IP18 vs IP62
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP18 and IP62 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 6) and liquid protection (level 8 vs 2). IP18 is rated for > 50 mm — back of hand and continuous immersion (manufacturer-specified), while IP62 provides dust-tight and dripping water at 15° tilt.
The IP18 classification guarantees protection against solid objects larger than 50 mm and protection against the effects of continuous immersion in water under conditions specified by the manufacturer.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 8.
Built to withstand dust-tight (no ingress of dust) and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. Classified as IEC 60529 ingress protection code IP62, it pairs solid level 6 with liquid level 2.

The exact difference (IP18 vs IP62)
Solid protection
IP18
Level 1 — > 50 mm — Back of Hand
IP62
Level 6 — Dust-Tight
IP18 provides "> 50 mm — Back of Hand" (level 1), while IP62 provides "Dust-Tight" (level 6). IP62 is 5 levels higher.
Liquid protection
IP18
Level 8 — Continuous Immersion (manufacturer-specified)
IP62
Level 2 — Dripping Water at 15° Tilt
IP18 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP62 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP18 provides 6 levels more liquid protection.

Recommendation
IP18 offers higher overall protection than IP62. Choose IP18 for harsher environments; IP62 may suffice for milder conditions and can be more cost-effective.
