ISO Foreword
The International Organization for Standardization (ISO) is a worldwide association of national standardization bodies (member bodies). The work of developing international standards is usually carried out by technical committees. Any member body that is interested in the work established by a technical committee has the right to participate in the work. Governmental and non-governmental international organizations that have relations with ISO may also participate in this work. In the case of technical standardization, ISO also cooperates with the International Technical Products Council (ISOC). The international standard adopted by the technical committee shall be issued to the member bodies for verification. When it is issued as an international standard, it is required to have a minimum of verification fees.

It is the responsibility of the user to establish appropriate safety and environmental measures and ensure compliance with national regulations. 1 Standard
This standard only describes the method for measuring the particle size distribution of nuclear amine particles. This standard is not applicable to the determination of particle size distribution of extremely large particles. 2 Referenced standards
The provisions contained in the following references constitute the provisions of this standard through reference in this standard. When this standard is published, the versions shown are valid. All standard parts are subject to modification. Parties using this standard shall use the following references The possibility of a new version of the standard is shown.

3 Method
The carbon black of the order is passed through test sieves of different sizes and apertures for several times, and the mass of the carbon black retained in each sieve is weighed. The distribution of the carbon black is calculated. ||t t||4 Chemical dew, equipment

5 Sample
Sampling is carried out according to the provisions of GB3778,
6.1 From bottom to top, stack the test sieves in the following order (4,2) No bottom plate 0.1mr250mm.c.5ccm1. wuam.2.o00mm. If .7:m is used to reduce the obstacle, or use the test end that is not specified in 4.2, weigh it in the active position E.2 Pass the sample through the sample divider. Weigh two pieces of the certificate, each weighing (10): 107g, the accuracy rate is 0.1g: E.3 Place the sample in the top of the test sieve, install the test sieve top stem (1.1). And guide the sieve into the mechanical vibrating sieve machine (4.). 6.4 Start the vibrating sieve and vibrate for T*)s.
6.5 Remove the test sieve group from the sieve transfer machine, and transfer each test sieve to the customer device (4.7) at the bottom of the test sieve. Then weigh it and weigh it to the standard of c.1R:
6.G According to steps 6.3--6.5, take a sample and test it. The results are shown in
7.1 Granulation The particle size distribution is expressed as a percentage of mass. Calculate according to formula (1): mx100
Where: "The mass of the carbon in the first test sieve or the receiving tray at the end is the mass of each sample, and the unit is
..- 1?
7.2 All the test sieves or the receiving plate of the bottom of the test shall have the same quality. If the difference exceeds 2%, the test is invalid. 7.3 The test results are collected to the decimal point, and the average is taken. Then, it is rounded to 0.8%.
