Inspection Date Feb, 14th 2014

Testing Item Nylon Hose (PA12 hose)

Testing Quantity 10 PCS sample

Samples: 1 m hose

Testing Items Dimensions(mm) Burst Pressure(Mpa) Temperature Resistance(℃)

12*9 12±0.15 9±0.1 1.5±0.1 6.29 -40 ~+110

Surface Checking surface is smooth，no air bubble，no crack,the color is well distributed

Testing Result Conforms to standard

Appearance checking

Diameter: After setting an outer diameter of 12mm，no tolerance if display as 0 and otherwise not meet the standard if figure larger than0.15mm.

Thickness: measure directly

Tensile Testing

Burst Testing

Set the pressure to 1614N and start the machine. If the pipe doesn't break, then it does meet the standard, otherwise, doesn't meet the standard.

Burst Testing

Burst test: Fix the pipe to the test machine and increase the pressure inside the tubes. Don't record the pressure until the pipe burst. It is failature if the figure is lower than 5.4.
