Page 4 EN ISO 15880:2004 Paints, varnishes and binders Determination of MEQ value of water-based coating materials and binders 1 Scope This International Standard specifies a titrimetric method for determining the MEQ (milli-equivalent) value of waterbased binders and coating materials, either as an MEQ(acid) value or an MEQ(alkali) value. In contrast to other values, e.g. the acid value, saponification value or hydroxyl value, the MEQ value is always related to the non-volatile matter content of the binder or coating material. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this International Standard. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 3251:1993, Paints and varnishes Determination of non-volatile matter of paints, varnishes and binders for paints and varnishes. ISO 15528:2000, Paints, varnishes and raw materials for paints and varnishes Sampling. 3 Term and definition For the purposes of this International Standard, the following term and definition applies. 3.1 MEQ value the number of milli-equivalents (MEQ) of acid or base contained in 100 g of the non-volatile matter of a waterbased coating material or binder 4 Reagents 4.1 Potassium hydroxide, standard volumetric solution, c(koh) = 0,1 mol/l, in 95 % by volume ethanol or in water. 4.2 Hydrochloric acid, standard volumetric solution, c(hcl) = 0,1 mol/l, in water. 4.3 Perchloric acid, standard volumetric solution, c(hclo 4 ) = 0,1 mol/l, in acetic acid.
