The product shall be formed as a number of ends@ tows@ or strands collected into a parallel bundle with little or no twist. Classification: Organic fiber 15@000 denier (16@700 dtex) roving with 21.0 gpd (185.3 cN/tex) nominal tensile strength and 600 gpd (5295 cN/tex) nominal tensile modulus for use in cables and cordage requiring high tensile strength and moderate modulus of elasticity in tension. This shall be a 10 end roving.
