Reliability testing

Reliability testing is an activity to assess the maintenance of functional reliability of a product over the specified life period in all environments including intended use, transportation or storage.

By exposing the product to natural or artificial environmental conditions, to evaluate its performance under the environmental conditions of actual use, transportation and storage, and analyze the influence degree of environmental factors and their mechanism of action.

Purpose

1. Evaluation the performance and reliability of the product: Through the reliability test, a comprehensive evaluation of the performance and reliability of the product can be conducted to determine the performance and stability of the product under various conditions.

2. Find and solve problems: in the test process, problems and defects can be found in the product, so as to improve and optimize in time, improve the quality and reliability of the product, and reduce the failure and maintenance costs.

3. Meet customer needs: By meeting customers 'requirements for product performance and reliability, improve the market competitiveness of products, and increase customers' trust and satisfaction with products.

Test methods

1. Environmental test: test the performance and reliability of the product or system under different environmental conditions, including temperature, humidity, air pressure, vibration, shock and other environmental factors. These tests can help determine the ability of products to adapt to different environmental conditions.

2. Life test: A long operation and durability test of a product or system to assess its life and reliability. This test method usually needs to be conducted under simulated actual working conditions to obtain more accurate evaluation results.

3. Accelerated life test: Accelerated aging of products or systems in an environment beyond normal working conditions to shorten the test time and improve the test efficiency. This method can accelerate the aging process of the product, resulting in a faster evaluation of its reliability and longevity.

4. Fault tree analysis and fault tolerance technology: analyze the fault mode and fault impact of the product or system, and design the corresponding fault handling and fault tolerance mechanism to improve the reliability and availability of the system. These methods help to consider potential failures and take preventive measures at the product design stage.

Application area

Reliability testing is widely used in various fields, including but not limited to hardware, software and systems.

In hardware field, reliability testing can evaluate the durability, stability and security of electronic equipment; in software field, the stability, reliability and fault tolerance of software system; in system field, it can evaluate the integration, stability and reliability of the whole system.

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...
