22、8 BSI 04-1999 iii 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 sub
23、ject 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 (I
24、EC) on all matters of electrotechnical 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 Stand
25、ard ISO105-Z05 was prepared by Technical Committee ISO/TC38, Textiles, Subcommittee SC1, Tests for coloured textiles and colorants. ISO105 was previously published in thirteen “parts”, each designated by a letter (e.g.“Part A”), with publication dates between 1978 and 1985. Each part contained a ser
26、ies of “sections”, each designated by the respective part letter and by a two-digit serial number (e.g.“Section A01”). These sections are now being republished as separate documents, themselves designated “parts” but retaining their earlier alphanumeric designations. A complete list of these parts i
27、s given in ISO105-A01. Annex A and Annex B of this part of ISO105 is for information only.

28、 is an important feature when considering aspects of hygiene, health and safety in the dyestuff-consuming industry. It is important therefore that a reliable and reproducible method exists to measure this property. Although other methods for dust measurement exist, the method given in this part of I
29、SO105 is both more representative of and comparable with actual practice when handling dyestuffs. In respect of a comparison of dyestuffs or the reliability of limits, it should be understood that the resulting value is not a specific value like density. Details of reproducibility data are given in
30、Annex A. 1 Scope This part of ISO105 specifies a method for determination of the dusting behaviour of dyes. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO105. At the time of publication, the editions
31、indicated were valid. All standards are subject to revision, and parties to agreements based on this part of ISO105 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of currently valid Intern
32、ational Standards. ISO105-A01:1994, Textiles Tests for colour fastness Part A01: General principles of testing. ISO105-A03:1993, Textiles Tests for colour fastness Part A03: Grey scale for assessing staining. 3 Definition For the purposes of this part of ISO105, the following definition applies. 3.1
33、 dust particles of solid material dispersed in a gas NOTE 1Dyestuff dust is formed during handling operations such as dispensing, transferring, sprinkling, etc. NOTE 2Solid dyes are sold in different physical forms (powdered, granulated, etc.). The particle-size distribution of commercial products v
34、aries considerably. The mean particle diameter may be less than504m or as much as several millimetres. The range of the particle-size distribution of a solid dye may also be narrow or wide. NOTE 3The particle-size distribution of dyestuff dust is largely independent of the physical form of the dyest
35、uff. Two typical particle-size distributions for dyestuff dust are shown in Figure 1. 4 Principle Dust is generated from a dye sample by means of a dust-generating device, extracted from the dust-bearing air by vacuum and conveyed to a detection point, where the amount of dust generated is estimated
36、 visually or determined quantitatively by a gravimetric or photometric method. 5 Apparatus 5.1 Balance, accurate to 0,1g, for weighing out the dye. 5.2 Dust-generating device, with filter holder and connecting joints, and incorporating the following additional components (see Figure 2 and Figure 3).
37、 NOTE 1Instead of a filter and filter holder, other dust-detection devices may be fitted to the apparatus, such as animpactor or an optical particle counter. NOTE 2For information on sources of supply of the dust-generating device and the filter, apply to the organizations listed in clause8 of ISO10
38、5-A01:1994. 5.2.1 Filter, white, diameter (50 2)mm, capable of trapping the dust quantitatively (pore size 5 4m). a) For the gravimetric and photometric methods, made of cellulose nitrate. b) For the visual method, suitable glass-fibre filters can be used. 5.2.2 Vacuum pump, with a suction capacity
39、of at least 20l/min. 5.2.3 Regulator, for adjusting the air flowrate. 5.2.4 Flowmeter, capable of monitoring air flowrate between 10l/min and20l/min. 5.2.5 Timer, for opening the slide valve to start suction, and for timing the period of suction. 5.3 Grey scale for assessing staining, complying with
40、 ISO105-A03. 5.4 Analytical balance, accurate to 0,01mg, for weighing the dust collected on the filter(5.2.1) (gravimetric assessment method), and/or photometer, for extinction measurement of the dust collected and dissolved in a suitable solvent (photometric assessment method). 5.5 Cleaning device,
41、 e.g.brush or vacuum cleaner, for cleaning the apparatus. 5.6 Tweezers, for removing filter paper from holder after dust generation.ENISO105-Z05:1998 2 BSI 04-1999 NOTEThe x-axis of both graphs has a logarithmic scale.

If the
43、gravimetric method of assessment is used, condition and weigh the filter before insertion into the filter holder. Using the balance(5.1), carefully weigh out10g 0,1g of the dye and place it in the hopper at the top of the apparatus. Start the timer(5.2.5) to open the slide valve with a sudden action
44、, allowing the dye to drop down through the tube into the dust chamber below. Five seconds after the slide has opened, apply a vacuum to extract the dust from the chamber for collection on the filter(5.2.1) under the following conditions: air flowrate:15l/min; extraction time:120s (starting5s after
45、dye has dropped); height of fall:(815 5)mm. Using tweezers(5.6), carefully remove the dust-laden filter from the holder and evaluate it by one of methods given in clause7. Clean the equipment thoroughly(5.5) after each test. If the equipment is wet-cleaned, take particular care that it is dried thor
46、oughly. 7 Assessment of filter 7.1 Visual method Compare the dust-laden filter visually with the grey scale for assessing staining(5.3), where Rating1=very dusty and Rating5=no dust. Half-ratings may be used. NOTEIt is also possible to carry out a visual assessment of colourless solid materials. How
47、ever, special care has to be exercised in such cases. Black filters may be helpful, but require separate preliminary trials. It is preferable to use the gravimetric or photometric method. 7.2 Gravimetric method Weigh the dust-laden filter on the analytical balance(5.4). Since with low-dusting produc
48、ts the mass of dust is very small (1mg), considerable errors are to be expected with the gravimetric method. In such cases, preference should be given to photometric measurement. 7.3 Photometric method For photometric measurement of the amount ofdust, dissolve the dyestuff by shaking well the dust-l
49、aden filter in a suitable solvent at room temperature. When a clear solution has formed, measure the transmission with a photometer and read the corresponding amount of dust off a previously prepared calibration graph. NOTEFurther details may be found in the literature. See for example Annex B. Figure 3 Filter holderENISO105-Z05:1998 BSI 04-1999 5 8 Expression of results The generation and detection of dust depend on a great number of parameters. For this reason, the determination of the amount of dus
