This European Standard shall be given the

17、status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This European Standard supersedes EN 986:1995. According to the CEN/CENELEC Internal Regulations,

18、 the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, P

19、oland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom. EN 986:2005 (E) 4 1 Scope This European Standard specifies a method for the determination of dimensional changes and distortion out of plane likely to take place when textile floor coverings in tile form are exposed

20、to various conditions of moisture and heat. This European Standard is applicable to all textile floor coverings in tile form. 2 Normative references The following referenced documents are indispensable for the application of this European Standard. For dated references, only the edition cited applie

21、s. For undated references, the latest edition of the referenced document (including any amendments) applies. EN ISO 139, Textiles Standard atmospheres for conditioning and testing (ISO 139:2005) 3 Principle 3.1 Dimensional stability Determination of changes in the flat dimensions of a specimen after

22、 treatment with various specified conditions of moisture and heat. 3.2 Distortion out of plane Measurement of the vertical deformation shown by the specimen after treatment with various specified conditions of moisture and heat. 4 Apparatus 4.1 Dimensional stability 4.1.1 Instrument capable of measu

23、ring a dimension to an accuracy of 0,05 mm, such as a slide gauge or measuring table or an opto-electronic system. 4.1.2 Loading plate of metal or glass of dimensions slightly smaller than the test specimen, or any other device capable of keeping the specimen flat during measurement of dimensional c

24、hange. 4.2 Distortion out of plane 4.2.1 Instrument capable of measuring in the vertical dimension to an accuracy of 0,5 mm. 4.2.2 Support plate of dimensions slightly larger than the test specimen on which to place the specimen during measurement. 4.3 Drying oven with forced ventilation able to mai

25、ntain a temperature of 60 C 2 C containing removable shelves of smooth inert material with perforations to permit free circulation of air. 4.4 Container to hold water at 20 C 2 C, of dimensions at least 20 mm greater than the test specimen and deep enough to permit the specimen to be submerged. EN 9

26、86:2005 (E) 5 5 Sampling and preparation of specimens 5.1 Tiles of dimensions 500 mm Take at least three tiles as delivered by the manufacturer, marking to show the direction of manufacture. 5.2 Tiles of dimensions 500 mm From these tiles take at least three specimens and reduce the size to dimensio

27、ns not greater than 500 mm x 500 mm. 6 Conditioning Condition the test specimens in the standard atmosphere for testing textiles as defined in EN ISO 139 for at least 48 h or until constant mass. 7 Test procedure 7.1 Initial measurements 7.1.1 Distortion out of plane Make all measurements on the con

28、ditioned specimen. Place each specimen with the use surface uppermost on the flat support (4.2.2). 7.1.2 Dimensional stability For the determination of the dimensional stability, it is important to measure the backing, the measuring system will determine whether the tiles should be positioned face u

29、pwards or downwards. Keeping the conditioned specimen flat with the loading plate (4.1.2), measure the distance between the sides parallel to the direction of manufacture then between the sides perpendicular to the direction of manufacture in at least two different places. Measure to the nearest 0,0

30、5 mm with the apparatus in 4.1.1. 7.2 Test procedure The same test specimen should be treated consecutively by all of the following procedures. 7.2.1 Place the test specimen in the oven at 60 C 2 C so that air can circulate freely around the specimen. After 2 h remove the specimen and perform the me

31、asurements in 7.1.2 at an interval of (5 1) min from the time of removal from the oven. 7.2.2 Immerse the test specimen flat in the water at 20 C 2 C. After 2 h remove the specimen taking care not to distort it (e.g. as a result of its weight). The excess of water is removed by use of blotting paper

32、, care has to be taken so as not to distort the sample. Perform the measurements in 7.1.2 at an interval of (5 1) min from the time of removal from the water. 7.2.3 Place each test specimen in the oven with the use surface uppermost at 60 C 2 C for 24 h then perform the measurements described in 7.1

33、.2 at an interval of (5 1) min from the time of removal from the oven. EN 986:2005 (E) 6 7.2.4 Re-condition the specimen in the standard atmosphere for testing textiles for 48 h or until constant mass. 7.2.5 After conditioning measure the distortion out of plane as follows: place each specimen with

34、the use surface uppermost on the flat support (4.2.2). Measure the vertical distance between the support plate and the back of the tile, measure this distance in each direction and in the position where it is greatest with the apparatus in 4.2.1, or at various places along each edge (edge curl). 7.2

35、.6 Then measure the dimensions of the specimen as indicated in 7.1.2. 8 Expression of results 8.1 Dimensional stability Calculate the dimensional change averaging (over the three specimens) for each direction and each stage of the procedure and express as a percentage by the following equation to th

36、e nearest 0,1 %: let lo, be the arithmetic mean of the initial measures; and lmithe arithmetic mean at each stage. Calculate the dimensional change and express as a percentage of the mean by the following equation percentage: (lm - lo) x 100 loIndicate the result with a - if it is a shrinkage and a

37、+ if it is an increase. Whenever possible the results may be expressed in the form of a graph. 8.2 Distortion out of plane For each specimen and for each direction express the distortion out of plane by the distance measured in 7.2.5. 9 Test report The test report shall include the following informa

38、tion: a) reference to this European Standard, i.e. EN 986; b) complete identification of the product tested including type, source and the manufacture reference numbers; c) previous history of the sample; d) values calculated in Clause 8; e) description of the final appearance of the test specimen i

39、ncluding indications of the degree of buckling, saucering, doming, curling and other changes; EN 986:2005 (E) 7 f) details of the measuring instrument used; g) any deviation from this European Standard which may have affected the results.
