Sand/ Dust/ Rain/ Water Immersion Test
 

Products installed beneath eaves (e.g. surveillance cameras), portable outdoor/semi-outdoor products, and automobile electronics are all required to be tested. International organizations such as IEC, MIL or ETSI and SAE have published corresponding test specifications. IEC/EN 60529 (IP Code) is the most frequently used regulation for consumer products, where protection classes and test procedures and methods are specified according to intended usage of products. Nowadays this standard is gaining a popularity globally.

There are 7 classes (0-6) of protection against dust permeation; 9 classes (0-8) of protection against water permeation, they are normally indicated as IPXX and widely employed globally, where IP stands for International Protection or rather Ingression Protection, to be more accurate, the first X stands for particle protection and the second X stands for water protection. Therefore, a product indicating IP54 will mean a particle protection of Class 5 (dust) and a water protection of Class 4.

Protection against dust ingression (e.g. IP5X- Class 5 dust protection)
   Level 0: no particle protection at all.
   Level 1: protection against ingression of particle of diameter > 50mm (the spherical tester of 50mm diameter shall not fall into enclosure entirely).
   Level 2: protection against ingression of particle of diameter >12mm (the spherical tester of 12.5mm diameter shall not fall into enclosure entirely).
   Level 3: protection against ingression of particle of diameter > 2.5mm (the spherical tester of 2.5mm diameter shall not fall into enclosure entirely).
   Level 4: protection against ingression of particle of diameter > 1mm (the spherical tester of 1mm diameter shall not fall into enclosure entirely).
  Level 5: partially dust proof (partially dust proof, but dust ingression shall not affect normal operation of theproduct or degrade product safety).
   Level 6: totally dust tight (no dust ingression into enclosure).

Protection against Water ingression (e.g. IPX4- class 4 splash proof)
   Level 0: no water protection at all.
   Level 1: protection against vertical dripping water (no damage caused due to vertical dripping water into enclosure).
   Level 2: protection against dripping water in an angle of 15 degrees in respect to the product (no damage caused due to water dripping into enclosure in an angle of 15 degrees in respect to the product).
   Level 3: protection against spraying water in an angle of 60 degrees (no effect to normal operation or safety of product due to water spray).
   Level 4: protection against spraying water in an angle of 180 degrees (no effect to normal operation or safety of product due to water splash).
   Level 5: protection against water jet (no effect to normal operation or safety of product due to water jet in any direction aiming at the enclosure).
   Level 6: protection against severe flooding (no effect to normal operation or safety of product due to water flooding in any direction to the enclosure).
   Level 7: protection against water immersion (no effect to normal operation or safety of product due to immersion in water for a specified period of time).
   Level 8: protection against continued immersion in water (no effect to normal operation or safety of product due to immersion in water in accordance with period of time (no less than that in level 7) specified by the manufacturer).
