This International Standard specifies two methods for the determination of the tensile stress at break of an impregnated roving:
The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the reference method may be used for various linear densities, but the short method is described for 1200 tex rovings only, which is the linear density that allows the fibres in the roving to spread out most easily during impregnation.
