these test methods were withdrawn in September 2008. This standard was withdrawn with no replacement because it does not contain bias or precision data for any of the test methods and this information is now required to be included.

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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautions are given in Section 5.
