EN ISO 10601:2008 (E) DIN EN ISO 10601:2008-08 3 Introduction Micaceous iron oxide pigments were previously included in ISO 1248 (classified in the colour group “grey with metallic sheen”) but are explicity excluded from the r
21、evised edition published in 2006. In this revised edition of ISO 10601, the requirements for micaceous iron oxide pigment have been defined more clearly and relate to an essentially lamellar particle shape. Micaceous iron oxide pigments can vary in composition, particle size range, and particle shap
22、e depending on whether they are produced synthetically or, if a refined natural oxide, on the location where the ore was mined. The primary use of micaceous iron oxide is in protective coatings for steelwork, and for optimum performance the pigment should have a high content of thin flake-like parti
23、cles. The protective action is ascribed to the close packing of pigment platelets within the paint film, forming overlapping layers that lie roughly parallel to the substrate. This impedes penetration of corrosion promoters, reduces ultra-violet degradation of the binder and improves film strength.
24、For less critical requirements, micaceous iron oxide pigment with a lower content of thin flakes may be acceptable. Therefore in this International Standard, micaceous iron oxide pigments are classified into two groups according to their thin-flake content as determined by microscopic examination (s
25、ee Table 1). For the purposes of this International Standard, pigments with a lamellar-particle content below 50 % are not considered to be “micaceous” or classified as “lamellar”. DIN EN ISO 10601:2008-08 EN ISO 10601:2008 (E) 4 1 Scope This International Standard specifies the requirements and cor
26、responding test methods for manufactured and natural micaceous iron oxide (MIO) pigments, in dry form, used primarily in protective coatings for steelwork. In accordance with current practice, the general requirements for micaceous iron oxide pigments have been sub-divided to give a) those requireme
27、nts that are essential (see Table 2) and b) those requirements that are conditional upon prior agreement between the interested parties (see Table 3). In certain instances, reference may be made to an agreed reference pigment. 2 Normative references The following referenced documents are indispensab

32、lso known as specular haematite) or a manufactured product consisting essentially of iron(III) oxide, Fe2O3, that is grey in colour with a metallic sheen and consists essentially of particles having lamellar form 4 Classification In this International Standard, micaceous iron oxide pigments are clas
33、sified by grades according to their thin-flake content as shown in Table 1 and by types according to their residue on sieve as shown in Table 2. Thin-flake micaceous iron oxide particles are defined as having a thickness such that they appear as sharply defined red translucent platelets when viewed
34、under an optical microscope by transmitted light, i.e. with the light source behind the specimen under examination (see test method in Clause 7).

EN ISO 10601:2008 (E) DIN EN ISO 10601:2008-08 7 7.3 Procedure
42、Prepare a microscope slide (7.2.1) by one of the following methods: a) Place a few milligrams of a representative sample of the dry pigment (see Clause 6) on the glass slide. Add a few drops of refined linseed oil (7.1.1) and gently incorporate the pigment into the oil using the glass rod (7.2.2). P
43、lace the cover slip over the pigment/oil dispersion and position on the microscope stage. b) Spread a few milligrams of the sample of the dry pigment on the glass slide and examine it in the way described below without adding linseed oil. Adjust the intensity of the light below the slide to the high
44、est practical level. Focus sharply at 200 magnification and scan the slide until a field of view is obtained that is considered to be representative, and in which at least 50 particles can be seen. Thin-flake micaceous iron oxide particles appear as sharply defined red translucent platelets, whilst
45、thicker and/or granular particles appear as black shapes. Assess the proportion of red to black particles and classify as the appropriate grade (see Table 4). Table 4 Thin-flake content Grade Appearance Thin-flake content % A High proportion of red particles 65 B Considerable proportion of red parti
46、cles 50 to 65 If the thin-flake content is not obvious, count the number of red and black particles in a group of at least 50 particles. A frame-image device is recommended to assist in this operation. Repeat the count on a duplicate slide and calculate the mean percentage of red particles. Typical
