AS 2862.1:2021

Full Description

This document identically adopts ISO 12743:2021 which sets out the basic methods for sampling copper, lead, zinc and nickel concentrates from moving streams and stationary lots, including stopped-belt sampling, to provide samples for chemical analysis, physical testing and determination of moisture content, in accordance with the relevant International Standards. Where the concentrates are susceptible to significant oxidation or decomposition, a common and sufficiently precise sample is used for moisture determination and chemical analysis to eliminate bias (see AS 2863).
