Ingress Protection (IP Code) Testing – IP35: Tool-Sized Object & Water Jet Protection

IP35 testing is a critical measure for evaluating a product’s ability to safeguard against the entry of objects as small as 2.5mm, akin to small tools or thick wires, and its resilience to water jets.

This standard is especially important for products operating in environments where they might be exposed to directed water jets and the risk of intrusion by small tool-sized objects. 

As a certified IP Code testing laboratory, we realize the importance of – testing. Meeting ingress protection compliance requirements can be difficult. We understand the challenges and guide companies through the process. When products do not meet the requirements, we assist with finding solutions. Additionally, Keystone offers immediate emergency scheduling. Our engineers take a consultative approach so customers can focus more on R&D and the marketing of their product.

Summary of IP 35 Ingress Protection Testing

As part of the International Protection (IP) Marking system, administered by the International Electrotechnical Commission (IEC), the IP35 rating provides an important benchmark for the level of protection offered by electrical enclosures.

The IP35 rating is crucial in ensuring that these products can maintain their operational integrity and safety under such challenging conditions, which is vital for a range of applications in both industrial and commercial settings.

It specifically addresses the product’s resistance to objects as small as 2.5mm in diameter and its ability to withstand water jets, ensuring the safety and durability of the equipment.

Understanding IP35 Testing

IP35 testing encompasses two key areas of protection:

2.5mm Tool-Sized Object Protection (First Digit – ‘3’)

This test assesses whether the enclosure can prevent the entry of small objects that are 2.5mm in diameter, effectively protecting against accidental contact with internal hazardous components.

Water Jet Protection (Second Digit – ‘5’)

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

IP 35 Laboratory Testing Procedures

The methodology for IP35 testing is both rigorous and thorough:

Test for 2.5mm Tool-Sized Object Protection: This involves attempting to insert a 2.5mm diameter object into the product’s enclosure. The object should not be able to fully penetrate or come into contact with any dangerous parts inside the product.

Test for Water Jet Protection: The product is exposed to water jets from a nozzle at various angles. This test simulates the effect of water jets, assessing the enclosure’s ability to protect its internal components from water under pressure.

Importance of IP35 Testing

Enhanced Safety and Durability

IP35 testing is essential for ensuring that products are robust against small object penetration and water jet exposure, enhancing their overall reliability for various uses.

Consumer Trust

Meeting the IP35 standard reassures consumers and users about the product’s durability and safety in conditions involving potential water exposure and physical contact.

Compliance with Safety Regulations

Adherence to the IP35 standard demonstrates a product’s commitment to safety and operational standards, particularly in the electrical equipment sector.

Suitability for Various Environments

The IP35 rating is crucial for products used in settings where they are exposed to water jets and interaction with small tools.

Industry Applications

IP35 testing is particularly relevant in:

Industrial Machinery and Equipment: Where protection against small tools and environmental factors like water jets is necessary.

Commercial and High-End Consumer Electronics: For devices used in environments where exposure to water jets and accidental contact are possibilities.

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