Standards Development

Scope

This Document specifies a method for the determination of total moisture content of solid recovered fuels (SRF) by drying a sample in an oven. This method is suitable for use for routine production control on site, e.g. if a high precision of the determination of moisture content is not required. It is applicable to all solid recovered materials including solid recovered fuels.

NOTE 1 The total moisture content of solid recovered materials including solid recovered fuels is not an absolute value and therefore standardised conditions for its determination are indispensable to enable comparative determinations.

NOTE 2 The term moisture content when used with SRF can be misleading since these materials often contain varying amounts of volatile compounds (extractives) which can evaporate if determining moisture content by oven drying.

Purpose

There is currently no international standard for determination of total moisture using a simplified method of solid recovered fuels, a widely produced and internationally traded material. The main purpose of the proposal is to provide direction for this determination to be utilised in locations where there is an emphasis on an expeditious production of results. If a reference method was to be used where buoyancy of the sample containers is taken into account there may be an unacceptable delay in reporting the results.
