The method is used to detect volatile components. NOTE The users of the method are encouraged to gather comparative informatio
21、n on binders using this standard, EN 13303 and EN 12607-2 1 at 163 C to facilitate the withdrawal of EN 13303 at the next systematic review. WARNING The use of this standard may involve hazardous materials, operations and equipment. This standard does not purport to address all of the safety problem
22、s associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 2 Normative references The following referenced documents are indispensable for the applica

25、ssed as a percentage of the latter 4 Principle A weighed sample is heated for a specified time at a specified temperature and is re-weighed at the conclusion of the heating period. 5 Apparatus 5.1 Oven, electrically heated and conforming to the performance requirements for ovens ventilated by natura
26、l convection and for operating temperatures up to 180 C. The oven shall be rectangular with minimum interior dimensions of 330 mm in each direction. The oven shall have in front a tightly fitting hinged door, which shall provide a clear opening, substantially the same as the interior height and widt
27、h of the oven. The door may contain a window with dimensions of at least 100 mm x 100 mm, and with two sheets of glass separated by an air space, through which a vertical thermometer (5.3) located as specified in 7.8, may be read without opening the door, or the oven may be provided with an inner gl
28、ass door through which the thermometer may be observed on opening the outer door momentarily.

29、vection currents of air and for this purpose shall be provided with openings for the entrance of ambient air and egress of heated air and vapours. These openings may be of any size and arrangement provided the temperature requirements of the test are met. 5.2 Rotating shelf (see Figure 1a and 1b) Th
30、e oven shall be provided with a circular metal shelf having a minimum nominal diameter of 250 mm. The shelf shall be suspended by a vertical shaft and centred with respect to the horizontal interior dimensions. The shelf shall be provided with a mechanical means of rotating it at the rate of 5 rpm t
31、o 6 rpm. The shelf shall be vertically located as close to the centre of the oven as permitted by compliance with the requirements of the procedure regarding thermometer placement.

Therefore any alternative device employed shall be calibrated so as to provide the same readings as would be provided by the mercury stem thermometer, recognising and allowing for the fact of changed th
35、ermal response times compared with the mercury thermometer. 5.4 Test sample container, metal or glass, cylindrical in shape, and with a flat bottom. The inside dimensions shall be approximately: diameter, 55 mm and depth, 35 mm i.e. conforming to the dimensions of the container specified in EN 1426
36、for penetration lower than 160 x 0,1 mm. 5.5 Balance, with a reading accuracy of 0,01 g. 6 Sampling The material under test shall be sampled in accordance with EN 58 and prepared in accordance with EN 12594. 7 Procedure 7.1 Weigh the container (5.4) and record the mass, mc, to the nearest 0,01 g rea
37、ding. 7.2 Place 50,0 g 0,5 g of the sample of the material to be tested in the container. Weigh the container and the sample, and record the mass, m1, to the nearest 0,01 reading. Carry out the test on duplicate samples. 7.3 If the sample has been heated to facilitate its transfer, cool the containe
38、r and sample to ambient temperature before making the initial weighing (see sub-clause 7.2).

39、.5 Place the container with the weighed sample on the circular shelf into one of the recesses. 7.6 Close the oven and rotate the shelf for the duration of the test at a rate of 5 rpm to 6 rpm. 7.7 Maintain the oven temperature at (163 1) C for 5 h after the samples have been introduced. The 5 h peri
40、od commences when the temperature reaches 162 C, and ensure that, in no case, the total time that a sample is in the oven exceeds 5 h and 15 min. 7.8 Determine the oven temperature by means of the specified thermometer (5.3), which is placed in a vertical position approximately 19 mm inside the peri
41、meter of the shelf, and with the bottom of the thermometer bulb 6 mm above the shelf. If an electrical thermometer is used it should be placed parallel to the shaft in the same position as before but not rotated. 7.9 At the conclusion of the heating period, remove the sample from the oven. 7.10 Cool
42、 the sample to room temperature under a cover protecting it from dust (e.g. dessiccator). 7.11 Weigh the container and the sample. Record the mass, m2, to the nearest 0,01 g reading. 7.12 It is permissible to carry out multiple tests simultaneously. 8 Calculation The loss in mass after heating of th
43、e test sample is expressed as a percentage, calculated by means of the following equation: c1 21 mm mm 100heating aftermass inLoss = (1) where mC is the mass of the container, in grams (see sub-clause 7.1); m1 is the mass of the container and sample before heating, in grams (see sub-clause 7.2); m2
44、is the mass of the container and sample after heating, in grams (see sub-clause 7.11). 9 Expression of results Express the result as the mean of two results, in percentage. 10 Precision 10.1 Repeatability The difference between two successive results, obtained by the same operator with the same appa
45、ratus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, differ by more than the value given in Table 1 in only one case in twenty.
