Question:
Is the plastic material fixing the plug of a battery pack of a hand-held power tool evaluated as insulation material and subjected to the glow-wire tests in 30.2.3.1 and 30.2.3.2, even if the battery pack is not included in the tests of IEC 60335-2-29 if the rated output current is less than 20A?
Is IEC 60335-2-29 also applicable to a combined battery charger and battery pack, if the battery pack is a special one (e.g. for hand-held tools) only chargeable by the battery charger and with safety relevant components (e.g. thermal protector) inside.
Decision:
1.- For the figure, it is clear in the standard that sub-clauses 30.2.2 and 30.2.3 applies to any plastic material supporting connection regardless the distance to the point of the connection.
0 i6 `  R8 d& k7 e2.- If the battery is special for the appliance in such a way that it is needed for compliance with the requirements of the standard then, it shall be considered as a part of the appliance and shall comply with all relevant clauses of the appliance standard.
