Feed water
Is required for the creation of water steam for the
sterilization; typical values for the water quality according
to
→DIN EN 285 or →DIN EN 13060 – Appendix C, at
least however battery water according to →VDE 0510
FTP
(engl.: File Transfer Protocol) is a data communication
method which serves for the transmission of data from the
internet. These data can contain programs, files or
information. Special FTP programs (FTP clients) serve for
uploading any data on a server.
Fractionated flow method
Overpressure method in which the air is expelled from the
chamber and the items to be sterilized by alternating
between steam entry and steam outlet.
Hollow bodies A
One-sided open bodies, for which applies:
1 = L/D = 750 and L = 1500 mm or
a double-sided open body for which applies:
2 = L/D = 1500 and L = 3000 mm and which does not
correspond to the hollow body B
L…hollow body length
D…hollow body diam
Hollow bodies B
One-sided open bodies, for which applies:
1 = L/D = 5 and L = 5 mm or
a double-sided open body for which applies:
2 = L/D = 10 and D = 5
L…hollow body length
D…hollow body diameter
[→DIN EN 13060]
Initialization
Creation of a certain initial state of the →software at start-
up
Integrated steam generation
The steam generator is located directly on the floor of the
sterilization chamber
Items to be sterilized
Unsterile objects, materials still to be sterilized
LED
Abbreviation for Light Emitting Diode; Semiconductor
diode which lights up when powered by current. LEDs are
predominantly employed for status displays in devices, for
example to display hard disk access.
Lubricants
Instrument oil or instrument milk
Mixed load
Wrapped and unwrapped materials to be sterilized within
one load
Multiple wrapping
e.g.
instruments doubly sealed in foil or wrapped in foil are
additionally found in one container or in a textile wrapped
container
Porous
Pervious to liquids and air, e.g. textiles
Porous full load
– Check of porous full load
Serves to verify that for the values set on the control, the
required sterilization conditions are achieved in porous
loads with the maximum mass for their sterilization in a
sterilizer designed according to
→DIN EN 13060
[DIN EN 13060]
Porous partial load
– Check of porous
partial load
Serves to verify that for the values set on the control, the
steam quickly and uniformly penetrates into the defined
test packet
[→DIN EN 13060]
Porous small parts
Made of materials which can absorb fluids (e.g. liquids)
Pre-vacuum method
iIn contrast to the fractionated vacuum method, a vacuum
is created only once to remove the air from the sterilization
chamber; not so suitable for complicated hollow bodies
such as Type A
Process evaluation system
Also self-monitoring system
– observes itself, acts during
the programs, compares sensors with each other
Pulsating overpressure drying
Drying method which removes moisture from the chamber
and the items to be sterilized by alternating between air
entry and discharge
RKI
Robert Koch Institute
Self-Monitoring-system
Process evaluation system
Separate steam production
The steam generator is located outside the sterilization
chamber. The sterilization chamber is protected from
overheating in this way.
Simple wrapping
Wrapped once, e.g. instruments sealed in a foil.
–
contrasted to: →Multiple wrapping
Software
non-material components of a EDP system; e.g. computer
programs
Soft sterilization package
e.g. paper bags or clear-plastic sterilization packages
Solid
Without hollows or spaces; firm, dense, closed
Solid load
– check of solid load
Serves to verify that for the values set on the control, the
required sterilization conditions were achieved within the
entire load. The load must represent the maximum
measurements of solid instruments for whose sterilization
a sterilizer has been designed according to →DIN EN
13060 [DIN EN 13060]
Standards-compliant
Conformity with all the relevant standards
Sterile barrier systems
Closed minimum packaging which prevent the occurrence
of microorganisms, e.g. bags closed with sealing, closed
reusable containers, folded sterilization cloths
Sterilized items
Also designated as
→batch, if already successfully
sterilized: sterile goods
