Products Description
IEC60601-1 Flammable Mixer Test Device Medical electrical equipment
Product Information:
1. Standard: conform to IEC60601-1:2012 Annex G.7.
2. Samples and restrictions: ME equipment, ME equipment parts and components heating flammable and anesthetic gas mixed with oxygen or nitrous oxide.
3. Application: For use in ME equipment areas heated with flammable and anesthetic gases mixed with oxygen or nitrous oxide, when disinfecting or cleaning skin with flammable anesthetics or flammable agents if the anesthetic or flammable agent is mixed with air or with oxygen or nitrous oxide After the nitrogen is mixed, check whether the sparks generated by the heating circuit of the heated ME equipment will ignite the anesthetic gas and check whether there is a risk of explosion.
4. Test principle: A motor is used to drive the shaft connected to the tungsten wire disk to rotate at a speed of 80r/min. The tungsten wire and the cadmium disk generate sparks by opening and closing the circuit under test, igniting the flammable anesthetic gas filled into the cavity, and verifying that the tungsten wire and the cadmium disk are used in conjunction with oxygen. Safety of circuits under test for ME EQUIPMENT heated by flammable anesthetic gases mixed with nitrous oxide or nitrous oxide.
Technical Parameters:
The test device consists of an ignition chamber and a contact device. The ignition chamber has a volume of at least 250cm³ and contains the specified gas or gas mixture. The contact device generates sparks by opening and closing. The contact device consists of a disk with two slots and another disk with four 0.2mm diameter tungsten wires. ; The free length of the second disc sliding the tungsten wire on the first disc is 11mm. The shaft connected to the tungsten wire disk rotates at a speed of 80r/min. The shaft connected to the spoke disk and the shaft connected to the tungsten wire disk rotate in opposite directions. The speed ratio of the shaft connected to the tungsten wire and the other shaft is 50:12. .
