Although emission and immunity tests for medical products are very similar to those applied to other product types, such as radio equipment, networking equipment and multimedia equipment, IEC 6 requires that basic safety and essential performance of the medical device be maintained as opposed to the EMC compliance for other type of products. 1,2 As with any new standard edition, there are changes that necessitate additional evaluations of the product beyond those required by the previous edition. International Electrotechnical Commission (IEC) brought out comprehensive standard IEC 60601-1-2,1993 (first edition) to address EMC problems in medical.The fourth edition IEC/EN 6 (4 th Edition) will become a mandatory standard covering safety for medical devices on December 31, 2018.

By means of mecha-nical measures, the costs of product development can be reduced to a minimum, and the necessary time for approval procedures can be substantially shortened.PDF Printer Version (126 KB) Document issued on: June 24, 2007. If the implemented components such as connectors fulfill 2 MOPP and 2 MOOP on their own, e.g. Basic safety and essential performance requirements must be met for all devices.nents would already be fully compliant with the IEC 60601-1.The form of the test plan is now specified in Annex G of the 4 th edition. These are only some of the items that must be included in the test plan. Having determined the functions and their associated parameters that need to be evaluated during immunity tests, the next step is to develop a test plan that addresses how each function will be evaluated, identify those functions that can be evaluated simultaneously, and provide the cycle time for each of these functions.

Two possible problems might result in an unacceptable safety risk during operation: a power setting may change or the device could power-on unintentionally. A typical RF ablation system.![]() If the product incorporates a wireless receiver, an exclusion band shall not be used for the receiver operating frequency. However, if the risk management process identifies a different modulation frequency, it should be used. The 2 Hz modulation frequency that was specified for certain equipment in the previous edition is not in the 4 th edition. A review of the existing test report should be performed to determine the rate that was used.The AC power port surge test levels have not changed from those in the previous edition. The previous version of the standard did not specify the rate, so it may be that 5 kHz was used. Items indicated with an asterisk indicate this is something changed, new, or expanded for the 4th edition.The EFT/B test is specified to be performed using a 100 kHz repetition frequency. Note: 25/30 cycles means the test is per- formed over 10 cycles if tested with 50 Hz AC power and 12 cycles if tested using 60 Hz AC power. Use the hot rod mini bike kit for monsterThe 2 Hz modulation frequency that was specified for certain equipment in the previous edition is not in the 4th edition. The modulation frequency is specified only at 1 kHz. However, a new test level at certain ISM and amateur band frequencies of 6 Vrms has been added. It may be that other economies require different voltages and/or frequencies than those listed in the standard, so these should be delineated in the test plan.The other area in which the 4th edition is different from the previous edition is in the requirements for marking and instructions for use contained in Clause 5 of the 4th edition. Some of the tests specified in the previous edition to be performed at multiple voltages and frequencies are only required to be tested at a single voltage and frequency. If tests were performed for the previous version at 0 percent, the results comply with the 4th edition.The transient conduction on DC power tests, which are new in the 4th edition, only apply to products intended to be installed in vehicles with 12 or 24 V electrical systems.It should also be noted that the 4th edition includes a table delineating the voltage and frequency of the AC supply mains to be used during each test. Voltage interruptions changed only in that the previous edition allowed the interruption to be performed with up to a 5 percent residual voltage. Only the dip to 70 percent of nominal voltage was not changed. However, the 4th edition states that the test applies only to products with magnetically sensitive components or circuitry.Voltage dips have changed from those in the previous edition, which were <5 percent for ½ cycle, 40 percent for 5 cycles, and 70 percent for 25 cycles. Radio FunctionsAddressing radio functions is not something that is new in the 4 th edition but it is often overlooked. A test laboratory can conduct a review of the product and documentation provided to an end user against these requirements. However, many of the statements required to be included in the instructions for use are similar. Some of the tests that were likely performed on the radio module alone would still be representative of the use in the end product. Note: There are many cases where the radio standard's limits for transmitter radiated spurious emissions are less restrictive than the IEC/EN 6 limits.The radio function must be addressed during the testing of the complete product. An exemption for the main transmit signal from the radiated emissions limits (provided that they meet the national requirements) is given, but all other emissions must meet the radiated emissions limits of IEC/EN 6. Iec 60601 1 2 Portable Devices ShouldTable 2 shows the number of steps in the frequency ranges for both conducted immunity (0.15–80 MHz) and radiated immunity (80–2,700 MHz) and compares the total test time for a nominal sweep rate three seconds per frequency versus a sweep rate requiring 60 seconds per frequency.The test times for conducted immunity in Table 1 are compounded by the number of interface cables, with the test typically applied to each interface cable in turn.For radiated immunity, the device is typically tested four times (each side of the device facing the transmitting antenna) sides, but portable devices should be tested on all six sides. Note that the dwell time must be specified in the test plan.Both radiated and conducted immunity tests use a frequency step size of 1 percent and a typical sweep rate of 1–3 s. For example, if a device processes data by taking multiple samples and averaging them and providing a result every 60 seconds, the dwell time at each frequency step would be 60 seconds. The standard requires that the dwell time at each frequency step be long enough for the product to be exercised and respond. Cycle Time ConsiderationsAnother tip that is not new in the 4th edition addresses cycle time for each of the functions to be evaluated, which can have a significant impact on the time needed to perform radiated and conducted immunity tests. Warhammer 40k chaos godsInfusion pumps have their own product-specific basic standard: IEC/EN 6. Essential Performance Case StudiesCase #1: Infusion Pump. It must be noted that test modes have to be fully representative of the real-world application, so it may not always be possible to implement test-time-reducing features and meet the requirements of the notified body or government agency responsible for reviewing the test data. Depending on the function/process being evaluated, the test may need to be applied over multiple cycles.It may be possible to implement test modes in advance of testing that use fewer samples (thereby reducing the cycle time of the device) or allow multiple functions to be monitored simultaneously. For transient immunity tests, the issue of cycle time can also affect test times since the application of the transient cannot be synchronized to the “most susceptible” operating cycle of the device. A portable device, therefore, would be tested a total of 12 times.
