3 Definitions
For the purposes of this document, the following terms and definitions apply.
3.1
earthing enhancing compound
compound improving the contact surface of the earth electrode without damaging the electrodes or
polluting the environment
3.2
manufacturer’s, supplier’s instructions
written instructions provided by the manufacturer or the supplier in his documentation (see 4.1)
3.3
leaching test
test during which is put into contact with a leachant and some constituents of the material are
extracted
4 Requirements
Earthing enhancing compounds shall be so designed and constructed that in normal use their
performance is reliable and without danger to persons and the surrounding.
The choice of a material depends on its ability to match the particular application requirements.

4.1 Documentation
The manufacturer or supplier of the earthing enhancing compounds shall provide adequate
information in his literature to ensure that the installer can select and install the materials in a suitable
and safe manner.
Compliance is checked by inspection.
4.2 Material
The material of the earthing enhancing compound must exhibit low specific resistance and chemically
inert to subsoil. It must not pollute the environment. It must be insoluble in water. Its aquatic
suspension must not exhibit an acidic pH. It must not contain substances corrosive to the earth
electrodes. It must be inert to steel, stainless steel, zinc, copper.
4.3 Marking
All products complying with this standard shall be marked at least with the following:
a) manufacturer's or responsible vendor's name or trade mark,
b) identifying symbol.
Where this proves to be impractical the marking in accordance with b) may be given on the smallest
packing unit.
NOTE Marking may be applied for example by moulding, pressing, engraving, printing adhesive labels, or water slide transfers.
Compliance is checked in accordance with 5.7.
5 Tests
5.1 General
The tests in accordance with this standard are type tests.
– Unless otherwise specified, tests are carried out with the specimens prepared as in normal use
according to the manufacturer's or supplier's instructions.
– All tests are carried out on new specimens.
– Unless otherwise specified, three samples are subjected to the tests and the requirements are
satisfied if all the tests are met. If only one of the test does not meet the passing criteria , that test
and any preceding one which may have influenced the results of the test shall be repeat
