Annotation of standard text ASTM E191-64(2017) :

This specification covers the design requirements of each component and basic equipment comprising the apparatus used for the microdetermination of carbon and hydrogen in organic and organometallic compounds along the lines of the conventional method of Pregl, but with modifications more in line with modern practice. Due to the diversity of this apparatus by which correct results can be obtained, this specification is intended to indicate what is acceptable rather than what is mandatory. The components covered here are the oxygen supply, pressure, regulator, drying and purifying tube, flowmeter, combustion unit, absorption tubes, guard tube, Mariotte bottle, and weighing accessories.
