The following
IP code ratings for ingress protection (IP), as defined by the
International Electrotechnical Commission (IEC) standard 60529 (equivalent to European standard EN 60529), are typically used for certifying various
toughened and ruggedised smartphones.
Primary standard IP54 — Solid particle (dust) protection level 5 (protection from harmful dust) and liquid ingress (waterproof) protection level 4 (protection from splashing water from any direction).
IP56 — Solid particle (dust) protection level
5 (protection from harmful dust) and liquid ingress (
waterproof) protection level
6 (protection from high pressure water jets).
Intermediate standard IP57 — Solid particle (dust) protection level
5 (protection from harmful dust) and liquid ingress (waterproof) protection level
7 (protection from full immersion at depths between and ).
Testing procedure per ISO 20653 • A spray nozzle that is fed with water at and a flow rate of . • The nozzle is held from the tested device at
angles of 0°, 30°, 60°, and 90°, for 30 seconds each. • The test device places on a
turntable that rotates once every 12 seconds. is a
U.S. military standard that stipulates a level of durability for an item of equipment. Specifically, it means the equipment has been subjected to a series of twenty-nine (29) tests, including
shock tests,
vibration tests, and more. This means it should be field ready, or even '
combat ready' in principle. A lot of technology sold to the U.S. military must be MIL-STD-810G compliant. ==List of rugged smartphones==
