DIN EN ISO 4619:2011-02 EN ISO 4619:2010 (E) 3 1 ScopeThis International Standard specifies the requirements and the corresponding test methods for driers for paints,varnishes and related products. The requirements relate to driers in the solid or liqu
27、id form.CAUTION The procedures described in this International Standard are intended to be carried out byqualified chemist or by other suitably trained and/or supervised personnel. The substances and proceduresused in this method may be injurious to health if adequate precautions are not taken. This
28、 InternationalStandard refers only to its technical suitability and does not absolve the user from statutory obligationsrelating to health and safety.Attention is particularly drawn to the health hazards of heavy metals which may be a constituent of driers(e.g. cobalt, lead, cerium, zirconium, vanad
29、ium; see clauses 3, 4 and 8).2 Normative referencesThe following standards contain provisions which, through reference in this text, constitute provisions of thisInternational Standard. At the time of publication, the editions indicated were valid. All standards are subject torevision, and parties t
30、o agreements based on this International Standard are encouraged to investigate thepossibility of applying the most recent editions of the standards indicated below.

35、rder to acceleratethis process.4 Descriptions4.1 Solid driersSolid driers are materials which may be manufactured in a hard, soft (highly viscous) or powder form.4.2 Liquid driersLiquid driers are materials which are supplied as solutions in organic solvents, usually white spirit.NOTE Emulsifiable d
36、riers are also available, but no requirements for this type are given in this International Standard.All these types of drier, when dissolved in solvents (normally hydrocarbons), impart specific drying propertiesdepending on the metal used.4.3 Metals usedThe following metals are used: cobalt, mangan
37、ese, lead, zinc, calcium, cerium (or other rare earths), iron,zirconium, vanadium, barium, aluminium, strontium, etc.NOTE In this International Standard, methods for determination of metal content are given only for those metals which arein common use.4.4 Acids usedThe following acids are used: fatt
38、y acids of linseed oils, tall-oil fatty acids, resinic acids, naphthenic acids,2-ethylhexanoic acid, fatty iso-acids with 9 carbon atoms, other fatty acids with 9 to 11 carbon atoms, etc.5 Requirements and test methods5.1 Driers for paints shall comply with the requirement given in table 1.5.2 Drier
39、s named according to the commercial name of the main acid used shall contain at least 90 % of this acid,except for driers based on naphthenic acids, which shall contain at least 70 % of these acids, expressed as apercentage of the total mass of acid present.NOTE If desired, the type and content of t
40、he acids may be determined by gas-chromatographic (GC) analysis, except inthe case of naphthenic acids.6 SamplingTake a representative sample of the drier to be tested, as described in ISO 842.DIN EN ISO 4619:2011-02 EN ISO 4619:2010 (E) 5 Table 1 Requirements and test methodsCharacteristic Requirem
