3General requirements
This guidance is applicable to the relevant clause(s) of a Tc 23 standard covering generalrequirements and/or scope.
Before tests, the specimen is stored for at least 24 h in an atmosphere having a temperaturebetween 15 °C and 35 °C and relative humidity between 45 % and 75 %，except for the test ofClause 7 where lEC 60112 applies.
Accessories shall be so designed and constructed so that, in normal use, their performance isreliable and safe for the user and the surroundings.
Standard conditions for operation in service for electrical accessories complying with theexisting standards should be suitable for use at ambient temperatures not normally exceeding+40 °C, but their average over a period of 24 h does not exceed +35 °C, with a lower limit ofthe ambient air temperature of -5Rc.
