Quick Answer
- IP rating first digit indicates dust protection level (0-6), second digit shows water resistance (0-9)
- IP67 offers full dust protection and 30 minutes submersion at 1 meter depth
- IP68 provides complete dust protection and continuous immersion beyond 1 meter depth
- Higher numbers always indicate better protection, with IP6X being dust-tight
- Testing involves standardized procedures by IEC for certification compliance
Understanding IP Rating Scale: Breaking Down the Numbers System
• IP rating uses a two-digit system where first digit measures solid particle protection (0-6) and second digit measures liquid protection (0-9) • First digit range: 0=no protection to 6=complete dust tight protection against all solid objects • Second digit range: 0=no protection to 9=protection against high-pressure water jets and steam cleaning • Common ratings: IP67 allows temporary submersion up to 1 meter for 30 minutes while IP68 offers continuous underwater protection at greater depths
- What Does IP Rating Mean for Electronics
The ingress protection code system provides standardized testing results that manufacturers must verify through third-party certification. The first number indicates resistance to dust, dirt, and solid objects entering the device housing. The second number shows liquid resistance capabilities including dripping water, spray, immersion, or high-pressure jets.
- How to Read IP67 vs IP68 Rating Differences
IP67 devices achieve complete dust protection (6) and can survive temporary submersion in water up to 1 meter deep for 30 minutes (7). IP68 ratings provide identical dust protection but offer superior liquid resistance for continuous underwater use at depths exceeding 1 meter, with specific conditions defined by manufacturers.
- IP Rating Chart Explained Simply
Protection levels escalate significantly between ratings. IP54 offers limited dust protection and splashing water resistance, while IP65 blocks all dust and withstands low-pressure water jets. Higher ratings like IP68 require rigorous testing including temperature cycling, vibration, and extended water exposure periods.
- Choose IP67 if you need reliable outdoor protection against dust and occasional water exposure. Choose IP68 if your application requires permanent submersion or extreme liquid exposure conditions.
