Technology and Performance Testing
Materials and Chemical Restrictions
The materials and chemicals used in the product must comply with EU restrictions, such as limiting the use of harmful substances to protect user health and the environment.
Performance Requirements
Depending on the product's purpose and characteristics, it may need to meet specific performance requirements, such as energy efficiency, noise levels, reliability, etc.
Testing and Evaluation
Manufacturers need to test and evaluate the product to prove it meets relevant technical specifications and performance requirements. These tests may include material testing, functional testing, and safety testing.
Documentation and Labeling
Technical Documentation
Manufacturers need to prepare detailed technical documentation, including design files, test reports, user manuals, etc. These documents should record information about the product's design, manufacturing, and testing to prove it meets CE certification requirements.
CE Marking
The CE mark must be correctly applied to the sanitary butterfly valve, following the relevant marking regulations. The use of the CE mark indicates that the product complies with European regulations and can be freely circulated in the European market.
EC Declaration of Conformity
