IP67 vs IP54: Which IP Rating Does Your Inspection Robot Need?
Quick Answer: IP67 provides complete dust-tight protection and withstands water immersion up to 1 meter for 30 minutes. IP54 provides partial dust protection and splash resistance only. For outdoor industrial inspection — including power substations, oil & gas, mining, and chemical plants — IP67 is the minimum recommended rating. IP54 is suitable for indoor or sheltered environments only.
Understanding the IP Code
The IP (Ingress Protection) rating system is defined by IEC 60529 and classifies the degree of protection provided by mechanical casings and electrical enclosures against intrusion of solid objects, dust, accidental contact, and water. The rating consists of two digits: the first indicates solid particle protection, the second indicates liquid ingress protection.

Common Questions About IP Rating FAQ for Inspection Robots
Answers to the most common questions from procurement managers, system integrators, and engineering teams evaluating our robotic platforms.
IP67 means the robot is completely dust-tight (6) and can withstand immersion in water up to 1 meter deep for 30 minutes (7). For inspection robots, this means they can operate in heavy rain, wash-down environments, and areas with standing water — making them suitable for outdoor industrial sites, oil & gas facilities, and water treatment plants.
IP54 provides protection against dust ingress (5 = dust protected, not dust-tight) and water splashing from any direction (4). IP67 provides complete dust-tight protection (6) and full immersion protection up to 1 meter for 30 minutes (7). IP67 is significantly more robust and suitable for harsher environments including outdoor use in rain and wet industrial settings.
For most outdoor industrial inspection applications — including power substations, oil & gas facilities, mining sites, and chemical plants — IP67 is strongly recommended. IP54 may be sufficient for indoor or sheltered environments with limited water exposure. If your site experiences heavy rain, wash-down procedures, or potential flooding, IP67 is the minimum recommended rating.
IP67 is generally sufficient for Zone 2 oil & gas environments from an ingress protection standpoint. However, oil & gas inspection robots also require ATEX or IECEx certification for explosion-proof operation in hazardous areas. IP67 addresses water and dust ingress, while ATEX/IECEx addresses explosive atmosphere safety — both are required for oil & gas deployment.
Chemical plant inspection robots should have a minimum of IP67 to handle chemical splashes, wash-down procedures, and outdoor exposure. For areas with corrosive chemicals, the robot enclosure materials must also be chemically resistant. In ATEX Zone 1 or Zone 2 areas, ATEX certification is required in addition to IP67.
Standard IP67 robots are rated for immersion up to 1 meter for 30 minutes — not for sustained underwater operation. For underwater inspection, you need IP68-rated equipment (continuous immersion beyond 1 meter). IP67 inspection robots are suitable for crossing shallow water obstacles and operating in heavy rain, but not for underwater survey missions.
