In a previous blog post we discussed IP ratings and the many different classifications that exist for protection of an object against particles and water. These IP ratings are common across many products – just apply the methodology of testing to each product in question. Now let’s take a closer look at the classifications that fall under the waterproof category. Just like the new Samsung phone that is IP67 rated (waterproof), we use the actual IP rating to describe how much water a light can withstand. The table below outlines the three important IP ratings for water and what type of testing is endured.
|IP Rating||Protection||Description||Test Method|
|IP65 Enclosures||Able to protect against water jets||Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects.||Test duration: at least 15 minutes|
|Water volume: 12.5 litres per minute|
|Pressure: 30 kPa at distance of 3 m|
|IP66 Enclosures||Able to protect against powerful water jets||Water projected in powerful jets (12.5 mm nozzle) against the enclosure from any direction shall have no harmful effects.||Test duration: at least 3 minutes|
|Water volume: 100 litres per minute|
|Pressure: 100 kPa at distance of 3 m|
|IP67 Enclsoures||Able to protect against Immersion up to 1 m||Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).||Test duration: 30 minutes|
|Immersion at depth of at least 1 m measured at bottom of device, and at least 15 cm measured at top of device|
It is important to understand what type of IP rating is necessary for your application if you have a facility where the lights may come in contact with water. One of the many benefits of our Sigma ICE series of LED light fixtures is that all come with a minimum of an IP66 rating, many with an IP67 rating. This level of rating ensures that your lights will be protected in any situation. Many of us are experiencing significant amounts of rain – imagine you walk into work tomorrow and find that the roof has been leaking all night. You will have one less headache knowing that the Sigma ICE LED products installed will not be damaged even if there is a steady stream of water pouring over them! If you have any questions about IP ratings or what fixture works best for your unique application the team at Sigma Luminous can help.
