Any other relevant information: EUT 6 denotes that the printer switched mode power supply was equipment under test number 6 out of a total of 10. During the tests the power supply was subjected to a number of load conditions (25, 50 and 100%), which were set using an external load box consisting of capacitor and resistors. This was built by York EMC Services Ltd as part of an overall project to study the EMC emissions from switched mode power supplies and similar switched electronic load controllers under different load conditions.

comparisons could be made with a number of similar EUTs.

Note 3: Conducted emission measurements made in the frequency range 9kHz to 150kHz were

compared against limit line in EN55015:2000+A1:2001.

Note 4: The customer requested a class D limit for harmonic emissions for in order direct

comparisons can be made between items for the purposes of the investigation, a common limit was

used to test all items.

2.2.2 Immunity

No immunity testing was requested.

Note 1: EUT 6 was tested was tested in two states in order to cover any confusion in the standard regarding how to test the EUT, either by plugging the EUT directly into the LISN or with a 1m cable attached. (See Appendix 7):

(State 1: Plugged directly into LISN)

(State 2: 1m extended cable attached to EUT before plugged into LISN)

5.10 Appendix 10 Reporting the results

Case A The equipment complies with the stated specification of the measured points, due allowance having been made for the uncertainty of the measurements. It may be deemed as a pass. Case B The measured result is below the specification limit by a margin less than the measurement uncertainty; it is therefore not possible to state compliance based on the stated level of confidence. However the result indicates that compliance is more probable than non-compliance with the specification limit. It is a likely pass but within the measurement uncertainty. Case C The measured result is above the specification limit by a margin less than the measurement uncertainty; it is therefore not possible to state compliance based on the stated level of confidence. However the result indicates that non-compliance is more probable than compliance with the specification limit. It is a likely fail but within the measurement uncertainty. Case D The equipment does not comply with the stated specification of the measured points, due allowance having been made for the uncertainty of the measurements. It may be deemed as a fail.
