There are many types of wallcovering and varied processes used in their manufacture. To ensure satisfact
20、ory performance, it is important that the installers follow the manufacturers recommended hanging instructions for each particular product. Various grades of washability and colour fastness to light of finished wallcoverings are permitted. These grades will facilitate the selection by the consumer o
21、r specifier of an appropriate wallcovering. Other European Standards on the vocabulary used in the wallcovering industry, wallcoverings for subsequent decoration, textile wallcoverings and heavy duty wallcoverings are also published: EN 235, Wallcoverings in roll form Vocabulary and symbols EN 234,

24、 the designation system. The marking requirements of this standard are primarily for the consumers information to enable optimum selection of the product. This standard applies to finished wallpapers, wall vinyls and plastics wallcoverings not intended for subsequent decoration supplied in rolls for
25、 hanging on indoor walls and ceilings by means of an adhesive covering the whole of the interface between the wallcovering and the support surface. Excluded from this standard are rigid materials, materials not attached or not wholly attached by adhesive, wallcoverings for subsequent decoration, tex
26、tile wallcoverings and non-decorative wallcoverings such as wall linings or those with special properties, e.g. thermal or acoustic insulation. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
27、For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

30、 reference sample sample used for reference purposes to evaluate the changes that have occurred after the various tests carried out on the specimens 4 Categories For the purposes of this standard: BS EN 233:2016EN 233:2016 (E) 6 Category 1 designates the wallcoverings covered by this standard and ch
31、aracterized by a specific width and area Category 2 designates the wallcoverings covered by this standard and characterized by a minimum nominal width threshold Category 3 designates friezes 5 Specifications 5.1 General The dimensions specified for the three categories of covering shall be measured
32、in accordance with the requirements of EN 12956. See Annex A. 5.2 Dimensions 5.2.1 General This applies to the usable dimensions of the product. 5.2.2 Category 1 The area of the roll shall be 5,326 m2 3 %. The nominal width and length of a roll shall be marked. The actual width and length shall not
33、deviate from the nominal values by more than 1,5 %. The nominal width shall be not less than 500 mm and not greater than 530 mm. 5.2.3 Category 2 The nominal width and length of a roll shall be marked. The tolerance on the actual width and length shall be 1,5 %. The nominal width shall be not less t
34、han 600 mm. 5.2.4 Category 3 (friezes) The nominal length of a roll shall be marked. The tolerance on the actual length shall be 1,5 % in the case of roll of length not less than 10 m, otherwise 3 %. The nominal width shall be not less than 32 mm and not greater than 500 mm 5.3 Straightness and para
35、llelity of the edges The straightness and parallelity of the edges shall be measured in accordance with the requirements of EN 12956. The edges of the roll shall be straight and parallel over its entire length, with the following tolerances: straightness: over any 1 m length, the edges shall not dev
36、iate more than 1 mm from straight; parallelity: the 3 width measurements taken in accordance with the requirements of EN 12956 shall not differ by more than 1 mm. 5.4 Spongeability For a wallcovering claimed to be spongeable, it shall be possible to wipe off the hanging adhesive while it is still da
37、mp from the front face of the wallcovering with a damp cloth or sponge without causing visible damage. BS EN 233:2016EN 233:2016 (E) 7 Accordingly, a wallcovering subjected to the spongeability test described in EN 12956 shall exhibit no damage or change likely to alter its appearance as a wallcover
38、ing. This symbol indicating this spongeable level shall be as given in EN 235. 5.5 Washability If a wallcovering is claimed to be washable during its life after hanging, it shall be qualified as washable, extra-washable or scrubbable according to its grade of washability. When tested under the test
39、conditions specified for each level of washability by EN 12956, a wallcovering shall exhibit no damage or change Iikely to alter its appearance as a wallcovering compared with the reference sample. The symbols indicating the washability levels shall be as given in EN 235. 5.6 Colour fastness to ligh
40、t The numerical rating for colour fastness to light shall be determined in accordance with the requirements of EN ISO 105-B02 at a relative humidity of 60 % to 70 % and a maximum black panel temperature of 45 C. A wallcovering conforming to this standard shall have a rating of not less than 4. The s
41、ymbols illustrating the levels of colour fastness to light shall be as given in EN 235. 5.7 Maximum migration of heavy metals and certain other elements 5.7.1 Test method The test method shall be method A of EN 12149. 5.7.2 Requirements The migration of heavy metals and specific elements, expressed
42、as mg/kg of wallcovering, shall not exceed the values in Table 1. 5.7.3 Interpretation of results The analytical results obtained from the tests specified in EN 12149 shall be corrected by subtracting the value of the analytical correction factors given in Table 2 in order to obtain a corrected anal
43、ytical result. Wallcoverings shall be considered to meet the requirements of this European Standard if the corrected analytical result does not exceed the limits indicated in Table 1. NOTE Given the precision of the methods specified in this European Standard, it is necessary to use the corrected an
44、alytical result to take into account the results of interlaboratory tests. EXAMPLE Analytical result for lead: 120 mg/kg. Corresponding analytical correction in Table 2: 30 %. Corrected analytical result = 120 - (120 x 30) /100 = 120 - 36 = 84 mg/kg. This is regarded as satisfying the requirements o
45、f the standard (lead: 90 mg/kg).
