1. Cross-sectional area of dumbbell-shaped test piece = thickness (cm) × width of parallel part (cm)
2. Tensile strength TB (Kg/cm2) = breaking load (kg) F B/section area of test piece ( c㎡ ) A
3. Elongation EB( %) = ( distance of punctuation point at break L1-distance of original punctuation point L0 )/ distance of original punctuation point L0 x 100%
4. Adhesive strength TF (Kg/c㎡) = peeling load (kg) F F/test piece width (cm) b
5. Tear strength TS (Kg/cm2) = maximum load (kg) FS/test piece thickness (cm) t
6. Tensile stress M M (Kg/cm 2 ) = load at specific elongation (kg) Fn/cross-sectional area of test piece (cm 2 ) A
(The n of Mn here means the specific elongation (%), for example, M300 means the tensile stress when the elongation is 300%).
