Devices with a length exceeding mm shall be horizontally centered in the test cham- ber.

Dust tests are mainly performed to test functioning of electronic components under extreme environmental conditions. The bottom sae j575 the chamber may be “hopper shaped” to aid 1n collecting the dust.

For sensor systems with lens es that change the diameter of the intercepted light beam before it reaches the actual detector surface, the maximum size requirements shall apply to the total area of the light actually intercepted by the lens surface, The sensor shall be capable of intercepting all direct illumination sae j575 the largest illuminated dimen- sions of the sample device at the test distance.

The purpose of the alternate Water Submersion Test 4. Each sample shall be sae j575 mounted on a test fixture sae j575 its designed operating position and shall include all accessory equip- ment necessary to operate the device in its normal manner. The use of this report i3 entirely voluntary, and its sae j575 and suitability for any particular use, including any patent infringement arising therefrom, is the sole responsibility of the user.

Upon completion of the drain period, the Interior of the test device shall be observed for moisture accumulation. If this 1s not possible, a transition table shall be used to mechanically interface the large test fixture base to the smaller vibrator table. The letters “V” and “H” designate the vertical and horizontal planes Intersecting both the device light source or center of a reflex reflector and sae j575 photometer axis.

Society for Automotive Engineering All sample devices may be tested only to the Dust Exposure Test 4. The formation of dust within the test space is effected by compressed air injection through four special nozzles.

Sae j575 dust is found, the exterior optical surfaces of the device sae j575 be cleaned and the maximum luminous intensity photo- metrically measured anid recorded. If the measured moisture accumulation exceeds 2 mL, the Interior volume of the sample device shall be measured and the results recorded.

The letters “U,” “D,” sae j575 and “R” up, down, left; and fight respectively designate the angular position in degrees from the H and V planes to the photometer as viewed from a lamp, or to the source of illumination as viewed from a reflex reflector. The dust is blown and swirled in upper test space by intensive air movement.

A water spray cabinet with a rotating test platform shall sae j575 used with the following characteristics: Sae j575 with a length exceeding mm saw be horizontally centered In the test chamber. The acceleration component measured shall be in the direction of table travel.

Devices with multiple function combinations shall be tested with all functions simultaneously operating as specified, except for back-up functions.
