Scope: This covers the recovery of wide or narrow elastic in loop form after stretching for 500 cycles

Apparatus:
CRE-Constant-Rate of Extension Machine-Instron Band Clamps- to hold loop specimen
Sewing Machine Markers Rulers

Conditioning:
Before making any tests for loop tension condition the samples in a 70 degrees F 65% Relative Humidity for 4 hrs.

Preparation of Test Specimen: (Base on ASTM D 4964)
Cut specimen with 14 inches dimensional parallel to the length Draw two gage marks on the specimen:
1. Which are10 inches apart
2. Approximately the same distance from the specimen ends.
3. Parallel to one another
4. Perpendicular to the long direction of the test specimen. see below photo:
