19、 aspects of this electrical equipment and their electromagnetic environment. 2 Normative references The following referenced documents are indispensable for the application of this document.

22、ntended for use in the diagnosis of disease or other conditions, including a determination of the state of health, in order to cure, mitigate, treat, or prevent disease. Such instruments or apparatus are intended for use in the collection, preparation, and examination of specimens taken from the hum

23、an body. 4 General IEC 61326-1 applies, except as follows: BS EN 61326-2-6:2006Addition: 4.101 Electromagnetic environment of IVD medical equipment Similar to conventional medical electrical equipment, in-vitro diagnostic medical equipment is used in a wide variety of electromagnetic environments. I

24、VD devices shall function properly and safely in home environments, as well as in typical healthcare environments (hospitals, clinics, doctors offices). This means that the device shall have a minimum level of immunity appropriate for these areas. Devices intended for use in other environments, such

25、 as in ambulances, aircraft, cars or helicopters, may require a higher level of immunity to ensure the safe and effective performance of the device. 5 EMC test plan 5.1 General IEC 61326-1 applies. 5.2 Configuration of EUT during testing 5.2.1 General IEC 61326-1 applies. 5.2.2 Composition of EUT IE

27、n: 5.3.101 Operational conditions The device shall be set to conditions specified by the manufacturer. BS EN 61326-2-6:2006When different input power modes are available (e.g. battery, a.c. options), the manufacturer shall specify these mode(s) of operation, which cover(s) the most severe condition

28、in accordance with the product risk analysis. 5.4 Specification of performance criteria IEC 61326-1 applies. 5.5 Test description IEC 61326-1 applies. 6 Immunity requirements 6.1 Conditions during the tests IEC 61326-1 applies, except as follows: The configuration and modes of operation during the t

29、ests shall be precisely noted in the test report. Tests shall be applied to the relevant ports in accordance with Table 1. The tests shall be conducted in accordance with the basic IEC 61000 series of standards. The tests shall be carried out one at a time. If additional methods are required, the me

30、thod and rationale shall be documented. 6.2 Immunity test requirements Subclause 6.2 of IEC 61326-1 is replaced by the following: 6.2.101 Risk assessment and consideration of EMC immunity requirements Powerful electromagnetic emission sources can lead to malfunctions in nearby medical equipment unde

31、r certain circumstances. Different types of medical electrical equipment have different levels of risk with a malfunction. IVD medical equipment however is not intended to keep alive or resuscitate patients, so a malfunction would not directly cause the death or serious injury of a patient. Such a m

32、alfunction in IVD medical electrical equipment may result in an incorrect reading, which can in turn lead to a wrong therapeutic decision (misdiagnosis). For some analytes and in some circumstances, an incorrect result could result in serious harm to the patient. In the case of larger IVD electrical

33、 equipment, electromagnetic disturbances may also cause malfunctions that pose a direct threat to the operator, for example through unexpected mechanical movements. Refer to ISO 14971 for guidance in assessing risk associated with direct hazards and ISO 14971, Annex H for guidelines for assessing th

34、e risk to patients from incorrect IVD test results. NOTE As a rule, results from IVD medical equipment are checked for plausibility by medical personnel or followed-up by decisions of a healthcare professional. IVD medical equipment for self-testing by lay users are always provided with advice on ac

35、tion to be taken in case of indeterminate results. The users are urged to contact their medical practitioner first before making any decision of medical relevance. Risks associated with the use of IVD medical equipment are similar to risks associated with non-life-supporting medical equipment. There

36、fore the immunity test requirements given in following Table 1 are similar to the requirements for non-life-supporting medical equipment.

Applicable immunity phenomena from Table 1 shall be applied for each EUT operating mode. The EUT may show performance crite

Refer to ISO 14971 for guidelines for evaluation of residual risk acceptability. The performance criteria shall be included
