Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). T
15、he work of preparing International Standards is normally carried out through ISO technical committees. 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-go
16、vernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International 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 3.
17、 The main task of technical committees is to prepare International Standards. 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 v
18、ote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: ?an ISO Publicly Available Specification (ISO/PAS) represents an agreement between technical experts in an ISO worki
19、ng group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; ?an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publication if it is approved by 2/3 o
20、f the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed every three years with a view to deciding whether it can be transformed into an International Standard. Attention is drawn to the possibility that some of the elements of ISO/TS 14423 may be the subject of patent rights.
21、 ISO shall not be held responsible for identifying any or all such patent rights. ISO/TS 14423 was prepared by Technical Committee ISO/TC 47,Chemistry, Subcommittee SC 7,Aluminium oxide, cryolite, aluminium fluoride, sodium fluoride, carbonaceous products for the aluminium industry.

The most
23、practicable way to achieve this is by extraction of the binder by a suitable solvent, and the most effective common solvent for coal-tar and bituminous binders is quinoline. Most coal tars are not totally soluble in quinoline, but have a small content of insoluble matter which principally comprises
24、infusible solid carbonaceous particles smaller than approximately 50 ?m. This insoluble matter is effectively part of the solid aggregate of the cold-ramming paste and is measured as such by this method. The effective binder is defined as that proportion of the product which is soluble in quinoline.
