Evacuation
Creation of a vacuum in a vessel
Feed water
Feed water is required to produce steam for sterilization.
Guide values for water quality in accordance with EN 285 /
EN 13060 – Appendix C
Fractionated vacuum procedure
A technical procedure in steam sterilization; the repeated
evacuation of the sterilization chamber in alternation with
steam injection.
Heat-up phase
The time required after the steam sterilizer has been
switched on / after the start of a sterilization program, to
heat the double-jacket steam generator before the steriliza-
tion procedure starts. The duration is dependent on tem-
perature at which sterilization takes place.
Hollow body A
See product with narrow lumen
Hollow body B
See simple hollow body
Load
The load refers to all possible instruments such as basins,
glassware and other objects which can be reprocessed in
a washer-disinfector.
Load
Products, devices or materials that are reprocessed to-
gether in one operating cycle.
Mixed loads
wrapped and unwrapped load within a single batch
Multiple wrapping
e.g. wrapped instruments sealed in a double layer of film or
wrapped in film and placed in an additional container or a
container wrapped in textiles.
Porous
Pervious to liquids and air, e.g. textiles
Porous full load
Serves to prove that the values set on the control satisfy
the necessary sterilization conditions in porous loads with
a maximum mass for which the sterilizer is designed in ac-
cordance with EN 13060 [see also EN 13060].
Porous partial load
Serves to prove that the values set on the control allow
steam to enter the pre-determined test package quickly
and equally [see also EN 13060]
Process evaluation system
Also known as the self-monitoring system – this observes
itself and compares the various sensors during a current
program.
Product with narrow lumen
An article open on one side to which the following applies:
1 ≤ L/D ≤ 750 and L ≤ 1500 mm or an article with an open-
ing on both sides which is: 2 ≤ L/D ≤ 1500 and L ≤ 3000
mm and which does not correspond to a hollow body arti-
cle B; L...length of hollow body article; D...Diameter of hol-
low body article [see also EN 13060]
Qualified electrician
Person with suitable technical training, knowledge and ex-
perience so that he or she can recognise and avoid haz-
ards that can be caused by electricity [see IEC 60050 or
for Germany VDE 0105-100].
RKI
Abbreviation for "Robert Koch Institute". It is one of the
most important bodies for the safeguarding of public health
in Germany.
Simple hollow bodies
An article open on one side to which the following applies:
1 ≤ L/D ≤ 5 and D ≥ 5 mm or an article with an opening on
both sides which is: 2 ≤ L/D ≤ 10 and D ≥ 5 L...hollow body
article length D... hollow body article diameter [see EN
13060]
Single wrapping
Wrapped once e.g. instruments sealed in foil – in opposi-
tion to: Multiple wrapping
Soft sterilization packaging
e.g. a paper bag or transparent sterilization packaging
Solid
Without hollows or gaps, solid, compact, closed
Solid load
Serves to prove that the necessary sterilization conditions
have been reached within the entire load with the values
set in the control. The load must represent the largest
weight of massive instruments designed for sterilization in
a sterilizer in accordance with EN 13060.
[see also EN 13060]
Sterile barrier system
A closed minimum packaging which prevents the entrance
of micro-organisms e.g. through sealing bags, sealed and
re-usable containers and folded sterilization towels etc.
Sterile material
Also referred to as a batch: a load which has already been
sterilized, i.e. is sterile
Sterilization chamber
The interior of a sterilizer accommodates the load
Sterilization material
Unsterile, sterilizable material which is still to be sterilized.
Vacuum
In common parlance, an area devoid of all material I n the
technical sense: volumes with a reduced gas pressure (at
least air pressure)
