How Waterproof Testing Can Help Improve the Reliability of Electronic Devices

Waterproof testing is mainly aimed at electronic products and equipment that are used outdoors or in harsh environments. It simulates the rainwater environment under different weather conditions in nature to conduct waterproof testing on electrical and electronic products and equipment to verify their waterproof performance.

Waterproof testing is mainly based on the relevant waterproof level requirements in the shell protection level standard. Although the experiment may seem simple, it is an important method to determine whether the waterproof performance of the product meets the requirements,

The representation is IPXX, with the first characteristic number indicating the level of protection against approaching hazardous components and preventing the entry of solid foreign objects, and the second characteristic number indicating the level of protection against water entry. Used to assess whether the good working performance of the equipment or components can be guaranteed after or during the testing of the product casing and sealing components.

Purpose and significance of waterproof testing:
During the transportation and use of electronic products, they may be exposed to the rain of natural precipitation, condensation, leakage and falling water drops, similar to the water rushing caused by heavy rainstorm, spraying water system, and even flooded by water.

Water can damage the coating on the surface of products, accelerate metal corrosion, and reduce the strength of certain materials. It is the main cause of electrical insulation flashover or breakdown, resulting in short circuit damage to products; Water can also penetrate into the interior of the product and freeze, causing parts to malfunction or fail due to blistering or cracking; Water can also cause high humidity, thereby promoting mold growth, etc.

The main purpose of waterproof testing is to assess the waterproof ability of the shell, protective cover, and seal of the product that needs to be waterproof, in order to ensure that the product does not cause damage and has satisfactory performance under and after the influence of water.

Which electronic products require waterproof testing?
1. Naturally, it is a variety of outdoor electrical and electronic products. Outdoor lighting fixtures, including street lights, LED advertising light boxes, outdoor lighting power supplies, outdoor socket switches, and outdoor audio systems used in parks, exhibition halls, and other venues.

Furthermore, the municipal public facility electrical cabinets and their electrical components that can be seen everywhere when going out must pass the corresponding waterproof level test before they can be put into use, otherwise they can easily cause safety hazards.

2. Necessary transportation tools for travel, such as cars, trucks, motorcycles, electric vehicles, and related accessories. This is easy to understand. Transportation vehicles must adapt to various weather conditions, including rainwater, when driving outdoors.

Of course, there are all kinds of household appliances closely related to life, such as washing machines and kitchen appliances, and mobile phones, waterproof earphones, watches, electric toothbrush, electric razors, and so on.

The products listed above that require waterproof testing are only a small part, and there are tens of thousands of electrical and electronic products with waterproof performance used in daily life. Therefore, waterproof testing equipment specifically designed for waterproofing testing becomes even more important.

JL-X waterproof test machine is according to IEC60529:1989 +A1:1999 +A2：2013 《Degrees of protection provided by enclosures(IP Code)》, IEC60598, IEC60335 and IEC 60034-5, GB/T-2423.2, GB4208, GB7000.1. The JL-X includes the following test grades: IPX1, IPX2, IPX3, IPX4, IPX5, IPX6, IPX7 and IPX8 (Refer to page 51 of IEC60529). It is widely used in the authentication test organization for the products such as electrical & electronic products, LED luminaires as well as in the relevant quality control department for the waterproof detection of the enclosures protection grades.

The whole JL-X waterproof test system includes:
