Tests for assuring the integrity of a qualified cell and of cells yet to be qualified are given.
Precautions for handling the cell to avoid breakage are also described.
1.2 The effect of hydrostatic pressure on the temperature of a water triple-point cell is discussed.
1.3 Procedures for adjusting the observed SPRT resistance readings for the effects of self-heating and hydrostatic pressure
are described in Appendix X1 and Appendix X2
