Method for the Determination of Particulate Mass Flows in Enclosed Gas Streams
1.1 Scope
1.1.1 This Standard describes test procedures and equipment which will permit accurate and reproducible determination of the particulate mass flows in enclosed gas streams. It is intended for use both before and after gas cleaning equipment (performance testing) or prior to emission of the gas stream into t he atmosphere. Note. It is recommended that the testing procedures in…

Specification of a semi-quantitative method. The content of free ammonia in a moulded article is of importance, when corrosion of metal inserts or contamination in contact with the article has to be considered. Distillation of the aqueous extract from a powdered test portion, coloration of the distillate by reaction with Nessler reagent and comparison of the colour with that of standard matching…
