10、BS ISO 12013-1:2012ISO 12013-1:2012(E)ForewordISO (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
11、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 International Electrotech
12、nical 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 Standards adopted by the
13、 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 subject of patent rights.
14、ISO shall not be held responsible for identifying any or all such patent rights.ISO 12013-1 was prepared by Technical Committee ISO/TC 35, Paints and varnishes, Subcommittee SC 9, General test methods for paints and varnishes.ISO 12013 consists of the following parts, under the general title Paints
15、and varnishes Determination of curing characteristics using a free damped oscillation method: Part 1: Start temperature of the curing reaction Part 2: Glass transition temperatureiv ISO 2012 All rights reservedBS ISO 12013-1:2012ISO 12013-1:2012(E)IntroductionA freshly applied coating dries and/or c
16、ures depending on its physical and chemical characteristics. There are “wet characteristics” of various substrates and the evaporation of the solvent in the drying/or curing process. The structure of the coating changes according to the drying or curing process of the coating. The start temperature
17、of reaction is very important. It is essential to consider the evaporation of the solvent in the measurement of the start temperature of reaction.a) While a solvent evaporates, the curing of the coating begins. The evaporation of the solvent depends on:1) the evaporation behaviour of the solvents;2)
18、 the behaviour of the solvents in the coating film during each drying stage. This is affected by the boiling point.b) The evaporation characteristic of the solvents depends on the solubility and the thermal conductivity of the substrate.
