    1. Scope

    1.1 This specification covers refined indium as ingot in six grades as follows:

    1.1.1 Grade 99.9—Indium having a purity of 99.90 %, also known as 3N grade,

    1.1.2 Grade 99.99—Indium having a purity of 99.99 %, also known as 4N grade,

    1.1.3 Grade 99.995—Indium having a purity of 99.995 %, also known as 4N5 grade,

    1.1.4 Grade 99.999—Indium having a purity of 99.999 %, also known as 5N grade,

    1.1.5 Grade 99.9999—Indium having a purity of 99.9999 %, also known as 6N grade, and

    1.1.6 Grade 99.99995—Indium having a purity of 99.99995 %, also known as 6N5 grade.

    1.2 Indium metal from ingot can be fabricated into shot, spheres, wire, sheet, foil, tubing, and other customized fabrications with purities up to and including Grade 99.999. Grades 99.9999 and 99.99995 are available in ingot form only.

    1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use.
