17、EN ISO 24346:2012ISO 24346:2006(E)iv ISO 2006 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical c

18、ommittees. Each member body interested in a subject for which a tec hnical committee has beenestablished 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 closelywith th

19、e 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 committees is to prepare International Standards. Draft Internatio

20、nal Standardsadopted 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 possibility that some of the elements of this document may be th

22、s Determination of overall thickness1 Scope This International Standard specifies a method for determining the overall thickness of resilient floor coverings.2 Terms and definitions For the purposes of this document, the following terms and definitions apply.2.1 overall thickness vertical distance b

23、etween two parallel plates where a resilient floor covering is inserted under a specified load3 Principle The test piece is placed between two parallel plates, and the distance between them is measured, the contactpressure being adapted to suit the structure of the test piece.4 Apparatus 4.1Movable

24、circular upper plate . For various types of resilient floor covering structures, the diameter of the upper plate, the applied mass, thearea and the pressure shall be in accordance with Table 1. 4.2 Fixed lower plate , at least equal to size of the upper plate and at least 15 cm 2 . 4.3 Dialgauge, to

25、 measure the distance between the plates to an accuracy of 0,01 mm.4.4 Weighted ring or horseshoe (500 g), to hold the perimeter of the specimen uniformly flat against thefixed lower plate. 5 Sampling and selection of specimens 5.1 Sheet materialTake two representative samples from a roll, one frome

26、ach end, or from the beginning of two rolls. From each sample, cut a testpiece a minimum of 100 mm across the full width of the sample (see Figure 1).

27、ve tiles from carton as test pieces and cut them to the appropriate size of 50 mm 100 mm. Where a pack or carton of tiles comprises the sample, ensure that the first and last tiles are not used as test pieces. 6 Atmosphere for conditioning and testing Condition the specimens for a minimum of 24 h at

28、 (23C 2) C and relative humidity of (50 5) % and testin the same environment. 7 Test procedure 7.1 Preparation 7.1.1 Make sure the test instrument is level.7.1.2 Select the appropriate upper plate and force applied according to Table 1 for the test specimen type to be measured. Check that the presse

29、r foot and plates are clean. 7.1.3 Set the dial gauge to zero by allowing the presser foot to rest on the lower plate (anvil).

Place

32、the weighted ring or horseshoe centred to the presser foot (see Figure 2). Lower the presser foot gently until it contacts the surface of the specimen. When measuring materials with a foam layer, selectan unembossed f lat area that is substantially larger, if possible, than the presser foot and at l

33、east 20 mm from any edge of the specimen. Raise the presser foot andinsert the test specimen. 7.3.2 Read the thickness 5 s after application of loaded plate; read to the nearest 0,001 mm or to the measuring limits of the instrument being used. Make all measurements at least 20 mmfrom any edge of the

34、specimen. 7.3.3 Unless otherwise specified, make a total of five measurements on each sample at randomly selectedlocations. 7.3.4 Record the measured values for each test specimen to the nearest 0,01 mm.
