The determination of protection indices, as provided by electrical installation envelopes, yields an evaluation of the access to hazardous zones, the penetration of foreign solid bodies and water penetration (code: IP), as well as the degree of product protection against mechanical shocks (code: IK).
Proposed services
The LNE Laboratory has at its disposal a full set of resources capable of determining all of the following existing indices :
- Characterizations, covering an IP index of 0X to 6X for the penetration of solid bodies,
- Characterizations extending from X0 to X8 for water penetration,
- Determination of the impact energy capable of being withstood by a product envelope, from IK 00 to IK 10.
Resources available
Among our various resources, let's point out :
- for the IP index :
- drop box (rainfall),
- water projection using a nozzle and a hoop,
- pulsed projection using a nozzle,
- immersion basin,
- talc chamber,
- test gauge (sphere, test fingers, testing rods).
- for the IK index :
- spring-loaded shock hammers,
- tilting shock hammers.
Applicable regulations
The proposed set of tests are capable of satisfying many standards, notably :
- NF EN 60529 (IP),
- NF EN 62262 (IK),
- Low Voltage Directive,
- Medical Directive.
Products covered
All electrical, electronic and protection envelope products.
