ASTM B846 provides definitions for many terms used in the copper industry including the ASTM copper standards and specifications. From ASTM B846, “lot” and “heat” are defined as follows:
- Lot: A collection of like product (i.e. same alloy, temper, and dimensions) produced under uniform conditions from which a sample is to be drawn for inspection or testing, or both.
- Heat: A lot of cast product that shares, and can be identified by, a common chemical analysis result.
In essence, a lot could potentially include more than one heat but maintain its traceability as a lot. If lot or heat traceability is required, please inform your Customer Service Representative before the product is quoted.
