Textile glass. Rovings. Manufacture of test specimens and determination of tensile strength of impregnated rovings Ingestion-build-190310 BS EN 4622 is a1 Scope This International Standard specifies two methods for the determination of the tensile stress at break of an impregnated roving: a reference method using test specimens produced with moulded epoxy tabs; a short method using test specimens with no tabs or simple cardboard or composite tabs. The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the reference method may be used for various
