ASTM B 1028 : 2024

1.1This document is a guide for the use of portable hand held XRF analyzers for the determination of chemistry, quality, or grading of scrap copper and copper-based alloys.

1.2This guide is intended to be applied to all appropriate technologies discussed herein, and for all purposes described herein, where such purposes can be achieved or addressed suitably by the specific technology or method.

1.3This guide does not by omission recommend against the use of other methods, devices, or equipment to evaluate copper-bearing materials outside of this scope, such as hand held magnets, spark testing, LIBS technology, Optical Emission Spectroscopy (whether portable or stationary) or stationary equipment such as ICPs, or spark AES. Further, this guide does not presume that hand held XRF devices will be the only means of evaluation deployed for a given sample, lot, or occasion.

1.4Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.

1.5This 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.

1.6This 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.
