ABSTRACT
Following the dispersion ascertainment for the results obtained on proficiency testing
program of an assembly of identical low current equipments, the International Electrotechnical Committee (IECEx) decided to identify the dispersion sources of the
tests results.In this paper is analyzed, using theoretical and numerical models, the variable humidity impact ampleness of the testing mixture over the resulted sensitivity of the spark test apparatus. Thus, the paper will indirectly appreciate the impact of humidity over the spark test apparatus sensitivity by determination of humidity influence over concentration and also over the caloric properties of the testing mixture affected by humidity.

Keywords:humidity, spark test apparatus sensitivity
