IP protection classes for tablets and smartphones
How well are tablets protected against water or dirt?
Looking for a Rugged Tablet or Rugged Handheld and wondering how much protection they offer? IP protection classes provide the answers. We explain what to look for: What does IP65 mean? What is an IP67 certification? The following table provides an immediate overview how well tablets are protected against water and dirt.
Originally, IP protection classes (IP codes) were not used for tablets or computers. They apply to other types of electronic devices, like lighting. The idea was that users could see at one glance whether a device is suitable for use at a construction site or in a factory environment, where damage form rain, moisture, sand or dust is a constant threat.
The higher the number, the better the protection
The IP code according to DIN EN 60529 consists of two digits. The higher the number, the better the protection. The first digit (for example the 5 for IP54) stands for protection against hazardous particals (sand, dirt, dust) and contact. The scale runs from 0 to 6. The second digit (in our example the 4) explains the protection against water. This scale ranges from 0 to 9. For Rugged Tablets, Rugged Smartphones and Rugged PCs, three protection classes are particularly relevant: IP54, IP65 and IP67.
|IP Schutzart||1st code digit||2nd code digit|
|IP54||5: protected against damaging amounts of dust and complete protection against contact||4: protection against water splashing from all directions||IP54-rated Rugged Tablets are protected against hazardous amounts of dust but not completely dust-proof, and they withstand humidity and light rain.|
|IP65||dust tight and complete protection against contact||5: protection against water jets from any direction||Rugged tablets with IP65 protection are dust tight and withstand high levels of humidity and heavy rain and are thus suitable for shipping.|
|IP67||6: dust tight and complete protection against contact||7: protection against temporary immersion in water||Rugged tablets with IP67 protection are completely dust tight and are suitable for employment in conditions where they can fall into water or are temporarily exposed to flooding.|
IP protection determines the suitability of tablets for employment in manufacturing, food processing, fire departments, police, disposal or maintenance. Other important features for Rugged tablets, such as temperature range, humidity range, shock and vibration protection, are not covered by IP protection classes, but commonly expressed by MIL-STD standard.
