Gas corrosion testing for electronic products

 Test purpose and significance:

The environment used in most products is in the atmosphere, while most corrosion occurs in the atmosphere, which contains corrosive components and corrosion factors such as oxygen, humidity, temperature changes and pollutants.

The atmospheric environment leads to the formation of water film on the metal surface, and the existence of H2S, SO2, NO2, Cl2 and other harmful gases in the atmosphere into the water film formed on the metal surface, as corrosive ions to accelerate the corrosion process.

In a certain temperature and humidity environment, use H2S, SO2, NO2, Cl2 and other harmful gases to accelerate the corrosion of the material or product, and reproduce the degree of damage suffered by the material or product within a certain time range.

Assessment the ability of material and protective layer to resist gas corrosion, as well as the process quality of similar protective layer, can also be used to assess the ability of some products to resist gas corrosion.

Application scope of testing:

Communication products and surrounding parts, automotive electronics, electronic components, connectors, metal materials, electronic electrician and other products of the protective layer and electronic and electrical products.

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...
