The purpose of the Japanese standard rain test chamber test

Moisture test

M1

Investigate the relative humidity performance of the parts.

M2

Investigate the performance of parts under high temperature and high humidity conditions.

Sprinkler test

R1

Investigate the performance of parts in contact with water droplets.

R2

Investigate the performance of parts under indirect exposure to wind, rain or splashing water.

Water spray test

S1

Investigate the performance of parts under indirect exposure to wind, rain or splashing water.

S2

Investigate the performance of parts under strong water conditions.

Water immersion test

D1

Investigate the performance of parts under temporary water immersion.

D2

Investigate the performance of parts that are often immersed in water or parts that are completely waterproof.

D3

Investigate the performance of special-purpose waterproof parts.

The test method of the Japanese standard rain test box: test the specified Japanese standard rain test box, install the test piece under the normal use state, and conduct the test under the following conditions to investigate the moisture resistance, water resistance, drainage or performance of the parts Changes and so on.

Note (1) The temperature difference refers to the occasion where the temperature of the water is higher than the temperature of the test piece.
 
Remark 1: Regarding the sprinkler test and the sprinkler test, install the test piece at a distance of about 400mm from the drain pipe with sprinklers or sprinklers, centered on the XX axis, and rotate the drain pipe at a rate of about 23 words per minute.

In addition, the test piece was rotated around the vertical axis at a rate of about 17 times per minute. However, the rotation of the test piece can be omitted based on the negotiation among the delivery parties.
 
Yuexin-Focus on the development and production of the Japanese standard rain test chamber, and look forward to every communication with you.
