International organizations, governmental and non-governmental, in liaison with ISO, also take part in the

ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.

23、method for determining the flow characteristics of a fused thermosetting coating powder down a plane inclined at a set angle to the horizontal.The result of the test described in this Part of ISO8130 gives an indication of the degree of melt flow that may occur during the curing of the coating powde

24、r. This characteristic contributes to the coherence of the coating, to its surface appearance and to the degree of coverage over sharp edges.The test acts as a useful method for checking for batch to batch variation in the behaviour of a given coating powder. Correlation between the results from coa

25、ting powders of differing composition is not to be expected.This method is unlikely to yield meaningful results with coating powders which have gel times of less than one minute at the test temperature when characterised according to ISO8130-6.2 Normative referencesThe following standards contain pr

26、ovisions which, through reference to this text, constitute provisions of this Part ofISO8130. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this International Standard are encouraged to investigate the possibi

27、lity of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid International Standards.ISO 8130-2:1992, Coating powders Part2: Determination of density by gas comparison pyknometer (referee method).

ISO 8130-9:1992, Coating powders Part9: Sampling. 3 PrincipleThe thermosetting coating powder is pressed into a pellet of

29、 standard size which is allowed to melt and flow down a heated inclined plate. The extent of flow is measured.4 Apparatus4.1 Fan-assisted air circulation oven, capable of maintaining temperatures up to250C. The circulation fan shall be capable of being turned on and off as required.4.2 Glass plates,

30、 of suitable dimensions to undertake the test.NOTE 1Photographic float-glass plates have been found to be suitable.As an alternative metal plates may be used. However, these will need to be closely defined with respect to their composition and surface finish. The plates shall be sufficiently rigid s

31、o as not to flex during the test. The details of the metal plates shall be included in the test report (clause9).4.3 Plate assembly, of suitable metal, that fits inside the oven(4.1). The assembly shall be capable of carrying one or more of the plates(4.2) in a horizontal position and at an angle of

32、 (65 1) to the horizontal when moved by a lever projecting through the side of the oven.4.4 Balance, capable of measuring to10mg.4.5 Steel pellet-moulding press, together with a knockout rod, to make pellets of (12,5 0,05)mm in diameter and (6,5 0,2)mm thick.4.6 Steel rule, graduated in mm.4.7 Polyt

33、etrafluoroethylene, (PTFE) release aerosol spray5 SamplingTake a representative sample of the product under test as described in ISO8130-9.6 ProcedureCarry out the determination in duplicate.6.1 Weigh in the balance(4.4) to an accuracy of10mg a mass of the product under test equivalent in grams to h

34、alf of the density of the coating powder in accordance withISO8130-2 or ISO8130-3. By means of the pellet press(4.5) compact the pellet into a disc (6,5 0,2)mm thick and push the pellet out of the mould with the knockout rod. Weigh the pellet to confirm that its mass is correct to10mg.If there is a

35、delay between the commencement of the test and the preparation of the pellet, protect it against moisture absorption by storage in a desiccator or a sealed bag.6.2 Unless otherwise agreed the temperature of the test shall be the recommended stoving temperature. In the absence of this information a t

36、emperature of(180 2)C shall be used.6.3 Spray the uppermost side of the glass plate(s)(4.2) with the PTFE release material(4.7) and allow to air dry.BS EN ISO 8130-11:2010EN ISO 8130-11:2010 (E)2 BSI 2011The use of PTFE release material is in order to facilitate the removal of the sample so that the

37、 glass test plate may be reused and to ensure that a uniform surface is obtained. This procedure may be considered inappropriate when metal plates are used. It may be omitted on agreement between interested parties in which case this shall be indicated in the test report (clause9).6.4 Place the plat

38、e(s) in the plate assembly(4.3) in a horizontal position.6.5 Place the plate assembly and plate(s) into the oven set at the appropriate temperature (seeclause6.2) and allow the assembly to preheat for a minimum period of15minutes with the fan on.NOTE 2It may be more convenient to maintain the plate

39、assembly in the oven and carefully load the plate(s) in situ.6.6 At the end of the preheat period turn off the circulation fan and open the door of the oven. Place the pellet(s) towards the end of the plate(s) which will be uppermost when tilted. Close the door of the oven and restart the fan. This

40、operation shall take no longer than15s to perform. After a further15s since closing the oven door operate the plate assembly to bring the plate(s) to (65 1) to the horizontal. Allow the plate(s) to remain in this position for15minutes. At the end of this period remove the plate(s) from the oven and

41、allow to cool to room temperature in a horizontal position.6.7 Using the steel role(4.6) measure the total length of the flowed pellet in mm. This is most conveniently undertaken with glass plates by viewing from the reverse side. Record the measurement to the nearest0,5mm.7 Expression of resultsCal

42、culate the pellet flow by deducting the original diameter of the pellet (12,5mm) from the total flow as measured inclause6.7.If the two determinations differ by more than5% based on the lower figure, repeat the procedure described inclause6.Calculate the average of two valid determinations and repor

43、t to the nearest0,5mm.8 PrecisionThe precision of the method, as obtained by statistical examination of interlaboratory test results, is as follows:8.1 Repeatability (r)The value below which the absolute difference between two single test results, each the mean of duplicates, obtained on identical m

44、aterial by one operator in one laboratory within a short interval of time using the standardized test method, may be expected to lie with a95% probability is5%.9 Test reportThe test report should contain at least the following information:a) all details necessary to identify the product tested;b) a

45、reference to this part of ISO8130 (ISO8130-11);c) the test temperature;d) weight of sample;e) results of the test (individual values and mean value);f) whether a metal plate was used and a description of its surface finish and composition (sub-clause4.2);g) whether a PTFE pre-treatment of the plate

46、was used (sub-clause6.3);h) any deviation from the test method specified;i) the date of the test.BS EN ISO 8130-11:2010EN ISO 8130-11:2010 (E)3blankBSI GroupHeadquarters 389 Chiswick High Road, London, W4 4AL, UK Tel +44 (0)20 8996 9001 Fax +44 (0)20 8996 7001 standardsBSI - British Standards Insti
