The subsequent sections will delve into specific models, associated Ingress Protection (IP) ratings, the technology used to achieve water resistance, and considerations for selecting a suitable device based on intended use.
1. IP Rating
Ingress Protection (IP) ratings are crucial indicators of a water resistant Android tablet’s ability to withstand environmental hazards. These ratings provide a standardized method for classifying the degree of protection an enclosure offers against the intrusion of solid objects (dust) and liquids (water). Understanding these ratings is essential for selecting a tablet suitable for specific usage scenarios.
-
First Digit: Solid Particle Protection
The first digit in the IP rating (e.g., IP67) denotes the level of protection against solid objects, ranging from tools and large objects to dust. A rating of ‘6’ signifies complete protection against dust ingress, meaning no dust can penetrate the device and interfere with its operation. This is particularly important in environments prone to dust exposure, such as construction sites or outdoor settings.
-
Second Digit: Liquid Ingress Protection
The second digit indicates the level of protection against water ingress. Values range from ‘0’ (no protection) to ‘9K’ (protection against powerful high-temperature water jets). A common rating for water resistant Android tablets is IP67 or IP68. IP67 means the device can withstand immersion in up to 1 meter of fresh water for 30 minutes. IP68 offers protection against immersion beyond 1 meter, with the exact depth specified by the manufacturer.
-
Testing Protocols and Standards
IP ratings are determined through rigorous testing following international standards, such as IEC 60529. These tests involve exposing the device to specified amounts of dust and water under controlled conditions. The tablet must continue functioning normally after the tests to achieve a particular IP rating. The reliability of an IP rating is contingent on adherence to these standardized testing procedures.
-
Limitations and Considerations
While IP ratings provide a useful benchmark, they are not a guarantee of complete impermeability. The protection applies to fresh water only and may not extend to saltwater, chlorinated water, or other liquids. Furthermore, the protection can degrade over time due to wear and tear, physical damage, or improper maintenance. Immersion beyond the specified depth or duration can compromise the device’s water resistance, even if it initially holds a high IP rating.
In conclusion, IP ratings provide a standardized measure of a water resistant Android tablet’s ability to withstand dust and water ingress.
