Specification for xylenes
One grade of benzene and three grades each of xylene and toluene. Appendices give test methods for measurement of colour, determination of density at 20ʻC, total sulphur content (reduction, Wickbold and lamp methods), free sulphur, residue on evaporation (ordinary and air-jet methods), crystallizing...
