4 Tests
4.1 General
Addition:
Add the following paragraph after the second paragraph of the conformity statement:
Tests needed to support a RISK assessment (see Clause 17) are carried out in the
combinations of conditions and operations determined during the RISK assessment.
4.4.1 General
Addition:
Add the following text at the end of item c):
If the environmental limits of the reference test conditions (see 4.3) do not allow realistic
assessment of SINGLE FAULT CONDITIONS, the test shall be conducted at the least favourable
RATED environmental conditions of the equipment.
4.4.2.2 PROTECTIVE IMPEDANCE
Deletion:
Delete item b) and renumber item c) as item b).
5 Marking and documentation
5.1.3 MAINS supply
Replacement:
Replace the conformity statement with the following:
Conformity is checked by inspection and by measurement of power or input current to check
that the requirements of 5.1.3 c) have been met. The measurement is made at each RATED
voltage range with the equipment in the condition of maximum power or current consumption
as applicable with all accessories and plug-in modules connected. If the input current varies
during the normal operating cycle, the steady-state current is taken as the mean indication of
the highest measured r.m.s. value during a 1 min period of the normal operation cycle. To
exclude any initial inrush current, the measurement is not made until the current has
stabilized (usually after 1 min). Transients are ignored.
5.1.5.2 TERMINALS
Deletion:
© IEC 2016
Delete, in item c), the word “control”.
5.2 Warning markings

Warning markings specified in this standard shall meet the following requirements.
Replacement:
Replace the paragraph prior to the conformity statement with the following:
If the instructions for use state that an OPERATOR is permitted to gain access, using a TOOL, to
a part or location which in NORMAL USE may present a HAZARD, there shall be a warning
marking indicating that the equipment must be placed in a safe state before access. Symbol
14 shall be used for this purpose with the warning text included in the documentation.
Additional symbols may be used to indicate the nature of the HAZARD such as symbol 12, 13,
or 17 as appropriate.
Symbols are the preferred marking method over text warnings. Supplemental text may be
provided adjacent to the symbol.
