The table below offers a detailed description of the different IP certification levels. The first number relates to solids protection (e.g. dust) whilst the second number relates to liquids protection. For the Beosound A1 2nd Gen with an IP67 rating, this means that it is fully dust-tight and can withstand immersion in water up to 1 meter for up to 30 minutes.

1 |
Ingress: >50 mm / 2.0 in any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part |
Dripping Water: vertically falling drops mounted in an upright position onto a turntable and rotated at 1 RPM for 10 minutes |
|
2 |
Ingress: >50 mm / 2.0 in any large surface of the body, such as the back of a hand, but no protection against deliberate contact with a body part |
Dripping water when tilted at 15° - four positions tested within two axes for 2.5 minutes each – a total of 10 minutes |
|
3 |
Ingress: >2.5 mm / 0.098 in tools, thick wires, etc. |
Spraying Water: Water falling as a spray at any angle up to 60° from the vertical for either 10 minutes with an oscillating fixture or 5 minutes with the shield |
|
4 |
Ingress: >1 mm / 0.039 in most wires, slender screws etc. |
Splashing Water: Water splashing against the enclosure from any direction for either 10 minutes with an oscillating fixture or 5 minutes without a shield |
|
5 |
Dust 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. |
Water Jets - Water projected by a nozzle (6.3 mm (0.25 in)) against the enclosure from any direction for at least 3 minutes. |
|
6 |
Dust Tight: No ingress of dust; complete protection against contact (dust-tight). A vacuum must be applied with a test duration of up to 8 hours based on airflow. |
Powerful Water Jets - Water is projected in powerful jets (12.5 mm (0.49 in)) against the enclosure from any direction for at least 3 minutes. |
