IP ratings are international standards that measure a case's dust and water protection. Many products claim IP67, but actual performance varies. How can you tell if the rating is real? This article explains the standard, testing methods, and buying tips.

What IP Codes Mean

An IP code consists of two digits, e.g., IP67. The first digit indicates dust protection (0-6), and the second digit indicates water protection (0-9). First digit 6 means completely dust-tight, no dust ingress. Second digit 7 means can withstand immersion in 1 meter of water for 30 minutes. Therefore, IP67 means the case is completely dustproof and can briefly withstand immersion at a certain depth.

How Real IP67 Testing is Done

Formal IP67 testing is conducted in third-party laboratories. The dust test places the case in a dust chamber, applies negative pressure, and rotates it for 8 hours. The water test immerses the case in 1 meter of water for 30 minutes, then inspects for water ingress. After testing, the laboratory issues a formal report. IP67 claims without a third-party report or with only a manufacturer's self-declaration are less credible.

How to Spot Fake Ratings

  • Check for third-party test reports from SGS, TÜV, CQC, etc.
  • Inspect seal material and installation quality; poor seals rarely achieve IP67
  • Look at case seams and latch design; large or uneven gaps hurt sealing
  • Ask the manufacturer for specific test conditions and report numbers
  • Avoid products priced far below market levels
