Rain Test Equipment
RA-1 / RA-2 / RA-3 / RA-Z
The Rain Test Equipment that tests the water resistance and waterproofness of in-vehicle parts, electrical components, mobile devices, etc. International Protection Code (IP Code) is IPX1, IPX2, IPX3, IPX4, IPX4K, IPX5, IPX6, IPX6K, IPX7, IPX8, IPX9K, supported standards are SAE J575, IEC 60529, JIS C 0920, DIN 40050 (IP-Schutzarten), ISO 20653, JIS Supports a wide range of D 5020, JIS D 0203, and others.
Rain Test Equipment RA-1 / RA-2 / RA-3
Test standard : SAE J575, JIS D 0203
Rain Test Equipment that tests the water resistance and waterproofness of in-vehicle parts such as automobile headlights and blinkers when they are exposed to wind, rain, or spray from the outside. You can easily switch the rotation speed, watering, and fountain of the sample rotary table.
- RA-1 complies and dedicated to SAE J575 Type A.
- RA-2 complies and dedicated to JIS D 0203.
- RA-3 complies with JIS D 0203 - spray test, fountain test, and SAE J575 Type A - water resistance test.
Available customization to control the chamber temperature and water tank temperature.
Rain Test Equipment RA-Z
Test standard : ISO 20653, IEC 60529, SAE J575, JIS D 5020, JIS C 0920
RA-Z tests the waterproof performance of in-vehicle electrical components and mobile products. Depending on the IP protection grade, various IEC, ISO, DIN, JIS tests such as oscillating tube test, drip-proof test, high-pressure injection test, etc. are supported, so please specify before ordering.
- You can easily switch between the rotation speed of the specimen rotary table, the water spray test, and the fountain test.
- Oscillating test operation is self-contained and the oscillating tube radius is customizable.
- The water temperature rise is suppressed by adjusting the water temperature by the overflow method.
Rain Test Equipment RA-Z
Test standard : ISO 20653, IEC 60529, JIS D 5020, JIS C 0920
RA-Z performs a water resistance test to determine the protection class (IP Code) of a large test specimen. Testing of protection classes IPX3, IPX4, IPX5, IPX6 specified in JIS C 0920: 2003 is possible. The operation of the oscillating test is automatic. The maximum allowable radius of the oscillating tube is 1600 mm, and 8 tubes (radius 200/400/600/800/1000/1200/1400/1600 mm) are attached and replaceable according to the test specimen size.
