EN 13558:2003 (E)3ForewordThis document (EN 13558:2003) has been prepared by Technical Committee CEN /TC 163, "Sanitary appliances",the secretariat of which is held by UNI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by March 2004, and conflicting national standards shall be withdrawn at the latest byMarch 2004.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.SIST EN 13558:2004



EN 13558:2003 (E)41 ScopeThis European Standard specifies the properties of impact modified extruded acrylic sheets from which showertrays for domestic purposes are manufactured.Note : For the purposes of this standard the term "domestic purposes" includes use in hotels, accommodation for students,hospitals and similar buildings, except when special medical provisions are required.2 Normative referencesThis European standard incorporates by dated or undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listed herafter. Fordated references, subsequent amendments to or revisions of any of these publications apply to this EuropeanStandard only when incorporated in it by amendment or revision. For undated references the latest edition of thepublication referred to applies.ISO 105-A02, Textiles - Tests for colour fastness – Part A02: Grey scale for assessing change in colour.ISO 179, Plastics - Determination of Charpy impact properties.ISO 306, Plastics - Thermoplastic materials - Determination of the Vicat softening temperature (VST).ISO 527, Plastics - Determination of tensile properties.ISO 4892, Plastics - Methods of exposure to laboratory light sources.ISO 7823-2, Plastics - Poly(methyl methacrylate) sheets - Types, dimensions and characteristics - Part 2: Extrudedsheets3 Terms and definitionsFor the purpose of this standard, the following term and definition applies:3.1Impact modified extruded acrylic sheetsheet produced by extrusion of homopolymers and copolymers of methyl methacrylate (MMA) containing at least80% (m/m) of MMA and not more than 20% (m/m) of acrylic esters or other useful monomers, modified by acrylicelastomers grafted by homopolymers or copolymers of MMA. The polymers may contain lubricants, processingaids, U.V. absorbers, pigments and colours.4 Requirements4.1 General requirementsThe impact modified extruded acrylic sheet shall comply with the requirements of table 1 when tested to themethods given in Table 1.SIST EN 13558:2004

In the case of coloured sheet, the colourantshall be incorporated during the manufacture of the sheet and the colour shall be throughout the thickness of thematerial. Colour standards shall be agreed between sheet manufacturer and fabricator.4.5 Thermal stabilityWhen tested according to the method given in 5.2 the impact modified extruded sheet shall show no evidence ofblistering.4.6 Colour fastness4.6.1 Resistance to UV lightWhen tested in apparatus complying with the requirements of the xenon arc lamp method of ISO 4892 for 250 hthe colour change noted in the impact modified extruded sheet shall be recorded in terms of the grey scale forassessing colour change specified in ISO 105-A02. The fastness rating shall be not less than grade 3.The xenon lamp shall only be used when its age is between the limits stated by the manufacturer of the lamp to bethe useful life of the lamp or, where the useful life is not stated, is between 10 h and 600 h.SIST EN 13558:2004
