Hello guys , I am looking for the RATIO of backfill material for the Earthing electrode well & the reference.?

it would be a big help if you guid me to find a good reference standard (same: vde , din , jis ,... ) ?

Answer:
Whatever is in the local area would be OK, the electricians who put the earth rod in will just put more rod in if they need to to meet their requirements.

If you need specific things, look for a material that has a low electrical resistance (something the holds moisture well is a good one to use)
