4.2.1 Air-cooled xenon arc lamp bZxz.net
Room-cooled indicator, should meet the following conditions) The light source is installed in a good ventilation case, the light source is one or more arcs, the number and size of the arcs depend on the form used:
b) Method light film (glass retention rate> Place a light source sample to monitor you standard question, so that the ultraviolet spectrum is fixed. Use a filter night I about transmittance at 38m--750mm less than %, its absorption film installation, transmittance at 31m~32 should be reduced:
; Full heat! , the spectrum contains three infrared discs, and the heat plate is required to reduce the concentration of the control standard. The test standard is low in effectiveness. According to GB8432-17, the wet standard sample should be of non-color, grade 6, and the effectiveness is obtained by using a 5~8 grade blue semi-standard pool in the cooling equipment. The light intensity on the exposed surface should not exceed 10% of the normal value:
f! The distance between the lamp and the sample and the standard surface of the flow piece should be the same. QB/T2727—2CCS
4. 2. 2 Water-cooled xenon arc lamp
Eastern blood arc lamp, the box should be combined with the following creation strips
a) the light source is flat and the center axis of the frame is selected, the frame 1) Ⅲ is reversely rotated, the frame is two-layer or three-layer Si Jin·type non-series:
blood heart Sheng Meng installed internal filter grid and heart full of external light resources: can control the color of the single sense, the cabinet is also smooth and long: [cooling adjustment: how much cooling is required to stop condensation on the lamp,) the factory guarantees that both the water and the cooling are large ions, this contains one, the total amount of water is not more than 204.2.3 irradiation to monitor the meter
worker love oxygen lamp, light milk love atmosphere lamp pull the reading time and the number of changes, should be through the monitoring meter system, that is, before the construction of the light! The incident energy level is shaped by the position of the test sample, and the British 424 black standard intensity meter (BSTS) is used to test the film. The temperature is not equal to the temperature of the film. The thermal conductivity of the film is good. The remaining core reason is that the white board is made to absorb heat: the surface is excited by a layer of black paint, that is, the energy can be transported to at least the active absorption in the infrared region or within the test column.

and the degree of improvement This product has a test, and the symptoms of low sample quality and no test equipment are selected. The test order will be incorrect. The size of the test order can be formed into a blue sheep standard shot. The price is detailed and the second error is caused by the
should be set up to ensure that the chief engineer can handle the delivery of the work properly. The lamp is installed on the station. 6.1
6.2 The test ladder selected for light transportation is distinguished and installed to make the sound of the test equipment away from the sample type. On the rack, the empty claw white strong card is used. - Research points. 6.3 Test the control borders on each section: to obtain the current distribution and cumulative load of the standard thermometer flow 4 product certification equipment exposure, avoid continuous operation test, the final non-product must be clear of the atmosphere lamp or because the lamp support can be used inside and outside the light sheet giant this person uses the Shenzhen collection belt to get the end of the replacement

Fang Bi Shi Men Ying can consolidate the standard The annual block test patience annual standard learning method to determine the color change concentration of the test point. Method 2, let the inspection area for the most and the standard number of control learning increase week 5 some aromatic connection topic match the predetermined wet right relaxation A, the light fastness color rate evaluation || tt || 1 removed all the strips, the test table blue beauty on the test side of the recognized person my mountain area:! The type is a small bottom area, in order to consider a small state of the area of ​​​​expansion. In the active lighting Yu Ren 1, and the corresponding color must be compared with the color
7.1.1 according to method 1 after the test
light fastness package fastness! Article, the color of the standard is evaluated, such as the blue standard: frequency, not this detailed grade, such as grade, such as the sample product does not show the feedback in the adjacent color single standard group, then the product center grade, for example 56 grade. If you change the most flower effect north mountain small temperature grade, you can take the average consumption of its wear technique as 0 1/127272003
is the color half of the test: the closest half-level to the whole level is shown, the level of the charm of the west, change to three, delete the quality of the half or the whole level.
1.2 According to method 2, after the test, evaluate the excess color standard, evaluate with the blue Xin Ping standard, the performance of the primary school is unknown, the period of positive light is determined as "micro intention\, if the test changes "Performance standard, then the color fastness should be "unsatisfactory" 7.1.3 According to method 3, evaluate the change of the sample after the test. If the color bar is at a certain level on the color card, the color development should be half as "unsatisfactory". 2: For each sample with a similar color (the number is M), the aperture of the sample is low and the color is eliminated in the wool machine. This is to avoid the need for accurate color detection and the correct light number change when comparing the 3 samples. When the time is short, the evaluation should be conducted in a normal room with a rate of 24
7.4 Thank you for the color change of the sample, before the color change of the intermediate teaching seat, the number of notarization tests, for example 6, P3.4)
