IP Rating

Ingress Protection (IP) ratings are used to grade resistance of an enclosure against intrusion of dust and water. Introduced in 1976, IEC 60529 is the international standard that defines the IP certification process. ISO 20653 expands on the IEC standard by introducing additional levels of protection.

IP Rating Format
Each IP rating uses the same basic format, starting with the letters IP (Ingress Protection) followed by two numerals. Sometimes, a third letter may follow the numerals to describe additional testing conditions or substances. The first numeral rates dust ingress protection, and the second numeral rates water ingress protection. When an 'X' is displayed instead of a numeral, this indicates no testing or certification for that category.

Garmin Water Rating Definitions

IPX6: Protection against water projected at all angles through a 12.5mm nozzle at 100 liters/min + 100 kN/m2 pressure from 3 meters distance for 3 minutes.

IPX7: Withstands incidental exposure to water of up to 1 meter for up to 30 minutes.

1 ATM: Withstands pressures equivalent to a depth of 10 meters.

3 ATM: Withstands pressures equivalent to a depth of 30 meters.

5 ATM: Withstands pressures equivalent to a depth of 50 meters.

10 ATM: Withstands pressures equivalent to a depth of 100 meters.

Dive: Designed to comply with DIN EN 13319.

Waterproof: Similar to Dive, this rating is used primarily for VIRB action cameras.
