Rain Chambers for Moisture Ressistance and ip Water Proof Testing Electronics
What is a Rain Test Chamber ?
Designed to simulate a soaking, rainy environment for rain test per
as IEC 60529, Rain/water Spray Test Chambers from ATMARS are mainly used for
car, head lamps, tail lights, and wiring harnesses making them
ideal for conducting a water spray test.
The Rain Test Chamber features a self-contained water recirculation system that eliminates the cost and inconvenience of plumbing in a facility water supply. Water is injected into the test enclosure through specifically-sized nozzles. Flow meters with adjustment valves supply the water spray at specified flow parameters. A rotating test platform can be incorporated in the Water Spray Test Chamber to promote even moisture distribution over the surface of the products under test.
ATMARS's Rain Test Chambers are available in both top and front-opening configurations. ATMARS has the engineering design capabilities and experience to customize rain test chambers to meet special configurations or performance specifications.
| IP Code Second digit: Liquid Ingress Protection | |||
| Level | Protection against | Effective against | Details |
| 0 | - | - | - |
| 1 | Dripping water | Dripping water (vertically falling drops) shall have no harmful effect on the specimen when mounted in an upright position onto a turntable and rotated at 1 RPM. | Test duration: 10 minutes Water equivalent to 1 mm rainfall per minute |
| 2 | Dripping water when tilted at 15° | Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle of 15° from its normal position. A total of four positions are tested within two axes. | Test duration: 2.5 minutes for every direction of tilt (10 minutes
total) Water equivalent to 3 mm rainfall per minute |
| 3 | Spraying water | Water falling as a spray at any angle up to 60° from the vertical
shall have no harmful effect, utilizing either: a) an oscillating
fixture, or b) A spray nozzle with a counterbalanced shield. Test a) is conducted for 5 minutes, then repeated with the specimen rotated horizontally by 90° for the second 5-minute test. Test b) is conducted (with shield in place) for 5 minutes minimum. | For a Spray Nozzle: Test duration: 1 minute per square meter for at least 5 minutes[4] Water volume: 10 litres per minute Pressure: 50–150 kPa For an oscillating tube: Test duration: 10 minutes Water Volume: 0.07 l/min per hole |
| 4 | Splashing of water | Water splashing against the enclosure from any direction shall have
no harmful effect, utilizing either: a) an oscillating fixture, or
b) A spray nozzle with no shield. Test a) is conducted for 10 minutes. Test b) is conducted (without shield) for 5 minutes minimum. | Oscillating tube: Test duration: 10 minutes, or spray nozzle (same as IPX3 spray nozzle with the shield removed) |
| 5 | Water jets | Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects. | Test duration: 1 minute per square meter for at least 15 minutes Water volume: 12.5 litres per minute Pressure: 30 kPa at distance of 3 m |
| 6 | Powerful water jets | Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects. | Test duration: 1 minute per square meter for at least 3 minutes Water volume: 100 litres per minute Pressure: 100 kPa at distance of 3 m |
| 6K | Powerful water jets with increased pressure | Water projected in powerful jets (6.3 mm nozzle) against the enclosure from any direction, under elevated pressure, shall have no harmful effects. Found in DIN 40050, and not IEC 60529. | Test duration: at least 3 minutes[citation needed] Water volume: 75 litres per minute Pressure: 1000 kPa at distance of 3 m |
| 7 | Immersion, up to 1 m depth | Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion). | Test duration: 30 minutes - ref IEC 60529, table 8. Tested with the lowest point of the enclosure 1000 mm below the surface of the water, or the highest point 150 mm below the surface, whichever is deeper. |
| 8 | Immersion, 1 m or more depth | The equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects. The test depth and duration is expected to be greater than the requirements for IPx7, and other environmental effects may be added, such as temperature cycling before immersion. | Test duration: Agreement with Manufacturer Depth specified by manufacturer, generally up to 3 m |
| 9K | Powerful high temperature water jets | Protected against close-range high pressure, high temperature spray
downs. Smaller specimens rotate slowly on a turntable, from 4 specific angles. Larger specimens are mounted upright, no turntable required, and are tested freehand for at least 3 minutes at distance of 0.15–0.2 m. There are specific requirements for the nozzle used for the testing. This test is identified as IPx9 in IEC 60529. | Test duration: 30 seconds in each of 4 angles (2 minutes total) Water volume: 14–16 litres per minute Pressure: 8–10 MPa (80–100 bar) at distance of 0.10–0.15 m Water temperature: 80 °C |
| Note: all tests with the letter "K" are defined by ISO 20653 (replacing DIN 40050-9) and are not found in IEC 60529, except for IPx9 which is the same as the IP69K water test. | |||
Features
Scientific design allows the chamber to provide a realistic
simulation of dripping, drenching, splashing, sprinkling water and
other environments.
More than 1000 holes uniformly distributed on the top so that water
will be sprayed evenly.
Using advanced and comprehensive control system, as well as
frequency conversion technology, in which the rainfall, the
rotation angle of the sample rack, the swing angle of the water
swing lever and the water spray, swing frequency can be
automatically adjusted
Chamber interior/exterior are made of high quality stainless steel
plates
Large area visual glass door for easy observation of interior
specimen status
Using imported speed control inverter to ensure standard testing
procedures
The chamber bottom installed high quality fixed PU casters for
flexible mobility
With 270 degrees swing tubes and 360-degree rotating rod
sprinklers, there are no dead ends for specimen raining test
