EN 1007-1:2002 (E) 4 1 Scope This part of EN 1007 specifies the conditions for determination of the size content of ceramic fibres, including among others silicon carbide, silicon nitride, silicon carbonitride, alumino-silicate, alumina and silicon oxide fibr
25、es. NOTECarbon fibres are not covered by this European Standard. EN ISO 10548 should be used for carbon fibres. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places
26、 in the text, and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referr
27、ed to applies (including amendments). EN ISO 291, Plastics - Standard atmospheres for conditioning and testing (ISO 291:1997). 3 Terms and definitions For the purposes of this European Standard, the following terms and definitions apply. 3.1 size materials applied to the ceramic fibres to facilitate
28、 the handling and use of the fibre 3.2 size content the mass of the size expressed as a percentage of the original mass of the sized ceramic fibre in the conditioned state 3.3 elementary unit the smallest commercially available unit of a given product NOTEFor fibre, usually this is a spool. 4 Princi
29、ple Weighing of test specimens before and after removal of size, according to conditions and specified method of solvent extraction. The solvent chosen is dependent on size type and is usually indicated by the manufacturer of the fibre. 5 Apparatus and chemicals 5.1Balance, accurate to 0,1 mg. 5.2Ov
30、en, for drying specimens, capable of being controlled at the chosen temperature 5 C. 5.3Desiccator, containing a suitable desiccant (for example, silica gel, calcium chloride, phosphorus pentoxide). 5.4Thimble, typically 25 mm in diameter and 65 mm in height. 5.5Rubber gloves or tweezers.

32、5 5.6Cutting blade. 5.7Reflux extractor with condenser. 5.8Heating device, such as a water bath, hot plate or isomantle, controllable to the required temperature. 5.9Boiling flask. 5.10Organic solvent, such as 2-butanone (methylethylketone), tetrahydrofuran, dimethylformamide, dichloromethane (methy
33、lene chloride), acetone, dichloroethane or distilled water, as a function of the size type. WARNING: Extraction and handling of organic solvents must be done under fume extraction. 6 Test specimen At least three test specimens shall be taken at random from each elementary unit. The minimum mass of t
34、he test specimen is 2 g. Care shall be taken to handle the specimen only with gloved hands or tweezers. 7 Conditioning of test specimens prior to weighing Storage of the test specimens shall be in one of the atmospheres specified in EN ISO 291. Any drying procedure of the sized fibre prior to weighi
35、ng shall be agreed between supplier and customer. NOTEFor example, (105 5) C, 1 h. 8 Procedure 8.1Dry the thimble for 1 h at (105 5) C. Weigh the dried thimble, M2 and the test specimen of conditioned fibre, M1. Put the test specimen in the thimble. Fill the boiling flask with a suitable solvent. Ad
36、just the volume of solvent to ensure there is sufficient to fill the reflux system. 8.2Put the thimble, containing the test specimen, into extractor with a condensor and fix the whole to the boiling flask. Adjust the rate of refluxing to 5 cycles/h and the number of hours of reflux to ensure that co
37、mplete extraction of the size is achieved. Remove the thimble immediately after the last refluxing. NOTETo ensure that complete extraction is achieved, usually preliminary trial runs with different extracting periods are performed. 8.3Dry the thimble with the desized test specimen during one hour in
38、 the oven set at a temperature of (110 5) C. Put the thimble and the test specimen in a desiccator and allow to cool down, then weigh the whole to within 0,1 mg. If the solvent used has a boiling point above 100 C, set the temperature of the oven at a value 10 C higher than the boiling point of the
39、solvent. 8.4Run again operations described in 8.3 until the difference in weight of two successive weighings is lower than 0,2 mg. M3 is the final weight.

41、M MMM SCi where SCiis the size content expressed in percent (%), and i = 1, 2, 3; M1is the weight of the dried test specimen, expressed in gram (g); M2is the weight of the dried thimble, expressed in gram (g); M3is the weight of the dried thimble plus the desized test specimen, expressed in gram (g)
42、. The size content SC expressed in percent is the arithmetic mean of the above three results. 10 Test report The test report shall contain at least the following information: a) the name and address of the testing establishment; b) the date of the test, unique identification of report and of each pa

44、erature, duration; f) the size content (SC); g) comments about the test or test results.
