Air leakage
is a location through which air can pass in and out without
this being desired. Verification of the leakage serves to
prove that the volume of air ingress in the chamber during
the vacuum phase does not exceed a value which would
prevent steam penetration of the sterilizer load and that the
air leakage does not cause the possible contamination of
the sterilizer load during the drying phase.
Authorised technician
The term "authorised technician" refers to an employee of
a customer service provider or stockist who has been
trained and authorised by MELAG to perform maintenance
and installation work on MELAG devices. Only they may
carry out this work.
Batch
The batch is the composition of items which has been sub-
ject to the same reprocessing procedure.
Bowie & Dick test
Steam penetration test with a standard test package; de-
scribed in EN 285; the test is recognized in the large-scale
sterilization industry.
Competent personnel
Trained personnel in accordance with national specifica-
tions for the respective area of application (dentistry, medi-
cine, podiatry, veterinary medicine, cosmetics, piercing,
tattoo) with the following contents: knowledge of instru-
ments, hygiene and microbiology, risk assessment and
classification of medical devices and instrument reprocess-
ing.
Condensate
Fluid (e.g. water) produced by the cooling of and resultant
separation from the vaporous state.
Conductivity
is the ability of a conductive chemical substance or mixture
of substances to conduct or transfer energy or other sub-
stances or particles in space.
Corrosion
The chemical alteration or destruction of metal materials by
water and chemicals
Delay in boiling
This refers to the phenomenon that it is possible under cer-
tain circumstances to heat a fluid beyond its boiling point
without them boiling. This represents an unstable state;
even low-level agitation can produce a large bubble within
the shortest period, which expands explosively.
Demineralised water
Water without the minerals usually found in normal spring
or tap water; is produced through ion exchange of normal
tap water. It is used here as feed water.

Distilled water
From the Latin aqua destillata; also referred to as aqua
dest; water which to a great extent is free from salts, or-
ganic material and micro-organisms, is produced from nor-
mal tap water or pre-cleaned water through the process of
distillation (evaporation and subsequent condensation).
Distilled water is used, for example, as feed water for
steam sterilizers.
Dynamic pressure test of the sterilization chamber
Serves to prove that the rate of pressure variations during
a sterilization cycle does not exceed a particular value
which could result in the damage of the packaging materi-
al. [see also EN 13060]
Empty chamber test
Test run without a load, performed to assess the perfor-
mance of a sterilizer without the influence of a load; facili-
tating verification of the temperatures maintained in com-
parison to the temperatures set. [see EN 13060]
