9 Construction

9.1 Surfaces of system components which are likely to come into contact with cables during installation are inspected to ensure they shall not cause damage to the cables when installed correctly.

9.2 As with all metallic system components, care should be exercised that handling is in accordance with the relative COSHH regulations and gloves should be worn.

9.3 Screwed connections have been designed to withstand the mechanical stresses occurring during installations and normal use and will not cause damage to cables when correctly inserted. Screwed connections are in general ISO metric threads fully compliant to tests in accordance with 9.3.1 and 9.3.2 of the standard. Metsec Cable Ladder Systems are usually assembled using M10 cup square bolts and hex nuts with lock washers for couplers etc tightened to a torque of 45N/m. Other connections require M10 hex bolts for clamps etc tightened to a torque of 25N/m.

10 Mechanical properties

Cable ladder lengths have been tested generally in accordance with the standard under 10.2 and 10.3 for verification of the loading graphs. It should be noted that independent testing has been carried out to verify the structural performance of the cable ladders at the minimum and maximum temperature classifications for test conditions under 10.2.2. All accessories eg bends, tees etc should be directly supported by a suitable support device or devices at appropriate positions.
