Sample The outer diameter of the deformation amount after flattening should be from 25% to 50% of the initial diameter. If the outer diameter of the sample is crushed after the initial diameter of less than 25%, you should perform the following additional tests. Force uniform steel block pressed against the test Thus, until the (30 ± 3) s after the outer diameter of the sample was crushed after the initial diameter (30 ± 3)%, measured force. A new sample is subjected to a uniform increase in pressure (the N), within (30 ± 3) s, the force reaches the value of the force measured above. The sample is crushed Outer diameter after deformation should be 25% to 50% of the initial diameter. Pressure should then be removed and force the steel block. In removed pressure 15min, again measured in the sample is flattened at the outer diameter. After the test, the difference between the outer diameter of the sample was crushed after the initial diameter and should not exceed 10% of the outer diameter measured before the test, and the sample will not be permitted Now without additional amplification normal or corrected vision visible cracks. 10.4 Bending test Alternative. 10.4.101 conduit bending test should be carried out, the test apparatus 101 shown in FIG. 10.4.102 test shall be performed on the catheter 6 samples. The length of each sample shall be at least. a) to the flat conduit, the nominal length of 30 times the outer diameter; b) For the corrugated conduit and a length of 12 times the nominal outside diameter. Minimum temperature remaining three should be based on a declaration form transport, use and installation; 3 samples shall be carried out at ambient temperature test Test, the deviation shall be ± 2 ℃. 10.4.103 For the test, the sample should be carried out at ambient temperature in a vertical clamping device 101 shown in the bending test. Slow hand The sample was slowly bend to the left (90 ± 5) Returns the vertical position after °. Then bent to the right samples (90 ± 5) Returns the vertical position after °. Exercise Should be repeated for the number of repetitions should be more than three times after the test specimen shall not return to the vertical position. The specimen should be kept in bent position 5min, The specimen is then bent to be tested is placed in the following way. straight portion and a plumb line (45 ± 5) °, one end of the sample up, and the other end Down. For according to Table 1 Statement of transport, use, test the minimum temperature of the installation carried out, the sample should be clamped as shown in FIG. 101 in Bend Song on the test apparatus and a temperature above freezing box by pretreatment 2h, temperature deviation of ± 2 ℃. After the test, the specimen shall not appear in the absence of additional amplification normal or corrected vision visible cracks, and the test should enable compliance with Figure 102 Corresponding gauge is shown in its initial speed of the case does not have any of its own weight through the catheter. 10.5 bending test GB/T 20041.1-2005 this section does not apply. 10.6-destructive testing GB/T 20041.1-2005 this section does not apply.

Catheter samples and terminating conduit fittings shall be in accordance with the manufacturer's instructions and as shown in FIG. 103 are assembled fixed. To the ends of the transmission assembly The 25A, as shown in 50Hz ~ 60Hz frequency alternating current (no-load voltage of the power supply does not exceed 12V) 1min + 5 0s after 103 in FIG. Measuring the ratio of the voltage drop across the assembly, the resulting voltage drop and current is resistor. Resistance not exceeding 0.05Ω. If you use special devices to connect conduit and conduit fittings, these devices should be sufficient to fully remove the protective coating of the catheter, or shall be made The manufacturer's prescribed protective layer removed. 12 Thermal Performance GB/T 20041.1-2005 after this chapter apply for the following modifications. 12.3 Replacement. Then, load removed, the sample was immediately placed in the vertical direction, so that in line with the corresponding gauge shown in FIG. 102 is not any one of its own weight The case where the initial velocity through the conduit, should be able to gauge catheter. 13 flame effect GB/T 20041.1-2005 this chapter apply. 14 external influences GB/T 20041.1-2005 this chapter apply. 15 Electromagnetic Compatibility GB/T 20041.1-2005 this chapter apply.
