BS ISO 11794:2017 sets out the basic methods for sampling particulate material that is mixed with a liquid,
usually water, to form a slurry. In industry and in the mining and mineral processing literature, slurry is
also referred to as pulp, but this term is not used in this document. At very high ratios of fine particulate
solids to liquids where material assumes a soft plastic form, the mixture is correctly termed as a paste.
Sampling of pastes is not covered in this document.
The procedures described in this document apply to sampling of particulate materials that are
transported in moving streams as slurries, but not pressurized slurries. These streams may fall freely
or be confined in pipes, launders, flumes, sluices, spirals or similar channels. Sampling of slurries in
stationary situations, such as a settled or even a well-stirred slurry in a holding vessel or dam, is not
recommended and is not covered in this document.
This document describes procedures that are designed to provide samples representative of the slurry
solids and particle-size distribution of the slurry under examination. After draining the slurry sample of
fluid and measuring the fluid volume, damp samples of the contained particulate material in the slurry
are available for drying (if required) and measurement of one or more characteristics in an unbiased
manner and with a known degree of precision. The characteristics are measured by chemical analysis,
physical testing or both.
The sampling methods described are applicable to slurries that require inspection to verify compliance
with product specifications, determination of the value of a characteristic as a basis for settlement
between trading partners or estimation of a set of average characteristics and variances that describes
a system or procedure.
Provided that flow rates are not too high, the reference method against which other sampling
procedures are compared is one where the entire stream is diverted into a vessel for a specified time or
volume interval. This method corresponds to the stopped-belt method described in ISO 12743.
