IP67 RT8

What does the IP67 that on radio ads title means ?

What does the IP67 that on RT6 and RT8 ads title means ? May many customers are confused of what IP67 is .So let’s talk about it this time.

IP stands for ‘Ingress Protection’ . An IP number is used to specify the environmental protection of enclosures around electronic equipment. These ratings are determined by specific tests.

The IP number is composed of two numbers. the first referring to the protection against solid objects and the second against liquids. The higher the number, the better the protection.

For example :

Ingress ProtectionSolids ProtectionLiquids Protection


First Digit: Solids

The first digit indicates the level of protection that the enclosure provides against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid foreign objects.

IP LevelObject size protected against                                              Effective against
0Not protectedNo protection against contact and ingress of objects
1>50mmAny large surface of the body, such as the back of the hand, but no protection against deliberate contact with a body part.
2>12.5mmFingers or similar objects.
3>2.5mmTools, thick wires, etc.
4>1mmMost wires, screws, etc.
5Dust Protected Ingress of dust is not entirely prevented, but it must not enter in sufficient quantity to interfere with the satisfactory operation of the equipment; complete protection against contact.
6Dust Tight No ingress of dust; complete protection against contact.

Second Digit: Liquids

Protection of the equipment inside the enclosure against harmful ingress of water.

IP LevelObject size protected against                                             Effective against
0Not protected
1Dripping waterDripping water (vertically falling drops) shall have no harmfull effect.
2Dripping water when tilted up to 15°Vertically dripping water shall have no harmful effect when the enclosure is tilted at an angle up to 15° from its normal position.
3Spraying waterWater falling as a spray at any angle up to 60° from the vertical shall have no harmful effect.
4Splashing waterWater splashing against the enclosure from any direction shall have no harmful effect.
5Water jetsWater projected by a nozzle (6.3mm) against enclosure from any direction shall have no harmful effects.
6Powerful water jets Water projected in powerful jets (12.5mm nozzle) against the enclosure from any direction shall have no harmful effects.
7Immersion up to 1mIngress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
8Immersion beyond 1mThe equipment is suitable for continuous immersion in water under conditions which shall be specified by the manufacturer. Normally, this will mean that the equipment is hermetically sealed. However, with certain types of equipment, it can mean that water can enter but only in such a manner that it produces no harmful effects.

And Both RT6 & RT8 are the IP67 Waterproof, Dustproof, Resistance radios . As the pictures below —

    Hi Zoe: a quick further question regarding waterproofing. Does having an earpiece or or external mic compromise the water proofing? I envisage using the radio on boats where it is unlikely to be fully immersed but will be exposed to rain, spray and splashing.
