TENSILE STRENGTH TESTING PROCEDURE

Step: 1- Precaution /Condition Taking before testing

     

       All Receiving samples are required minimum 4 hours condition with temperature @ 20±2 °C & humidity 65±2 °C

Step: 2- Cut sample systematically in both direction like Warp & Weft in Left, Middle, Right position with proper reveling

Step:3-Mark the parallel line  of 38 mm with warp and weft direction for finding of middle position of the specimen

Step: 4- Testing procedure with different methods.

Test Methods	Sample Size	Gauze Length	Jaw Size	M/C Speed
ASTM D5034 (Grab Method)	150x100mm	75 mm	25x50	300 mm/Min.
ISO 13934-1 (Stripe Method)	300x50 mm	200 mm	75x75	100mm/ Min.
ISO 13934-2 (Grab Method)	180x100mm	100 mm	25x50	50 mm/min.
M&S P11 (Stripe Method)	250x50 mm	200 mm	75x75	300 mm/Min.

Step: 5- Then taken 3 different reading with Tenuous Olsen Tensile Strength Testing Machine.

Step: 6-For the acceptance of result the test specimen should be brocken with minimum 0.5mm distance from the jaw grip. Other wise result is discarded.

Step: 7- Give Average result of 3 different Reading and pass/ fail according to the customer          standard protocol requirement.s
