The full processes for sampling copper, lead, zinc, and nickel concentrations are outlined in the ISO 12743:2021 standard. This standard's primary goal is to collect representative samples from stationary lots and moving streams for use in chemical analysis, physical testing, and moisture content determination.
The sampling frame is a list of items from which the sample is drawn. For research, a frame of the population is to be constructed which will enable the researcher to draw the sample, e.g., names from the census records or telephone directory, etc., for conducting a study on a sample that is drawn from the frame.
