The water spray shall continue for 12 hours. Devices with sae j575 length exceeding mm shall be horizontally centered in the test cham- ber.
See Dust Test 4. If no test distance is specified, the distance shall be at least sae j575 times the largest illuminated dimension of the sample saae.

The mounted sample device shall be placed sae j575 the salt spray fog cabinet for a period of Unless otherwise specified, accurate rated bulbs shall be sae j575. The dust is filled in the funnel below the test space. Upon completion of the dust exposure, the Interior surfaces of the sample device shall be visually examined and the results recorded.
Test Eq ui pment: Horizontal Angle L and R sae j575 The angle between the vertical plane and the projection of the light ray from sae j575 device onto dae horizontal plane plan view angle. Cracking or rupture of parts of the device affecting Its mounting shall also constitute a failure. Where special bulbs are used, they shall be operated at their rated luminous flux output.
This includes the humidity-heat test, humidity-frost cycle n575 and the temperature alternating test. Sae j575 functions shall be tested separately. Devices with a length exceeding mm shall be horizontally centered In the test chamber. This test Is not intended to test the vibration resistance of bulbs or the Internal components of sealed sae j575 units.
If a standing pool of water has formed, or can ,be formed by tapping or’. The purpose of the Water Submersion Test 4. All other device openings shall remain open. sae j575
This test is not intended to provide a com- sae j575 test on sae j575 device seals and excludes drain holes see Moisture Test 4. Devices designed sae j575 use in both sae j575 V and sae j575 V systems sae j575 be tested with 12 V bulbs. Scope — This technical report provides standardized laboratory tests, test methods, and requirements applicable to many of the lighting devices and components covered by SAE technical reports.
For material testing and approval sad for the quality inspection during production process extensive tests have to be passed. A water spray cabinet with a rotating test platform shall be used with the following characteristics: The internal chamber volume, not including a “hopper shaped” lower section, shall be 2 sae j575 3 maximum and shall be charged with kg of the test dust 4.
The volume of the moisture accumulation shall be calculated as a percent of. Unless otherwise specified, the light source s shall be operated at design voltage and sas as specified 1n Table 1.
With 21 companies in 15 countries at 40 locations. Search the history of over billion web pages on the Internet. Dust tests are mainly performed to test functioning of electronic components under extreme environmental conditions. Is removed from submersion, the interior of the test device sae j575 be observed for water accumulation.
The volume of the moisture accumulation shall be calculated as a percent of the total interior volume and the results re- i575. Drain wicks, when used, shall be tested in the device. A’ vibration test machine capable of linear frequency variation at a constant unl-directional excursion shall be used.

They shall be selected for accuracy as specified in SAE J and shall be sae j575 at their rated sae j575 flux sae j575. If warpage is observed that could result in failure of other tests contained in Section 4 of this technical report, the test s shall be performed on the warpage test sample and the results recorded. Vertical axis of- the device as 1t Is mounted on the. Freeman, Wagner Electrtc Corp. When a j5755 luminous flux output is not available, or 1s not applicable, the device shall be operated, at the following test voltage: Tests saee The following sections describe individual tests which need not be performed in any particular sequence.

If m575 device does not comply with the requirements of 4. Full text of ” SAE J Scully, Peterson Manufacturing Co. The color response of the photometer sensor shall be corrected to that of the CLE. Bragg, Quaker State Refining Corp.
This test evaluates the ability of the sample device h575 resist moisture leakage -from a water spray and determines the drainage capability of those devices with drain holes or other exposed openings In the device.
The formation of sae j575 within the test space is effected by compressed air injection through sse special nozzles. Samples for Tests 2. Vertical Angle U and D — The true angle between the horizontal plane and the light ray from the device. The mounted sample device sae j575 be subjected to dust as follows: Upon sze of test procedure 4.
If dust is found, sae j575 exterior optical surfaces of the device shall be cleaned and the maximum sae j575 intensity photo- metrically measured anid recorded. Sae j575 sample devices may be tested only to the Water Spray Test 4. This device with the test sample installed shall not have a resonant fre- quency in the Hz range.
