Ingress Protection Testing

What is Ingress Protection (IP)?

Ingress Protection (IP) ratings indicate the level of protection an electronic or electrical enclosure offers against dust, moisture, insects, and other foreign objects. IP testing is essential to ensure that a product's enclosure can resist these elements, particularly in environments with extreme weather conditions.

While ingress protection testing is not mandatory, many specifiers and purchasers request an IP rating to confirm the suitability of lighting products for outdoor or industrial applications. This testing validates that your product's enclosure can effectively withstand moisture and dust, ensuring reliable performance in challenging conditions. By adhering to the IEC 60529 standard for IP testing, you can confidently support your performance claims.

An IP rating can serve as a crucial proof of product quality, providing a competitive edge in the market. For deeper insights into water and dust ingress testing and its relevance to lighting products, download our informative white paper below.

What is IEC 60529?

IEC 60529, also known as the "Degree of Protection Provided by Enclosures," is a widely recognized standard that assesses the environmental protection capabilities of electrical equipment, including lighting products that are permanently installed and not portable. This standard was established to rate enclosures of electrical and electronic devices based on their resistance to dust and liquids, as well as the accessibility of potentially hazardous components within the enclosure. Compliance with IEC 60529 ratings allows manufacturers to market their products in Europe and other regions outside of North America.

The Ingress Protection (IP) code is composed of two digits:

The first digit indicates the level of protection against solid objects, such as dust, and is rated on a scale from 0 to 6. The second digit specifies the level of protection against fluids or water, using a scale from 0 to 9.

Understanding IEC 60529 ratings is essential for ensuring that your products meet industry standards and are suitable for various environmental conditions.

Dust (First Number)

• IP 0x - No Protection

• IP 1x - Objects > 50mm

• IP 2x - Objects > 12mm

• IP 3x - Objects > 2.5mm

• IP 4x - Objects > 1mm

• IP 5x - Dust Protected (Vacuum)

• IP 5x - Dust Protected (Non-Vacuum)

• IP 6x - Dust Tight

Moisture (Second Number)

• IP x0 - No Protection

• IP x1 - Protected Against Water Dripping Vertically

• IP x2 - Protected Against Dripping Water (15º tilted)

• IP x3 - Protected Against Sprayed Water

• IP x4 - Protected Against Splashed Water

• IP x5 - Protected Against Water Jets

• IP x6 - Protected Against Powerful Water Jets

• IP x7 - Protected Against Effects of Temporary Immersion

• IP x8 - Protected Against Continuous Immersion

• IP x9 - Resistant to Water from High-Pressure and Steam Jet Cleaning

How is Ingress Protection Testing Conducted?

Ingress Protection testing primarily evaluates a product's resistance to dust and water, determining how well the enclosure can withstand these environmental challenges.

Dust Testing

Dust testing, often referred to as solid testing, assesses how well an enclosure can prevent the ingress of solid particles. Many electronic devices feature openings such as charging ports, speaker grills, and microphone holes, which can attract and trap dust. Microscopic dust particles can infiltrate these openings, potentially causing errors, malfunction, or safety hazards.

To conduct dust testing, the device enclosure is placed inside a specialized dust chamber, which varies in size to accommodate different devices. These chambers can contain a range of solid particles, from sand to fine dust, depending on the specific testing requirements and standards.

During the test, dust particles are fully suspended within the chamber, either by physically shaking the chamber or using air blowers. After the testing period, the device is removed from the chamber, and the enclosure is opened to assess the amount and size of dust ingress. The results of this evaluation determine the device's IP rating.

There are two primary dust ratings:

• IP5X: Indicates that dust ingress is not significant enough to interfere with the operation of the electronics.

• IP6X: Signifies that the enclosure is completely sealed against dust ingress.

Understanding these ratings is crucial for demonstrating the reliability and durability of your products in challenging environments.

Water Testing

Water testing evaluates a device's ability to resist ingress from water, using water as the standard liquid. This testing is conducted through two primary methods: spraying and submersion.

• Spraying: In the spraying method, water jets are directed at the device from all angles. These jets are typically applied at specified pressures, and the duration of the spraying can range from 3 to 30 minutes, depending on the device being tested. After the spraying period, the device is removed from the testing area, and the enclosure is inspected for any signs of water ingress.

• Submersion: The submersion method involves placing the device in a watertight chamber filled with water. The water level can vary, and the device is left submerged for different lengths of time. Once the test is complete, the device is removed, and the interior is checked for any water presence.

Water ratings are categorized from IPX0 to IPX8: IPX0 indicates no protection against water. IPX8 signifies that the device can withstand water ingress at certain depths and for specified durations. Understanding these water ratings is essential for verifying the durability and reliability of your products in wet conditions.
