  2. Electrical safety testing - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_testing

    A concept introduced in the standard for medical electrical equipment IEC 60601-1. [4 ... The maximum allowable patient leakage current is 500μA AC and 50μA DC in ...

  3. IEC 60601 - Wikipedia

    en.wikipedia.org/wiki/IEC_60601

    The general standard IEC 60601-1 – Medical electrical equipment – Part 1: General requirements for basic safety and essential performance – gives general requirements of the series of standards. 60601 is a widely accepted benchmark for medical electrical equipment and compliance with IEC60601-1 has become a requirement for the commercialisation of electrical medical equipment in many ...

  4. Power entry module - Wikipedia

    en.wikipedia.org/wiki/Power_entry_module

    Medical devices can and do take advantage of power entry modules. Power entry modules are available with electromagnetic interference filters with very low leakage current ratings, even those suitable for direct patient contact in accordance with UL 544 and IEC 60601-1. Shock-safe fuseholders have also been integrated into power entry modules.

  5. Comparative Tracking Index - Wikipedia

    en.wikipedia.org/wiki/Comparative_Tracking_Index

    Testing method is specified in IEC standard 60112 and ASTM D3638. To measure the tracking, 50 drops of 0.1% ammonium chloride solution are dropped on the material, and the voltage measured for a 3 mm thickness is considered representative of the material performance. Also term PTI (Proof Tracking Index) is used: it means voltage at which during ...

  6. Network isolator - Wikipedia

    en.wikipedia.org/wiki/Network_isolator

    Network isolators are used in medical devices to protect patients against leakage currents. Network connections between medical devices and Ethernet networks (and other non-medical devices, such as personal computers) must be in accordance with the IEC 60601-1 standard. This standard specifically deals with medical electronic and electrical ...

  7. Bioinstrumentation - Wikipedia

    en.wikipedia.org/wiki/Bioinstrumentation

    Type designations are defined by the IEC 60601 standard. Type B applied parts have a maximum leakage current of 100μA and cannot be directly connected to the heart. Type BF applied parts have the same requirement for maximum leakage current, but differ in the fact that they are an isolated or floating device with conductive contact with the ...

  8. Dielectric withstand test - Wikipedia

    en.wikipedia.org/wiki/Dielectric_withstand_test

    The current can trip a fault indicator. The tester has output overload protection. The test voltage may be either direct current or alternating current at power frequency or other frequency, like resonant frequency (30 to 300 Hz determined by load) or VLF (0.01 Hz to 0.1 Hz), when convenient. The maximum voltage is given in the test standard ...

  9. EEG DIN connector - Wikipedia

    en.wikipedia.org/wiki/EEG_DIN_connector

    In 1989, the Deutsches Institut für Normung issued DIN 42802, [1] standardizing a "touch-proof connector for electromedical applications." It became widely adopted when regulatory bodies pressured the industry to insulate connectors in clinical settings, as specified in IEC 60601 -1 (subclause 56.3(c)).
