National foreword This document (EN ISO 8623:2015) has been prepared by Technical Committee ISO/TC
5、35 “Paints and varnishes” in collaboration with Technical Committee CEN/TC 139 “Paints and varnishes” (Secretariat: DIN, Germany). The responsible German body involved in its preparation was DIN-Normenausschuss Beschichtungsstoffe und Beschichtungen (DIN Standards Committee Coatings and Coating Mate
6、rials), Working Committee NA 002-00-02 AA Lackrohstoffe. The method for the determination of unsaponifiable matter (diethyl ether method) as in ISO 150:1980 has been adopted as a standard method by the International Union of Pure and Applied Chemistry (IUPAC) in the fifth edition of its “Standard me
7、thods for the analysis of oils, fats and derivatives”, Section “Oils and fats”. It corresponds to the method previously specified in DIN 55934:1982-11, 14.3. The formula for calculating the rosin acids content (see B.5) includes a factor of 1,042 to correct for the slight esterification of rosin aci
8、ds, and a factor of 0,1 to correct for the unesterified acids, in accordance with the Scandinavian technical rule SCAN-T 14:78. Because the reference values for the composition of tall-oil fatty acids given in DIN 55961:1993-03 have not been included in ISO 8623, they are included in the informative
9、 National Annex to the present standard. However, the content for some fatty acids has not been given, as there has not yet been enough experience with them. For example, limiting the all-cis-9,12,15-octadecatrienoic acid content to less than 1 % in order to reduce yellowing is currently under consi
10、deration. If this seems necessary, e.g. due to the results of investigations, then this content can be specially agreed. The DIN Standards corresponding to the International Standards referred to in this document are as follows: ISO 150 DIN EN ISO 150 ISO 383 DIN 12242-1 ISO 2114 DIN EN ISO 2114 ISO

12、lues; b) the data for unsaponifiable matter content has been changed from mass fraction of max. 2 % to max. 5 %; DIN EN ISO 8623:2015-12 3 c) the method for the determination of the unsaponifiable matter (diethyl ether method) has been taken from ISO 150, 1980 edition, because it is no longer includ
13、ed in the current edition of ISO 150, i.e. ISO 150:2006; d) the concentration of phenolphthalein indicator solution has been changed from 10 g/l in ethanol to 5 g/l in ethanol or in a 1:1 ethanol/water mixture.
