3、reword This British Standard is the English language version of EN ISO 584:1997. It is identical with ISO 584:1982. The UK participation in its preparation was entrusted to Technical Committee PRI/42, Fibre reinforced thermosetting plastics and prepegs, which has the responsibility to: aid enquirers
4、 to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep the UK interests informed; monitor related international and European developments and promulgate them in the UK. A list of organizations repres
5、ented on this committee can be obtained on request to its secretary. Cross-references Attention is drawn to the fact that CEN and CENELEC Standards normally include an annex which lists normative references to international publications with their corresponding European publications. The British Sta
6、ndards which implement these international or European publications may be found in the BSI Standards Catalogue under the section entitled “International Standards Correspondence Index”, or by using the “Find” facility of the BSI Standards Electronic Catalogue. A British Standard does not purport to
7、 include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover,

27、BSI EN ISO 584:1997 BSI 03-19991 0 Introduction The processing of unsaturated polyester resins depends on their reactivity, i.e., their rate of polymerization in the presence of a catalyst. The evaluation of their reactivity can be carried out by various methods. This International Standard is limit
28、ed to measuring certain characteristics relating to the change in temperature as a function of time of a resin-catalyst mix. Using arbitrarily standardized test conditions, these characteristics allow comparison of similar types of unsaturated polyester resins. The results obtained in this test are
29、dependent upon the following test conditions: a) quantity and spatial parameters of the test portion examined (test-tube diameter, height of resin in the tube); b) speed of heating the test portion placed in a temperature controlled bath. For example, the replacement of water in the bath by another
30、fluid with a lower heat capacity (glycol, oil, etc.) leads to slower heating; c) type of temperature measuring element placed in the test portion and its ability to respond to rapid changes in temperature. Thermometers with a slow response and thermocouples with large junctions between the resistanc
31、e leads are unsatisfactory; d) accurate centring of the thermocouple in the test portion, both in height and in line with the axis. These conditions which are mandatory are specified in the text of this International Standard. 1 Scope and field of application This International Standard specifies a
32、method for the determination of the reactivity of unsaturated polyester resins as characterized by the maximum temperature reached by a solution of unsaturated polyester resin and catalyst when heated in a water-bath at 80 C, by the time taken for the temperature of the mixture to rise from 65 C to
33、this maximum temperature, and also, if the maximum temperature exceeds 90 C, by the time taken for the temperature to rise from 65 to 90 C. These characteristics give an indication of the processing behaviour of unsaturated polyester resins and can be used to compare resins of similar type. As the t
34、est results depend very much on the conditions under which the test is carried out, these conditions are described in detail. NOTE 1If the method is used to test commercial benzoyl peroxide catalyst, the results should be compared with those obtained for the same resin using pure benzoyl peroxide. N
35、OTE 2By agreement between the interested parties, certain test conditions can be modified: such as the test temperature (temperature of the thermostatically controlled bath) and the quantity and type of catalyst system (mixtures of catalysts, combinations of catalysts and accelerators). 2 Principle
36、Placing of a mixture of 100 parts of resin with 1 part of catalyst in a test-tube of defined size. Heating of the test-tube and its contents in a water-bath at 80 C for the duration of the reaction, and noting (or recording) the rise in temperature with time. 3 Reagent During the analysis, use only
37、reagents of recognized analytical grade. Benzoyl peroxide, catalyst. WARNING Attention is drawn to the dangers involved in handling pure benzoyl peroxide. A mixture of 50 % (m/m) of benzoyl peroxide catalyst in dibutyl phthalate having an active oxygen content between 3,25 and 3,33 % (m/m), as measu
38、red by known analytical methods. 4 Apparatus 4.1 Water-bath,1) maintained at 80 0,5 C and provided with a thermostat and a circulation pump or stirrer. 4.2 Test-tube, of borosilicate glass or any other glass giving the same results, of internal diameter 18 1 mm, length 210 5 mm and wall thickness 1
39、0,2 mm. 4.3 Iron-constantan thermocouple, consisting of wires of 1 0,05 mm thickness, with a welded junction of 2 mm diameter maximum and a meter for measuring temperatures up to 250 C, graduated in divisions of 2 C. NOTEIt is desirable to use screened thermocouples that can be positioned centrally.
40、 4.4 If available a recorder, permitting the readings of temperature on the graph paper to the nearest 1 C and the time to the nearest 15 s. 4.5 Device, for locating the thermocouple centrally in the test-tube (see the Figure). 4.6 Balance, accurate to 0,01 g. 4.7 Stop watch. 1) The water in the bat
41、h may be replaced by another fluid agreed upon by the interested parties.

42、3) into a glass beaker of capacity 250 ml and add 100 1 g of resin at a temperature between 15 and 30 C. Continue stirring for 2 to 3 min. 5.2 Then immediately pour part of the mixture into the test-tube (4.2) to a height of 7 to 8 cm. Introduce the thermocouple into the mixture in a position on the
43、 axis of the tube and equidistant from the bottom and the surface of the mixture (see the Figure). Then place the tube in the water-bath at 80 0,5 C, so that the surface of the resin is well beneath the level of the surface of the water. 5.3 If a recorder is used, start and allow the recorder to run
44、 during the complete reaction. Alternatively, note the maximum temperature reached, as well as the time taken for the temperature of the mixture, determined by the thermocouple, to rise from 65 C to the maximum temperature, and in the case where this temperature is greater than 90 C, the time to ris
45、e from 65 to 90 C. 5.4 Repeat the test, beginning at 5.1, until two consecutive determinations do not differ by more than 5 C in temperature and 10 % in time. 6 Test report The test report shall include the following information: a) a reference to this International Standard; b) a complete identific
46、ation of the resin tested; c) the type of thermocouple used and whether screened or unscreened; d) the individual values of the maximum temperature reached in the two tests and the average value; e) the individual values of the time taken for the temperature to rise from 65 C to the maximum temperat
47、ure in the two tests and the average value; f) if the maximum temperature is above 90 C, the individual values of the time taken for the temperature to rise from 65 to 90 C in the two tests and the average value; g) if a recorder is used, the graphs giving the temperature plotted against time. h) an
48、y deviations from the standard test conditions specified in this International Standard, for example type and temperature of the heating medium, catalyst system used, thermocouple system used, etc. (see note 2 to clause 1).
