Physical Chemical Properties Of Methane

This document is one in a series prepared by the Committee that form the basis of the recommendations for EELs and CELs for selected chemicals. Since the Committee began recommending EELs and CELs for its military sponsors (U.S. Army, Navy, and Air Force), the scope of its recommendations has been expanded in response to a request by the National Aeronautics and Space Administration. The CELs, in particular, grew out of a Navy request for exposure limits for atmospheric contaminants in submarines. The EELs and CELs have been used as design criteria by the sponsors in considering the suitability of materials for particular missions (as in a submarine or a spacecraft) and in assessing the habitability of particular enclosed environments. They are recommended for narrowly defined occupational groups and are not intended for application in general industrial settings or as exposure limits for the general public.

Briefly states the method used by the Bureau of Mines in determining the heating value and other properties of fuel products derived from the petroleum mentioned and gives the results of the examination of a large number of samples. Also describes an electric still for fractionating petroleum and briefly summarizes the methods used in analyzing natural gas.
