Chinas wind power equipment industry has achieved remarkable development in the past few years and has the strength to go global and explore overseas markets. However, different countries have differences in technical standards and certification requirements for wind power products, which has brought some challenges to Chinese wind power enterprises in the international market. The following are some major technical standards and certification requirements, especially in the EU market:

1. EU CE Certification:CE certification is the basic product safety regulation of the EU. It requires products to meet EU regulatory standards and allows them to be freely sold and used in the EU market.
2. EU Machinery MD Certification:This is the certification requirement for wind power equipment to enter the EU market as mechanical products. Products must undergo safety assessments in accordance with the requirements of the EU Machinery Directive, including different safety assessment requirements for ordinary machinery and hazardous machinery.
3. ISO3834 welding system certification:This is the certification for welding processes. It requires enterprises to integrate design, process, production, and quality assurance to form a mature welding quality system and ensure product quality requirements.
4. Steel structure CE certification - EN1090:This is the certification requirement for steel structures, covering the audit of the steel structure enterprise system. It mainly assesses the enterprises quality control ability to ensure that the product is consistent with the performance parameters promised by the manufacturer.
5. IEC61400-22 Wind Turbine Compliance Testing and Certification:This certification system conducts type certification, project certification, and design certification for wind turbines to reduce risks.
6. Specify the standard ISO 12944 for the coating anti - corrosion system of steel structures:This is the coating anti - corrosion requirement for offshore wind power equipment, ensuring the corrosion resistance of the unit in the marine environment.

As a wind power export enterprise, it is very important to understand and meet the requirements of technical regulations and standard certification procedures of various countries. This helps to break through foreign technical trade barrier restrictions and promote the circulation of products in the international market. At the same time, closely monitor the updates and changes of standards and certification requirements, adjust production processes and sales plans to meet the needs and requirements of different markets and further expand overseas markets.
