Determination of matter volatile at 105 degrees C The European Standard EN IS0 787-2 : 1995 has the status of a British Standard 3s EN IS0 787-2 : 1995 ! National foreword The revision of Part B6 of BS 3483 has been prepare
2、d under the direction of the Pigments, Paints and Varnishes Standards Committee. It is identical with IS0 787/2 General methods of test for pigments and extenders - Part 2 : Determination of matter volatile at 105 OC, published in 1981 by the International Organization for Standardization (ISO). Thi
3、s Part of BS 3483 supersedes BS 3483 : Part B6 : 1974 which is withdrawn. In 1994 the European Committee for StandarMon (CEN) accepted IS0 787-2 : 1981 as European Standard EN IS0 787-2 : 1995. As a consequence of implementing the European Standard this British Standard is renumbered as Bs EN 787-2
4、and any reference to BS 3483 : Pcut B6 should be read as a reference to Bs EN IS0 787-2. Terminology and conventions. The text of the international standard has been approd.as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical
5、 with those used in British Standards; attention is especially drawn to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words This part of IS0 787 and International Standar
6、d appear, referring to this standard, they should be read as This Part of BS 3483 and British Standard respectively.

7、 Additional information. In paragraph 2 of 5.2 of IS0 787/2-1981, it is stated that the whole procedure (clause 5) is to be repeated if the duplicate determinations differ by more than 10 %. In implementing this standard in the United Kingdom, it is recommended that, if repeat determinations are nec
8、essary, wherever possible both the sampling (clause 4) and the procedure (clause 5) should be repeated.* Compliance with a British Standard does not of itself confer immunity from legal obligations. 4$ This change has been reported to the IS0 in a proposal to amend the text of the international stan

Take a representative sample of the material to be tested as described in IS0 842. 1 Scope and field of application 5 Procedure Carry out the determination in duplicate. 5.1 Test portion This part of IS0 787 s
19、pecifies a general method of test for determining the percentage by mass of matter volatile at a temperature of 105 OC in a sample of pigment or extender. This method is applicable to pigments and extenders that are stable at 105 OC (but see also the note to 5.2). NOTE - When this general method is
20、applicable to a given pigment or extender, only a cross-reference to it should be included in the Intema- tional Standard relating to that pigment or extender, with a note of any detailed modification which may be needed in view of the special pro- perties of the material in question. Only when this
21、 general method is not applicable to a particular material should a special method for determination of volatile matter be specified. 2 Reference Heat the weighing bottle (3.11, with the stopper removed, in the oven (3.2) at 105 OC for 2 h. Allow to cool in the desiccator (3.41, insert the stopper a
22、nd weigh to the nearest 1 mg. Spread 10 f 1 g of the sample in a uniform layer on the bot- tom of the weighing bottle, insert the stopper and weigh to the nearest 1 mg. NOTE - It may be necessary to reduce the mass of the test portion for pigments and extenders with a high bulk volume. The use of a
23、test por- tion smaller than that specifd should be stated in the test report. 5.2 Determination ! Is0 842, Raw m ml is the mass, in grams, of the residue. Calculate the mean of the two determinations, if they do not differ by more than 10 % of the higher value, and report the resutt to the nearest 0
