IP 69K Test Laboratory

Introduction to IP Testing:

1. Purpose of IP Testing: Verify the protective function of product enclosures.

   - Prevent human contact with dangerous internal components.

   - Prevent solid foreign objects from entering the enclosure.

   - Prevent harmful effects caused by water ingress into the enclosure.

2. Meaning of IP Protection Ratings: "International Protection," such as IP67.

   - The first numeral (e.g., 6) indicates the dust protection level.

   - The second numeral (e.g., 7) indicates the water protection level.

3. Dust Protection Levels and Requirements:

   - IP0X: No protection; no requirements.

   - IP1X: Protection against large objects (back of hand); 50 mm diameter probe must maintain sufficient distance from hazardous parts.

   - IP2X: Protection against medium objects (finger); 12.5 mm diameter, 80 mm long articulated probe must maintain sufficient clearance from hazardous parts.

   - IP3X: Protection against tools; 2.5 mm diameter probe must not penetrate the enclosure.

   - IP4X: Protection against wires; 1 mm diameter probe must not penetrate the enclosure.

   - IP5X: Dust protected; dust must not interfere with normal operation and safety.

   - IP6X: Dust tight; no dust ingress.

4. Water Protection Levels and Requirements:

   - IPX0: No protection; no requirements.

   - IPX1: Protection against vertical water drops; no harmful effects from vertical dripping water.

     - Water flow: 1 mm/min

     - Turntable speed: 1 rpm

     - Test duration: 10 min

   - IPX2: Protection against water drops when tilted at 15°; no harmful effects with enclosure tilted 15°.

     - Water flow: 3 mm/min

     - Test angle: 15° to vertical

     - Duration: 2.5 min per surface

   - IPX3: Protection against spraying water; no harmful effects from spraying water at 60° angle.

     - Water flow: 0.07 L/min per nozzle

     - Distance: 200 mm

     - Test duration: 10 min

   - IPX4: Protection against splashing water; no harmful effects from splashing water.

     - Same flow and test conditions as IPX3, with 360° arc coverage.

   - IPX5: Protection against water jets; no harmful effects from water jets.

     - Flow: 12.5±0.625 L/min

     - Nozzle diameter: 6.3 mm

     - Distance: 2.5–3 m

     - Test duration: 3 min

   - IPX6: Protection against powerful water jets; no harmful effects from powerful water jets.

     - Flow: 100±5 L/min

     - Nozzle diameter: 12.5 mm

     - Same conditions as IPX5

   - IPX7: Protection against immersion; no harmful effects from immersion at 1 m depth for 30 min.

     - Enclosure point below water surface: 1000 mm minimum.

   - IPX8: Protection against prolonged immersion; custom-defined depth and duration exceeding IPX7.

     - Conditions set by manufacturer.

   - IPX9: Protection against high-temperature/high-pressure water jets.

     - Angles: 0°, 30°, 60°, 90°

     - Temperature: 80°C

     - Distance: 175±25 mm

     - Flow: 15±1 L/min

     - Test duration: 30 s per angle
