IEC 60529 — Ingress Protection (IP) Rating System

Overview

IEC 60529 defines the IP (Ingress Protection) code for classifying degrees of protection provided by enclosures of electrical equipment against solid foreign objects (including dust) and water. It helps manufacturers, designers, and users understand how well a device's enclosure prevents intrusion that could cause harm or reduce functionality.

First Digit — Solid Object Protection (0–6)

• 0: No protection.
• 1: Protected against solid objects >50 mm (e.g., large surface of the body).
• 2: >12.5 mm (fingers).
• 3: >2.5 mm (tools, thick wires).
• 4: >1.0 mm (most wires, screws).
• 5: Dust protected — ingress of dust is not entirely prevented but does not interfere with operation; limited ingress permitted.
• 6: Dust tight — no ingress of dust; complete protection.
