This standard is not equivalent to the international standard 159) 1125:1999. The determination of carbon black content is 3. The national standard GT3780.10-2 is about the determination of ash content. The main technical differences between this standard and 1201125:1995 are: First, this method is the general method, and the "national standard" has increased acetylene black and carbon black. The burning temperature specified in GB/T1730.101992 is 5525. In order to improve work efficiency, this standard specifies the burning temperature (3
Color Ya is consistent with GB/T1730.101992 The difference between the two results is not more than 1%. The difference between the two results is not more than 1%. The international standard is G.13-13.
The standard is proposed by the State Chemical Industry Bureau for export. This standard is mainly issued by the National Nuclear Rubber and Rubber Standardization Technical Requirements Committee. This standard is drafted by the China Nuclear Rubber Group Carbon Industry Research and Design Institute. The main drafters of this standard are: the following: Qing. This standard was first revised in December 1881 and June 1882. Cn/T 37B0.102002
ISO Foreword
The International Standards Organization (15) is a global body of national standards bodies (1 member bodies): the work of preparing International Standards is normally carried out through committees: any member body interested in a subject for which a document has been submitted by a committee has the right to be represented on the committee. Governments and non-governmental international organizations associated with (S) also take part in the work. On all matters of electrotechnical standardization, ISO collaborates closely with the International Electrotechnical Commission (IFC). International standards adopted by the technical committees The draft of the international standard should be sent to the market for voting. When it is published as an international standard, it requires at least 75 voting members to vote.

5.1Push the garbage from the house to the room temperature at 25℃, and put it in the artificial dryer. After cooling to room temperature, weigh 0.1m
6.2Dry for 1h in the medium of 27℃. Cool to room temperature. 6.3Put the carbon wing in the city of 2 feet high, and fill it to 0.1m. Near: The average content of 1g of ethylene is 5 5.4 Place i.1 in a high temperature furnace for 25 minutes and weigh until the mass is determined (i.e. the difference between the two weighings is 5.3m): move the sample to a dryer and let it cool to the original temperature. Then weigh it: record the smaller value. Note: After the sample is cooled in the burner, let the gas enter the dryer slowly to avoid the ash content in the gas. The result is expressed as
|The heat storage content is expressed as a fraction of the amount. The formula is used to calculate the mass of the data. g:
