Weight ASTM D 3776 option C Weight in ounces per square yard 1.7 oz/sq. yd 1.378 oz/sq. yd
Thickness ASTM D1777 Measures the thickness of the fabric from the inside surface to the outside surface. .054 inches .007 inches
Tensile Strength – Strip Method ASTM D 5035 Determines the breaking force required to tear a strip of fabric by grabbing and pulling in each direction. Length 6.75 lbs

Width 8.86 lbs		 Length 7.9 lbs

Width 7.1 lbs
longation % ASTM D 5035 Determines by percent the degree to witch a fabric will stretch before braking by grabbing and pulling in each direction. Length 62.45 %

Width 59.32 %		  
Tongue Tear ASTM D 2261 This test measures the capacity of a fabric to withstand the tearing force to propagate a single tear after its initiation. Origin of tear is initiated prior to testing. Results measure the force required to maintain a constant rate of tear in each direction after the initial tear. Length 5.85 lbs

Width 5.35 lbs		 Length 3.1 lbs

Width 3.3 lbs
Bursting Strength ASTM D 3786 Measures the force required, applied at right angles, at which point the fabric will burst 92.5 lbs 60 lbs
Water Resistance-

Suter Hydrostatic Pressure Tester, Option 1, 10 mm/sec.		 AATCC 127 Evaluate barrier effectiveness against liquids. Measure the 157.7 cm of water  
Air Permeability ASTM D 737 Measures the air permeability of the fabric. The rate of air flow is adjusted to obtain a prescribed air pressure differential between the to fabric surfaces. <.130 cubic feet  per min of air /sq. ft  
Moisture Vapor Transmission

(Test conditions were 73.4oF + 2oF and 50% RH + 2% RH)		 ASTM E 96, Method B Measures the time rate of water vapor transmission through a unit area of fabric. 453.6 (g/m2/24 hours) 580 (g/m2/24 hours)
Flamability CFR-1610 Class 1 means when time of flame spread is 4 seconds or more Class 1 Class 1
