19、on to compliance with criteria in 8.3, the temperature on any point on theexterior surface of the driver shall not exceed 90C (194F).SI4.3.3 During this test, driver operation shall not be interrupted by the functioning of an integral orexternal protective device (e.g. overtemperature protective dev

20、ices such as thermal links andautomatically resetting (thermostatic) type protectors, electronic protective circuits or overcurrentprotective devices such as fuses), also see 8.3.7.SI5 MarkingSI5.1 A driver that complies with all the applicable requirements for Type IC LED drivers shall be marked“Ty

21、pe IC LED driver”.SI5.2 A driver marked “Type IC LED driver” shall also be marked “For Connections Use Wire Rated for atLeast 90C (194F)” or equivalent.RATIONALE FOR DECISION:This Certification Requirement Decision (CRD) documents the construction, performance and markingrequirements for Type IC LED

22、 drivers. By definition a Type IC LED driver is intended to be integrated intoa recessed type LED luminaire in a manner where the LED driver enclosure will come in contact withinsulation.Luminaire manufacturers can leverage the additional evaluation that has been performed for Type IC LEDdrivers to

23、reduce 1) the work to qualify new recessed Type IC LED luminaire designs, and 2) the work toqualify alternate LED drivers for established Type IC LED luminaire designs.Compliance with these requirements is solely based on the manufacturers request. LED drivers that donot have the Type IC LED driver

24、engineering marking can be integrated into recessed Type IC LEDluminaires, based on end product evaluation and testing (e.g. by using the UL 1598 supplementaryrequirements for recessed luminaires).The construction requirements are limited to designs specified in SI3.1. Other LED drivers designs are

25、notcovered as they are not intended to come in direct contact with thermal insulation.STANDARD NUMBER: UL 8750 -3-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULThe performance requirements limit maximum LED driver case temperatures to 90 C u

26、nder 1) normaltemperature test conditions described in section 8.3 of UL 8750, and 2) Type IC temperature testconditions described in UL 1598 section Recessed luminaires - supplementary requirements.The marking requirements positively identify LED drivers that meet all the criteria and identify mini
