39、N 62561-7:2012 8 62561-7 IEC:2011 3.3 leaching test test during which the earthing enhancing compound is put into contact with a leachant and some constituents of the material are extracted 4 Requirements 4.1 General Earthing enhancing compounds shall be so designed and constructed that in normal us
40、e 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. 4.2 Documentation The manufacturer or supplier of the earthing enhancing compounds shall provide adequate information i
41、n his literature to ensure that the installer can select and install the materials in a suitable and safe manner. Compliance is checked by inspection. NOTE The manufacturer in his literature should provide information regarding the maintenance followed by the user over time in order for the characte
42、ristics of the earthing enhancing compound to remain stable. 4.3 Material The material of the earthing enhancing compound shall be chemically inert to subsoil. It shall not pollute the environment. It shall provide a stable environment in terms of physical and chemical properties and exhibit low res
43、istivity. The earthing enhancing compound shall not be corrosive to the earth electrodes being used. Compliance is checked by the tests specified in 5.2, 5.3, 5.4 and 5.5. 4.4 Marking All products complying with this standard shall be marked at least with the following: a) manufacturers or responsib
44、le vendors name or trade mark; b) identifying symbol; c) resistivity. The marking should be given on the packing unit. Compliance is checked in accordance with 5.6. 5 Tests 5.1 General The tests in accordance with this standard are type tests. Unless otherwise specified, tests are carried out with t
45、he specimens prepared as in normal use according to the manufacturers or suppliers instructions. All tests are carried out on new specimens. BS EN 62561-7:201262561-7 IEC:2011 9 NOTE Unless otherwise specified, three samples are subjected to each individual test and the requirements are satisfied if
46、 all the criteria are met. The applicant, when submitting the material to be tested, may also submit an additional quantity which may be necessary should one test fail. The testing station will then, without further request, repeat the test and will reject only if a further failure occurs. If the ad
47、ditional sample is not submitted at the same time, the failure of one test will entail rejection. 5.2 Leaching test 5.2.1 General The leaching test shall be performed according to EN 12457-2: Fe (iron); Cu (copper); Zn (zinc); Ni (nickel); Cd (cadmium); Co (cobalt); Pb (lead). 5.2.2 Determination of
48、 leachable ions Determination of the concentrations of constituents of interest shall be performed according to EN 12506. 5.2.3 Passing criteria The criteria are given by national or international regulations. 5.3 Sulphur determination 5.3.1 General A test for the determination of sulphur shall be p
49、erformed according to ISO 4689-3 or ISO 14869-1 and the adapted analyses instrumentation (ICP-OES, ICP-AES or other ICP methods). 5.3.2 Passing criteria The material is deemed to have passed the test if all measured values are less than 2 %. The recorded value resulting from this test shall be indicated within the product documentation. 5.4 Determination of resistivity 5.4.1 General The fourelectrode method is used to measure the resistivity of earthing enhancing compounds as descr
