Ingress Protection (IP Code) Testing – IP22: Finger-Sized Object & Tilted Drip Water Protection

IP22 testing is a critical evaluation for assessing a product’s ability to protect against the entry of objects as large as 12.5mm in diameter (about the size of an adult finger) and to withstand water dripping at an angle. This standard is particularly vital for products likely to be used in environments where there is a risk of exposure to angled water drips, such as light rain or splashes, in addition to the threat posed by small object intrusion.

The IP22 rating is instrumental in ensuring the safety and functionality of these products under such specific conditions.

When products do not meet the requirements, we assist with finding solutions. Additionally, Keystone provides the peace of mind that all of your needs will be met under one roof. Keystone Compliance partners with customers to achieve environmental product compliance.

Summary of IP 22 Ingress Protection Testing

The IP22 testing forms part of the comprehensive International Protection (IP) Marking system, overseen by the International Electrotechnical Commission (IEC). This system classifies and rates the degree of protection provided by enclosures for electrical equipment against various external factors, including solid objects and moisture.

Specifically, the IP22 rating addresses the protection level against finger-sized objects and water ingress at a tilted angle.

Understanding IP22 Testing

IP22 testing includes two main aspects:

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

This test ensures that enclosures can prevent the entry of objects that are 12.5mm in diameter, safeguarding against accidental contact with hazardous parts.

Tilted Drip Water Protection (Second Digit – ‘2’)

This part of the test assesses the enclosure’s effectiveness in preventing water ingress when subjected to water drips at a 15-degree angle from the vertical.

IP 22 Laboratory Testing Procedures

The methodology for IP22 testing is rigorous and precise:

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

Test for Tilted Drip Water Protection: The product is subjected to water dripping at an angle of 15 degrees from the vertical. This simulates the effect of rain or splashes hitting the product at an angle, ensuring that no harmful quantity of water can penetrate the enclosure.

Importance of IP22 Testing

Enhanced Safety and Reliability

IP22 testing is essential for ensuring that products are safe from small object penetration and angled water exposure, enhancing their overall reliability.

Consumer Trust

Products that meet the IP22 standard provide assurance to consumers about their durability and safety in environments with potential water exposure and human interaction.

Compliance with Safety Regulations

Adhering to the IP22 standard demonstrates a product’s compliance with important safety and operational regulations.

Suitability for Varied Applications

The IP22 rating is crucial for products used in domestic, commercial, and industrial settings where there is a likelihood of exposure to tilted water drips and contact with non-technical personnel.

Industry Applications

IP22 testing is particularly relevant for:

Consumer Electronics: In household and office environments where devices are exposed to angled water drips and interaction with users.

Industrial Control Panels: Where equipment must be safeguarded against human contact and environmental factors such as water splashes.

Public Infrastructure: For electrical installations in accessible areas where tilted water exposure and human contact are possible.
