Abstract:
Various methods used for testing thermocouples and thermocouple materials and the precautions that must be observed in order to attain various degrees of accuracy are described. In particular, the methods that have been developed and used at the National Bureau of Standards are outlined in detail, and some guidance is given to the reader in the selection of the method best adapted to a given set of conditions.

Abstract:
A gas analyzer for evaluating aircraft fire-extinguishing systems was calibrated for use with carbon dioxide, methyl bromide and bromochloromethane. Extensive application of the analyzer in evaluating the carbon dioxide system of the XB-45 power plant provided it to be of practical value. Operation of the instrumentation flight proved satisfactory.

Abstract:
The preceding papers have presented an apparatus and procedures for the study of heat transfer on contact with flame (1), and the validation of a mathematical system of analysis of the data so obtained (2). The present report describes the procedure for the determination of diffusivity and thermal conductivity and its application to fabrics made of the heat resistant synthetic (DuPont HT-1) discussed in the first of this series of papers.
