EN Testing: Categorized by Test Item
EN standard testing for curtain wall hardware is categorized by specific test items: mechanical testing (load-bearing capacity), durability testing (salt spray/aging), functional testing (opening/closing and sealing), and fire-resistance testing (based on product category). Industry experts note that evaluations are conducted item-by-item: mechanical tests cover load-bearing capacity and wind pressure resistance;
durability tests cover salt spray and aging; functional tests cover opening/closing and sealing; and fire-resistance tests are specific to the product category.
Comprehensive test reports are required, and the reports must be verified against the actual products.
Categorized by Test Item
- Mechanical testing: Load-bearing capacity/wind pressure resistance (mechanical) – Core requirement;
- Durability testing: Salt spray/aging (durability) – Critical requirement;
- Functional testing: Opening/closing/sealing (functional) – Supplementary requirement;
- Fire-resistance testing: By product category (fire safety) – Specialized requirement;
- Report verification: Matching reports to products – Verification step.
Key Evaluation Points
First, standard alignment: Ensure the EN standard (test item) matches the product to avoid incorrect testing.
Second, comprehensive testing: Ensure mechanical and durability tests are fully covered to avoid missing items.
Third, report verification: Ensure reports correspond to the actual products to prevent fraud.
Fourth, schedule planning: Allow sufficient time for the testing cycle to avoid delays.
Pitfalls to Avoid
First, “incorrect test items”: Choosing the wrong test items wastes money;
ensure standards match.
Second, “missing report items”: Missing items require re-testing;
ensure all tests are completed.
Third, “report falsification”: Falsified reports create safety hazards;
ensure reports are verified against the actual products.
Trends and Reminders
EN testing for curtain wall hardware is moving towards digitalization, characterized by digital testing processes (report traceability) and one-stop compliance services.
For purchasers, the recommended approach is to ensure standard alignment, comprehensive testing, and report verification.
Getting EN testing right paves the way for smooth access to the EU market.
