IP68 vs IP62
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP68 and IP62 are both IEC 60529 ingress protection codes, but they differ in liquid protection (level 8 vs 2). IP68 is rated for dust-tight and continuous immersion (manufacturer-specified), while IP62 provides dust-tight and dripping water at 15° tilt.
IP68 is dust-tight and protects against continuous immersion in water under conditions specified by the manufacturer (typically deeper than 1 meter for prolonged periods). The standard for submersible and marine equipment.
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 (IP68 vs IP62)
Solid protection
IP68
Level 6 — Dust-Tight
IP62
Level 6 — Dust-Tight
Both IP68 and IP62 share the same solid protection: Dust-Tight.
Liquid protection
IP68
Level 8 — Continuous Immersion (manufacturer-specified)
IP62
Level 2 — Dripping Water at 15° Tilt
IP68 handles Specified by manufacturer (Continuous Immersion (manufacturer-specified)), while IP62 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP68 provides 6 levels more liquid protection.
NEMA equivalents
No direct NEMA equivalent.
Recommendation
IP68 offers higher overall protection than IP62. Choose IP68 for harsher environments; IP62 may suffice for milder conditions and can be more cost-effective.
