3.1

Electrical safety to DIN EN 62353 (IEC 62353)

NOTE

The Oxylog under test meets the conditions of protection class 2.

Oxylog 3000 plus only: With the MCable-Mainstream CO2 sensor (sensor

connected) the Oxylog 3000 plus corresponds to type BF.

NOTE

The tester, e.g. SECUTEST, must be correctly configured for all measurements (perform protective conductor test with setting „Protection class I“). If

implausible measurement results are obtained, such as a leakage current of

0.0 µA, check the tester configuration in addition to the test setup!

NOTE

– In testing to IEC 62353, the medical electrical device (ME device) or the

medical electrical system (ME system) must be tested.

– ME systems must be treated like ME devices.

– An ME system is a combination of several devices, as specified by the

manufacturer, of which at least one must be an ME device, which are

interconnected by a functional connection or by means of a multiple

socket outlet.

NOTE

With devices that are connected to other devices by means of a data cable,

this connection must be disconnected prior to performing the electrical safety check, in order to avoid incorrect measurements.

3.1.1

Device leakage current

NOTE

– The device leakage current can be tested by the direct measurement

method or the differential measurement method.

– For direct measurement, set up the device under test so that it is insulated and scan all touchable conductive components using the probe.

– Differential current measurements often produce different measured values from direct measurements.

NOTE

The measurement must be performed twice! The second test is performed

with the plug rotated 180° in the socket. In many test devices the mains plug

rotation is simulated by means of a built-in selector switch. The higher measured value must be documented.

NOTE

The reference value (initial measured value) must always be transmitted!

NOTE

If the measured values are between 90% and 100% of the permissible limit

value, the reference value and the previously measured values of the recurrent test should be applied to assess electrical safety!

Test

Result

The reference value must not exceed 100 µA.

Electrical safety according to IEC 60601

NOTE

The Oxylog under test meets the conditions of protection class 2.

Oxylog 3000 plus only: With the MCable-Mainstream CO2 sensor (sensor

connected) the Oxylog 3000 plus corresponds to type BF.

NOTE

The following presents a description of the electrical safety tests according

to IEC 60601. Whether the standard is applicable or not depends on national regulations and its use must be decided on site under consideration of applicable national regulations.

NOTE

The tester, e.g. SECUTEST, must be correctly configured for all measurements (perform protective conductor test with setting „Protection class I“). If

implausible measurement results are obtained, such as a leakage current of

0.0 µA, check the tester configuration in addition to the test setup!

NOTE

– When testing according to IEC 60601, systems must be tested and not

individual devices.

– Systems should be treated as devices.

– A system is a combination of several devices of which at least one is a

medical electrical device which is connected to other devices by functional connections or by a transportable multiple socket outlet.

NOTE

With devices that are connected to other devices by means of a data cable,

this connection must be disconnected prior to performing the electrical safety check, in order to avoid incorrect measurements.

NOTE

The test to UL2601-1 is satisfied by testing to IEC 60601. Differing limit values are marked.

• Prepare the test setup.

• Set the flow adjuster on the Alduk III to 15 L/min.

• Make the following settings on the Oxylog:

– Ventilation mode = VC-CMV/IPPV

– Frequency = 10 1/min

– Alarm limit Pmax = 60 mbar (US variant Oxylog 3000, 2000 plus =

100 mbar)

– FiO2 = O2 100%

– Tplat = 50%

– Trigger = off

– VT = 2000 mL

• Set the I/E so that a flow of 55 L/min (54 to 56) is produced.

Test

The pressure on the high-pressure measuring device of the Alduk III is

greater than 50 bar.

The pressure on the digital manometer is 4.3 bar to 4.7 bar.

Action

• Switch off the Oxylog.

Test

The pressure does not rise above 6 mbar.

Action

• Close the flow adjuster on the Alduk III.

• In place of the digital manometer, connect an appropriate flow tube from

the flowmeter block (7901161).

• Set the following flow values and check (these apply to an ambient pressure of 1013 mbar):

• Close O2 cylinder.

• Wait until there is no more back pressure.

Test

Action

The high-pressure measuring device of the Alduk III indicates no pressure.

• Remove the AGSS/Alduk III connection on the Alduk III.

• In place of the flow tube, connect a high-pressure pump and build up a

pressure.

Test

The opening pressure of the safety valve is greater than 6.3 bar (10 bar must

not be exceeded).

Action

• Mark the Alduk III, with the service label, for example, to indicate when the

next check is due.

Input

Condition and function checked. Enter date of next test.
