Description

Sets out methods for checking mechanical sampling systems for bias, covering primary sampling of particulate materials and subsequent sample preparation, whether manual methods or mechanical devices are employed.

Scope

This Guide sets out methods for checking mechanical sampling systems for bias. It covers primary sampling of particulate materials and subsequent sample preparation, whether manual methods or mechanical devices are employed. Bias testing involves an initial system check, comparison of routine sampling with a reference method, and ongoing system checks to confirm conformance. This is referred to as testing ‘relative bias’ if there is not a strong reason for expecting the alternative set of sampling procedures to be much more reliable than the routine sampling procedures.
