22.6 Stranded conductors shall not be consolidated by lead-tin soldering where they are subjected to
contact pressure, unless the clamping means is so designed that there is no risk of bad contact due to
cold flow of the solder.
Consolidation of a stranded conductor by lead-tin soldering is allowed if spring terminals are used;
securing the clamping screws alone is not considered adequate.
Soldering of the tip of a stranded conductor is allowed.
Compliance is checked by inspection.
23 Components
23.1 Components shall comply with the safety requirements specified in the relevant IEC standards, as
far as they reasonably apply.
If components are marked with their operating characteristics, the conditions under which they are used
in the tool shall be in accordance with these markings, unless a specific exception is made.
23.1.1 Capacitors in auxiliary windings of motors shall be marked with their rated voltage and their rated
capacitance.
23.1.2 Fixed capacitors for radio interference suppression shall comply with IEC 60384-14.
23.1.3 Small lampholders similar to E10 lampholders shall comply with the requirements for E10
lampholders; they need not accept a lamp with E10 cap complying with the current edition of Standard
Sheet 7004-22 of IEC 60061-1.
23.1.4 Isolating transformers and safety isolating transformers shall comply with IEC 61558-1.
23.1.5 Appliance couplers other than those used for IPX0 tools shall comply with IEC 60309. Those used
for IPX0 shall comply with IEC 60320.
Where appliance couplers not standardized by IEC are used, the manufacturer shall inform the user in the
instructions for use to connect the tool only by means of the appropriate connector specified by the
manufacturer.
23.1.6 Automatic controls not complying with IEC 60730-1 shall be tested according to this standard, and
additionally, according to 11.3.5 to 11.3.8 and clause 17 of IEC 60730-1. Controls may be tested
separately from the tool.
The tests according to IEC 60730-1 are carried out under the conditions occurring in the tool.
For the tests of clause 17 of IEC 60730-1, the number of cycles to be used are:
- for thermostats, 10 000 cycles of operation;
- for temperature limiters, 1 000 cycles of operation;
- for self-resetting thermal cut-out, 300 cycles of operation;
