Any purchasers of the new iPhone 15 would have observed that the phone can work up to a maximum depth of six meters for up to 30 minutes since it is rated IP68. What does that even mean? Ingress Protection (IP) ratings, provide valuable information about the protection level of an electrical enclosure against the intrusion of solid objects and liquids. The IP rating system established by the International Electrotechnical Commission (IEC) provides a clear indication of industrial equipment’s ability to withstand environmental factors, particularly water and dust. This blog will look to cover more detail around IP ratings in the context of the manufacturing industry.

Overview of IP Ratings

IP ratings are composed of two digits, each establishing a specific level of protection. The first refers to the protection against solid objects, while the second indicates the protection against liquids. Devices with higher IP ratings, like IP65 or IP66, offer better protection against dust, rain, and even corrosive substances, safeguarding mining plant and equipment and ensuring uninterrupted functionality. However, higher IP ratings do not necessarily mean better protection. For example, an IP rating of 68 provides protection against dust and continuous immersion in water for equipment like throw-in transmitters, but it might not be suitable for areas with high humidity levels because it may not protect against condensation.

The degree of protection against solid contaminants is indicated with a number from 0 to 6. A higher number indicates a higher level of protection against finer contaminants. In the case of the liquids, the degree of protection against ingress is indicated with a number from zero to nine. However, for liquids, higher numbers do not necessarily indicate the component’s ability to withstand a larger amount of water.

Determining IP Ratings for Manufacturing

If a manufacturer is unsure about what IP rating his equipment requires, an expert system integrator provide assistance and recommend the most suitable solution tailored to the manufacturer’s business needs. Many industrial sectors require components with IP ratings, including marine, food processing, pharmaceutical manufacturing, and the agricultural sector. In fact, almost all industrial settings will experience some risk of ingress — particularly if the environment in which it operates is outdoors or in an environment subject to water, heat, or dust. In these cases, their electrical components must be able to withstand solid contaminants, water splashes and intensive cleaning. Motors and gears have specific IP ratings because these are also affected by solid and liquid contaminants depending on the environment conditions. For instance, a gear motor with an IP54 rating is dust proof and provides protection against water splashed from all directions. For lower IP ratings, protection provided will be less and clean lubricants provide an edge in increasing productivity.

In the case of the water treatment industry, operators should note that electrical systems will react differently to freshwater than to salt water, leading to more extensive corrosion. Consideration must also be given to how often exposure occurs and where the system may be submerged. Even in some situations, previous testing may be required to ensure that an IP rating is appropriate for a particular industrial application.

Conclusion

Just like an iPhone user will not take underwater photos with a brand-new iPhone without checking its IP rating; similarly, ensuring that plant equipment can function optimally in its environment is an essential task for manufacturers and structural steel fabricators. Water and dust resistant products are essential for ensuring the continued productivity of manufacturing equipment and processes. To prevent component failures and unplanned downtime, manufacturers need to understand IP ratings to ensure that the selected equipment is suitable for its purpose – thus, ensuring a best fit!
