IS0 105-B02:1994(E)ForewordIS0 (the International Organization for Standardization) is a worldwidefederation of national standards bodies (IS0 member bodies). The workof preparing International Standards is normally carried out through IS0technical committees.Each member body interested in a subject forwhich a technical committee has been established has the right to berepresented on that committee. International organizations, governmentaland non-governmental, in liaison with ISO, also take part in the work. IS0collaborates closely with the International Electrotechnical Commission(IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees arecirculated to the member bodies for voting. Publication as an InternationalStandard requires approval by at least 75 % of the member bodies castinga vote.International Standard IS0 105-B02 was prepared by Technical CommitteeISOFC 38, Textiles, Subcommittee SC 1, Tests for coloured textiles ethird(IS0 105-B02:1988), of which it constitutes a technical revision.editionThis is a free 5 page sample. Access the full version online.IS0 105 was previously published in 13 “parts”, each designated by aletter (e.g. “Part A”), with publication dates between 1978 and 1985. Eachpart contained a series of “sections”, each designated by the respectivepart letter and by a two-digit serial number (e.g. “Section A01 “). Thesesections are now being republished as separate documents, themselvesdesignated “parts” but retaining their earlier alphanumeric designations.A complete list of these parts is given in IS0 105-AOI .Annexes A and B form an integral part of this part of IS0 105.

The results from the two different sets of references may not be identical.NOTE 1General informationis given in annex C.This is a free 5 page sample.
