Static Shear - ASTM D3654 - To stainless steel, tested at various temperatures and gram loadings. 0.5 in 2 (3.22 cm 2 ). Will hold listed weight
for 10,000 minutes (approximately 7 days). Conversion: 1500 g/0.5 in 2 equals 6.6 lb/in 2 ; 500 g/0.5 in 2 = 2.2 lb/in 2 .
Short Term Temperature Tolerance - No change in room temperature dynamic shear properties following 4 hours conditioning at indicated
temperature with 100 g/static load. (Represents minutes, hours in a process type temperature exposure).
Long Term Temperature Tolerance - Maximum temperature where tape supports at least 250 g load per 0.5 in 2 in static shear for 10,000
minutes. (Represents continuous exposure for days or weeks).
