EN 12281:2002 (E)4IntroductionPaper for use in dry toner imaging processes, the common copy paper, represents one of the major grades of theworld's paper market. Most copier machines, laser-printers and similar machines work with dry toner imaging. Forsimplification only the terms "copy paper" and "copier machine" are used.It is not possible to define performance of a copy paper by physical properties alone. Therefore, CEN/TC 172 has putaside several technical paper characteristics and focused on defining and specifying the equivalents of "printability"and "runnability", as well as those paper properties that appeal directly to the end-user.Since a standard copier machine does not exist and customer demands on some accommodating and aestheticaspects will vary, several characteristics were not given a required value. In such cases, though, test methods areprovided that will facilitate the making of adequate agreements between supplier and customer.1 ScopeThis European Standard specifies the performance requirements for uncoated cut-size paper for dry toner imagingprocesses (i.e. copy paper), in 80 g/m² and in A4 format based on EN ISO 216. Other grammages and sizes of theISO-A series are covered by this European Standard, as long as the requirements specified in this EuropeanStandard are fulfilled.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 hereafter. 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 (including amendments).EN 12283:2002, Printing and business paper — Determination of toner adhesion.EN ISO 186, Paper and board — Sampling to determine average quality (ISO 186: 2002).EN ISO 216, Writing paper and certain classes of printed matter — Trimmed sizes — A and B series(ISO 216:1975).EN ISO 536, Paper and board — Determination of grammage (ISO 536:1995).EN 20187, Paper, board and pulps — Standard atmosphere for conditioning and testing and procedure formonitoring the atmosphere and conditioning of samples (ISO 187:1990).EN 20287, Paper and board — Determination of moisture content — Oven drying method (ISO 287:1985).EN 20534.
