IP05 vs IP15
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP05 and IP15 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 1). IP05 is rated for no protection and water jets (6.3 mm nozzle), while IP15 provides > 50 mm — back of hand and water jets (6.3 mm nozzle).
Under IEC 60529, IP05 specifies no protection against solid objects and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 5.
With IP15, an enclosure receives protection against solid objects larger than 50 mm and protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 5.

The exact difference (IP05 vs IP15)
Solid protection
IP05
Level 0 — No Protection
IP15
Level 1 — > 50 mm — Back of Hand
IP05 provides "No Protection" (level 0), while IP15 provides "> 50 mm — Back of Hand" (level 1). IP15 is 1 level higher.
Liquid protection
IP05
Level 5 — Water Jets (6.3 mm nozzle)
IP15
Level 5 — Water Jets (6.3 mm nozzle)
Both IP05 and IP15 share the same liquid protection: Water Jets (6.3 mm nozzle).

Recommendation
IP15 offers higher overall protection than IP05. Choose IP15 for harsher environments; IP05 may suffice for milder conditions and can be more cost-effective.
