The work of preparing International Standards is normally carried out through ISO technical committees. Each member bod
13、y interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrote
14、chnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by t
15、he technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights

ISO shall not be held responsible for identifying any or all such patent rights.ISO 6356 was prepared by Technical Committee ISO/TC 219, Floor coverings.This second edition cancels and replaces the first edition (ISO 6356:2000), which has been technically revised.iv ISO 2012 All rights reservedBS
17、ISO 6356:2012ISO 6356:2012(E)IntroductionThis test is a measurement of the electric potential (voltage) due to the accumulation of static charge on a person walking on the surface of a textile and laminate floor covering under controlled conditions. It is important that this measurement is made unde
18、r carefully controlled conditions to minimize test variability. ISO 2012 All rights reserved vBS ISO 6356:2012BS ISO 6356:2012Textile and laminate floor coverings Assessment of static electrical propensity Walking test1 ScopeThis International Standard specifies a method of evaluating the electrosta
19、tic propensity of textile and laminate floor coverings under controlled conditions. Since the potential generated varies with humidity, shoe materials, walk surface and individuals mannerisms, the values generated by this test will not necessarily reflect actual field experience, but will provide a
20、relative comparison of the performance of different surfaces.For classification purposes and in cases of dispute, the measurement procedure specified in this International Standard can be used under controlled conditions specified in the relevant classification standard or agreed between disputing p
21、arties. There may be occasions where measurements are required under non-controlled conditions, e.g. in situ measurements on installed floor coverings. The principle of measurement using the equipment specified in this International Standard can be used to make measurements, either with the standard
22、 footwear specified or with specific footwear relevant to the end use.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

38、 input resistance of voltmeter and hand electrode system: 1013; input capacitance of hand electrode: 20 pF; response time: 0,25 s; capable of measurements from -20 kV to +20 kV.5.9 Measuring devices for temperature and relative humidityMeasuring devices should meet the following requirements: resolu

40、for textile floor coverings in accordance with ISO 1957. From each sample, select a specimen measuring 2 000 mm 1 000 mm in the machine production direction.Generally, the test is performed on the floor covering as received, i.e. with finishes and special treatments as appropriate. If the permanency
41、 of such finishes and treatments is being investigated, the specimen may be submitted to a cleaning process or to practical wear conditions before testing.6.2 LaminateCarry out sampling and selection of specimens for laminate, trying to cover an area measuring 2 000 mm 1 000 mm.7 Preconditioning of
42、specimens, PE-foam, PE-foil and rubber matsPre-condition the test specimen for at least 24 h in an atmosphere of (23 3) C and (55 10) % relative humidity.If possible, ensure free air circulation by, for example, placing samples on a rack or suspending them.The rubber mat (5.2), PE-foam (5.3), PE-foi
43、l (5.4) and sandals (5.5) shall not be used for any other purpose and should be permanently maintained in the test atmosphere. If this is not possible, the rubber mat, PE-foam, PE-foil and sandals shall be conditioned for 2 d prior to testing.Care should be taken to ensure specimens and equipment ar
44、e adequately conditioned, particularly where certain finishes can lead to slow conditioning. ISO 2012 All rights reserved 3BS ISO 6356:2012ISO 6356:2012(E)8 Atmosphere for conditioning and testingCondition the test piece at a temperature of (23 2) C and relative humidity of (25 2) % for a minimum of
45、 7 d, and maintain these conditions during testing. When the test is carried out in situ, record the ambient temperature and relative humidity.NOTE Several standard atmospheres are specified by various regional authorities based upon the severity of conditions the floor covering normally experiences
46、 in service. Values determined under one set of conditions cannot be compared to those using another set of test conditions.9 Test procedures9.1 Preparation9.1.1 Cleaning the sandals9.1.1.1 BAM sandalsBefore beginning a test series, scrub the BAM sole material using a piece of scoured cotton (5.6.2)
47、 wetted with ethanol or isopropanol (5.6.3) to remove any chemical substance from the surface. Repeat the cleaning procedure with demineralized water (5.6.4) until no dark marks appear on the cloth. Repeat the ethanol/isopropanol and water cleaning procedure prior to testing each specimen.Wait at le
48、ast 5 min and make sure the soles are completely dry before testing.If the sole material becomes severely contaminated, it may be necessary to use more rigorous cleaning procedures prior to commencing a test series. Especially in the case of the BAM-soles, it is recommended to abrade the dry soles w
49、ith a fine sandpaper (5.6.1) and then remove the dust. It is generally recommended to clean the sandals before each test series and before storing the soles at the end of the day.9.1.1.2 Neolite sandalsBefore beginning a test series, scrub the Neolite sole material using a piece of scoured cotton (5.6.2) wetted with ethanol or isopropanol (5.6.3) to remove any chemical substance from the surface. Wait at least 5 min and make sure the soles are completely dry bef
