This International Standard specifies a method for the determination of the tensile breaking force and breaking elongation of glass yarns taken from packages. This method is applicable to various types of glass yarn (single, folded, cabled, strands, structurer without twist, rovings, etc.). It is basically intended for single, folded and cabled glass yarns having a diameter of less than 2 mm, or a linear density lower than 2000 tex taken from packages. However, for yarns having a diameter greater than 2 mm or a linear density exceeding 2 000 tex, and for other types of textile glass yarn, the method can be applied with the reservation that the conditions are acceptable to all parties concerned with the test results. The method is not applicable to glass yarns which, in equilibrium with the standard atmosphere and under a pretension of 5 mN/tex, are elongated by more than 0,5%. Such yarns can be tested using a lower pre-tension (for example 2,5 mN/tex or 1 mN/tex) acceptable to all parties concerned with the test results. This would occur mainly when dealing with staple fibre yarns.
