27、c) BSI ISO -03642:1)E(400 iv ISO 4002 All rithgs reresvde 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 committe
28、es. Each member body interested in a subject 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 Inte
29、rnational Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International S
30、tandards 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. Attention is drawn to the possibility that some of the elements of this document may be the su
31、bject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 4630-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 10, Test methods for binders for paints and varnishes, in collaboration with ASTM D 01.34, Naval st
32、ores. It has been harmonized with ASTM D 1544-98, Standard Test Method for Color of Transparent Liquids (Gardner Color Scale). It cancels and replaces ISO 4630:1997, which has been technically revised. The main changes are that the chromaticity coordinates and luminous transmittances are now used as
33、 reference standards instead of liquid standards and that the conversion procedure for glass test tubes having an inside diameter other than (10,650,025) mm has been deleted.

35、Gardner colour scale Part 1: Visual method 1Scope This part of ISO 4630 specifies a method for estimating, by means of the Gardner colour scale, the colour of clear, yellow/brown liquid products using colour-measuring instruments. The results might be invalid if other products are tested. It is appl
36、icable to drying oils, varnishes and solutions of fatty acids, polymerized fatty acids, resins, tall oil, tall oil fatty acids, rosin and related products. It is applicable to products having colours from Gardner 1 to Gardner 18. The Gardner scale is not applicable to products with colours lighter t
37、han 1 or darker than 18. 2Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IS

42、ne-third of the difference in or (see Table 1) between adjacent reference standards. In any one set of working standards, no two standards shall be closer together than two-thirds of the difference in or between the corresponding reference standards. The luminous transmittance shall be as specified
43、in Table 1. In cases of dispute, only reference standards (4.1.1) shall be used. The standards shall be mounted in such a way that they can be conveniently handled and allow simultaneous viewing of two adjacent standards in the colour comparator (4.3). When using liquid working standards coloured so
44、lutions contained in glass tubes (4.2) they shall be checked by the method specified in Annex A. Potassium hexachloroplatinate(IV) solutions are used for the lighter standards (1 to 8), and solutions of iron(III) chloride and cobalt(II) chloride in hydrochloric acid are used for the darker standards
