IP07 vs IP31
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP07 and IP31 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 0 vs 3) and liquid protection (level 7 vs 1). IP07 is rated for no protection and temporary immersion (up to 1 m), while IP31 provides > 2.5 mm — tool / wire and vertically dripping water.
IP07 is an ingress protection code that ensures no protection against solid objects and protection against the effects of temporary immersion in water. Ingress of water in quantities causing harmful effects shall not be possible.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 0 with second-digit (liquid) level 7.
The IP31 rating offers protection against solid objects larger than 2.5 mm and protection against vertically falling drops of water. Dripping water shall have no harmful effects.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 3 with second-digit (liquid) level 1.

The exact difference (IP07 vs IP31)
Solid protection
IP07
Level 0 — No Protection
IP31
Level 3 — > 2.5 mm — Tool / Wire
IP07 provides "No Protection" (level 0), while IP31 provides "> 2.5 mm — Tool / Wire" (level 3). IP31 is 3 levels higher.
Liquid protection
IP07
Level 7 — Temporary Immersion (up to 1 m)
IP31
Level 1 — Vertically Dripping Water
IP07 handles Hydrostatic ~10 kPa at 1 m (Temporary Immersion (up to 1 m)), while IP31 handles 0.1 mm/min drip rate (Vertically Dripping Water). IP07 provides 6 levels more liquid protection.

Recommendation
IP07 offers higher overall protection than IP31. Choose IP07 for harsher environments; IP31 may suffice for milder conditions and can be more cost-effective.
