This standard is equivalent to the American Association for Testing and Materials standard ASTM514--1595a poly black standard test method sieve residue to the national standard 1370.71-:99: rubber with micro black end residue delimited water flushing statement modification standard. This standard is slightly different from ASTMDI5110a: (B3778-:094 requirements. This standard is tested in person. The results and accuracy are based on Score coupons: According to the international situation of my country, the adjustment of the water music is 11 (0.2-U.05P:1-month standard G15/8173-1937 number of information is more than the current standard (3/T2782:191 main fee technology: cancel the first day of the cup standard meaning of the English, the chapter enlarges the applicable questions of this standard. - Method your report adopts 43M[1:1-199a, Chapter 1 clearly states the general experimental information instrument equipment various
4.1 increase Intent of filling stomach, "foreign meat wear according to 1\1." The requirements of 6.3 according to A5TMD1=14-95 are passed through the content of the amount, and the commonly used method is increased. 1, the sieve residue is judged by the method of ASTMD15[419a, the chapter \ conclusion shows "to use ATM>15[995 in the form of S14-15 provisions, the yield is U.4% re-compensation is changed to 1%, such as the rate group method.

Continuous decline: Personnel using this standard should be familiar with routine laboratory work. This standard does not involve any safety issues in use. Users are responsible for establishing appropriate safety and health measures and ensuring compliance with national regulations. 1. Scope
This standard specifies the method of measuring glere residue by water flushing method. This standard is applicable to rubber charcoal used in service. Carbon used in other ways can also refer to this standard. 2. Reference standards
The following are the provisions contained in the standard. The provisions promoted by this standard are used in this standard. The editions shown are valid at the time of publication of this standard. All standards will be updated. Parties using this standard shall discuss the possibility of using the following new editions: GR372-1S5 Carbon black for rubber

3 Method Summary
Rinse the carbon in the test section with a standard water flow until the residue on the sieve is non-weak residue. Dry and weigh the mass of the residue on the sieve. The mass of the residue is expressed as the percentage of the residue to the mass of the test sample. 4 Instruments and equipment
4.1 Water-washed sieve residue determination device, as shown in Figure 1. Note: Domestic TY-water-washed sieve residue is the product name of the device supplied by the China Carbon Research Institute. This schedule is given for the purpose of the use of this standard, and the approval of this product by the Chemical Industry Standards Department. 4-2 Test sieve: with phosphorus sound system or non-induction system, in accordance with GBW3. Regulations. 4.3 Water filter, installed on the water supply line of the treasure or net, its aperture and test sieve 4.4 days and a half, the degree is 0.01.
4.5 Analysis rate, the degree is 0.1mg.
1.6 Supply, annual force convection type, can be adjusted to (126 +! Temperature and pressure and viscosity at 15 degrees. The People's Republic of China National Quality Supervision, Inspection and Quarantine General 20020529 approved 2002-12-01 implementation

Model collection
6.1 Set the residual material measurement device to calibrate according to the requirements of the book. 6.2 Open A, E, close (net, as shown in the figure, the filter on the new sewage selection water supply pipeline is close. 6.3 Close the 1 line (chest: when A is fully opened, the valve is adjusted to return water (02) before the specified test port is washed 3 times before the pain of the test device, the test screen is abnormal. There is a new test. When there is foreign matter, the sample is determined by the mutual light. 6.4 transfer glue 10 area carbon black sample state standard U.1k): pour it into the temperature bucket in batches, T open A read the profit chart to select the specified density of the pressure punch, and the group of devices mentioned in the above should be stored in the room to prevent the website from falling. Note: If necessary, the design of the high-speed advance book does not follow the public specification, which can make the water more strong. It is necessary to change the body of the disperser in the month. 5. Use the water in the pipe connected to D to clean the gray and black on the test sieve until the test sieve is rinsed with water.
6. After the test sieve is washed, gently remove the black spots that have not been properly moistened. Do not use excessive force to avoid deformation of the sieve. 5.7 Install the new sieve on the pipe and continue to wash it. 6.3 If the test sieve is still black, repeat steps 6 and 7 until there is no black spot. 5. 9 Remove the two sections of transport" 6-baking flowers and refining
6. Place the teacher's small cold temperature special ten of my things on a flat paper to remove the remaining black on the map, until the black on the paper is no longer visible, the remaining parts of the brush will be a mountain you test the quality of the mountain, the state price big calorie you quantity, strive for 0.1, record the amount of mother m: station
! To ensure the net of various anti-infection years and non-institute materials 5 investment before the control network has a hole in the seam support, so that the back In the production wave water purification method, the green belt net is used for 3-year control to determine whether the flow net is strict and whether it is correct. The center water level filter net is used to control the water level. Instructions for use: The total M pool P is calculated in the AST degree. The result is expressed as GB/T3780.71-7002. The amount of sieve residue is expressed as a percentage of the sieve residue pressure square carbon sample mass, and is calculated according to formula (1): t.||t t||m: a black sample quality station.gi

The single result is one more effective place than the number in GB3778, and the average value is then followed by GB/T8170 for numerical rounding.B Density 1
