Impact Test Apparatus for Conduit Cable Buried Underground

The LS-B64 Impact Test Apparatus for Conduit Cable Buried Underground is designed and manufactured in full accordance with the requirements of IEC/EN 61386-24 Clause 10.3 and Figure 101 (GB 20041.24 Clause Clause 10.3 and Figure 101). 

Sample preparation: Take 12 samples of conduits or conduit accessories with a length of (200±5) mm. The conduits are tested separately, and the accessories are tested after being assembled with the conduits. If necessary, the accessories can be trimmed (without affecting the results). Determine the mass of the heavy hammer including the head and the guide device.

Test conditions: The test device is placed on a solid plane, and the samples are pretreated in a (-5±1)℃ cold box for 2 hours. After being taken out, a V-shaped block is placed (see Figure 101). The time from taking out the cold box to the completion of the impact is ≤10 seconds.

Test operation: The heavy hammer impacts each sample once, and the energy value refers to Table 102; the accessories are tested at the weakest point (≥5mm from the entrance), and the conduit is tested at the center of the length.
