What IP67 Means
IP67 goes beyond jet-spray protection (IP66) to include protection against temporary submersion in water — typically defined as immersion up to one meter in depth for up to 30 minutes under standard testing conditions, though exact parameters can vary by testing standard. Like IP66, the first digit (6) confirms the fixture is fully dust-tight.
This additional submersion protection matters for fixtures installed in locations where standing water, temporary flooding, or below-grade installation is a realistic possibility — conditions beyond what jet-spray resistance alone would cover.
IP67 vs. IP66
The distinction is specifically about water exposure type:
- IP67 adds protection against temporary submersion, beyond jet-spray resistance.
- IP66 protects against powerful directed water jets but not submersion.
Both offer identical dust protection (fully dust-tight); the difference is purely in the water protection scenario each is tested against.
Where IP67 Is Needed
- Facilities prone to flooding or standing water — areas where water accumulation is a realistic operating condition
- Marine-adjacent and coastal industrial sites — locations with elevated moisture and flooding risk
- Below-grade or low-mounted outdoor installations — fixtures positioned where water pooling is more likely
Choosing the Right Rating
Evaluate whether your installation location has realistic exposure to standing water or temporary flooding, not just rain or spray. If so, IP67 provides meaningfully more protection than IP66 for that specific risk. For locations without submersion risk, IP66 is often sufficient and may be more cost-effective.
