(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. Rev.

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. Figure 1 Rev.

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 +/- 3C 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. Rev.

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.
