2、 burning. The luminous intensity measurements (in candela) shall be recorded for each of the test points and zones specified for the function of the device under test. This is consistent with SAE J575Changed 4.10.2.2 to reference SAE J1455 instead of SAE J1889. Tests are very similar and was already
3、 referencing J1455 for the temperatures.Added 5.5.1.1 - For any signal and marking device, unless otherwise specified in the applicable SAE document, the minimum luminous intensity (candela) requirement between any two adjacent test points shall be no less than 60% of the lower specified minimum val
4、ue of the two test points on a horizontal or vertical or diagonal line. The specified minimum value is defined by the individual test point value not the zonal value. This is consistent with SAE J5751. SCOPEThis SAE Recommended Practice provides standardized laboratory tests, test methods, and perfo

16、 marking applications. The DSL system is composed of a discharge light source, interconnecting wiring, and a signal or marking lighting assembly.3.2 DISCHARGE LIGHT SOURCEAn electric light source in which light is produced by a stabilized electric discharge through an ionized gas. The light source c

Each sample shall be securely mounted on the test fixture in its design position and shall include all accessory equipment necessary tooperate the device in its normal manner.3
21、.8 SEALED LIGHTING DEVICESA lighting device that does not allow the passage of gas or water between the interior environment and the exterior environment. 3.9 TEST FIXTUREFixture specifically designed to support the device in its designed operating position during a laboratory test.3.10 VIBRATION TE
22、ST FIXTUREA fixture specifically designed to support the device in its operating position during the vibration test. The fixture shall not have a resonant frequency in the test range.4. TESTSThe following sections describe the individual tests which need not be performed in any particular sequence,
23、except as noted in the test procedure. Unless otherwise specified all tests will be done at an ambient room temperature of 25 C 5 C. The completion of the tests may be expedited by performing the tests simultaneously on separately mounted samples. However, it is recommended that the design of each d
