Testing & Laboratory

Trust is good, control is better - best in our own laboratory

Absolute reliability and permanent protection of installed components against harmful environmental influences are the focus of our daily work. In order to ensure that our enclosures deliver what we promise, we test them for their forthcoming tasks. In addition, we also test individualised enclosure solutions including built-in electronics for our customers. We carry out the following tests in our in-house laboratory:

IP protection class tests: Dust protection (DIN EN 60529)

For the dust protection test in accordance with protection classes IP5X and IP6X enclosures are tested in a dust chamber for a defined period of time. A vacuum is created inside the enclosure, with talcum powder constantly stirred up within the test chamber. The enclosure is opened after the test cycle and no talcum powder must have penetrated, despite the negative pressure generated.

Protection class IP5X:

Vacuum: with or without 20 mbar
Test duration: 8 hours

Protection class IP6X:

Vacuum: with 20 mbar
Test duration: 8 hours

IP protection class tests: Water protection / (hot) jet water / submerging / (DIN EN 60529)

For the water protection test according to IP X5, X6, X7, X8 and X9K the enclosure is tested using our test systems according to the defined parameters. We regulate the water temperature and can install different nozzles to control the water flow and water pressure. For our customers, we test fully installed products to avoid failures due to water ingress.

Protection class IPX5:

Protection against jet water
Test with jet nozzle Ø = 6.3 mm
Water flow rate: 12 l/min
Water pressure: 30 kPa
Water temperature: Difference not more than 5°C to the enclosure
Distance between enclosure surface and water nozzle: 2.5 - 3.0 m
Test duration: 3 min.

Protection class IPX6:

Protection against jet water
Test with jet nozzle Ø = 12.5 mm
Water flow rate: 95 - 105 l/min
Water pressure: 100 kPa
Water temperature: Difference not more than 5°C to the enclosure
Distance between enclosure surface and water nozzle: 2.5 - 3.0 m
Test duration: 3 min.

Protection class IPX7:

Protection against temporary immersion in water
Test by complete immersion
Deepest point of the enclosure 1 m below the water surface
Water temperature: Difference not more than 5°C to the enclosure
Test duration: 30 min.

Protection class IPX8:

Immersion protection for a defined time and depth
Test by complete immersion
Deepest point of the enclosure *defined depth under the water surface
Water temperature: Difference not more than 5°C to the enclosure
Test duration: *defined time

Protection class IPX9:

Protection against hot high pressure jet water
Testing with high pressure nozzle at an angle of 0°, 30°, 60°, 90°
Distance between enclosure surface and water nozzle: 150 - 200 mm
Enclosure mounted on a rotating table with 5 rpm
Water flow rate: 14 - 16 l/min
Water force: 0,9 - 1,2 N
Water temperature: 75 - 85 °C
Test duration: 30 sec./side

Salt spray test (DIN EN 9227:2012-09)

In our salt spray chamber we use salt spray to create a corrosive atmosphere. Under these conditions, the corrosion process is accelerated in comparison to a normal installation environment. This enables us to detect weak points in the enclosures and accessory components before series production and to take appropriate countermeasures.

Pre-treatment: Cross cut according to DIN EN ISO 2409
Dilution: Sodium Chloride: 50 ± 5 g/l
PH value: 6.5 - 7.2
Water temperature: 35 ± 2 °C
Test duration: 1,000 h
