6. Test
6.1 Testing conditions
6.1.1 Environment
The tests shall be performed under ambient temperature and humidity (temperature 20 ± 5
C, humidity 65 ± 20%) specified in JIS Z 8703. (Standard Atmospheric Conditions for Testing)
unless otherwise specified.
6.2 Test Method
6.2.1 Appearance Test
6.2.2 Dimensions
1. Inside diameter
Prepare 5 tubes 50mm or longer. Select a smooth gage rod that will fit into one end of
the tube without causing the tube to expand. A gage rod that fits snug with no visible air
space between the end of the tube and the rod shall be measured and recorded as the
tubing inside diameter.
2. Thickness
Cut five tubes and a go-gauge for the inner diameter of the tubes. Insert the go-gauge
in each of the tubes and measure the outer diameter using a micrometer specified in JIS
B 7502 (Micrometer Calipers for external measurement) or other measuring instrument
having an equivalent or superior precision. The outer diameter shall be measured at
three points on each of the five tubes (15 total measurements). Half of the difference
between the measured outer diameter and the diameter of the go-gauge shall be
recognized as the thickness. The test result shall be represented by the average of the
15 measurements.
6.2.3 Cold Resistance Test
Cut a tube of adequate length and a flexible bar which has a diameter approximately
equal to the inner diameter of the tube. Insert the bar into the tube. Place the assembly
in a cold chamber at -40 +/- 3 C for 30 minutes. Remove the assembly from the cold
chamber and wrap it 180 over a mandrel specified in Table 3. For tubing that has an
inside diameter of 5mm or less wrap the tubing 6 turns around the mandrel in
approximately 6 seconds. Examine the tubes for evidence of cracks.

6.2.4 Tensile Strength and Elongation
1. Normal Temperature
a. Inside Diameter 8mm or less
Cut five tubes approximately 150 mm long. Mark the center of each piece with
50mm bench marks. Mount the test piece into a tensile testing machine specified in
JIS B 7721 (Tensile Testing Machines). Separation speed shall be approximately
200mm/min. Measure the load and the elongation between the bench marks when
the test piece is torn apart. Average the test results for the 5 test pieces for both
tensile strength and elongation. Any test pieces that break outside the bench marks
shall be excluded and another test piece prepared for the test. Temperature during
testing shall be recorded.
b. Inside Diameter greater than 8mm
Cut five tubes approximately 150 mm long. Slit each sample parallel to its
longitudinal axis and flatten so that it can be cut into a No. 4 dumbbell specified in
JIS K 6301 (Physical Testing Methods for Vulcanized Rubber) as shown in Figure 1
below. Mark the center of each piece with 20mm bench marks. Mount the test
piece into a tensile testing machine specified in JIS B 7721 (Tensile Testing
Machines). Separation speed shall be approximately 200mm/min. Measure the
load and the elongation between the bench marks when the test piece is torn apart.
Average the test results for the 5 test pieces for both tensile strength and
elongation. Any test pieces that break outside the bench marks shall be excluded
and another test piece prepared for the test. Temperature during testing shall be
recorded.
2. Residual Rate After Heating
Heat a 150mm long tube to a temperature of 180 +/- 5C for 200 hours. Remove
from heat and cool to room temperature. Measure the tensile strength and
elongation of the tube as described in 6.2.4 1.

6.2.5 Oil Resistance Test
Cut three tubes each approximately 150 mm long. Mix equal amounts of oil in which No.
1 lubrication oil of 1-3 types specified in JIS K2215 and the oil specified in JIS K 2209 or
equivalent are blended (See item 7). The mixed oil shall be heated to 50 +/- 3C prior to
testing. Soak the test pieces in the oil mixture for 20 hours. Remove the test pieces from
the oil mixture and lightly wipe the excess oil from the surface. Measure the tensile
strength and elongation of the tube as described in 6.2.4 1.
6.2.6 Flame Resistance Test
Cut a tube approximately 150 mm long. Insert a noncombustible rod into it and bend it
approximately 30 at a point 50mm from one of its ends. Hang it vertically by fixing the
other end so that it can be suspended over a flame of a spirit lamp or gas burner at a
point approximately 20 mm from its bottom end. When the test piece begins to burn
remove it from the flame and record the length of time the piece burns. During the test
provide a windshield to prevent the flame from being blown by a draft or breeze causing it
to flicker.
6.2.7 Heat Characteristic
1. Deformation After Heating
Prepare an arc-shaped test piece 30mm long and measure its thickness. Heat the test
piece to 120 +/- 3C for 30 minutes using a heat deformation tester specified in JIS C
3005 (Testing Methods for Rubber or Plastic Insulated Wires and Cables) item 23. Put
the test piece between the parallel plates of a measuring device shown in Figure 2 and
apply a load of 3.92N (400gf) to the test piece. Condition the assembly at 105 +/- 3C for
30 minutes, remove from heat and cool to room temperature. Remeasure the thickness.
The residual rate shall be calculated using the formula below.
Figure 2
2. Shrinkage After Heating
Cut 3 tubes approximately 300mm long as the test pieces. Put two benchmarks 200mm
apart in center of the test piece. Heat the test pieces to 120 +/- 3°C for one hour, remove
from heat and cool to room temperature. Measure the length between the two marks
using a pair of calipers specified in JIS B 7507 (Venir Calipers) or other measuring
instrument of equal or superior precision. Calculate the decrease rate by the formula
below. The test result shall be represented by an average of the decrease rate of the
three test pieces.

6.2.8 Heat Resistance
Cut a tube approximately 300mm long as the test piece. After heating the test piece at
200 +/- 30°C for 30 minutes, remove from heat and let it cool for 30 minutes or more at
room temperature. Wrap the test piece at least 3 turns around a mandrel that has a
diameter approximately equal to the outer diameter of the test piece. Examine the
condition of the test piece.
6.2.9 Volume Resistivity
Cut a tube of 250mm long as test piece. Select a well-polished metal bar which closely
fits inside of the tube. Insert the metal bar into the tube to serve as the inside electrode.
Wrap metal foil tightly around a 200mm wide section of the tube to serve as the outside
electrode. Apply voltage of 500V DC to the electrodes. Then measure the value of the
resistance using a highly sensitive absolute ohmmeter. The test result shall be calculated
as follows.
* = 1.257 x R/ln (d+2t/d)
*: volume resistivity (Q m)
R: measured volume resistance in ohms (Q)
d: diameter if inner electrode(mm)
t: thickness of test piece(mm)
6.2.10 Voltage Withstand Test
Cut a tubing specimen of adequate length and slit the specimen along one edge parallel to
its longitudinal axis. Place the test specimen between two electrodes as specified in JIS C
2110 Figure 5, item 7.1. The pressure applied to the specimen shall be approximately
4.9N (500gf). Increase the test voltage applied to the test specimen to 1000V at 50 or 60
Hz. The test specimen must withstand the test voltage for one minute.
6.2.11 Bridging
Cut a sample of tubing approximately 0.5g, weigh it and subject it to extraction for 18
hours using xylene with a Soxhlet extractor. Remove the sample and dry it at 100° C for 3
hours in a dryer. Remove sample from dryer and cool to room temperature. Reweigh the
sample. Calculate the weight difference as a percentage of the original weight.
