21、e generated by a person walking on the floor covering 3.2 earthed connected to a reference earth (part of the Earth considered 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 walk
22、ing test with an operator using a pair of standard sandals, walking over the floor covering situated over a earthed metal base 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

27、st sandals shall be open sandals of European size 42 without heels and with straps mounted to fit various foot sizes. A rubber sole material shall be used. The resistance between the metal plate and the person standing on it wearing the sandals with the soles shall be (108to 109) . NOTE 1 For guidan
28、ce on the possible effect of the operators clothing and other factors on test results, see informative Annex A.

31、ll be used for discharging the test piece and the PE foam. 5.6 Body voltage measuring system The body voltage measuring system (see Figure 2) consists of a DC static voltmeter, an autographic recorder and a hand electrode (see Figure 3) and shall meet the following requirements: input resistance of
32、voltmeter and hand electrode system: 1013 ; input capacitance of hand electrode: 20 pF; response time: 0,25 s; capable of measurements between (20 to + 20) kV.

34、a calibrated wet and dry bulb thermometer (psychrometer) with a scale reading to 0,1 C. 6 Conditioning Condition 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
35、during testing. When the test is carried out in situ, the ambient temperature and relative humidity shall be 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 su
36、rface, use the abrasive paper and clean again with a clean piece of cloth and ethanol or isopropanol. Wait at least 5 min and make sure that the soles are completely dry before testing. BS EN 1815:2016EN 1815:2016 (E) 8 7.2 Method A: test procedure in laboratory conditions 7.2.1 Preparation Place th
37、e required earthed metal plate, PE-foil/PE-foam (for laminate floor covering) on the floor in the conditioned 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 approximat
38、ely 20 mm over the PE-foam and the test piece to eliminate any residual static charge. 7.2.3 Walking test 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 fr
39、om zero voltage. With the hand electrode in the hand, walk on the test piece with regular paces at a rate 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
40、mm above the test piece. Lift and lower the sandal sole in a plane parallel to the test piece. Cover as 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 thre
41、e times. 7.3 Method B: test procedure in situ Record the ambient temperature and relative humidity, and 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 tes
42、t as in 7.2.3. 8 Calculation and expression of results The “walking” test will give a voltage diagram as 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 kilo
43、volts, to the nearest 0,1 kV by using the absolute value of the calculated average. Calculate the average of the three test results to the nearest 0,1 kV.

The voltage peak will therefore depend on the distance between the lifted foot and the floor surface. Figure 4 Typical voltage d

47、 information: a) a reference to this standard and the method used, i.e. EN 1815, method A or B; b) a complete identification of the product tested, including colour and manufacturers reference number.

49、10 Precision The test results of static electrical charge generated by a person walking on a floor are affected by the inhomogeneity of the floor covering and can very much depend on the relative humidity. Factors which may affect repeatability and reproducibility are described in informative Annex A.
