This European Standard shall be given the status of a national standard, either by publication of an identical tex
17、t or by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by June 2006. This document supersedes EN 1318:1996. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to im
18、plement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingd

Licensed Copy: Wang Bin, na, Sun Apr 30 02:44:02 BST 2006, Uncontrolled Copy, (c) BSIEN 1318:2005 (E) 4 1 Scope This European Standard specifies a method for the determination of the apparent effective thickness of the backing of textile floor coverings. 2 Normative references The following refe
20、renced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 1957, Machine -made textile floor coverings Selection and cutti
21、ng specimens for physical tests ISO 2424:1992, Textile floor coverings Vocabulary 3 Terms and definitions For the purposes of this European Standard, the following term and definition applies, but see also ISO 2424:1992 for the definition of the terms quoted in Figure A.1. 3.1 apparent effective thi
22、ckness (ea) of the backing distance between the lower surface of the backing and the lowest point of the surface of the layer which is immediately above (back coating, primary backing etc. see Annex A) ignoring any reinforcements included in the backing 4 Principle A transverse cross section of the
23、textile floor covering is examined microscopically and the distance between the upper and lower surfaces of the backing is measured optically, care being taken to ensure that the backing is not compressed in any way. 5 Apparatus 5.1 Optical device with a minimum magnification of x 2, fitted capable
24、of measuring to 0,1 mm accuracy. 5.2 Cutting device to cut the specimens so that the cut edges are clean and rectilinear (for example a press knife or guillotine). 6 Specimens Take a representative full production width sample of the floor covering in accordance with the method given in ISO 1957. Se
25、lect the locations for sampling of three specimens in the form of strips 10 mm to 30 mm wide and 150 mm to 200 mm long, 50 mm from each selvedge with the length of the specimens perpendicular to the direction of manufacture. Attach to the backing a coloured adhesive textile tape carefully choosing t
26、he location to ensure the presence of tape on the longitudinal cross-section of the samples. Ensure adhesion by gently pushing the adhesive tape to the backing. Licensed Copy: Wang Bin, na, Sun Apr 30 02:44:02 BST 2006, Uncontrolled Copy, (c) BSIEN 1318:2005 (E) 5 Cut each strip (backing side up) so
27、 that the cut edges are clean and perpendicular to the underside of the backing. Allow the sample to rest for at least 24 h so that the compressions from the attachment of the adhesive tape and from the cutting can recover. NOTE Clean the cutting knife with acetone after every cutting. This will rem
28、ove any adhesive that was left on the knife and will increase the cleaness of the cut. 7 Test procedure 7.1 For pile carpets Place the specimen on its cut edge so that its longitudinal cross-section with the adhesive tape is within the field of the optical device and focus the image. Align the lower
29、 face of the backing with the reference zero mark on the graduated eyepiece. Record the division number between the zero mark and the mark coinciding with the edge of the lower face of the back-coating in line with the roots of the pile. Carry out three measurements per specimens, evenly spaced over
30、 the specimen. 7.2 For other textile floor coverings Proceed as specified in 7.1 but record the division number between the zero mark and the mark coinciding with the edge of the lower face of the next visible layer above the backing (coating). 8 Calculation and expression of the results Express the
31、 apparent effective thickness of backing (ea) as the mean of the 9 measurements to 0,1 mm. 9 Test report The test report shall contain the following information: a) reference to this European standard i.e. EN 1318; b) mean value of the test results according to Clause 8; c) individual values; d) any
32、 deviation from this standard which may have affected the results.
