Pass Pass Pass Pass 4 OTHER COMMENTS 4.1 General: The RF field tests are performed in a 10m semi anechoic room. The distance between EUT and the field generating antennas were 3 meters, and the floor between these was covered with absorbers. 4.2 EUT (Equipment Under Test): EUT is an AC / DC Power Supply. 4.3 List of ports Power ports: 4.4 230 VAC 50 Hz RF disturbance tests: During the RF field emission test the EUT was rotated in the test chamber and measured with the test antenna both vertically and horizontally. Radiated disturbance was measured from 150 kHz to 2000 MHz. During the radiated disturbance measurements, the EUT was connected to a load at 8, 4 A. 4.5 Immunity tests: The RF field immunity test is performed at 3 meter distance with absorbers on the floor between the transmitting antenna and the EUT. A log periodic antenna is used in the frequency range 80 1000 MHz. A horn antenna is used above 1 GHz. During the RF field immunity test the EUT was exposed at 0 and 180 degrees and to both vertical and horizontal field. During RF immunity test, the EUT was connected to a load at 8,4 A, and both the current consumption and the output voltage level was monitored. 4.6 Performance Criteria IEC 60 945 Performance criteria A The EUT shall continue to operate as intended during and after the test. No degradation of performance or loss of function is allowed, as defined in the relevant equipment standard and in the technical specification published by the manufacturer Performance criteria B The EUT shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed, as defined in the relevant equipment standard and in the technical specification published by the manufacturer. During the test, degradation or loss of function or performance which is self-recoverable is however, allowed, but no change of actual operating state or stored data is allowed. Performance criteria C Temporary degradation or loss of function or performance is allowed during the test, provided the function is self-recoverable, or can be restored at the end of the test by the operation of the controls, as defined in the relevant equipment standard and in the technical specification published by the manufacturer. Manufacturer performance criteria There was no possibility to monitor the quality of the radio interface (TX or RX) during radiated immunity testing. The EUT has an internal telephone switch and the quality of the audio signal was monitored (on a subjective basis as the manufacturer did not provide any objective performance criteria). 5 EMISSION MEASUREMENTS 5.1 Radiated Disturbance at Enclosure Port (TT6080A) Test set up: The test is performed in a semi anechoic chamber with a size of 22 × 13 × 9,5 meters (l × w × h).

The EUT may be resiliently suspended to compensate for weight not capable of being withstood by the vibration table. Provision may be made to reduce or nullify any adverse effect on EUT performance which might be caused by the presence of an electromagnetic field due to the vibration unit. The EUT shall be subjected to sinusoidal vertical vibration at all frequencies between: – 2 Hz to 5 Hz and up to 13,2 Hz with an excursion of ±1 mm ± 10 % (7 m/s2 maximum acceleration at 13,2 Hz); – above 13,2 Hz and up to 100 Hz with a constant maximum acceleration of 7 m/s2. The frequency sweep rate shall be 0.5 octaves/min in order to allow the detection of resonances in any part of the EUT as mounted. A resonance search shall be carried out throughout the test. During the resonance search the EUT shall be externally observed, by unaided visual and aural means, for obvious signs of any resonances of components or sub-assemblies that may affect the integrity of the EUT. Such observations shall be recorded in the test report. If any resonance, as measured by a sensor fixed to the outside of the EUT at the location where obvious signs of resonance have been observed, has a magnitude ratio ≥5 measured relative to the surface where the EUT is fastened, the EUT shall be subjected to a vibration endurance test at each resonant frequency at the vibration level specified in the test with a duration of 2 h. When resonant frequencies with magnitude ratios ≥5 are harmonically related, only the fundamental frequency shall be tested. If no resonance with a magnitude ratio ≥5 occurs, the endurance test shall be carried out at one single observed frequency. If no resonance occurred, the endurance test shall be carried out at a frequency of 30 Hz. Performance check(s) shall be carried out at least once during each endurance test period, and once before the end of each endurance test period. The procedure shall be repeated with vibration in each of two mutually perpendicular directions in the horizontal plane. The requirements of the performance check shall be met.

Positioning of magnetic compasses in ships. Procedure Compass safe distance is the distance between the nearest point of the EuT and the subject compass, where an unacceptable compass deviation occur For a standard compass, the horizontal magnetic flux shall be less than 0.942 mGauss (compass deviation of 5.4°/H). For a steering/standby/emergency compass, the horizontal magnetic flux shall be less than 3.142 mGauss (compass deviation of 5.4°/H). The compass safe distance is measured with a DC milligaussmeter. The EuT is first rotated to determine the worst case direction. Secondly the EuT is moved towards/away from the measurement probe until the required field is measured. The distance is then measured. Measurements are made at 3 EuT conditions: Non-energized (in the magnetic condition received from customer) Non-energized after magnetisation in a 1 Gauss (80A/m) DC field, with a superimposed stabilising 50Hz AC field of 18 Gauss (1430A/m) * Energized and in normal operating condition * Test 2) may be omitted if the application of a strong magnetic field may damage the EuT Instruments used during measurement Instrument list: Magnetometer: Alphalab DC Milligauss (N-4046) (10/09) Magnetization Coil: Nemko HC-1 (N-4216) (NA) AC Magnetometer: Combinova MFM 10 (N-4286) (09/09) DC Magnetometer: Alphalab DC Magnetometer (N-4258) (10/09) Comments No recorded comments.
