Metrological Characteristics of K-1 and K-3 Reference Benzoic Acids

  • Published:
Measurement Techniques Aims and scope

Abstract

A principle is presented for reproducing the unit of combustion energy, the joule, on the GÉT 16-96 State Primary Standard, which is based on using high-purity benzoic acid grade K-1. Metrological characteristics are given for various types of benzoic acid produced in various countries and used in combustion calorimetry. A comparison is made of the combustion energies for Russian K-3 benzoic acid and American 39i, which have been obtained with a GÉT 16-96.
