Метрологическое обеспечение измерения коэффициента теплопроводности

A two-stage method of intralaboratory research of characteristics of accuracy of the method of measurement of thermal conductivity was developed and implemented. The criterion determining the necessity of performing the second stage of research was formulated. The technique allows to identify sources influenced on the result of measurement of thermal conductivity, and also to control characteristics of the method (precision). Recommendations for research of the National reference unit of thermal conductivity were developed.
