You Get Speed and Accuracy With ARL Production Control Quantometers
determining copper and manganese in crude rubber ( D 297). A revision of the procedure for analysis of ash was also recommended. T h e Subcommittee on Crude Natural Rubber voted to set up a task group to study methods for determin ing the vulcanization behavior of rubber by the Mooney viscometer. Committee D-19 on Industrial Water. Revisions of t h e tests for carbon dioxide (D 513) and suspended and dissolved solids (D 1069) will be submitted in June. Stud ies of optical methods for turbidity in water have begun. T h e committee has nearly completed simplified methods for hardness, hydroxide, nitrite, and sulfite, to be recommended t o the American Society of Mechanical Engineers for inclu sion in the A S M E Boiler Test Code.
If you maintain quality control of materials by chemical analysis,
