24、ed as conductive, the electric potential of which is conventionally taken as zero) 4 Principle A floor covering is evaluated for static electrical propensity by means of a walking test with an operator using a pair of standard sandals, walking over the floor covering situated over a earthed metal ba
25、se plate (resilient floor coverings) or over a PE-foam/PE-foil situated over a grounded metal base plate (laminate floor coverings). 5 Apparatus 5.1 Substructure for resilient floor coverings A earthed metal base plate shall be used, e.g. a stainless steel plate of approximately (100 200) cm and 1 m

37、ion the test piece, the PE-foam, the PE-foil (5.2) and the sandals (5.3) at a temperature of (23 2) C and relative humidity of (25 2) % for a minimum of 7 days, and maintain these conditions during testing. When the test is carried out in situ, the ambient temperature and relative humidity shall be
38、recorded. 7 Test procedure 7.1 Cleaning of test sandals Before each test series and after each individual test, clean the soles with cotton cloth and ethanol or isopropanol. To roughen the surface, use the abrasive paper and clean again with a clean piece of cloth and ethanol or isopropanol. Wait at
39、 least 5 min and make sure that the soles are completely dry before testing. EN 1815:2016 (E) DIN EN 1815:2016-12 8 7.2 Method A: test procedure in laboratory conditions 7.2.1 Preparation Place the required earthed metal plate, PE-foil/PE-foam (for laminate floor covering) on the floor in the condit
40、ioned test room (see Clause 5). 7.2.2 Discharging Discharge the PE-foam, when used, and the test piece before each individual test, by moving the ionizing source once over a distance of approximately 20 mm over the PE-foam and the test piece to eliminate any residual static charge. 7.2.3 Walking tes
41、t Place the sandals on the test piece. Step into the sandals and fasten them. Take the hand electrode, already connected with the static measuring device, and earth the person in order to start from zero voltage. With the hand electrode in the hand, walk on the test piece with regular paces at a rat
42、e of two steps per second, forwards and backwards but always with the body facing the same direction. Avoid scuffing or pivoting. At each step, lift the sandals approximately between 50 mm and 80 mm above the test piece. Lift and lower the sandal sole in a plane parallel to the test piece. Cover as
43、much of the test piece as possible and continue walking until the peak voltage ceases to rise, but for not more than 60 s. Take off the sandals while still on the test piece. Perform the test three times. 7.3 Method B: test procedure in situ Record the ambient temperature and relative humidity, and
44、the condition of the floor covering and, if relevant, any treatment prior to testing (e.g. cleaning, washing etc.). Place the sandals on the area of floor covering to be tested and perform the test as in 7.2.3. 8 Calculation and expression of results The “walking” test will give a voltage diagram as
45、 shown in Figure 4 and Figure 5. Determine from the recorder diagram the average of the five highest valleys (Figure 4: T1 T5) or the lowest peaks (Figure 5: T1-T5) and express the results in kilovolts, to the nearest 0,1 kV by using the absolute value of the calculated average. Calculate the averag
46、e of the three test results to the nearest 0,1 kV.
