ile strength of 23.5 x 10 4 m or greater, except aramid fibrous or filamentary materials having 0.25% or more by weight of an ester based fibre surface modifier; (b) glass fibrous or filamentary materials having a specific modulus of 3.18 x 10 6 m or greater and a specific tensile strength of 7.62 x 10 4 m or greater; and (c) thermoset resin impregnated continuous yarns, rovings, tows or tapes with a width no greater than 15 mm (prepregs), made from carbon or glass fibrous or filamentary materials specified in paragraph (a) or (b). NOTE The resin forms the matrix of the composite. (d) composite structures in the form of tubes with an inside diameter of between 75 mm (3 in.) and 400 mm (16 in.) made with any of the fibrous or filamentary materials specified in paragraph (a) or carbon prepreg materials specified in paragraph (c). NOTE (a) fibrous or filamentary materials means continuous monofilaments, yarns, rovings, tows or tapes. (b) specific modulus is the Young’s modulus in N/m 2 divided by the specific weight in N/m 3 when measured at a temperature of 23 ± 2°C and a relative humidity of 50 ± 5%. (c) specific tensile strength is the ultimate tensile strength in N/m 2 divided by the specific weight in N/m 3 when measured at a temperature of 23 ± 2°C and a relative humidity of 50 ± 5%. B.1.1.10 Hafnium metal, alloys, compounds of hafnium containing more than 60% hafnium by weight, and their manufactures, and waste or scrap of any of these substances. B.1.1.11 Helium-3 or mixtures, products or devices containing helium-3, except a product or device containing less than 1 g of helium-3.

(b) porous nickel metal produced from materials referred to in paragraph (a), except single porous nickel metal sheets not exceeding 1 000 cm 2 per sheet. NOTE This refers to porous metal formed by compacting and sintering the material referred to in paragraph (a) to form a metal material with fine pores interconnected throughout the structure. B.1.1.16 Radium-226, radium-226 alloys, radium-226 compounds, or mixtures containing radium-226, products manufactured from them and products or devices containing any of them, except medical applicators and a product or device containing not more than 0.37 GBq of radium-226 in any form.
