The "labeling" or tagging of samples during the sampling of bulk materials is an essential part of the process and serves several purposes:

  1. Identification: Labels allow for the unique identification of each sample. They can contain information such as the name or type of material, the location and date of sampling, the name of the sampler, and other relevant details.
  2. Traceability: By recording the above-mentioned information on the label, each sample can be traced back. This means that one can precisely know when and where the sample was taken and who collected it. This is particularly important when the analysis results need to be reviewed or challenged at a later stage.
  3. Organization and Management: Labeled samples are easier to organize and manage, especially when large quantities of samples are taken and analyzed. The labels can help keep the samples in the correct order and prevent samples from being mixed up or lost.
  4. Safety and Compliance: In some cases, labels can also contain safety information, such as whether the material is hazardous and how it should be handled safely. They can also help ensure compliance with regulations and standards by documenting that the sampling was carried out properly.

The use of a standardized labeling system is a proven element of good practice in the sampling and analysis of bulk materials. It helps ensure the quality and reliability of the data and contributes to the efficiency and safety of the process.
