1.1 Requirements and tests This Recommendation specifies the metrological and technical requirements, test methods and maximum permissible errors for the type approval of grain moisture meters used in commercial transactions of cereal grains and oilseeds. 1.2 Indications This Recommendation applies to digitally indicating automatic grain moisture meters that directly display moisture content. 1.3 Application This Recommendation applies to moisture measuring instruments that estimate moisture based on indirect physical means (e.g. electrical or optical sensing). Drying methods or any other direct moisture measurement technology are not specifically covered, but may qualify if they perform to the requirements of this Recommendation. 1.4 Type of measuring instrument This Recommendation applies to grain moisture meters that measure the moisture content of a fixed representative-size grain sample. It does not apply to devices used for in-motion measurement of grain or seed moisture content. 1.5 New technology This Recommendation specifies instrument performance specifications
