IEC 62031-2018 pdf free.LED modules for general lighting – Safety specifications.
4.3For non-integrated LED modules and semi-integrated LED modules,all electricalmeasurements，unless otherwise specified, shall be carried out at voltage limits (min/max),current limits (min/max) or power limits (min/max) and minimum frequency, in a draught-freeroom at the temperature limits of the allowed range specified by the manufacturer.Unless themanufacturer indicates the most critical combination， all combinations (min/max) ofvoltagelcurrent/power and temperature shall be tested.
4.4 For integrated LED modules，the electrical measurements shall be carried out at thetolerance limit values of the rated supply voltage.
4.5Integral LED modules not having their own enclosure shall be regarded as integralcomponents of luminaires according to lEC 60598-1:2014,0.5.1.
4.6In addition to the requirements of this document，independent LED modules shallcomply with lEC 60598-1:2014 and lEC 60598-1:2014/AMD1:2017.
4.7lf the LED module is a factory sealed unit, it shall not be opened for any tests. In caseof doubt based on the inspection of the LED module and the examination of the circuitdiagram,and in agreement with the manufacturer or responsible vendor，such speciallyprepared LED modules shall be submitted for testing so that a fault condition can besimulated.
4.8For LED modules with integrated controlgear providing SELV, the requirementsaccording to lEC 61347-1:2015 and lEC 61347-1:2015/AMD1:2017, Clauses L.5,L.6,L.7,L.8,L.9,L.10,and L.11 apply.
5 General test requirements
5.1 Tests according to this document shall be type tests.
NOTE The requirements and tolerances in this document are related to testing of a type-test sample submitted bythe manufacturer for that purpose.
5.2The test shall be carried out at an ambient temperature of 10 °C to 30 °C. lf themanufacturer specifies a different ambient termperature,this shall be used as testtemperature.
5.3Unless otherwise specified, the type test shall be carried out on one sample consistingof one or more items submitted for the purpose of the type test.
ln general，all tests shall be carried out on each type of LED module or, where a range ofsimilar LED modules is involved, for each power in the range or on a representative selectionfrom the range, as agreed with the manufacturer.
5.4lf the light output has substantially changed， the LED module shall not be used forfurther tests.
NOTE Usually, a value of 50 % indicates irreversible changes in the LED module.
5.5Testing of integral LED modules not having their own enclosure shall be done as part ofthe luminaire as far as applicable.IEC 62031 pdf download.
