Ingress Protection (IP Code) Testing – IP28: Finger-Sized Object & Extended Immersion

IP28 testing is a critical standard for assessing a product’s resilience against the entry of 12.5mm finger-sized objects and its ability to withstand prolonged immersion in water. This testing is particularly vital for products designed for use in environments where there is a high likelihood of extended submersion in water and exposure to small objects.

As a certified IP Code testing laboratory, we realize the importance of IP28 ingress protection testing. Meeting ingress protection compliance requirements can be difficult.

Summary of IP 28 Ingress Protection Testing

As part of the International Protection (IP) Marking system, overseen by the International Electrotechnical Commission (IEC), IP28 testing categorizes the degree of protection provided by enclosures against external factors such as solid objects and liquids.

The IP28 rating is essential for ensuring that these products can sustain their operational integrity and safety under such challenging conditions, which is crucial across a range of applications, from industrial to outdoor settings.

Specifically, the IP28 standard focuses on the product’s ability to prevent the intrusion of objects as large as 12.5mm in diameter and its capacity to endure extended periods of immersion in water.

Understanding IP28 Testing

IP28 testing involves two key protective measures:

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

This aspect of the test confirms that the enclosure can prevent the penetration of objects with a diameter of 12.5mm, safeguarding against accidental contact with hazardous parts within the product.

Extended Immersion Protection (Second Digit – ‘8’)

This part of the test assesses the product’s capability to resist water ingress during extended immersion, often under more severe conditions than standard immersion tests.

IP28 Laboratory Testing Procedures

The methodology for IP28 testing is comprehensive and stringent:

Test for 12.5mm Finger-Sized Object Protection: In this test, an object of 12.5mm diameter is used to attempt to penetrate the enclosure. The object should not be able to fully penetrate the enclosure or come into contact with any hazardous internal parts.

Test for Extended Immersion Protection: The product is submerged in water at a depth and for a duration specified by the standard, typically deeper and longer than the requirements for standard immersion tests. This test ensures that no harmful amount of water can penetrate the enclosure during this extended immersion period, protecting the internal components.

Importance of IP28 Testing

Enhanced Safety and Durability

IP28 testing is vital for ensuring that products are robust and safe from small object penetration and prolonged water immersion, enhancing their overall reliability and suitability for demanding environments.

Consumer Confidence

Products that meet the IP28 standard provide users with assurance of their durability and safety in conditions involving potential extended water exposure.

Compliance with Regulatory Standards

Adherence to the IP28 rating demonstrates a product’s commitment to safety and operational regulations, particularly in the electrical equipment sector.

Applicability in Various Environments

The IP28 rating is crucial for products used in settings where extended immersion is a possibility, such as in marine applications, outdoor environments, and certain industrial contexts.

Industry Applications

IP28 testing is particularly relevant in:

Marine and Underwater Equipment: For devices used in deep-sea exploration, marine research, or underwater operations where prolonged immersion is common.

Outdoor Electrical Installations: In environments where equipment is exposed to natural water bodies or subjected to flooding conditions.

Industrial Machinery: Especially in industries where machinery might be submerged for extended periods due to environmental or operational conditions.
