【文章內(nèi)容簡介】 hall be tested （ SELV部分可以不需要絕緣） ?Joints and junctions in internal wiring, excluding terminations on ponents, shall be provided with an insulating covering no less effective than the insulation of the wiring（連接處的絕緣要線材絕緣） Internal wiring PROVISION FOR EARTHING（接地規(guī)定） ? A current 10 A, a noload voltage 12 V, shall be passed between the earthing terminal or earthing contact and each of the accessible metal parts in turn.（地線端和任意可接觸的金屬部件間） ? the resistance shall not exceed 0,5 Ω ? identified by the green and yellow colour bination shall only be connected to an earthing terminal. PROTECTION AGAINST ELECTRIC SHOCK Test to establish whether a conductive part may cause an electric shock （導(dǎo)電部件是否會引起觸電） ? Where the voltage measured according Clause exceeds the limit value, the touch current shall not exceed:接觸電流不得超過 ? for .: 0,7 mA (peak)。 ? for .: 2,0 mA. No access to live parts with the standard test finger is permitted when the luminaire has been assembled for normal use and（標(biāo)準(zhǔn)測試指不會接觸到帶電部件） – for portable, settable and adjustable luminaires, no access to basic insulated parts with the standard test finger is permitted, （對于可移動、設(shè)置和調(diào)節(jié)的燈具，標(biāo)準(zhǔn)測試指 沒有可接觸的基本絕緣部件） – for other types of luminaires, there shall be no access to basic insulated parts from the outside of the luminaire by means of a 216。,50 mm probe （ 其他的燈具 ， 216。,50 mm沒有可接觸的基本絕緣部件） Basic insulation may be accessible when the luminaire is opened for lamp or starter replacement （用于換燈泡或啟輝器時，基本絕緣允許被接觸） ENDURANCE TEST AND THERMAL TEST Endurance test （耐久測試和熱測試） ? The ambient temperature within 177。2 176。C of (ta + 10) 176。C during the test ? The luminaire shall be tested for a total duration of 168 h ， shall be applied for the first 21 h and disconnected for 3 h of each cycle. （持續(xù)測試168H,21h點亮， 3h熄滅） ? The circuit condition in normal operation for the first six cycles, and as in abnormal operation for the seventh cycle（前面 6個周期進行正常測試，后面1個周期進行非正常測試） ? For luminaires for which there is no abnormal, the total test duration shall be 240 h （一般燈具做 240H,帶有馬達的需要做非正常的測試） ? the supply shall be 1,10 177。 0,015 times the rated voltage or the maximum of the rated voltage range. （ 測試電壓： Vrated ） Compliance： 燈具不能損壞，標(biāo)簽要清晰 The marking of the luminaire shall be legible。 Thermal test (normal operation) （正常熱測試） ? The luminaire shall be tested in a draughtproof enclosure（無風(fēng)環(huán)境）
