IP15
Last updated: Aug 9, 2026With 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.

What IP15 means
The IP code IP15 is part of the IEC 60529 standard for ingress protection. The first characteristic numeral, 1, indicates the level of protection against solid objects and access to hazardous parts. The second numeral, 5, indicates the level of protection against the ingress of water. Together, these digits describe exactly what an enclosure rated IP15 can withstand.
For solid protection, the digit 1 means the enclosure is > 50 mm — back of hand. Protected against access to hazardous parts with the back of a hand. Protected against solid foreign objects of 50 mm diameter and greater. The test method is access probe (50 mm sphere) shall not fully penetrate and shall have adequate clearance from hazardous parts.
For liquid protection, the digit 5 means the enclosure resists water jets (6.3 mm nozzle). Protection against water jets. Water projected by a 6.3 mm nozzle against the enclosure from any direction shall have no harmful effects. The test procedure is standard nozzle (6.3 mm diameter) at 30 kpa, 12.5 l/min; water aimed at enclosure from all practicable directions.
IP15 vs IP16: the higher rating adds powerful water jets. When specifying IP15 for a project, confirm the rating certificate from the manufacturer and consider that seals degrade over time with temperature cycling, UV exposure, and chemical contact.
