–LAN, Battery
can be used in a transport environment such as a road ambulance, airplane or helicopter. For this
purpose the monitor fulfils the following additional mechanical, EMC and environmental
requirements:
• Shock Tests according to IEC TR 60721-4-7, Class 7M3. Test procedure according to IEC/EN
60068-2-27 (peak acceleration up to 100 g).
• Random Vibration according to IEC TR 60721-4-7, Class 7M3. Test procedure according to IEC/
EN 60068-2-64 (RMS acceleration 5 g).
• Sinusoidal Vibration according to IEC TR 60721-4-7, Class 7M3. Test procedure according to
IEC/EN 60068-2-6 (acceleration up to amplitude 2 g).
• Bump Test according to IEC/EN60068-2-29 (peak acceleration 15 g, 1000 bumps).
• Free Fall Test according to EN1789 (covers also IEC TR 60721-4-7 and Class 7M3). Test
procedure according to EN 60068-2-32 (height 0.75 m).
•Specification for degrees of protection provided by enclosures according to IEC/EN 60529: IP 32
• EN 1789 +A1:2003 Medical vehicles and their equipment - Road ambulances (chapter 6 - Medical
Devices).
• Radiated susceptibility 20 V/m according to EN ISO 9919 (SpO
2
) and EN ISO 21647 (CO
2
).
• Altitude Range from -500 to 3000 m operating and -500 to 4600 m storage and transportation.
• Extended radiated susceptibility tests
The X2 Multi-Measurement Module/patient monitor with its out-of-hospital parameter set provides a
general immunity level of 20 V/m with only few restrictions. Details are as listed below:
–GSM 900: Immunity at 900MHz (uplink mobile phone), 20 V/m (ECG:10V/m), duty cycle
1:8
–GSM 1800: Immunity at 1800MHz (uplink mobile phone), 20V/m, duty cycle 1:8.
–DECT: Immunity at 1800MHz (digital cordless phone), 20V/m, duty cycle 1:24
–AM: 1kHz Immunity from 80MHz to 1.0GHz (any radio communication unit, broadcasting
and TV transmitter), 20 V/m, modulation factor 80%.
(ECG: 20 V/m except 600-950 MHz
where it is 10 V/m and Temperature which holds 3 V/m over the full range).
CAUTION Temperature measurement accuracy may be compromised in the presence of strong electromagnetic
fields (>3 V/m) in certain small frequency bands.
• Magnetic Field emission according to MIL STD 461E, Chapter RE101: Radiated emissions,
magnetic field, 30 Hz to 100 kHz. Limit class: Army.
• Magnetic Field susceptibility: Radiated susceptibility, magnetic field, 50, 60 and 400 Hz,
18 µT(15 A/m)
• Operating ambient temperature testing over the range from 0 to 40°C (32 to 100°F).
• Operating ambient humidity testing up to 95% RH at 40°C (100°F), non condensing.
NOTE Additional requirements can be necessary for transport situations in air, on water or in difficult terrain
in certain countries, e.g. EU.
