Survey Preparations: 1. Reviewed certificates of calibration for all applicable measurement instruments used during the

preparation of the samples and for monitoring the tests.

2. Verified that all samples were identified and meet the proposed dimensional requirements.

3. Verified the assembly configuration for each proposed test:

a) Enery Release Rate (Gamma Testing)

b) Short Term Spool Test

c) 1000 Hour Lap-Shear (300 degrees farenheit)

d) Impact Test

e) Heat Distortion Temperature (HDT)
