1.1 This guide covers the procedures of acquiring a representative sample of copper and copper alloy scrap in the form of small particles for analysis. This method is for (but not limited to) determining the chemical composition using Atomic Emission Spectroscopy (AES), but other methods of tests may also be used depending on laboratory sample preparation. This guide addresses a composite analysis of the lot examined by the user.

1.2 This guide is also intended to be adaptable and work with different techniques that might be appropriate for different situations based on how copper and copper alloy scrap particles are collected and how the product is delivered.

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.4 This 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.

4.1 This guide is intended primarily for the sampling of particulated copper and copper alloy material for compliance with compositional specification requirements. “Granulated chops” commonly refers to wire and cable, but it may also include other forms and applications of copper such as, but not limited to, transformer windings, plumbing tube, radiators, and sheet. This guide also applies to lots of material that are already particulated in the as-received condition, that is, not subjected to mechanical processing such as turnings, shavings, dust, and fines.

4.2 Particles ³/₄ in. and down in their largest dimension are recommended for sampling as “chops” or “particulates” in accordance with this guide. Larger particles may lend themselves to other methods of inspection, including visual, at the discretion of the user.

4.3 As-received particulated material packaging may vary as a function of the shippers’ and receivers’ capabilities. In areas of confinement, gaylord or container boxes are commonly used, but some shipments can be loose and unpackaged that can be dumped onto the floor for inspection.

4.4 Various physical sampling techniques are applicable: for example, shoveling to fill a bucket, or use of a pipe sampler or auger to obtain a core sample, representative of a full height sample of the cross-section of scrap in accordance with Practices B215. Tools described and depicted in Practices B215, and applicable here (but not limited to), include:

4.5 Users are encouraged to read Practices B215 Section 5 “Apparatus” for descriptions of equipment that may be applicable to sampling particulated copper material.

4.6 Pneumatic aspirators may also be employed to gather samples, as shown in Fig. 2 below.
