Electronic devices’ resilience to environmental elements is crucial. Various standards often measure this resilience, particularly the IP (Ingress Protection) rating system. 

The IP rating system not only informs consumers about the robustness of their devices but also serves as a critical benchmark for manufacturers during the design and production stages. 

This article aims to delve into the specifics of the IP63 rating, explaining what it means, how it is part of the broader IP rating system, and its implications for both consumers and manufacturers.

Understanding the IP Rating System

IP Rating System

Origins and Definition

The IP rating system is a globally recognized standard used to define levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies and moisture. 

Originating from the International Electrotechnical Commission (IEC), specifically standard IEC 60529, the IP code classifies and rates the degree of protection provided by mechanical casings and electrical enclosures. 

This system helps assess a device’s suitability for various environmental conditions that it might encounter during its operational life.

How the IP Rating is Structured

The structure of the IP rating is relatively straightforward yet informative. Each IP rating consists of two digits that follow the letters ‘IP.’ 

The first digit indicates the level of protection the enclosure offers against solids (dust and debris), ranging from 0 (no protection) to 6 (dust-tight). 

The second digit describes the level of protection against liquids, ranging from 0 (no protection) to 9 (protection against high-temperature water jets). 

These ratings provide a clear and concise understanding of a device’s durability in various environmental conditions, enabling consumers to make more informed purchasing decisions and manufacturers to design products tailored to specific needs and environments.

The Significance of the IP63 Rating


Explanation of Each Digit in IP63

The ‘6’ in IP63 signifies that the device is completely protected against dust. It means that the enclosure is so tightly sealed that no amount of dust can penetrate it, ensuring that the device’s internal components are safe from airborne particles. 

The ‘3’ indicates that the device can withstand water falling as a spray at any angle up to 60 degrees from the vertical. This level of protection ensures that the device can handle spraying water, which might occur during light rain or in cleaning processes, without suffering damage.

Practical Implications of the IP63 Rating

With its specific characteristics, the IP63 rating is particularly suited to environments where dust is prevalent but where only occasional exposure to water is expected. 

This makes it ideal for certain industrial tools and lighting fixtures in environments like woodworking or ceramic studios, where dust levels are high, and the equipment must be robust enough to withstand these conditions without failure. 

Consumers purchasing devices with an IP63 rating can be assured of their resistance to dust ingress, although they should be aware that these devices are not suited for submersion or exposure to heavy rain.

Comparison with Other IP Ratings

Higher Protection Ratings like IP67 or IP68

Devices with IP67 and IP68 ratings offer more extensive protection against water, including immersion. IP67 guarantees protection against temporary immersion in water (up to 1 meter for 30 minutes), and IP68-certified devices are protected against continuous submersion in water under conditions specified by the manufacturer. 

These ratings are critical for devices intended for use in or near water bodies or exposed to various weather conditions.

Lower Ratings and Their Use Cases

Lower IP ratings, such as IP54 and IP55, offer limited protection against dust and water splashes. These devices are suitable for indoor environments where some dust and moisture exposure occurs but neither element is heavily present. Understanding these distinctions helps consumers choose devices that best fit their environment and usage requirements.

Industries and Applications of IP63 Rated Devices

IP63 Rate

Consumer Electronics

In consumer electronics, the IP63 rating is less common than IP ratings offering higher water resistance, such as IP67 or IP68. 

This is due to the general consumer expectation that electronic devices, like smartphones and wearable tech, withstand more than just sprays of water. Many users expect significant water resistance to protect against accidental submersion.

Industrial and Commercial Use

In contrast, in industrial settings, the IP63 rating has substantial relevance. Devices designed for dusty but occasionally damp environments can perform optimally with an IP63 rating. 

This includes certain sensors and electrical housings used in manufacturing processes where they may be exposed to water spray but predominantly face dusty conditions.

Challenges and Considerations for Manufacturers

Balancing Cost and Protection

One of the primary challenges manufacturers face is balancing the costs of implementing high-level IP ratings against the actual needs of the device’s intended operating environment. Achieving higher IP ratings often requires more expensive materials and complex manufacturing processes, which can increase the overall cost of the device.

Regulatory and Safety Standards

Manufacturers must also consider the regulatory and safety standards that apply to their products, especially those sold in international markets. Devices intended for use in hazardous or extreme environments must adhere to stringent standards to ensure safety, functionality, and durability.

Future Trends and Innovations

Advances in Materials and Technology

The future of IP ratings lies in the advancements in materials science and sealing technology. Innovations in these areas could allow for even higher levels of protection without compromising device functionality or significantly increasing costs.

Increasing Consumer Awareness

As consumers become more knowledgeable about what IP ratings entail, their expectations for device durability and environmental resistance are also rising. This shift in consumer awareness is pushing manufacturers towards products with higher IP ratings, influencing future designs and manufacturing practices.

Frequently Asked Questions

1. What does an IP63 rating mean for daily-use electronics like smartphones and wearables?

An IP63 rating means the device is fully dust-proof but only protects against light water sprays. For devices like smartphones, which may face immersion, higher ratings like IP67 or IP68 are recommended.

2. Can IP63-rated devices be used outdoors?

IP63-rated devices are suitable for dry, dusty outdoor environments but are not ideal for heavy rain or wet conditions.

3. How do manufacturers test for IP63 compliance?

Manufacturers test IP63 compliance by subjecting devices to a dust-tightness test and water spray from various angles, ensuring no harmful effects occur.

4. Is an IP63 rating suitable for industrial settings?

Yes, an IP63 rating is ideal for industrial environments with high dust exposure and occasional water sprays, such as in woodworking or ceramics industries.


The IP63 rating serves a specific purpose in the vast landscape of IP ratings. By understanding what this rating entails and its appropriate applications, both consumers and manufacturers can make more informed decisions regarding the environmental durability of electronic devices. 

As technology evolves and environmental conditions change, the importance of such standards will only grow, further influencing the design and functionality of future electronic innovations.
