Ingress Protection (IP Code) Testing – IP01: Dripping Water Protection

IP01 Water Drip Testing

IP01 testing is crucial for assessing how well a product resists the ingress of large objects and the impact of water drips. This testing simulates everyday scenarios where electronics might encounter dripping water, ensuring that they remain functional and safe in such environments. Understanding how products perform under these conditions is essential for maintaining reliability and customer trust.

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.

Summary of IP 01 Ingress Protection Testing

IP01 testing is part of the broader International Protection Marking code, commonly referred to as the IP code. The IP code is an international standard, designated by the International Electrotechnical Commission (IEC), which classifies and rates the degree of protection provided by mechanical casings and electrical enclosures against intrusion, dust, accidental contact, and water.

Specifically, the IP01 rating addresses the protection of equipment against the ingress of solid foreign objects of 50 mm diameter and greater and vertically falling drops of water.

Understanding IP01 Testing

IP01 testing comprises two primary aspects: testing for protection against large objects (denoted by the first digit ‘0’) and protection against dripping water (denoted by the second digit ‘1’).

Large Object Protection (First Digit – ‘0’)

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

Drip Water Protection (Second Digit – ‘1’)

This test assesses the product’s ability to function effectively in the presence of vertically falling water drops. The test simulates a scenario where water drips vertically onto the product at a rate of 1 mm per minute for a duration of at least 10 minutes.

IP 01 Laboratory Testing Procedures

The testing procedures for IP01 are methodical and standardized to ensure consistent results:

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 Drip Water Protection: The enclosure is placed under a grid of water drips. Water is dripped onto the enclosure from a height of 200 mm above the top surface at a rate of 1 mm per minute.

The test duration is based on the surface area of the enclosure being tested, calculated at 1 minute for every square meter of the enclosure surface area, with a minimum of 10 minutes of testing.

Importance of IP01 Testing


IP01 testing ensures that the product is safe to use, especially where there might be exposure to large objects and water drips. It prevents accidents caused by electric shock or malfunction.

Product Reliability

Products that pass IP01 testing are more reliable in various environments, ensuring consistent performance and reducing the risk of damage from environmental factors.

Consumer Confidence

A product with an IP01 rating can enhance consumer confidence, as it indicates a level of quality and durability.

Compliance and Standards

Adhering to IP01 standards helps manufacturers meet legal and market requirements, which is crucial for global distribution and acceptance.

Industry Applications

The IP01 testing is relevant in numerous industries, including:

Consumer Electronics: For gadgets used in domestic environments where they may be exposed to water drips from condensation or spills.

Industrial Equipment: In factories or warehouses where large objects are common, and equipment may be exposed to water drips.

Outdoor Electrical Equipment: For devices used outdoors, though the protection from water drips is relatively minimal compared to higher IP ratings.

Expert IP 01 Ingress Protection (IP Code) Testing Laboratory

IP01 testing is a critical process in the lifecycle of a product, particularly in ensuring its safety and reliability against the ingress of large objects and water drips. While it provides a basic level of protection, it is essential for manufacturers to understand and meet these standards.

As technology advances, the standards and procedures for IP01 testing will continue to evolve, further enhancing the quality and safety of electrical and electronic products. Keystone has a full lab of test equipment which permits us to provide short lead times on scheduling. Our team strives to give our customers more time and energy on product development instead of testing.

In addition to IP10 testing, Keystone has a full scope of testing equipment to provide all of the IP Code tests from IP01 to IP69K.
