    skos:prefLabel "Ash free"@en ;
    skos:scopeNote "A solid fuel analysis basis, calculated from a measured ash content rather than weighed."@en .

    skos:prefLabel "Contained substance"@en ;
    skos:scopeNote "The substance counted is the one the material declares as its own type; no separate property names it."@en .

    skos:notation "mineral-matter-free" ;
    skos:prefLabel "Mineral matter free"@en ;
    skos:scopeNote "A solid fuel analysis basis. Mineral matter exceeds ash, so this figure is smaller than the ash free figure for the same sample."@en .

    skos:prefLabel "Payable substance"@en ;
    skos:scopeNote "A commercial basis, not a physical one. Deductions vary by contract, so two payable figures are not comparable even for the same material, and a payable figure must not be used for conservation accounting or for reconciliation against production statistics."@en .

    skos:notation "recoverable" ;
    skos:prefLabel "Recoverable substance"@en ;
    skos:scopeNote "An engineering estimate of what a named process would extract, not a measurement of what is present. Always smaller than the contained figure, and routinely confused with it."@en .
