Rain Test Chambers are closed water ingress test equipment consisting of a series of waterproof test apparatuses for testing from IPX1 to IPX6K and IPX9/9K. They allow the specimens to be exposed to various levels of rainy environments, from vertically falling water drops to powerful water jets, to determine the waterproof performance of electrical equipment. Specifically, the waterproof performance here is indicated by the extent of protection provided by an enclosure against the ingress of water, causing no harmful effects on the equipment.

The rain test chambers play a very important role in the IPX waterproof test on electrical equipment. They are in accordance with IEC 60529, ISO 20653, DIN 40050-9 and other standards. The following content will show you the classification and more knowledge about rain test chambers.

What is Rain Test Chamber?

The rain test chamber adopts a box-type structure, which provides a realistic simulation of various rainy environments such as dripping, spraying, splashing, and jetting that electrical products and their components may be subjected to during transportation and use to determine the degree of protection provided by enclosures against water.

The rain test chamber features a closed test space to accommodate specimens and corresponding assemblies and an automatic water circulation system. It allows testing to continue in a confined space without the need to keep adding new water from the outside once the water for circulation is provided, thus not wetting the surrounding objects and saving water resources throughout the test. Unlike the open-type water ingress test equipment requiring a picky test site, the rain test chamber can assist you in performing waterproof tests anywhere in the laboratory.

According to the different requirements of the test standards, the rain test chamber is divided into many different types. They are mainly used in waterproof testing of outdoor lighting, signal devices, consumer electronics and automotive lighting housing.

What Are the Waterproof Testing Standards?

Among the many standards for waterproof testing of electrical equipment, the most commonly used and internationally recognized standards are IEC 60529, ISO 20653, and DIN 40050-9. IEC 60529 is formulated by the International Electrotechnical Commission. ISO 20653 is formulated by the International Organization for Standardization. DIN40050-9 is formulated by the German institute for standardization. All three standards have detailed instructions and descriptions for the classification of IPX waterproof test levels, testing equipment, test requirements, and test methods.

The biggest difference between the three standards on the waterproof test is the classification of the degrees of protection against ingress of water. ISO 20653 and DIN 40050-9 have IPX4K and IPX6K test items with high pressurization, while IEC 60529 does not have these two test items. The last item of ISO20653 and DIN40050-9 about waterproofing is IPX9K, while IEC60529 is indicated by IPX9 instead of IPX9K, but the contents of the two are almost the same.
