IP14 vs IP42
Head-to-head comparison of two IEC 60529 ingress protection ratings.
IP14 and IP42 are both IEC 60529 ingress protection codes, but they differ in solid-object protection (level 1 vs 4) and liquid protection (level 4 vs 2). IP14 is rated for > 50 mm — back of hand and splashing water (all directions), while IP42 provides > 1 mm — small wires and dripping water at 15° tilt.
Under IEC 60529, IP14 specifies protection against solid objects larger than 50 mm and protection against splashing water. Water splashed 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 4.
With IP42, an enclosure receives protection against solid objects larger than 1.0 mm and protection against vertically falling drops of water when the enclosure is tilted up to 15° from its normal position.. It is an IEC 60529 ingress protection code combining first-digit (solid) level 4 with second-digit (liquid) level 2.

The exact difference (IP14 vs IP42)
Solid protection
IP14
Level 1 — > 50 mm — Back of Hand
IP42
Level 4 — > 1 mm — Small Wires
IP14 provides "> 50 mm — Back of Hand" (level 1), while IP42 provides "> 1 mm — Small Wires" (level 4). IP42 is 3 levels higher.
Liquid protection
IP14
Level 4 — Splashing Water (all directions)
IP42
Level 2 — Dripping Water at 15° Tilt
IP14 handles 50–100 kPa (Splashing Water (all directions)), while IP42 handles 0.3 mm/min drip rate (Dripping Water at 15° Tilt). IP14 provides 2 levels more liquid protection.

Recommendation
IP42 offers higher overall protection than IP14. Choose IP42 for harsher environments; IP14 may suffice for milder conditions and can be more cost-effective.
