sample, taken in a single operation at a single place and time Note 1 to entry: If it can be assumed that the material is homogeneous, a spot sample is regarded as a representative
sample. If the material is not homogeneous, a spot sample is only regarded as representative of a limited region around the sampling point. en at a specific depth in a stationary material, usually in order to detect segregation in large storage containers.BS EN 58 pdf download.
