3、72 4 National foreword This British Standard is the English language version of EN ISO 105-Z05:1998. It is identical with ISO 105-Z05:1996. The UK participation in its preparation was entrusted by Technical Committee TCI/25, Chemical properties, to Subcommittee TCI/25/-/10, Colour fastness, which ha
4、s the responsibility to: aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in
5、the UK. A list of organizations represented on this subcommittee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC standards normally include an annex which lists normative references to international publications with their correspondi
6、ng European publications. The British Standards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogu

25、 (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 com
26、mittee 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 electrot
27、echnical 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 least 75 % of the member bodies casting a vote. International Standard ISO 105-Z05 was prepared
28、 by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles and colorants. ISO 105 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 series of “sections”, each
29、 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 is given in ISO 105-A01

Descriptors: Textiles, dyeing, colour fastness, powdery materials, dyes, tests, colour-fastness tests, determination, properties.

32、g 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 ISO 105 is both more representative of and comparable with actual practice when handling dyestuffs. In re
33、spect 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 Annex A. 1 Scope This part of ISO 105 specifies a method for determination of the dusting behaviour of
34、dyes. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 105. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to agreements based on this
35、part of ISO 105 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 International Standards. ISO 105-A01:1994, Textiles Tests for colour fastness Part A01: General principles
36、 of testing. ISO 105-A03:1993, Textiles Tests for colour fastness Part A03: Grey scale for assessing staining. 3 Definition For the purposes of this part of ISO 105, the following definition applies. 3.1 dust particles of solid material dispersed in a gas NOTE 1Dyestuff dust is formed during handlin
37、g 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 varies considerably. The mean particle diameter may be less than 50 4m or as much as several milli
38、metres. 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 dyestuff. Two typical particle-size distributions for dyestuff dust are shown in Figure 1. 4 Princip
39、le 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 visually or determined quantitatively by a gravimetric or photometric method. 5 Apparatus 5.1
40、Balance, accurate to 0,1 g, 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). NOTE 1Instead of a filter and filter holder, other dust-detection devices may be fitted to th
41、e apparatus, such as an impactor 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 clause 8 of ISO 105-A01:1994. 5.2.1 Filter, white, diameter (50 2) mm, capable of trapping the dust quantitat
42、ively (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 of at least 20 l/min. 5.2.3 Regulator, for adjusting the air flowrate. 5.2.4 Flowmeter, ca
43、pable of monitoring air flowrate between 10 l/min and 20 l/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 ISO 105-A03. 5.4 Analytical balance, accurate to 0,01 mg, for weighing the dust colle
44、cted 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, e.g. brush or vacuum cleaner, for cleaning the apparatus. 5.6 Tweezers, for removi

Start the timer (5.2.5) to open the slide valve with a sudden action, allowing the dye to drop down through the t

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: 15 l/min; extraction time: 120 s (starting 5 s after 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 clause 7. Clean the equipment thoroughly (5.5) after each test. If the equipm
