3、he International Organization for Standardization) is a worldwide fed- eration of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 technical committees. Each member body interested in a subject for which a technical comm
4、ittee 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. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrote
5、chnical 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 IS0 105-205 was prepared
6、by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 1, Tests for co/owed textjles and colorants. IS0 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 d
7、esignated by the re- spective part letter and by a two-digit serial number (e.g. “Section A01 I). These sections are now being republished as separate documents, them- selves designated “parts” but retaining their earlier alphanumeric desig- nations. A complete list of these parts is given in IS0 10

It is import
11、ant 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 IS0 105 is both more representative of and comparable with actual practice when handling dyestuffs. In respect of a comparison of
12、 dyestuffs or the reliability of limits, it should be understood that the result- ing value is not a specific value like density. Details of reproducibility data are given in annex A.

15、cifies a method for determi- nation 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 IS0 105. At the time of publication, the editions indicated were valid. All standards a
16、re subject to revision, and parties to agreements based on this part of IS0 105 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International Stan- dards. IS0 105-AOI : I

18、es of solid material dispersed in a gas. NOTES I Dyestuff dust is formed during handling operations such as dispensing, transferring, sprinkling, etc. 2 Solid dyes are sold in different physical forms (powdered, granulated, etc.). The particle-size distribution of commercial products varies consider
19、ably. The mean particle diameter may be less than 50 pm or as much as several millimetres. The range of the particle-size distribution of a solid dye may also be narrow or wide. 3 The particle-size distribution of dyestuff dust is largely independent of the physical form of the dyestuff. Two typi- c
20、al 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 esti- mated visually o
21、r determined quantitatively by a gravi- metric or photometric method. 5 Apparatus 5.1 Balance, accurate to k 0,l g, for weighing out the dye. 5.2 Dust-generating device, with filter holder and connecting joints, and incorporating the following ad- ditional components (see figures 2 and 3). NOTES 1 I
22、nstead of a filter and filter holder, other dust-detection devices may be fitted to the apparatus, such as an impactor or an optical particle counter. 2 For information on sources of supply of the dust- generating device and the filter, apply to the organizations listed in clause 8 of IS0 105-A01 :I
