IP Rating Help
IP55 time duration
How much time can equipment with ip 55 should stand rain water without problem?
There is a minimum time of at least 15 minutes, which is used for testing purposes, but we would suggest a product should be designed and tested for the intended purpose rather than a particular IP rating. You can then have a third party test the design to see what IP rating it meets.
IP Testing
Which consultant can carry out IP rating testing?
We would suggest contacting SIRA which are major provider of instrumentation certification and approval services in the UK including IP testing.
IPW55 vs IP55
What is the difference between IP55 and IPW55 protection?
The “W” in IPW 55 signifies that the rating includes weather conditions. e.g. rain, condensation and humidity.
IP55
- Limited dust ingress protection.
- Protected against low pressure water jets from any direction.
IPW55
- Limited dust ingress protection.
- Protected against low pressure water jets from any direction.
- Protected against damp and wet weather.
Condensation protection (IP21)
What is meant by protected against condensation as part of a IP21 rating?
When the surface temperature of a device is lower than the dew point temperature (the temperature at which air cannot hold any more water) moisture will begin to collect on the device.
For example, condensation will form if you take a device that has been sitting in a cool environment such as an air conditioned room and move it to a hot and humid outdoor environment.
If a device has an IP21 rating it will be protected from damage due to any build up of moisture on surfaces which are in contact with the air.
Sensitive components such as electronic devices are protected from condensation by coating the surface with a waterproof barrier such as a Conformal coating.
IP23S vs IP23
What is the difference between IP23 and IP23S, and which has a more stringent testing criteria?
The ‘S’ means ‘Device standing still during water test’. IP23 is considered more stringent than IP23S, since it covers this and IP23M which means ‘Device moving during water test’.
D meaning in IP23D
I have a heat detector for a fire alarm system and I have been told it is ip23d, can you please let me know what the ‘d’ is?
It is additional to the IP23 rating, and relates to protection against a wire touching hazardous parts. For futher information see IP codes explained and additional IP code letters.
B meaning e.g. IP43B
What is the meaning of the ‘B’ in IP41B ?
The “B” means: Protected against access to hazardous parts with a finger.
