Power adapter salt spray test

Power adapter salt spray test is an important quality detection method designed to simulate the

harsh environment (e. g. high salinity, moisture, etc.) encountered in long-term use to evaluate its corrosion resistance and performance.

Test purpose

The main purpose of the power adapter salt spray test is to detect the corrosion resistance of the power adapter in a high salinity environment and the impact on the appearance and electrical performance of the power adapter in this environment.

Through testing, we can assess the quality and reliability of the power adapter, so as to ensure that it can work stably and reliably in a variety of harsh environments.

Test environment and methods

testing environment:

The test needs to be conducted in an environment with high salinity, usually using a special salt spray test box.

Add a certain percentage of saline (such as 5% concentration) to accelerate the corrosion process of the material.

Test method:

Place the power adapter to be tested in the salt spray test box and connect the load and power supply.

Set the temperature and humidity conditions in the test box, generally in accordance with the relevant standards or customer requirements.

Start the salt spray tester and spray the saline solution on the surface of the power adapter for continuous salt spray.

At different stages of the test, observe the appearance changes of the power adapter, including no signs of corrosion on the surface, color changes, etc.

Use the measuring equipment to test the circuit of the power adapter, and check whether the voltage output, stability and other electrical performance are affected.

Test standards and procedures

Power adapter salt spray test follows a series of international and domestic standards, such as IEC60068-2-11, IEC60068-2-52, GB / T 2423.17, GB / T 2423.18, etc.

The test process generally includes:

Prepare the test equipment and the saline solution.

Place the power adapter in the test box and connect the relevant equipment.

Set the test parameters (such as temperature, humidity, spray time, etc.).

Start the test and do a continuous salt spray.

Observe and record the appearance and electrical performance changes of the power adapter regularly during testing.

After the test, take out the power adapter for quality assessment and issue the test report.

Test results and assessments

The corrosion resistance and performance of the power adapter in high salinity environment can be obtained by salt spray test.

Qualified power adapters should be able to maintain a good appearance and stable performance, while the unqualified products may appear corrosion damage, electrical failure and other problems.

The testing organization will issue a detailed test report according to the test results, including the test methods, test conditions, test results and evaluation opinions, etc.

Electric blankets must obtain CE certification to export to the EU

  CE certification is a mandatory certification mark for products entering the European market indicating that the product meets the basic requirements of the EU's Technical Coordination and Standardization New Method Directive. The CE certification access model adopted by the EU market for electric blankets includes the following five parts: Low voltage instruction (LVD 2014/35/EU): Ensure the safe use of electric blankets under low voltage. Electromagnetic Compatibility Directive (EMCD 2014/30/EU): to ensure that the electric blanket does not produce electromagnetic interference to other electronic devices when used. Energy efficiency Directive (ErP): requires electric blankets to meet certain energy efficiency standards to reduce energy consumption. Directive to limit the use of certain harmful components in electronic and electrical products (RoHS): limits the use of certain harmful substances, such as lead, mercury, hexavalent chromium, etc., in electric blankets. Electronic a...

C-tick authentication concept A/c-tick is A certification mark for Communications equipment issued by the Australian Communications Authority (ACA).Manufacturers and importers must follow the next step in using A-Tick: : 1. Product implementation ACAQ technical standard test 2. Register the use of A/C-Tick to ACA 3. Fill in the Declaration of Conformity Form and keep the product with the record C - tick certification In communication products or equipment with A/C - the identity of the Tick marks (label) 5, sales to consumers A - Tick only applies to communication products, electronic products, mostly apply C - Tick, but electronic products if the application is A - Tick, do not need to apply for the C - other Tick.Since November 2001, EMI in Australia/New Zealand has applied for a merger;If the product is to be sold in the two countries, the following documents must be in place before marketing, in case the authorities of the Australian Communications Authority or the Ministry of Ec...
