22、 and U2045 % or more when tested in accordance with 6.6. 4.7 Temperature rise of film The temperature rise of film shall, when tested in accordance with 6.7, be as follows : a 65 K or under when light source is incandescent lamp or halogen lamp. b) When the light source is a discharge lamp such as x
23、enon lamp or metal halide lamp, the description shall be given on the instruction manual of projector and the like as to the attention to be paid to temperature rise. 5 Construction and function The construction and function of projectors shall be as follows : Under the standard operation conditions
24、, the projectors shall endure the con- tinuous projection for one hour or more. Leakage current shall be 1 mA or under when operating under normal service condition and measuring by connecting the resistance of 1 Ksz between the non- charged metallic part liable to be touched by human body and the e
25、arth. Insulation resistance shall be 1 MQ or more when measuring the insulation resistance between the non-charged metallic part and power source terminal by means of 500 V insulation-resistance meter. After the leakage current test and insulation resistance test, when applying alternating voltage o
26、f 1 O00 V for one minute continuously between the live part and the non-charged part liable to be earthed, the projectors shall withstand it. This test may be carried out by applying alternating voltage of 1200 V for one second. Ordinary temperature rise shall be that, when operating continuously ap
27、plying the voltage equal to the rated voltage of the frequency equal to the rated fre- quency under the ordinary service condition and the temperature rise on each part becomes approximately constant(), the temperature measured on each part shall be the values given in Table 3 or lower. Note (I) The
28、 time when the temperature rise becomes approximately constant is a state where the difference of temperatures in 30 minutes is 0.5 K or under.

36、red at the source socket of the projector shall be within a range of the rated voltage k0.5 %. For the projectors the rated voltage of which is shown with its range, its median shall be taken as the rated voltage. 2) In the case of alternate current, the frequency shall be near constantly the sinewa
37、ve of 50 Hz or 60 Hz. c) Meters to be used in the tests shall be as follows : i) Electric meters shall be of Grade 0.5 or finer specified in JIS C 1102-2 or those equivalent or superior thereto in precision. 2) Illuminance meters shall be those specified in JIS C 1609 or those equiva- lent or superi
38、or thereof in precision. d) Projection at the time of test shall be as follows : i) Place a screen of white colour vertically to the optical axis of projection and carry out the test in a way that the projection image plane becomes 1.0 m in transverse width. The projectors which use its built-in scr
39、een only shall be tested using its built-in screen, 2) Projectors equipped with electric bulb position regulating device shall be tested after the regulation at its position. 3) Projectors equipped with electric bulb transfer switch shall be tested on each electric bulb. 4) The tests shall be carrie
40、d out in such a way that the screen is not affected by other light than the projected light. 6.2 Resolution test Resolution shall be tested as follows : a) Project the test chart specified in JIS B 7181 and focus so that the image of marks of the test chart becomes clearest in the whole image plane.
41、 b) As regards the resolution of the projecting bias, observe the projected screen approaching to it and read the maximum value at which the images of marks in the directions of two stripes can be readily recognized to be re- solved. c) The resolution shall be tested placing the image plane or the l
42、onger side of the aperture horizontally. For the projectors capable of projecting in both vertical and horizontal directions, the test shall be conducted taking the longer side in both direc- tions. d) Lenses of variable focal length shall be tested at the positions of the short- est and the longest
43、 focal lengths.
