INTERPRETATION SHEET 1
This interpretation sheet has been prepared by subcommittee CISPR F: Interference relating
to household appliances tools, lighting equipment and similar apparatus, of IEC technical
committee CISPR: International special committee on radio interference.
The text of this interpretation sheet is based on the following documents:
FDIS Report on voting
CIS/F/703/FDIS CIS/F/707/RVD

Interpretation Sheet 1 to CISPR 14-1: Interpretation of subclause 5.4.2.4 of CISPR 14-
1:2016 on the upper quartile method for the evaluation of clicks

Introduction
The evaluation of clicks has to be performed at four frequencies while the determination of the
click rate N is made only at two frequencies. The application of the upper quartile method at
the frequencies 150 kHz and 500 kHz is clear, while the situation is unclear for the
frequencies 1,4 MHz and 30 MHz. This interpretation sheet is intended to clarify this matter.
The click measurement procedure is under revision in CISPR/F WG1 and will be updated in
the next amendment to CISPR 14-1:2016.
Question
How should the upper quartile method be applied at the frequencies 1,4 MHz and 30 MHz?
Interpretation
Each of the following two interpretations is valid.
ICS 33.100.10
 IEC 2017
Interpretation 1:
The number of clicks at 1,4 MHz and the number of clicks at 30 MHz which exceed the limit,
L, for continuous disturbances during the observation time, T, are measured. The number of
clicks at 1,4 MHz and the number of clicks at 30 MHz exceeding L are allowed to be one
q
quarter of the number of clicks counted at each respective frequency.
Interpretation 2:
The number of clicks at 1,4 MHz and the number of clicks at 30 MHz which exceed the limit,
L, for continuous disturbances during the observation time, T, are not measured but are
assumed to be equal to the number of clicks counted at 500 kHz during the observation time
T. The number of clicks at 1,4 MHz and the number of clicks at 30 MHz exceeding L are
q
allowed to be one quarter of the number of clicks counted at 500 kHz.
In any situation where it is necessary to verify the original measurement, the assessment
method (interpretation 1 or 2) originally chosen shall be used in order to ensure consistency
of the results.

Interpretation Sheet 2 to CISPR 14-1: Interpretation of subclause A.4.11 of CISPR 14-
1:2016 on the assessment of irons with steam generator

Introduction
Subclause A.4.11 of CISPR 14-1:2016 defines the testing conditions for irons (dry or steam),
but there are no instructions regarding the steam production.
Question
How to set the steam function of irons during CISPR 14-1 emission tests?

ICS 33.100.10
 IEC 2017
Interpretation
When measuring disturbances from irons, if the iron has a continuous steam function, it shall
be operated in this mode only and use a sufficient amount of water to facilitate continuous
steaming for the duration of the test.
