Prøvemassen

Prøvemassen (the test mass) is a term used in Norwegian and Danish contexts to denote the portion of material selected from a larger batch for laboratory testing, quality control, or product specification checks. The purpose is to obtain analytical results that are representative of the entire batch while enabling efficient testing. The size and composition of the prøvemassen are determined by a sampling plan that accounts for batch size, material heterogeneity, intended analyses, and the required level of statistical confidence. The mass is measured with calibrated balances, and results are reported with traceable uncertainty.

Handling and preparation: The prøvemassen should be representative of the material as delivered. It may be subdivided into primary and secondary samples, and may require homogenization, size reduction, drying, or moisture determination. Containers should be clean, labeled, and sealed to maintain traceability. The sample should be transported under appropriate conditions and stored to minimize changes before analysis.

Quality and standards: Testing laboratories follow national and international standards for sampling procedures, mass requirements, and documentation. Chain of custody, proper labeling, calibration records, and traceability are essential. Applications span industries such as mining, construction, food, pharmaceuticals, and environmental testing, where prøvemassen forms the basis for compliance and quality control.
