A ratio of 3:1 or less is desirable and may be specified by the user to reduce burning hours and redu
31、ce attached load energy consumption. 5ANSI C136.24-2004 (R2010) 12 Qualification test procedures 12.1 Humidity test The control assembly shall be exposed to 96% relative humidity at 50C for 168 hours and operated at rated voltage and load. Controls shall be illuminated for 12 hours at 1070 Lux (100
32、Fc) and 12 hours below 1 Lux (0.1 Fc) for 7 cycles. Within 1 minute of removal from the humidity, the control shall be subjected to the dielectric withstand test described in Clause 12.6. Within 15 minutes from removal from humidity, the control shall meet the light level requirements of Section 11.
33、 12.2 Rain test The control assembly shall be subjected to the rain tightness test described in ANSI/UL773A. Only the nipple and window of the button are required to be exposed to water. Within 5 minutes of completion of test, the control shall be tested and shall meet the dielectric withstand test
34、described in Clause 12.6. Within 15 minutes from removal from humidity, the control shall meet the light level requirements of Section 11. 12.3 Surge test The open circuit surge voltage shall have a 6,000 V peak amplitude and a 1.2 s x 50 s wave shape. The voltage wave shall be synchronized with the
35、 AC power lines and shall be initiated from 30 to 60 or 225 to 285 after the 60 Hz voltage has gone through zero from positive to negative. The short circuit surge current shall be 3,000 A peak and have an 8 s x 20 s wave shape. Available ac follow current shall be 1,000 A. All values are 5%. To per
36、form the test, the control window is exposed to less than 1 Lux (0.1 Fc). The control is subjected to two surges at 30 to 60, one at 255 to 285. The control window is then exposed to over 1,070 Lux (100 Fc) and subjected to two surges at 30 to 60, one at 255 to 285. Time between surges shall be two
37、minutes. Surges shall be applied between LINE and NEUTRAL or COMMON lead. LOAD lead shall not be connected. The test is run at 25 5C with the control at any convenient position. After this test, the control shall operate per Section 11 and Clause 12.6. 12.4 Load test, 120 V Controls shall pass the f
38、ollowing minimum design tests. Since the tests may degrade controls, new controls may be used for each test. 12.4.1 Tungsten test The control shall be connected to a load of a single 500 W mogul base tungsten filament lamp operated at 120 Vac, 60 Hz. The test setup shall be capable of supplying an i
39、nstantaneous inrush current to the lamp of at least 45 A. The control shall be cycled at a rate no faster than 1 ON/OFF cycle in 6 minutes by subjecting the control window to less than 0.1 Fc for 1.5 minutes, gradually increasing light to 20 Fc over a period of 1 minute, maintaining light at 20 Fc f
40、or 2.5 minutes and then gradually decreasing illumination to below 0.1 Fc over a period of 1 minute. If the design of the control is such that it will respond to rapidly changing light levels, the test may be done below 1 Lux (0.1 Fc) for 10 seconds and over 214 Lux (20 Fc) for 50 seconds. The contr
41、ol shall be capable of switching the load for 3,650 operations with no more than 5 failures to operate. 12.4.2 Inductive load test The same procedure as Clause 12.4.1 shall be used, except the load shall be an inductor that draws 6.25 A at a power factor of 0.4-0.6 at 120 Vac. 6ANSI C136.24-2004 (R2
42、010) 12.4.3 Capacitive load test The same procedure as Clause 12.4.1 shall be used, except a 60 F 10% ac capacitor is added in parallel with the inductor. 12.4.4 Steady state load test The control shall be connected to a resistive load equal to 80% of its rated current at an ambient of 40C for 48 ho
43、urs with less than 1 Lux (0.1 Fc) on the control window. After removal from load, the control shall pass Sections 11 and 12. 12.5 Load test, other voltages Controls rated for voltages other than 120 Vac shall be tested as in Clause 12.4, except load current will be adjusted so that load wattage and
44、volt-amperes are the same as in Clauses 12.4.1, 12.4.2, and 12.4.3. Test(s) will be performed at minimum and maximum rated voltage. 12.6 Dielectric withstand test The control shall be mounted with nipple through a hole in a metal plate. The dielectric withstand test shall be made by applying the tes
45、t potential between: 1) All control leads and 2) the metal plate and any exposed conductive parts. The test is for 2.5 minutes with a potential of 2,500 volts, 60 Hz. Failure is defined as insulation breakdown or control not operating per Section 11 after this test. 7NATIONAL ELECTRICAL MANUFACTURERS ASSOCIATION 1300 NORTH 17TH STREET, SUITE 900 ROSSLYN.
