CATEGORY II ITEM 6 - PRODUCTION OF STRUCTURAL COMPOSITES, PYROLYTIC DEPOSITION AND DENSIFICATION, AND STRUCTURAL MATERIALS

S/2012/947

Note: The only resin impregnated fibre prepregs specified in 6.C.1. are those using resins with a glass transition temperature (Tg), after cure, exceeding 145 o C as determined by ASTM D4065 or national equivalents. Technical Notes: 1. In Item 6.C.1. ‘specific tensile strength’ is the ultimate tensile strength in N/m 2 divided by the specific weight in N/m 3 , measured at a temperature of (296 ± 2)K ((23 ± 2)°C) and a relative humidity of (50 ± 5)%. 2. In Item 6.C.1. ‘specific modulus’ is the Young’s modulus in N/m 2 divided by the specific weight in N/m 3 , measured at a temperature of (296 ± 2)K ((23 ± 2)°C) and a relative humidity of (50 ± 5)%.
