Ingress Protection (IP Code) Testing – IP05: Water Jet Protection

IP05 testing is essential for assessing a product’s ability to withstand water jets and large object impacts. This type of testing is particularly important for industrial and outdoor products, which are often exposed to high-pressure water. It helps to verify that these products can endure such rigorous conditions without compromising their functionality.

As a certified IP Code testing laboratory, we realize the importance of ingress protection water spray testing. Meeting ingress protection compliance requirements can be difficult. We understand the challenges and guide companies through the process.

Keystone’s proven process helps avoid product launch delays. We are in constant communication throughout the entire compliance testing process. Our engineers take a consultative approach so customers can focus more on R&D and the marketing of their product.

Summary of IP 05 Ingress Protection Testing

Within the spectrum of the International Protection (IP) Marking system, overseen by the International Electrotechnical Commission (IEC), IP05 testing occupies a crucial space. This testing standard is a part of the IP rating system, a global framework that defines the levels of sealing effectiveness of electrical enclosures against intrusion from foreign bodies and moisture.

The IP05 rating specifically addresses the enclosure’s resistance to water jets and large solid objects.

Understanding IP05 Testing

IP05 rating involves two key parameters:

Large Object Protection (First Digit – ‘0’)

This test states that there is no protection provided against solid objects.

Water Jet Protection (Second Digit – ‘5’)

This parameter assesses the enclosure’s capacity to resist water projected by a nozzle against the enclosure from any direction.

IP05 Laboratory Testing Procedures

The methodology for IP05 testing is precise and uniform:

Test for Large Object Protection: There is no testing procedure associated with the first digit ‘0’ in an IP rating. This is because it indicates that the product offers no protection against solid objects.

Test for Water Jet Protection: Water is projected at the enclosure from a distance of 2.5 to 3 meters, using a nozzle with a 6.3 mm diameter. The test involves a water volume of 12.5 liters per minute and a duration of at least 3 minutes.

Importance of IP05 Testing

Robustness in Harsh Environments

IP05 testing ensures that products can withstand harsh conditions, particularly in industrial and outdoor settings where high-pressure water jets are common.

Safety and Reliability

Products passing IP05 tests are safer and more reliable, able to operate effectively despite exposure to water jets and large objects.

Consumer Confidence and Market Compliance

A product with an IP05 rating demonstrates compliance with international standards and builds consumer confidence in its durability.

Industrial Relevance

IP05 testing is vital for products in sectors where high-pressure water jets are used or where products might be exposed to such conditions.

Industry Applications

IP05 testing is crucial in several industries:

Industrial Equipment: For machinery and tools used in environments where high-pressure water jets are present.

Outdoor Electrical Devices: For items like outdoor power washers and garden tools that are exposed to water jets.

Construction and Marine Equipment: In sectors where equipment is regularly subjected to water jets and large objects.

Expert IP 05 Ingress Protection (IP Code) Testing Laboratory

IP05 testing plays a pivotal role in certifying that products are capable of withstanding the rigors of water jets and large object impacts, crucial for industrial and outdoor applications. This testing is not only a measure of product durability but also a testament to its safety and reliability in demanding environments.

As technologies evolve and new challenges emerge, the standards and procedures for IP05 testing will need to be continually updated and refined to ensure that they remain effective and relevant.

Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. In addition to IP05 testing, Keystone has a full scope of testing equipment to provide all of the IP Code tests from IP10 to IP69K. Our team strives to give our customers more time and energy on product development instead of testing.
