High level of enclosure protection with IP 65 testing

Electrical and electronic devices that are used outdoors or in the open need to be able to withstand harsh weather and environmental influences.

The tests for protection class IP 65 check that the products cannot be damaged by water, foreign objects or contact. The IP code classification consists of the digits 6 and 5. The first digit indicates the degree of protection against the ingress of foreign objects as well as contact with the enclosure, while the second digit indicates the degree of protection against the ingress of water.

No ingress of dust or water

To test whether a device or an enclosure is dust-tight and protected against the ingress of foreign objects, it is placed in a chamber in the laboratory and treated with a high concentration of dust. The standard is met if no dust ingresses the enclosure. The second test rates the protection against water jets. Here, the product is sprayed with water from all directions by a nozzle in a chamber at a specific pressure. If the device or enclosure is not affected by either dust or water, it is sufficiently protected and is certified as IP-compliant.

Use in harsh environments and outdoors

Devices and components (for example lamps, luminaires or electrical and electronic devices) that meet the IP 65 standard are particularly suitable for use in harsh environments and in industrial plants and sites.

IP 65: Protection against access with wire, dust-tight

Different types of test dust can be used, for example talcum, Arizona dust or a mixture of Portland cement and fly ash.
