19、 8130 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 determination of the equivalent-sphere particle size distribution of coating powders by laser diffraction and is suitable for discriminating between pa

20、rticles of the size range from 1 m to 300 m. This method is applicable only for dry powders. NOTE Most instruments will be capable of discriminating between particles of sizes beyond these limits. 2 Normative references The following normative documents contain provisions which, through reference in

21、 this text, constitute provisions of this part of ISO 8130. For dated references, subsequent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 8130 are encouraged to investigate the possibility of applying the most recent

22、 editions of the normative documents indicated below. For undated references, the latest edition of the normative document referred to applies.

24、and definition For the purposes of this part of ISO 8130, the following term and definition apply. 3.1 obscuration percentage or fraction of incident light that is attenuated due to extinction (scattering and/or absorption) by the particles of a coating powder NOTE A full list of definitions is give

26、urce. The light scattered by the particles at various angles is measured by a multi-element detector and numerical values relating to the scattering pattern are recorded for subsequent analysis. These numerical scattering values are then transformed using an appropriate optical model and mathematica

27、l procedure to yield the proportion by volume of the sample in each size class forming a sphere-equivalent volumetric particle size distribution. 5 Apparatus NOTE A description of laser analyser apparatus is given in ISO 13320-1. 5.1 Laser diffraction particle size analyser, with a minimum size rang

28、e of 1 m to 300 m. 5.2 Dry-powder feeder, to be connected to the laser apparatus. This shall incorporate suitable means of delivering a constant stream of powder, free from agglomerates, into the analyser. 5.3 Compressed-air supply, delivering sufficient pressure as recommended by the instrument sup

29、plier. The air shall be dry, free from oil and filtered to 4 m. 5.4 Air extraction system, capable of extracting air at the rate required by the instrument manufacturer. Certain domestic vacuum cleaners may be found to be suitable. The vacuum unit shall be located such that the output of hot air doe

30、s not reach the measurement zone. Ensure that all particle-transporting devices, such as the dry-powder feeder, vacuum inlets and hoses, are electrically earthed to prevent electrostatic discharges. 5.5 Computer and software, suitable for analysing the data from the measurement device. The computer

31、may be connected to a suitable printer. Any special requirements for the specifications of computer hardware will normally be advised by the instrument manufacturer. 5.6 Spatula or spoon. 6 Sampling Prepare a representative sample of the powder to be tested, as described in ISO 8130-9. A quantity be

32、tween 3 g and 5 g is normally sufficient for each determination. 7 Conditions Measurements shall be made under standard conditions as specified in ISO 3270. The period of conditioning shall be not less than 30 min. 8 Procedure NOTE 1 It is recommended that the operator be familiar with the procedure

33、s detailed in ISO 13320-1. WARNING The radiation from instruments equipped with a low-power laser can cause permanent eye damage. Never look in the direct path of the laser beam or its reflections. Avoid cutting the laser beam with reflecting surfaces. Observe the local laser radiation safety regula

34、tions. Carry out the measurements in duplicate. 2BS EN ISO 8130-13:2010EN ISO 8130-13:2010(E) Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 14/06/2011 08:48, Uncontrolled Copy, (c) BSIInstall and adjust the apparatus in accordance with the manufacturers instructions for powder of the expect

35、ed particle size range. When the system is switched on at the start of a series of determinations, allow at least 30 min to elapse to enable the equipment to stabilize, referring to the manufacturers instructions as necessary. Check that the laser beam is centrally aligned on the detector, and adjus

36、t if necessary. NOTE 2 With most instruments alignment will take place automatically, but it may be necessary for it to be carried out by a service engineer. Using the spatula or spoon (5.6), add the powder to the powder feeder (5.2) and adjust the air flow as recommended by the instrument supplier.

37、 Make a background measurement (i.e. in the absence of powder) to determine the combined effect of electrical “noise” and contamination in the system. This measurement needs to be subtracted from the sample measurement. NOTE 3 This procedure is normally undertaken automatically by the instruments co

38、mputer. Start the powder feeder in accordance with the instructions such that the level of obscuration (see 3.1) lies between 1 % and 15 %, preferably between 7 % and 10 %. Allow the powder sample to pass through the air cell, using a brush to remove any fines remaining in the feed tray. After the d

39、etermination, the data are displayed on the computer visual display unit (VDU). Ensure the instrument is thoroughly cleaned between determinations. At the end of a measuring session, the computer software may be closed down and the device turned off. 9 Calculation of results As noted above, the comp

40、uter software, associated with the particle size analyser, will undertake the calculations and allow the results to be displayed (and, if required, printed) in both tabular and graphical form. NOTE In general, the Fraunhofer theory will be applied (see ISO 13320-1) and details of refractive indices

41、will not be required. However, in the case of unpigmented coating powders it may be necessary to use Mie theory, in which case refractive indices will be required. If the results of the two determinations for any size class differ by not more than 1 %, calculate the arithmetic mean. Otherwise, under

42、take a third determination and report the arithmetic mean of all three measurements, noting this in the test report. 10 Expression of results Express the results in accordance with ISO 9276-1. 11 Precision Experience shows that repeatability within 1 m in the range up to 100 m particle diameter may

43、be expected. 3BS EN ISO 8130-13:2010EN ISO 8130-13:2010 (E) Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 14/06/2011 08:48, Uncontrolled Copy, (c) BSI12 Test report The test report shall include at least the following information: a) all details necessary to identify the product tested; b)
