Add the following new clause 8:
8 Electromagnetic and electrostatic compatibility requirements and test
procedures
8.1 General
8.1.1 This clause specifies requirements for bandpass filters with respect to their immunity to
power- and radio-frequency electromagnetic fields and to electrostatic discharge, and the
permitted radio-frequency electromagnetic emissions, together with test procedures to
demonstrate conformance to the specifications of this standard. Bandpass filters are available
in many different configurations and may be powered by batteries or from external power
supply systems. The technical requirements in this clause are for three bandpass filter
configurations: first group X, for self-contained instruments that are designed primarily for
battery operation; second group Y, for self-contained instruments that incorporate a bandpass
filter facility according to this standard and that are operated from public power supply
systems; third group Z, for bandpass filters that are formed by interconnection of two or more
items of equipment.
NOTE For convenience and consistency, bandpass filter sets are described in this clause as bandpass filters.
8.1.2 The electromagnetic and electrostatic compatibility requirements are equally applicable
for bandpass filters used in residential, commercial and light-industrial environments, or
industrial sites. The requirements of this clause are additional to those contained in previous
clauses and do not alter any of the specifications for bandpass filters contained therein. The
requirements do not apply to bandpass filters complying with this standard manufactured prior
to the publication of this clause.
8.1.3 These requirements are the first attempt at specifying electromagnetic and electrostatic
compatibility requirements for bandpass filters. When wider experience has been gained,
further requirements may be added if found necessary.
8.2 Emission limits
8.2.1 The upper limits on radio-frequency emissions from any apparatus are defined for
compatibility with many different standards, with the limits laid down in table 1 of
CISPR 61000-6-3 forming the basic requirements for bandpass filters in groups X, Y or Z.
These are summarized in annex D.
8.2.2 Bandpass filters in groups Y or Z powered from a public power supply system shall also
comply with the limits for disturbance to the public supply system specified in CISPR 22 for
class B equipment. For bandpass filters, these requirements are summarized in annex D.
61260 Amend. 1 IEC:2001 – 11 –
8.2.3 The instruction manual shall state the mode of operation of, and the connecting devices
(if any) to, the instrument that produces the greatest electromagnetic emissions.
8.3 Electrostatic discharges
8.3.1 Bandpass filters in groups X, Y or Z shall withstand electrostatic discharges of
specified magnitudes. The requirements are those specified in 1.4 of table 1 in IEC 61000-6-1
and are summarized as follows.
– Contact discharges up to 4 kV and air discharges up to 8 kV with both positive and negative
voltages. The polarity of the electrostatic voltage is with respect to earth ground.
8.3.2 IEC 61000-6-1 specifies performance criterion B during and after electrostatic discharge
tests, given as:
"The apparatus shall continue to operate as intended after the test. No degradation of
performance or loss of function is allowed below a performance level specified by the
manufacturer, when the apparatus is used as intended. The performance level may be
replaced by a permissible loss of performance. During the test, degradation of performance is
however allowed. No change of actual operating state or stored data is allowed. If the minimum
performance level or the permissible performance loss is not specified by the manufacturer,
then either of these may be derived from the product description and documentation (including
leaflets and advertising) and what the user may reasonably expect from the apparatus, if used
as intended".
The term “apparatus” means any bandpass filter conforming with this standard.
8.3.3 After each and every electrostatic discharge test is complete, the bandpass filter shall
be fully operational and in a configuration identical to that established before the start of the
electrostatic disch
