WebEarth materials must be classified consistently to establish correlation and stratigraphy of the site and to develop the design of the structure and construction methods to fit the site conditions. This chapter out- lines some of the more important properties of earth materials and their description and classification. WebOct 17, 2016 · Based on the recent amendments to BS EN 50522 and IEEE Std.81, Step and Touch voltage safety has become the driving criterion for safe Earthing/Grounding Design. It used to be the 1-ohm earth mat that would ensure safety, but this is no longer the case. Current wisdom and best practices adopted by both the IEEE and IEC bodies.
