Ingress Protection (IP Code) Testing – IP25: Finger-Sized Object & Water Jet Protection

IP25 testing is a critical assessment for evaluating a product’s ability to protect against the intrusion of 12.5mm finger-sized objects and withstand water jets. This standard is particularly important for products operating in environments where exposure to directed water and contact with small objects are prevalent. The IP25 rating ensures that these products can maintain operational integrity and safety under such challenging conditions, which is crucial for a wide range of industrial, commercial, and outdoor applications.

When products do not meet the requirements, we assist with finding solutions. Keystone takes a consultative approach throughout the entire test program. We quickly turnaround comprehensive reports after the completion of the testing process.

Summary of IP 25 Ingress Protection Testing

Part of the International Protection (IP) Marking system established by the International Electrotechnical Commission (IEC), IP25 testing provides a means to classify the level of protection offered by electrical enclosures against external elements such as solid objects and liquids. Specifically, the IP25 rating focuses on the product’s resistance to objects about the size of an adult finger (12.5mm in diameter) and protection from water jets.

Understanding IP25 Testing

IP25 testing encompasses two significant protective aspects:

12.5mm Finger-Sized Object Protection (First Digit – ‘2’)

This aspect of the test ensures the enclosure can prevent the entry of objects that are 12.5mm in diameter, safeguarding against accidental finger contact and small object intrusion.

Water Jet Protection (Second Digit – ‘5’)

This part evaluates the product’s ability to resist water projected by a nozzle against the enclosure from any direction, simulating scenarios such as cleaning processes or heavy rain.

IP25 Laboratory Testing Procedures

The methodology for IP25 testing is detailed and methodical:

Test for 12.5mm Finger-Sized Object Protection: The test involves attempting to insert a 12.5mm diameter object into the enclosure. This object must not fully penetrate or come into contact with any hazardous components inside the product.

Test for Water Jet Protection: The product is subjected to water jets from a nozzle at varying angles. This test examines the enclosure’s capacity to prevent water from entering and potentially damaging the internal components or compromising safety.

Importance of IP25 Testing

Enhanced Safety and Reliability

IP25 testing is essential for ensuring products are safe from small object penetration and water jet exposure, enhancing their overall reliability and suitability for various environments.

Consumer Confidence

Meeting the IP25 standard reassures consumers and users about the product’s durability and safety in conditions involving water exposure and potential physical contact.

Compliance with Regulations

Adhering to the IP25 rating is indicative of a product’s compliance with important safety and operational standards, particularly in electrical equipment.

Suitability for Diverse Applications

The IP25 rating is crucial for products used in industrial, commercial, and outdoor settings where exposure to water jets and interaction with non-specialized personnel are likely.

Industry Applications

IP25 testing is particularly relevant in:

Industrial and Commercial Equipment: For machinery and devices where protection against water jets and human interaction is necessary.

Outdoor Electrical Installations: In settings where equipment is exposed to natural elements and requires robust protection.

Consumer Electronics: Especially for appliances and devices used in environments where water jet exposure and accidental contact are possible.
