After four drop tests from a height of 1 meter, no damage caused by the test shall impair the explosion-proof performance of the electrical equipment. ▲14. The flameproof performance meets the test requirements of IIC electrical equipment: No explosive transmission occurs after 5 internal ignition tests with 7.5% C₂H₂ gas; no explosive transmission occurs after 5 internal ignition tests with 27.5% H₂ gas. ▲15. A test voltage of 1500V is applied between non-intrinsic safety terminals and intrinsic safety terminals for no less than 1 minute without dielectric breakdown. A test voltage of 500V is applied between non-intrinsic safety terminals and enclosure, as well as between intrinsic safety terminals and enclosure for no less than 1 minute, with no dielectric breakdown. ▲16. Sealing rings and adhesive seals: No obvious deterioration after 672 hours storage at 95 °C and 90% relative humidity; no obvious deterioration after 24 hours storage at -25 °C. 17. Test reports marked with CMA or CNAS issued by nationally recognized third-party testing institutions shall be provided. All items marked with ▲ shall be covered in the test reports.
