The 2013 edition is the most mature version of the standard, superseding the 2000 edition. Key updates include:

To ensure your engineering calculations are legally compliant and technically accurate, use official channels:
: Always verify the fault clearing times and other site-specific data with the utility's protection engineers. Your grounding system design is only as accurate as the fault current and clearing time data you use.
To ensure your engineering project aligns with the latest compliance parameters, let me know: = Resistivity of the surface material (e

). If the GPR is lower than the tolerable touch voltage, the design is safe. If higher, you must perform detailed mesh and step voltage calculations.
You calculate the grid resistance (Rg) using the updated Schwarz or Laurent-Niemann formula from Clause 14. Then multiply by the grid current (Ig). If GPR exceeds the tolerable touch voltage, the design fails. Official copies are protected by copyright and typically
