TESTING
Hydrostatic Test Filled with water and internal pressure incured to 220±7psi,
at a temperature of 68°FH±5°FH for a period of 5 mimutes.
Bending Test At 68°FH filled with water and the internal pressure increased to 588±7psi, 
at a temperature of 68°FH5°FH for a period of 5 minutes.
Hydrostatic Burst Test Bending motion being applied uniformly at the rate of 5-6 cycles per minute
Hydrostatic Shock Test Subjiectd to a hydraulic shock for 2,000 cycles at 68°FH±5°FH
Vibration Test  Filled with water.
The amplitude of vibration was 0.2 inches and the frequency was 25Hz for 3 hours
Flattening Test  Pressed to 2/3 D height of the outer diameter until the tube was flat
Impact Test  An impact force was applied of 9.76 to 15.19 Ib/ft to varied sizes of fittings using a hammer
Pressure Test Pressure rating at 212°F of 147 psi
Toxicity water outflow was tested in hot and cold conditions with a PH range of 5-10
