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: Particular requirements for the basic safety and essential performance of heating devices using blankets, pads and mattresses and intended for heating in medical use

+AMD1:2016CSV, MOD

IEC60335-2-17:2012 "Household and similar electrical appliances-Safety-Part2-17:Particular requirements for blankets, pads and similar flexible heating appliances"

GB4706.8-2008 "Safety of household and similar electrical appliances - Particular requirements for electric blankets, electric heating pads and similar flexible heating appliances" 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.
