IP Protection class
The IP protection type code describes the protection of a casing or enclosure against the invasion of solid foreign bodies, against the contact with dangerous parts and against the intrusion of water. The different types of influences are divided into individual IP classes.
The maximum durability, the resilience, and the eligible application field of products are thus made comparable for the user. In addition to water, dust counts as a foreign object.
Because of powerful convection blower, high dust constants can be reached, which in turn, ensures accurate test results.
To develop reliable products, it is important to have precise knowledge of the load profiles occurring in later use. With load measurements on location and with real use, relevant environmental and operating loads are measured and analyzed.
The measurement results serve, on the one hand, as a data basis for testing in the laboratory. On the other hand, the reliability of field loads can be evaluated with already-tested products.
