Ingress Protection (IP Code) Testing – IP67: Dust-Tight & Immersion Protection

IP67 testing is a crucial standard in product safety, designed to evaluate a product’s ability to provide complete dust-tight protection and withstand temporary immersion in water. This standard is particularly relevant for electrical enclosures and similar products used in environments where full protection against dust ingress and the risk of temporary submersion in water are essential.

Meeting ingress protection compliance requirements can be difficult. As an ISO 17025 accredited testing laboratory, we understand the challenges and guide companies through the process. 

Keystone provides the peace of mind that all of your needs will be met under one roof. When products do not meet the requirements, we assist with finding solutions. Additionally, we create an accurate test plan to eliminate expensive over-testing.

Summary of IP 67 Ingress Protection Testing

Part of the International Protection (IP) Marking system, managed by the International Electrotechnical Commission (IEC), IP67 testing provides guidelines for the level of protection offered by enclosures against dust and water.

This rating is critical for ensuring the safety and functionality of electrical equipment in environments prone to dust and temporary water immersion.

The IP67 rating ensures that these products can entirely prevent the entry of dust and are capable of protecting against water immersion, maintaining their operational integrity and safety in a variety of applications.

Understanding IP67 Testing

IP67 testing involves two key aspects of protection:

Dust-Tight Protection (First Digit – ‘6’)

This test evaluates the enclosure’s ability to completely prevent the entry of dust, ensuring the highest level of dust protection.

Temporary Immersion Protection (Second Digit – ‘7’)

This aspect of the test assesses the product’s ability to withstand temporary immersion in water under specified conditions, such as depth and duration.

IP67 Laboratory Testing Procedures

The methodology for IP67 testing is rigorous and comprehensive:

Test for Dust-Tight Protection: The enclosure undergoes testing in a dust-filled environment under controlled conditions to confirm that no dust particles can penetrate it, ensuring the internal components remain free from dust contamination.

Test for Temporary Immersion Protection: The product is immersed in water at a depth determined by the standard, typically around 1 meter, for a duration specified by the manufacturer, usually at least 30 minutes.

This test checks whether the enclosure can effectively prevent water from entering and causing damage to the internal electrical components during this period of submersion.

Importance of IP67 Testing

Maximum Equipment Safety

IP67 testing is essential for ensuring that electrical enclosures offer the highest level of protection against dust ingress and temporary immersion in water, thereby enhancing overall safety and reliability.

Reliability in Dusty and Wet Environments

The IP67 rating ensures the product’s functionality and longevity in environments where dust and temporary water immersion are significant concerns.

Consumer and User Confidence

Products meeting the IP67 standard provide users with assurance of their operational stability and safety in environments prone to dust exposure and temporary water submersion.

Compliance with Safety Standards

Adherence to the IP67 standard demonstrates a commitment to safety and quality in product design and manufacturing.

Industry Applications

IP67 testing is particularly relevant for:

Industrial Control Panels and Enclosures: In industries where dust is prevalent and exposure to temporary immersion in water is possible, such as in certain manufacturing sectors or outdoor settings.

Sensitive Electronics and Equipment: For electronics and precision instruments where dust ingress or temporary water immersion can cause malfunction or damage.

Commercial and Public Electrical Installations: In areas with high levels of ambient dust and potential for temporary immersion in water, where complete dust protection and temporary immersion resistance are necessary for safety and functionality.
