The standard to be met in the Japanese standard rain test chamber is "JISD0203-1994 Test Method for Moisture Resistance and Water Resistance of Auto Parts", which is applicable to the test method for moisture resistance and water resistance of auto parts.

Test type	mark	The purpose of the Japanese standard rain test chamber test
Moisture test	M1	Investigate the relative humidity performance of the parts.
Moisture test	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.
Sprinkler test	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.
Water spray test	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.

Test type	Water pressure (gauge pressure) at the sprinkler orifice MPa	The size of the sprinkler orifice	Number of sprinklers or sprinklers	Total water discharge 1/min (minimum)	Water temperature °C	Wetting conditions	Temperature difference between test piece and water (1)°C	Test time	operating
M1	-				Approximately 32	Mixed atmosphere of air, water droplets and water vapor	-	8h	Rotate the test piece around the horizontal axis at a rate of 1.5 revolutions per minute
M2	0.01				About 60		-	1h	-
R1	0.01	Refer to Figure 1	2		Room temperature		-	10min	Refer to note 1
R2	0.003	Refer to Figure 1	2		Room temperature		-	10min
S1	0.10	φ1.2	40		Room temperature		-	30min
S2	0.03	φ1.2	40		Room temperature		-	1h
D1	-				reference Remark 2		-	5min	Immerse to the upper surface of the specimen
D2	-							10min	Immerse the upper surface of the specimen to the depth of 100mm
D3	-							10min

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.
