Received Condition: Good

Type: Production 

Description of Equipment Under Test (provided by client)

The Portable Oxygen Concentrator is intended to provide supplemental oxygen in a home, institutional, or 

travel environment. The Portable Oxygen Concentrator is intended to deliver concentrated oxygen for adult 

patients with chronic pulmonary diseases such as chronic bronchitis, emphysema, asthma, or lung cancer, 

those in the terminal stage of cancer, or any patient requiring supplemental oxygen. The device is portable, 

enabling patients who need an oxygen device to be treated at home according to a clinician’s prescription or 

direction. The Portable Oxygen Concentrator is a prescription-only device, is not intended for use in lifesupporting or life-sustaining situations, and is provided non-sterile. It is designed to be used indoors or 

outdoors. 

The Portable Oxygen Concentrator is not intended to be used: 

• In life-supporting or life-sustaining situations. 

• In an operating or surgical environment. 

• With a non-adult population. 

• In conjunction with flammable anesthetic or flammable materials

6 Radiated Emissions 

6.1 Method 

Tests are performed in accordance with CISPR 11, and RTCA DO-160, Rev G, Section 21, Category M. 

TEST SITE: Three-Meter Chamber (IEC 60601-1-2)

The Three-Meter Chamber is a semi-anechoic chamber utilized for measuring emissions at a distance of 

three meters. The dimensions of the Three-Meter chamber are: 18.0 ft. in length, 25.8 ft. in width, 16.0 ft. 

in height. A turntable built into the floor of the chamber is used to rotate test samples per methods 

described in CISPR 16 for radiated emissions. An antenna mast is used with a Bi-Log antenna to measure

emissions from the samples under test at different height requirements described in CISPR 16. 

TEST SITE: Small-Mil and Large-Mil Chamber (RTCA DO-160G) 

The Small-Mil and Large-Mil Chamber are semi-anechoic chambers utilized for performing EMC testing. 

The dimensions of the Small-Mil Chamber are: 12.13 ft. in length, 16.25 ft. in width, and 10.08 ft. in height. 

The dimensions of the Large-Mil Chamber are: 15.9 ft. in length, 20.0 ft. in width, and 9.6 ft. in height. 

Each Chamber holds a test bench with a ground plane made of copper. The ground plane is connected to 

the chamber ground using copper straps that meet criteria required by RTCA DO-160.

Radiated Emissions, 3m 30-1000 MHz 5.12 6.3 

Sample Calculation 

The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the 

measured reading. The basic equation with a sample calculation is as follows: 

FS = RA + AF + CF - AG 

Where FS = Field Strength in dBμV/m 

RA = Receiver Amplitude (including preamplifier) in dBμV 

CF = Cable Attenuation Factor in dB 

AF = Antenna Factor in dB 

AG = Amplifier Gain in dB 

In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the 

following table is as follows. 

Assume a receiver reading of 52.0 dBμV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The 

amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBμV/m. This value in dBμV/m was converted to its corresponding 

level in μV/m. 

 

RA = 52.0 dBμV 

AF = 7.4 dB/m 

CF = 1.6 dB 

AG = 29.0 dB 

FS = 32 dBμV/m 

To convert from dBμV to μV or mV the following was used: 

UF = 10(NF / 20) where UF = Net Reading in μV 

 NF = Net Reading in dBμV 

Example: 

FS = RA + AF + CF – AG = 52.0 + 7.4 + 1.6 – 29.0 = 32.0 

UF = 10(32 dBμV / 20) = 39.8 μV/m

7 AC Mains Conducted Emissions 

7.1 Method 

Tests are performed in accordance with CISPR 11. 

TEST SITE: Reverberation Chamber

The Reverberation Chamber is a shielded chamber designed specifically for reverberation testing. The 

dimensions of the Reverberation Chamber are: 18.2 ft. in length, 28 ft. in width, 10.1 ft. in height. A copper test 

bench with dimensions of 8.0 ft. in length, 5 ft. in width, and 2.3 ft. in height is used for testing. The copper test 

bench is grounded to the chamber with copper straps attached to the ground plane of the reverberation 

chamber per requirements of RTCA DO-160, Rev G. The Reverberation Chamber was used specifically as a 

shielded test area for testing. 

Measurement Uncertainty (IEC 60601-1-2) 

Measurement Frequency Range Expanded Uncertainty (k=2) Ucispr 

AC Line Conducted Emissions 150 kHz - 30 MHz 1.1 3.4 

Sample Calculations

The following is how net line-conducted readings were determined: 

NF = RF + LF + CF + AF 

Where NF = Net Reading in dBμV 

 RF = Reading from receiver in dBμV 

 LF = LISN or ISN Correction Factor in dB 

 CF = Cable Correction Factor in dB 

 AF = Attenuator Loss Factor in dB 

 

To convert from dBμV to μV or mV the following was used: 

UF = 10(NF / 20) where UF = Net Reading in μV 

 NF = Net Reading in dBμV 

Example: 

NF = RF + LF + CF + AF = 28.5 + 0.2 + 0.4 + 20.0 = 49.1 dBμV 

UF = 10(49.1 dBμV / 20) = 285.1 μV/m

Deviations, Additions, or Exclusions: 

 For the RTCA DO-160, Rev. G portion, the Oxygen Concentrator was tested on a non-conductive foam 

support instead of on the ground plane during testing as required per standard. This was acceptable for 

testing as it created a harsher test environment for the Oxygen Concentrator.

12 Electrical Fast Transient/Burst Immunity Test 

12.1 Method 

Tests are performed in accordance with IEC 61000-4-4. 

TEST SITE: Reverberation Chamber

The Reverberation Chamber is a shielded chamber designed specifically for reverberation testing. The 

dimensions of the Reverberation Chamber are: 18.2 ft. in length, 28 ft. in width, 10.1 ft. in height. A copper test 

bench with dimensions of 8.0 ft. in length, 5 ft. in width, and 2.3 ft. in height. The copper test bench is grounded 

to the chamber with copper straps attached to the ground plane of the reverberation chamber. In this case the 

chamber is just being used as a shielded room not in the reverberation mode.

17.1 Method 

Tests are performed in accordance with RTCA DO-160, Rev G. 

TEST SITE: Reverberation Chamber

The Reverberation Chamber is a shielded chamber designed specifically for reverberation testing. 

The dimensions of the Reverberation Chamber are: 18.2 ft. in length, 28 ft. in width, 10.1 ft. in height. 

A copper test bench with dimensions of 8.0 ft. in length, 5 ft. in width, and 2.3 ft. in height. The copper 

test bench is grounded to the chamber with copper straps attached to the ground plane of the 

reverberation chamber. In this case the chamber is just being used as a shielded room not in the 

reverberation mode.

5.2.1 Instructions for Use 

The following statements need to be included in the users manual for all equipment and systems: 

1) “Medical Electrical Equipment needs special precautions regarding EMC and needs to be 

installed and put into service according to the EMC information provided in the 

Accompanying Documents.” 

2) “Portable and Mobile RF Communications Equipment can affect Medical Electrical 

Equipment.” 

5.2.2.1 Technical Description 

The following information must be included in the Accompanying Documents provided to the end 

user for all equipment and systems: 

a) A list of all cables and maximum lengths of cables (if applicable), transducers and other 

accessories with which the manufacturer claims compliance with the requirements of 

IEC60601-1-2 ed3.0 (2007-03) Sections 6.1 and 6.2. 

b) A warning: “The use of accessories, transducers and/or cables other than those specified, 

with the exception of those sold by the manufacturer as replacement parts for internal 

components, may result in increased emissions or decreased immunity of the equipment 

or system.” 

c) Guidance Table 1 must be provided to the end user.

d) A warning: “The equipment or system should not be used adjacent to or stacked with 

other equipment and that if adjacent or stacked use is necessary, the equipment or 

system should be observed to verify normal operation in the configuration in which it will 

be used.” 

e) A justification must be provided for each reduced compliance level that is lower than the 

published levels for immunity tests in IEC 60601. The justifications must be based on 

physical, technological or physiological limitations that prevent compliance with the 

published test levels. 

f) Guidance Table 2 must be provided to the end user.

5.2.2.2 Technical Description 

The following information must be included in the Accompanying Documents provided to the end 

user for all equipment and systems:
