Safety testing of medical devices: IEC 62353 explained.
If the detachable power supply cord and the me equipment or me system are measured together, the resistance shall not exceed mQ, see Figure 1. When measuring small iec 62353 currents, attention shall be paid to the manufacturer’s Information about limitations of the iec 62353 equipment.
In many cases, more rigorous electrical safety testing is needed after the replacement of components or reconfiguration iecc medical devices. It also shall be ensured that they continuously adapt their knowledge to the uec state of the art. For equipment not built to IEC these requirements may be iec 62353 taking into account the safety standards for the design and information in the instructions for use of that equipment.
Information provided by the manufacturer iec 62353 be taken into account see also 7. In this article, Iec 62353 T. For dated references, only the edition cited applies. This was the basis for the introduction of IECthe newly published international standard for medical electrical equipment—recurrent test and test after repair of ME equipment.
An Introduction to IEC – 24×7 Magazine
For equipment not built to lEC these requirements may be used taking into account the safety standards iec 62353 the design and information in the instructions for use of that equipment. When this requirement was discussed, it was agreed that the equipment is safe if the value is below the limit even if there is a significant increase.
NOTE 1 Local iec 62353 can establish limits for protective earth currents of the installation.
Insulation between applied parts and ground—this test is used to verify that the applied parts are adequately insulated from ground Class I or the enclosure Class II. For safety reasons, the short circuit current shall be limited to 3,5 mA. Insulation iec 62353 mains parts and ground—this test is used to verify that the mains parts are adequately insulated jec ground Class I or the enclosure Class II. Figures 4 iec 62353 5 provide a schematic representation of the applied part leakage test on Class I grounded ME equipment.
The motivation for most test requirements is the need to comply with statutory ie iec 62353 meet public liability considerations.
Iec 62353 all cases, when choosing a suitable electrical iec 62353 analyzer, care should be taken to ensure that it can be used to test in accordance with IEC requirements and that it is capable of performing accurate and repeatable test routines. Equipment shall be measured In all Intended functional conditions e. Disclosure to Promote the Right To Information Whereas the Parliament of India has set out to provide a iec 62353 regime of right to information for citizens to secure access to information under the control of public authorities, in order to promote transparency and accountability in the working of every public authority, and whereas the attached publication of the Bureau of Indian Standards is of particular interest to the public, particularly disadvantaged communities and those engaged in the pursuit of education and knowledge, the attached public iec 62353 standard is made available to promote the timely dissemination of this information in an accurate manner to the public.
NOTE 2 For me systems, the responsible party, who has assembled the system, will define the necessary measurement settings and methods as required in lEC This measuring method allows measurements on equipment that is not positioned insulated.

Requirements for special installations or locations — Medical locations Graphical symbols for use iec 62353 equipment Safety requirements for electrical equipment for measurement, control and laboratory use — Part 1: The term “all detachable power supply cords” covers the possibility of having a class ii equipment with a detachable supply cord including an earth conductor.

General requirements Ief ECSafety requirements for electrical equipment for measurement, control and irc use – Part Recently, iec 62353 test technology has been pioneered in the form of a new low-energy, high-current test that overcomes the previous contact-resistance problems that inhibited the wider application of protective iec 62353 testing using 1A or mA test iecc.
iec 62353 IVIeasurements according to lEC all editions may be performed. The reason for accepting these higher limits Is 26353 during the lifetime of the equipment under test, higher values may appear, e.

General requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. Accessories of the me equipment, which can affect the safety iec 62353 the equipment under test or the results of the measurements, shall be included in the tests. For an example to test documentation, see Figure G.
Other protective measures according to lEC shall take over the protection against electric shock during test. The acceptance criteria for insulation resistance values used in several countries are mainly based upon experience from that time. The highest value and the related condition, If relevant, iec 62353 be documented.
