1) The thickness of the coating in hot dipping or electrocoating is at least 1 μm.
2) Provided that the coating thickness is at least 50 μm, the coating should be smooth, continuous, and paste should be free of stains.
3) Applied for air termination rods only. Mechanical stresses such as wind load are critical for applications where there is no diameter 10 mm. Largest 1 m long and with additional fastening the air termination bar can be used.
4) Applies only to guide rods in the ground.
5) Chrome ≥ % 16, nickel ≥ % 8 andcarbon ≤ % 0,
6)For stainless steel that has direct contact with the material embedded in the concrete and/or flammable, small sizes up to 78 mm² (diameter 10 mm) for solid round types and up to 75mm² for solid strip typescan be increased (thickness at least 3 mm).
7)50 mm² (diameter 8 mm) in special applications where mechanical strength is not the basic rule
can be lowered up to 28 mm². In this case, attention should be paid to reduce the clearance between fasteners.
8)If thermal and mechanical considerations are important, these dimensions should be increased up to 60 mm² for solid strip types and up to 78 mm² for solid round types.
9)Smallest cross-section to prevent melting at a specific energy of 10 kJ/Ώ is16 mm² (copper), 25 mm²
(aluminum), 50 mm² (steel) and 50 mm² (stainless steel). It should be viewed to Annex E for more information.
10)Thickness, width, and diameter are defined as ± 10% tolerance.
