Waterproof test chamber is suitable for external lighting and signal device and car lamp shell protection, can provide a realistic simulation of electronic products and components during transportation and using may be subjected to spray water and spray test and other environments.

It is often confusing for an engineer to know what type of rating they need to look for when they desire to have a “waterproof” enclosure.  Much like with watches or other sensitive information, there is a big difference between waterproof, water resistant, and other descriptive but not specific labels.  To help out, there are several rating systems that have been developed although and several testing agencies that verify the results. Among these, the two best known are NEMA and IP. 

For enclosures, the typical “waterproof” IP ratings are IP67, IP66 and IP65 enclosures.  The chart below gives the specifics of what these ratings mean and how they are measured.
