The work of preparing International St

13、andards is normally carried out through ISO technical committees. Each member body 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

14、 take part in the work. ISO collaborates closely with the International Electrotechnical 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 committee

15、s is to prepare International Standards. Draft International Standards adopted by the 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 possib

16、ility 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

17、(ISO 6356:2000), which has been technically revised. iv ISO 2012 All rights reservedBS ISO 6356:2012ISO 6356:2012(E) Introduction This 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

18、 covering under controlled conditions. It is important that this measurement is made under carefully controlled conditions to minimize test variability.

19、ng test 1 Scope This International Standard specifies a method of evaluating the electrostatic 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 gener

20、ated by this test will not necessarily reflect actual field experience, but will provide a 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 controlle

21、d conditions specified in the relevant classification standard or agreed between disputing parties. 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 specifi

22、ed in this International Standard can be used to make measurements, either with the standard footwear specified or with specific footwear relevant to the end use. 2 Normative references The following referenced documents are indispensable for the application of this document.

From each sample, select a specimen measuring 2 000 mm 1 000 mm in th

41、e 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 of such finishes and treatments is being investigated, the specimen may be submitted to a cleaning process or to practical w

42、ear conditions before testing. 6.2 Laminate Carry out sampling and selection of specimens for laminate, trying to cover an area measuring 2 000 mm 1 000 mm. 7 Preconditioning of specimens, PE-foam, PE-foil and rubber mats Pre-condition the test specimen for at least 24 h in an atmosphere of (23 3) C

43、 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-foil (5.4) and sandals (5.5) shall not be used for any other purpose and should be permanently maintained in the test atmo

44、sphere. 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 are adequately conditioned, particularly where certain finishes can lead to slow conditioning. ISO 2012 All rights reser

When the test is carried out in situ, record the ambient tempera

NOTE Several standard atmospheres are specified by various regional authorities based upon the severity of conditions the floor covering normally experiences in service. Values determined under one set of conditions cannot be compared to those using another set of test co

Repeat the clea

48、ning 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 least 5 min and make sure the soles are completely dry before testing. If the sole material becomes severely co

49、ntaminated, 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 with 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 sandals Before beginning a test series, scrub the Neolite sole
