Certification for Electrical Equipment Durability Testing

The electrical equipment industry is one of the most rapidly growing sectors globally, with new innovations emerging every day. However, the durability and reliability of these products are crucial factors that determine their performance and lifespan. As a result, manufacturers and testing laboratories have to adhere to strict regulations and standards to ensure that electrical equipment meets the required safety and performance criteria.

What is Electrical Equipment Durability Testing?

Electrical equipment durability testing involves subjecting products to various environmental conditions and physical stresses to assess their reliability and performance under different operating scenarios. This type of testing helps manufacturers identify potential issues, improve product design, and reduce warranty claims and returns. The test procedures for electrical equipment typically involve exposure to:

  • Temperature fluctuations

  • Humidity levels

  • Vibration frequencies

  • Shock and impact loads

  • Power surge and transient conditions


    • Standards and Certifications

    There are several international standards and certifications that govern the durability testing of electrical equipment. Some of these include:

  • IEC 60068-1 (Environmental Testing Part 1: General Requirements)

  • IEC 60068-2 (Environmental Testing Part 2: Test Methods)

  • UL (Underwriters Laboratories) 943 (Standard for Safety of Electrical Appliances and Equipment)

  • ETL Mark (Interteks Certification Mark)


    • Benefits of Certifying Electrical Equipment Durability

    Certification is essential to ensure that electrical equipment meets the required safety and performance standards. Some benefits of certifying electrical equipment durability include:

  • Enhanced product reliability: Certification ensures that products can withstand various environmental conditions and physical stresses, reducing the risk of failures and warranty claims.

  • Improved market credibility: Products with certifications are more attractive to customers and can help manufacturers gain a competitive edge in the market.

  • Reduced costs: Certification can help manufacturers avoid costly rework or redesigns due to non-compliance issues.

  • Compliance with regulations: Certifications ensure that products comply with relevant laws and regulations, reducing the risk of fines or penalties.


    • How to Achieve Certification

    Achieving certification involves several steps:

    1. Conduct a product audit: Manufacturers need to conduct an internal review of their product design, testing procedures, and quality control processes.
    2. Develop a test plan: A comprehensive test plan should be developed to ensure that the product meets the required standards and certifications.
    3. Perform testing and evaluation: Testing and evaluation are carried out in accordance with the developed test plan.
    4. Submit documentation for certification: Manufacturers submit their test reports, product documentation, and other relevant information to the certifying body.

    Detailed Information on IEC 60068-1 and 2 Standards

    Here are two detailed paragraphs explaining IEC 60068-1 and 2 standards:

  • IEC 60068-1: General Requirements


    • The IEC 60068-1 standard provides general requirements for environmental testing. It outlines the conditions under which electrical equipment should be tested, including temperature, humidity, vibration, shock, and power surge. Manufacturers must ensure that their products meet these requirements to achieve certification.

    The standard also specifies the test procedures, sample sizes, and acceptance criteria for each test. For example, manufacturers may need to perform a 1000-hour humidity test at 40C and 90 relative humidity or a 10g vibration test on 10-500 Hz frequency range.

  • IEC 60068-2: Test Methods


    • The IEC 60068-2 standard outlines the specific test methods for environmental testing. It includes:

    Temperature tests: Tests are conducted to assess the products performance at various temperature ranges, including:

    Temperature cycling (e.g., -40C to 85C)

    Storage at elevated temperatures

    Thermal shock testing

    Humidity tests: Products are exposed to different humidity levels and durations to assess their resistance to moisture ingress.

    Vibration tests: Equipment is subjected to various vibration frequencies and amplitudes to determine its ability to withstand mechanical stress.

    QA Section

    Here are some additional questions and answers:

  • Q: What is the primary purpose of electrical equipment durability testing?

    • A: The primary purpose of electrical equipment durability testing is to assess the reliability and performance of products under different operating scenarios.
