Source: Measured (test report) · Fire resistance: EI 180 to EN 1366-2 / ISO 21925-1 (specimen 600 × 600 × 400 with Hoocon HVD230S-5P and enclosure, laboratory in Guangzhou, 2026; per Starduct leaflet, report shown to customers directly). Open pressure drop: Starduct internal measurement on FS samples 180 × 180 and 600 × 600 (AMCA 500-D-18 set-up, not third-party). Closed leakage: internal measurement on FSS-L210 samples 180 × 180 and 600 × 600 (same single-blade construction, cross-geometry).
