40、n accuracy appropriate to the requirements. (At least class 0.2, i.e. 0,2 % of full-scale deflection.) 6.3 Measurement of dimensions Using acceptable measuring instruments, check the dimensions of the lamp for compliance with the requirements of 3.2.1, 3.4, and 3.5. (See also appendices B and C.) 6.

41、4 Aging test Age the lamp in a horizontal position for a period of 1 h at the appropriate test voltage given on the relevant data sheet. Age each filament of a dual filament lamp separately. In the case of dual filament lamps for headlights, age the dipped beam filament first, and in the case of oth

42、er dual filament lamps, age the main filament first. Check for compliance with the requirement of 3.3. 6.5 Colour test Use a spectrophotometer or other equally suitable colour-measuring device to determine the chromaticity co-ordinates of the light emitted by a lamp with a yellow bulb, and check for

43、 compliance with the requirements of 3.6. 6.6 Measurement of initial power and of initial luminous flux Operate the lamp in a horizontal position at the appropriate test voltage given on the relevant data sheet, until the lamp has stabilized. Measure by means of suitable instruments, the initial pow

44、er and the initial luminous flux of the lamp and check for compliance with the requirements of 3.7. SANS 1376-1:2008 Edition 1.6 8 6.7 Life test Mount 15 lamps in a horizontal position with a spacing of at least 50 mm between lamps. (If the sample size is less than 15, use all the lamps in the sampl

45、e.) Operate the lamps at the appropriate test voltage given on the relevant data sheet, using a supply voltage which is regulated within 1 %. (If an a.c. supply is used, it must have a frequency in the range 40-60 Hz.) Operate the lamps according to the relevant switching cycle given below: a) R2 an

46、d H4 lamps. Operate the filaments alternately. Operate the dipped beam filament continuously for 15 h and the main beam filament for 7,5 h in each 24 h period with 45 min “off“-periods between operations. b) P21/5W lamps. Test the filaments separately. In each case switch the lamps off for 15 min tw

47、ice in every 24 h period. Amdt 1 c) P21W lamps. Switch the lamps on and off at a frequency of 1,5 Hz (“on“-time = “off“-time) for a period of 15 s. Leave them off for a further period of 15 s and repeat. =4testofdurationtotallampeachoflifeThe Amdt 1 d) All other lamps. Switch the lamps off for 15 mi
