WebDec 19, 2024 · The flame-retardancy of composites was studied by the limiting oxygen index (LOI) and UL-94 test. The LOI values of EP–DSD composites increased from 30.7% for a content of 3 wt % to 35.4% for a content of 9 wt %. When the content of DSD reached 6 wt %, a V-0 rating under the UL-94 vertical test was achieved. WebUL 94 Flammability Ratings. Plastic Enclosures are rated for flammability using the UL 94 standard. There are 6 levels of certification that can be obtained as follows: -. 5VA (Surface Burn) - Burning stops within 60 seconds after 5 applications of 5 seconds each of a flame (larger than used in vertical burn testing) to a test bar.
