BS EN ISO 9163:2005

This standard BS EN ISO 9163:2005 Textile glass. Rovings. Manufacture of test specimens and determination of tensile strength of impregnated rovings is classified in these ICS categories:

• 59.100.10 Textile glass materials

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 linear densities, but the short method is described for 1 200 tex rovings only, which is the linear density that allows the fibres in the roving to spread out most easily during impregnation.
