21、 irhgts seredevr Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subj
22、ect for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IE
23、C) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Interna
24、tional Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.
25、 International Standard ISO 13803 was prepared by Technical Committee ISO/TC 35,Paints and varnishes, Subcommittee SC 9,General test methods for paints and varnishes. Annex A forms an integral part of this International Standard. EN ISO 13803:2004 INTENRATIONAL TSANDADRISO 30831:(0002)E ISO 0002 All
26、 irhgts seredevr1 Paints and varnishes Determination of reflection haze on paint films at 20 1Scope This International Standard is one of a series of standards dealing with the sampling and testing of coating materials such as paints and varnishes, as well as coatings prepared from them. It specifie
27、s a test method for measuring at 20 the reflection haze of paint coatings. The use of this geometry means that the method is closely related to the measurement of specular gloss at 20 in ISO 2813. The application of this method is intended to give improved differentiation between high-gloss surfaces
28、, for example in the field of assessment of dispersion characteristics. The method is therefore a useful complement to ISO 8781-3 which uses specular gloss measurements. For decorative coatings (e.g. automotive coatings), reflection haze is also an important criterion in evaluating the quality of th
29、e coating, in addition to colour and specular gloss. The results obtained often depend on the following properties of the paints: a)the binder system used and the composition of the paint; b)the wetting and dispersing properties of the pigments; c)the method of application; d)the orientation of the
30、test sample with respect to the plane of measurement. 2Normative 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
31、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
32、to applies. Members of ISO and IEC maintain registers of currently valid International Standards. ISO 1513:1992,Paints and varnishes Examination and preparation of samples for testing.

35、poses of this International Standard, the following term and definition apply. 3.1 reflection haze ratio of the luminous flux reflected and diffusely scattered from an object adjacent to the specular direction for a specified source and receptor angle to the luminous flux reflected from glass with a
36、 refractive index of 1,567 in the specular direction, this glass being assigned the value of 100 on the linear reflection haze scale. NOTEThe measurement of reflection haze is related to the measurement of specular gloss in accordance with ISO 2813. Therefore, this International Standard has been ad
37、apted, as closely as possible, to ISO 2813 and should be read in conjunction with ISO 2813. The main difference between the two standards is that specular gloss is measured in the specular direction and reflection haze is measured in slightly different directions. 4Apparatus and materials 4.1Substra
38、te The substrate should preferably be agreed on between the interested parties. In the absence of such an agreement, the substrate shall be plate glass of mirror quality, preferably of a thickness of at least 3 mm, and have a minimum test area of 150 mm ? 100 mm. The larger dimension shall be at lea
39、st equal to the length of the illuminated area. NOTEAlthough the method, as written, is restricted to paints, clear varnishes may be tested by using as the substrate either black or clear glass roughened and covered on the back and edges by black paint. 4.2Film applicator Use a block applicator havi
40、ng a recess ground in the underface to form a gap (150 ? 2) ?m deep when placed on an optically plane surface, or another suitable means, to apply the test coating. NOTEThe block applicator produces a wet-film thickness of approximately 75 ?m. 4.3Hazemeter The hazemeter shall consist of a light sour
41、ce and a lens that directs a parallel beam of light onto the surface under test, plus a receptor housing containing a lens, field stop and photoelectric cell to receive the required cone of reflected light. The hazemeter shall have the following characteristics: a)Geometry: The axis of the incident
42、beam shall be at an angle ?1= (20 ? 0,1) (see Figure 1) to the normal to the surface under test. The axis of the receptor shall be coincident with the mirror image of the axis of the incident beam to within ? 0,1. With a flat piece of polished black glass or a front-silvered mirror in the test panel
43、 position, an image of the light source shall be formed at the centre of the receptor field stop 1)To be published. (Revision of ISO 7724-2:1984) 2)To be published.

44、neral disposition of the main features). To be certain of averaging out any surface uneveness, the width of the illuminated area on the test panel shall be significantly larger than possible surface irregularities: a generally accepted value is 10 mm. The dimensions of and tolerances on the image ap
45、erture and receptor aperture shall be as indicated in Table 1. The angular dimensions of the receptor field stop shall be measured from the receptor lens.
