Values derived from values of R(TP) in tables A1a-g.

2

A fractional difference in R(TP) of 4×10−6 is equivalent to a temperature interval of about 1 mK at the triple point of water.

3

Range: fractional difference between largest and smallest value of R(TP) in a single run.

4

Max: magnitude of largest fractional difference between two successive values of R(TP) in a single run.

5

RMS: root-mean-square of fractional differences between successive values of R(TP) in a single run.
