What is IEC 60068-2-18 test and guidance water?

IEC 60068-2-18 test and guidance water is a technical measurement method used in various industries to assess the ability of products to withstand the effects of water. This test, developed by the International Electrotechnical Commission (IEC), sets standards for environmental testing to ensure product reliability. In this article, we will explore the purpose and significance of IEC 60068-2-18 test and guidance water.

The Purpose of IEC 60068-2-18 Test

The main objective of the IEC 60068-2-18 test is to evaluate the performance of electrical and electronic equipment when exposed to water or moisture. The test measures the product's resistance to water ingress, its ability to function under wet conditions, and the durability of its packaging or enclosure against water-related hazards.

The IEC test standard specifies different degrees of protection provided by enclosures and assesses their ability to prevent water from entering the equipment. It helps manufacturers understand how well their products can withstand exposure to splashes, drips, sprays, or even immersion in water.

Testing Procedure

The IEC 60068-2-18 test involves subjecting the equipment to controlled water conditions to simulate real-world scenarios. The test apparatus typically includes a mechanical spray device and an optional oscillating tube device for specific applications.

Different categories are defined based on the intended usage and expected exposure to water. For each category, the test duration, water temperature, and other variables may vary. The test specimen is assessed by examining its functional performance and visual inspection before and after the test.

The results of the IEC 60068-2-18 test are classified as per the prescribed IP (Ingress Protection) codes. These codes consist of two digits - the first indicating the degree of protection against solid objects, and the second indicating the degree of protection against water.

Significance of IEC 60068-2-18 Test

The IEC 60068-2-18 test is crucial for manufacturers, as it helps them ensure their products meet quality, safety, and performance standards. By subjecting their equipment to this test, manufacturers can identify potential weaknesses, make necessary design improvements, and enhance the overall reliability of their products.

This test is especially important for industries where equipment may be exposed to water, such as automotive, aerospace, consumer electronics, and outdoor electrical installations. Compliance with the IEC 60068-2-18 standard enhances customer satisfaction and trust in the product's ability to withstand environmental conditions.

In conclusion, the IEC 60068-2-18 test and guidance water is an essential testing method used to assess the resistance of electrical and electronic equipment to water. Manufacturers who comply with this standard can demonstrate the reliability and durability of their products. By ensuring that products can withstand water exposure, they provide customers with confidence in their ability to function effectively even in wet conditions.
