This article explains aboutIP protection standards and detection methodscontent.

Recently, a friend recommended to Xiao Li a customer in the smart wear industry who needed solutions and equipment for sealing testing of watches.

Customer's requirements: Completely prohibit dust from entering, and ensure that the product can be immersed under 100m of water for 1 hour without water entering the watch. Combined with the IP protection level (as shown in the table below), it is determined that the dustproof and waterproof level of the product to be tested needs to be IP68.

Equipment selection:

The dustproof test can be carried out using a dustproof test chamber.

Waterproof testing can be carried out in the following four ways.

When selecting a testing method, the corresponding equipment is generally selected according to the protection level to perform waterproof testing on the product to be tested.

As can be seen from the above, customer needs can be detectedIP68 waterproof level testing equipment, so Xiao Li recommended the use of air tightness testing equipment to customers.

Air tightness testing equipment

The air tightness detector is a device that compresses gas, simulates water pressure, and detects leakage of the product to be tested through the pressure drop method or differential pressure method.

The pressure drop method refers to detecting changes in gas pressure by injecting air at constant pressure and balancing it. The air tightness and waterproof tester system obtains leakage values ​​through a series of sampling, calculations, and comparisons, and compares some data with set parameters to give a qualified or unqualified judgment result.It has a wide range of applications, and there are many types of benchmark air tightness testing equipment.

The differential pressure method tests the product to be tested and the standard product at the same time, compares the leakage values, and calculates the judgment result through a program.Suitable for products with high air tightness requirements and volatile products.

The final solution given by Xiao Li is:

Recommended instrument: Hirays HC classic series detector

Instructions for use: Customize the corresponding molds and tooling according to the shape and structure of the watch.

Install the mold on the customized tooling, and then place the product to be tested into the mold.

Using the differential pressure detection method, select the already set program (certified by a certain amount of sample experiments in the early stage), and you can start the detection.The instrument will definitely determine whether the product under test is OK or NG according to the set program.

Test process: Clamping → Start → Stabilize voltage → Test → Deflate → Remove the product.
