    16、dISO (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 subject for which a technical

    17、 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 (IEC) on all matters of elec

    18、trotechnical standardization.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least75% of the member bodies casting a vote.International Standard ISO8130-12 was prepared

    19、by Technical CommitteeISO/TC35, Paints and varnishes, Subcommittee SC9, General test methods for paints and varnishes.ISO8130 consists of the following parts, under the general title Coating powders: Part1: Determination of particle size distribution by sieving; Part2: Determination of density by ga

BSI 2011BS EN ISO 8130-12:2010EN ISO 8130-12:2010 (E) BSI 2011 11 ScopeThis part of ISO8130 is one of a series of standards dealing with the sampling and testing of paints, varnishes and related products.It specifies a method for the dete

    23、rmination of the tendency for the mixing of two different coating powders to result in the deterioration of the surface quality of the final coating. The results depend on the following characteristics of the coating powders:a) their chemical reactivity;b) their chemical composition;c) their melt pr

    24、operties.The onset of the deterioration in appearance, its nature and its extent will depend greatly on the ratio in which the powders are mixed.The test is useful in predicting the possibility of incompatibility arising from mixing different powders both during the manufacturing process and during

    25、the application of the coating powder.The nature of the deterioration in surface appearance may manifest itself in various ways, including: change in gloss level; the presence of pinholes, including micro-pinholes; the appearance of orange peel; the presence of craters; the presence of bittiness (gr

    26、aininess); the presence of colour contamination.NOTEDeterioration in mechanical properties may also be experienced. However, this part of ISO8130 is only concerned with changes in appearance.2 Normative referencesThe following standards contain provisions which, through reference in this text, const

    27、itute provisions of this part of ISO8130. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO8130 are encouraged to investigate the possibility of applying the most recent editions of the standards

    28、indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.ISO8130-9:1992, Coating powders Part9: Sampling. ISO1514:1993, Paints and varnishes Standard panels for testing. ISO2813:1994, Paints and varnishes Determination of specular gloss of non-metallic pa

    29、int films at20,60 and85. 3 PrincipleThe coating powders are mixed together in a range of ratios and each mixture is applied to standard test panels, stoved and the surface inspected for evidence of incompatibility.4 ApparatusOrdinary laboratory apparatus, together with the following:4.1 Clean and de

    30、greased steel panels, as described in ISO1514, with holes drilled at one end for hanging.4.2 Powder spray system, consisting of a corona charge gun or a tribo charge gun and an air extraction spray booth with a suitable powder collection device.4.3 Suitable clean container, capable of holding a mass

    31、 of the powder suitable for processing in the spray system(4.2).NOTEPlastic bags have been found to be suitable for non-metallic powders.4.4 Balance, accurate to10mg.4.5 Oven, capable of stoving the coated test panels.BS EN ISO 8130-12:2010EN ISO 8130-12:2010 (E)2 BSI 20115 SamplingPrepare a represe

    32、ntative sample of the powder under test, as described in ISO8130-9. The quantity of powder required will depend on the powder spray system(4.2).NOTEA quantity of between10g and200g is normally suitable for each test.6 ProcedureCarry out the test in duplicate.6.1 In the absence of agreement between t

    33、he interested parties, prepare mixtures in the following mass ratios in a quantity required for the test, weighing each component to an accuracy of10mg: 6.2 Place each of the samples prepared in6.1 in a clean container(4.3) and agitate for sufficient time to ensure complete homogenization.NOTEVigoro

    34、us shaking by hand of a partially filled container for15s to30s has proved to be adequate.6.3 Spray each of the mixed samples onto a test panel(4.1), using the spray gun(4.2), to a thickness appropriate to the application.It is extremely important that the spraying apparatus is thoroughly cleaned be

    35、tween each application. In any case, it is mandatory that the order of application of the samples be in increasing order of each minor constituent, thus:100,0 A:0,0 B to50,0 A:50,0 Band then:100,0 B:0,0 A to90,0 B:10,0 A.6.4 Place the coated panels in the oven(4.5) and stove in accordance with the p

    36、rescribed stoving schedule of the slower-reacting component. If no schedule is available, it shall be agreed on between the interested parties.6.5 Remove the panels from the oven and allow to cool.6.6 Examine the coated surfaces for pinholes, craters and other imperfections.NOTEWhere appropriate, a

    37、quantitative measure of change in gloss may be obtained by measuring gloss values in accordance with ISO2813.7 Expression of resultsA verbal description of the appearance of the coatings will be sufficient for the purposes of this standard method. Where quantitative measurements of gloss have been u

    38、ndertaken, these shall be quoted numerically.NOTEAs very small amounts of contamination can greatly influence the level of gloss, it may be useful to plot the gloss measurements graphically. In this case, it is recommended that a probability chart be employed in which the gloss measurements are plot

    39、ted as abscissae and the mass ratios of the powders in the mixture are plotted as a probability distribution on the ordinate scale. In this way, it is possible to obtain a compatibility curve in which the influence of small concentrations of one powder on the other are clearly demonstrated.8 Precisi

    40、onPrecision data are inappropriate for non-quantitative measurements. The precision of any gloss measurements shall be as detailed in ISO2813.9 Test reportThe test report shall contain the following information:a) all details necessary to identify the products tested;b) a reference to this part of I

    41、SO8130 (ISO8130-12);c) the recommended stoving schedule for each powder;d) the stoving schedule used in the test, if no schedule is available (see6.4);e) the gun used, i.e.either corona or tribo (see4.2);Powder A 100,0 99,9 99,0 90,0 50,0 10,0 1,0 0,1 0,0Powder B 0,0 0,1 1,0 10,0 50,0 90,0 99,0 99,9
