In industrial product reliability testing, rain spray test chamber is the core tool to verify the waterproof performance of the equipment. ip protection level (international protection level code) through the solid and liquid protection ability grading, which ipx6, ipx6k, ipx9, ipx9k and other liquid protection level of the test need to rely on the rain spray test chamber accurate control parameters. The following from the test equipment, conditions and standards to analyze the differences.
IPX6 (strong water spray test)
Rain spray test chamber configuration: nozzle caliber 12.5mm, water flow (100 ± 5) L / min, pressure 100kPa, water spray distance 2.5m ~ 3m, test time 3 minutes.
Core features: suitable for high-flow high-pressure water spraying scenarios, rain spray test chamber needs to be equipped with high-capacity water pump system to meet the demand for continuous water flow.
IPX6K (extreme high pressure water spray test)
Rain spray test chamber configuration: nozzle caliber 6.3mm, water flow (75±5) L/min, pressure 1000kPa, water spray distance 2.5m~3m, test time 3 minutes.
Core features: Although the water flow is lower, but the pressure is raised to 10 times, the need for rain spray test chamber integrated ultra-high pressure pump body, the equipment sealing requirements are higher.
Difference summary: IPX6 focuses on large flow impact, IPX6K emphasizes the very high pressure penetration, rain spray test chamber needs to be adapted to different water pressure system according to the test level.
IPX9 (high temperature and high pressure jet)
Recommended rain spray test chamber configuration: water temperature 80 ± 5 ℃, pressure 800010000kPa, water flow rate of 15 ± 1L / min, nozzle distance 17525mm, the sample stage speed 5 ± 1r / min, 4-angle cyclic jetting (30 seconds per angle).
Core features: rain spray test chamber needs to have a high temperature and constant temperature system, and support dynamic angle adjustment, simulating the harsh steam cleaning environment.
IPX9K (German standard high-pressure injection)
Rain spray test chamber configuration: the parameters are the same as IPX9, but the jetting distance is adjusted to 100~150mm (refer to DIN40050 standard).
Core features: test logic is the same as IPX9, the difference lies in the standard system (GB/T4208 vs DIN40050), the waterproof test box needs to be compatible with multi-standard parameter preset function.
Difference summary: the two test conditions are highly consistent, IPX9K more focused on the automotive industry, German standard certification, rain spray test chamber needs to meet the precise control of different spray distance.
Pressure and flow control
IPX6K 1000kPa ultra-high pressure, IPX9K 10,000kPa high temperature and high pressure, the rain spray test chamber is required to use stainless steel reinforced piping and high-precision pressure sensors.
Dynamic simulation capability
Modules such as multi-angle spray nozzles and rotating sample stages need to be integrated into the rain spray test chamber to ensure that the test covers all surfaces of the equipment.
Standards compatibility
Support IEC 60529, ISO 20653 and other standard parameters preset, a rain spray test chamber can meet the IPX6 to IPX9K full grade test.
IEC 60529-2013: the core basis for the protection level of general-purpose electronic equipment, rain spray test chamber needs to meet its nozzle size, water pressure and other specifications.
ISO 20653-2013: automotive electronics special standards, IPX9K test need to choose the rain spray test chamber to support DIN40050.
