IP10 vs IP31
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP10 and IP31 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 3) and liquid protection (level 0 vs 1). IP10 is rated for > 50 mm — back of hand and no protection, while IP31 provides > 2.5 mm — tool / wire and vertically dripping water.
IP10 provides protection against solid objects larger than 50 mm and no protection against water. It is an IEC 60529 ingress protection code combining first-digit (solid) level 1 with second-digit (liquid) level 0.
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.

Recommendation
IP31 offers higher overall protection than IP10. Choose IP31 for harsher environments; IP10 may suffice for milder conditions and can be more cost-effective.
