Nemko has a large laboratory for testing various types of water ingress. This can include condensation via dripping, spraying, splashing and hosing to submerging in water tanks. It can also include dust ingress in dust circulation chambers and ingress tests with different foreign objects and different standardized access probes.
We can perform fully automated and accredited tests for the whole range of IP classifications according to IEC 60529 and NEMA 250.
We provide testing according to:
Relevant test in the IEC 60068-series
Relevant test in the IEC 60721-series
Relevant test in the ETS 300 019 environmental standards and classification of parameters for equipment functionality in different environments.
Note: Some countries like Russia requires hygienic testing before export is allowed. Nemko has long experience in helping manufacturers with documenting such requirements for exporting of their products.

What are IP codes?
EN 60529 outlines an international classification system for the sealing effectiveness of enclosures for electrical equipment against the intrusion into the equipment from foreign objects (i.e. hands, fingers, tools, dust) and water. This classification system utilizes the letters “IP” (“Ingress Protection”) followed by two or three digits.
A third character is sometimes used to further specify the classification
An "x" is used to replace one of the digits if there is only one class of protection; i.e. IPX4 which addresses water resistance only
