Oilseeds - Reduction of laboratory sample to test sample (ISO 664:2008)

This standard outlines the standardized procedures for reducing laboratory samples of oilseed crops into test samples suitable for analysis. It establishes a systematic approach to ensure sample representativeness while maintaining consistency and reproducibility across different testing environments. The methodology covers the step-by-step process of sample division, including equipment requirements, operational techniques, and measures to prevent contamination or alteration of the sample's original characteristics. By adhering to these guidelines, laboratories can achieve accurate and reliable results when evaluating oilseed quality. The procedure is designed to be applicable to various types of oil-bearing seeds and is widely recognized for its effectiveness in minimizing sampling errors. It provides clear instructions on how to handle samples from the point of receipt through to the final test portion, ensuring that the analytical outcomes reflect the true nature of the material being assessed. This framework supports quality assurance protocols in the agricultural and food industries by providing a uniform method for sample preparation.
