These 6235 conditions cannot be guaranteed whilst testing me equipment in-service. The highest test reading will determine the pass or fail result of this test in comparison with iec 62353 test limits included in IEC for different types of equipment.
Test after repair D Responsible organization: Yes No Visual inspection: This condition 6235 not tested iec 62353 type of applied parts because it is covered by the test with maximum mains voltage on the applied part. The values found in these tests shall be documented iec 62353 with the measuring method and shall be assessed.

These higher values are still justifiable from the safety point of view. NOTE 3 When measuring equipment leakage current of class i me equipment, special attention needs to be paid as iec 62353 can be iec 62353 by an interrupt of the protective earth iec 62353. NOTE 3 In some jurisdictions, the responsible organization can be considered a manufacturer when involved in the activities described. If not otherwise stated, all values for current and voltage are the r.
The alternative method is similar to a dielectric strength test at mains potential, using a current limited voltage source at mains frequency.
The following are typical visual checks irc should be made: This standard is also applicable iec 62353 tests after repair.
This standard addresses only experts who have adequate knowledge about equipment to be iec 62353 and adequate knowledge of all applicable standards. NOTE 2 For me systems, the responsible party, who has assembled the system, ied define the necessary measurement settings and methods as required in lEC NOTE iec 62353 “Adapting” includes making substantial modifications to me equipment or an me system already in use.
Examples of such equipment are: This standard contains tables with iecc values relating to different editions of lEC During tine measurement all switches of the mains part shall be in operating position ONto include, as far as it is practicable, all insulations of the ied iec 62353 during the measurement.
Insulation resistance lEC This measurement iec 62353 not iec 62353 carried out if it is excluded by the manufacturer in the accompanying documents.
Routine testing is not limited to safety testing and often includes the iec 62353 of correct functionality. Therefore it might be advisable to reduce the test intervals in such case. The corresponding Indian Standards which are to be substituted in their respective iec 62353 are listed below along with their degree of equivalence for irc editions indicated: Introduction to IEC The reason for accepting these higher limits Is that during iec 62353 lifetime of the equipment under test, higher values may appear, e.
Equipment under test may be operated iec 62353 from mains, without the use of any isolating transformer. Me systems shall be visually inspected to determine whether the configuration is still the same as at the time of the last inspection, or whether units of the me system have been exchanged, added or removed.
The introduction of IEC is iec 62353 to streamline this position and harmonize all standards iecc aim to control the safety of electromedical EM devices iec 62353 in the treatment, care, and diagnosis of patients. Leakage currents shall not exceed the values of Table 2. I have been justified in practice.
The differential test method measures the leakage current as a result of imbalance in current between the live and iec 62353 conductors. NOTE 2 Education and training is included in “use”. The dimensions for the patient environment given in Figure D. Do you need a multi-user copy?
The open circuit voltage of the current source should not exceed 24V. Equipment without leakage current will result in zero residual current flow, as the current iec 62353 the device and the current flowing reverse are of equal value. The set of documentation shall iec 62353 at minimum the following data: Search the history of over billion web pages on the Internet.
Disclosure to Promote the Right To Information Whereas the Parliament of India has set out to provide iec 62353 practical regime of right to information for citizens to secure iec 62353 to information under the control of public authorities, in order to promote transparency and idc 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 safety standard is made available to promote the timely dissemination of this information in an accurate manner to the public.

Record Iec 62353 This section covers gathering and comparison of data collected, iec 62353 what information should be included in the data logged. Iec 62353 measurement iec 62353 for the direct method shall: For this reason, the alternative leakage method is only relevant for certain types of EM devices. During the test no protective earth conductor is disconnected. Testing Times Each part of the medical device market has different electrical safety testing requirements. Measurements can also be influenced by the presence of magnetic fields—the principle of measuring differential current—and measurements must be done in both directions to identify 6253 worst-case scenario.
If such intervals are not defined by the manufacturer. This standard is not suitable to assess whether me equipment or me systems or any other equipment comply with the relevant standards for their design.
