IP2X Ingress Protection Testing

IP2X testing is a type of ingress protection testing that measures the level of protection a product provides against solid foreign objects that are smaller than 12.5mm in diameter. The IP2X rating indicates that the product is protected against the entry of any object that is larger than 12.5mm in diameter and longer than 80mm in length.

The IP2X testing process involves subjecting the product to a series of tests to ensure that it meets the requirements for protection against solid foreign objects. During the testing process, a jointed test finger is used to test the product’s enclosure for any openings that may allow the finger to enter.

The jointed test finger has a 12mm diameter and a rigid sphere of 12.5mm diameter. If the test finger is unable to enter the enclosure, the product is considered to have passed the test and is given an IP2X rating.

The IP2X rating is an important consideration for product designers and manufacturers when developing products for use in environments where small solid foreign objects may be present. 

This could include environments such as laboratories, food processing facilities, and medical facilities, where small particles of dust or other materials could cause contamination or damage to the product.

How is IP2X Testing Completed?

To test for IP2X, a test finger with a diameter of 12.5mm is used to probe the enclosure for any openings or gaps that could allow solid objects to enter. The jointed test finger is applied with a force of 10N to any opening or gap that is likely to permit the entry of a solid object.

The test is performed on all accessible surfaces of the enclosure, including the sides, top, bottom, and any doors or panels. The test finger is applied to any joints, seams, or other areas where openings or gaps are likely to occur.

If the test finger does not enter the enclosure or only enters to a depth of less than 80mm, the enclosure can be rated as IP2X. If the test finger enters to a depth greater than 80mm, the enclosure cannot be rated as IP2X.

It’s important to note that IP ratings are cumulative, so an enclosure that meets the requirements for IP2X also meets the requirements for IP1X. However, an enclosure that is rated as IP2X does not necessarily meet the requirements for higher IP ratings, which offer greater protection against smaller objects or dust.

How Does IP2X Testing Help Manufacturers?

IP2X testing evaluates the level of protection provided by an enclosure against the ingress of solid objects with a diameter greater than 12.5 mm.


IP2X testing is often required by regulatory bodies and standards organizations to ensure compliance with safety standards. By testing their products and demonstrating compliance with these standards, manufacturers can avoid costly fines and legal issues.

Quality Assurance

By subjecting their enclosures to IP2X testing, manufacturers can ensure that their products meet the level of protection they claim to provide. This helps to establish trust with customers and can lead to increased sales.

Design Improvement

IP2X testing can also help manufacturers identify weaknesses or design flaws in their enclosures, allowing them to make improvements and provide better protection to their customers. This can lead to higher quality products and a stronger reputation for the manufacturer.

Competitive Advantage

By achieving a higher IP rating, such as IP2X, manufacturers can differentiate their products from competitors and offer a unique selling point to customers.

By ensuring that a product meets the IP2X rating requirements, manufacturers can provide their customers with a product that is safe, reliable, and suitable for use in a wide range of environments and applications.

How to Obtain IP2X Ingress Protection Certification for Your Device or Enclosure?

Overall, IP2X testing is an important part of product development and design, particularly for products that are intended for use in environments where small solid foreign objects may be present.
