Colour Testing of Nitrocellulose Propellants by a Spectrophotometric Method.

Abstract

The colour test is a test for chemical stability that can be applied to many of the nitrocellulose propellants stabilized with ethyl centralite. A spectrophotometric method has been developed for carrying out this test and for the preparation and checking of the associated standard colour solutions. Good agreement has been obtained with the method relying on visual comparisons. However, as visual comparisons of colour intensity are operator dependent and are more difficult at high intensities the spectrophotometric method is considered to be superior. The satisfactory matching of results with those of Materials Research Laboratories for identical propellant samples has established consistency of colour number determinations following transfer of gun propellant surveillance work to Weapons Systems Research Laboratory.
