INTERPRETATION SHEET
This interpretation sheet has been prepared by CISPR subcommittee H: Limits for the
protection of radio services, of IEC technical committee CISPR: International special
committee on radio interference.
The text of this interpretation sheet is based on the following documents:

Interpretation
The requirement in Clause 8 “Measurement uncertainty” of IEC 61000-6-4 Amend. 1 ed. 2.0:
8 Measurement uncertainty
The measurement instrumentation uncertainty shall be determined according to CISPR
16-4-2, where applicable.
NOTE For a given test method, the actual value of U has only to be recorded in the test report if the
lab
value is greater than U .
CISPR
shall be interpreted as follows:
The measurement instrumentation uncertainty shall be calculated and compared with the
budgets defined in CISPR 16-4-2. For each applicable test method, whose instrumentation
uncertainty budgets are higher than those defined in CISPR 16-4-2, compliance with the limits
has to be determined according to CISPR 16-4-2 methodology. This requirement is only
applicable for tests where an uncertainty budget is defined in CISPR 16-4-2.
The additional note was further clarification that there is no need to state in the test report the
laboratory uncertainty budget U if this is less than or equal to the U defined in CISPR
lab CISPR
16-4-2. However, it has to be mentioned in the test report that the instrumentation
measurement uncertainty is determined according to CISPR 16-4-2.
