Method of
work:

Yarns are subject to tensile force to break. The measuring length of the tube is 50 mm, pre-load is 0.5 cN. After testing the average value of measurement results is calculated.

Department,
room, location:

Department for Textile Chemistry and Ecology, Textile Research Laboratory, Savska cesta 16/9

Addition note:  

The corresponding standards:

ISO 2062:1993 – Textiles – Yarn from packages – Determination of single-end breaking force and elongation at break

ISO 6939:1988 – Textiles – Yarn from packages – Method of testing for breaking strenght of yarn by skein method
