Place grommets on specimen. 4. Measure the distance between the grommets (in-line), using precision sliding caliper. This

13、results in 6 measurements (3 in MD and 3 in AMD). 5. Place specimen in oven (pre-heated to 200C), for 2 minutes. 6. Remove specimen from oven and let cool down and acclimate for at least 1hour. 7. Measure again the same distances, with the same caliper, and calculate the difference. 8. Calculate Shr
