It is reported that up to 20% of all phone damage occurs as a result of immersion or contact with a liquid. That is why manufacturers claim their devices are waterproof, but what do the IP ratings they advertise actually mean?
The ratings are beneficial to both manufacturers and consumers. They are based on International Standards that enable manufacturers to offer a level of protection that is clearly defined and tested. For consumers, this protection provides a verifiable assurance.
IP 67 vs. IP 68
Two of the current, top-of the-range flagship phones are rated as splash, water, and dust resistant to IP67 and IP 68 respectively. The first digit following the IP shows the phone’s resistance to dust and the second to water.
They both get sixes, which is the top score, indicating no ingress of dust.
When it comes to water resistance, the scale runs from zero (no protection) to nine (high-pressure hot water from different angles). Both the flagship phones are water resistant, but there is a significant difference between achieving a seven or an eight rating.
Standards and conformity assessment
The IEC provides International Standards and conformity assessment for all electrical, electronic and related technologies. IEC conformity assessment verifies that Standards are properly applied in real-world technical systems to guarantee safety and quality, in this way adding value to products and services.
This may mean using different kinds of conformity assessment—ranging from corporate self-assessment to relying on supplier’s declarations to independent, third-party assessment and testing—whichever are most appropriate according to the different levels of risk.
