gabo Systemtechnik Laying instructions 10 speed•pipe® indoor Network level 4 Laying instructions. 3.1 Installation according to DIN VDE 0100520:2013-06 / IEC 60364-5-52:2009-10. All dimensions of speed•pipe® indoor were tested in the VDE test institute according to DIN EN 61386-22. Here, the mechanical strength values are taken from the table F.52.1 under point 521.6 (DIN VDE 0100-520), which the electrical installation pipes (speed•pipe® indoor) must correspond to. Essentially are the first four digits of the code, which reflect the following values by means of defined tests: • Compressive strength of the electrical installation pipes • Impact strength of the electrical installation pipes • Minimum operating temperature of the electrical installation pipes (Classification code 2 -5 °C) • Maximum operating temperature of the electrical installation pipes (Classification code 2 +90 °C) Further tests of the electrical installation pipes: Further tests of the electrical installation pipes (speed•pipe® indoor) are, for example, the resistance to bending, the tensile strength, the load capacity, the electrical properties, resistance to external influences and resistance to flame spread. The mechanical strengths are classified from positions 1 – 4 (5), whereby 1 is the lowest classification – for example “very low” – and 4 (5) is the highest classification – for example „very high“.
