IEC 60601-2-35 Medical Heating Devices Using Blankets And Pads
Testing Equipment
Product overview:
This device is used for electric blankets, electric heating pads
and other similar flexible heating appliances for heating the bed
or the human body, it is used to test the flame resistance of the
electric blankets, electric heating pads and other similar flexible
heating appliances for heating beds or human bodies, and to verify
whether the charged body arc flash causes overheating or burning of
the test sample.
Applied standards:
IEC 60601-2-35:2009 Medical electrical equipment - Part 2-35:

30.101.1 and Figure 113 and Figure 113a
Technical Parameters:
1. The spark ignition test device consists of a control box
(including 10KV power), heating chamber (optional) and bracket.
2. The test bracket is shown in Figures 113 & 113a of IEC
60335-2-17, the structure is made of stainless steel, insulation
material and brass.

3. Control Chamber:
A. Output Power: Voltage 0 ~ 15KV, current 0 ~ 2mA; when the
short-circuit current is 1mA, the voltage drop is less than 100V
B. Power on test time: 0 to 9999s, can be preset
C. Record time from power on to the flame reaches the inner edge of
the template: 0 to 9999 s
4. Natural ventilation heating chamber (optional):
A. Heating temperature: 0-200 °C can be preset, fluctuation ±1 °C
B. heating time 0 to 99 hours 59 minutes 59 seconds, can be preset
C. Inner size L*W*H = 450X450X500mm
Principles:
In the natural ventilation heating box, adjust the temperature to
65°C±2°C for 3h, and place the sample on the electrode of the
support frame made according to the standard as shown in the figure
below (the distance between the fixed electrode and the adjustable
electrode is 6.0mm± 0.01mm, it can be adjusted by adjustable
electrode), apply a sinusoidal rated voltage of 10kV to both ends
of the electrode, and connect an adjustable non-inductive resistor
in series, so that the short circuit is 1mA, and the output voltage
will not decrease by 100V, the power-on time is 2min , Record the
time from the start of power-on to the spark reaching the inner
edge of the template, take the average according to the standard
requirements and judge whether it is qualified or not.
