GB/T16447—1996 Atmospheric environment for conditioning and testing of tobacco and tobacco products 3 Terms and definitions
The following terms and definitions apply to this standard. 3.1
Filling value of stem The volume occupied by the expanded stem of cigarette under the continuous action of a certain time and a certain pressure per unit mass. 4 Principle
Put a certain mass of expanded stem in a measuring barrel and measure the volume maintained by the expanded stem under the action of a certain time and a certain pressure. 5 Instruments and equipment
The expanded stem filling value measuring instrument should meet the following conditions: 5.1
a) Measuring barrel: cylindrical, with smooth and clean inner wall. Inner diameter 60.0mm±0.1mm, height not less than 100mm. b) Force probe: smooth and clean surface, able to produce a uniform pressure of 9.80N±0.10N on the sample, probe diameter 55.0mm±0.1mm.
Pressure speed: 19.5mm/s±0.5mm/s. c)
d) Filling value sensor: can accurately measure the sample column height, accurate to 0.01mm; display filling value accurate to 0.01mL/g. e) Time controller: time control accuracy is ±0.5s resolution 1s, and can meet the requirements of 30.0s±0.2s. 5.2 Balance: sensitivity is 0.01g.
5.3 Standard gauge block: height is 20.0mm, height accurate to 0.01mm. 6 Sample collection and sample processing
6.1 Sampling point: at the outlet of expanded stem silk air selection. 6.2 The sample for each test shall not be less than 500g. Before testing, the moisture content of the sample should be adjusted according to (GB/T16447, so that the moisture content of the sample reaches 12.5%±0.5%.
6.3 Spread the laboratory sample with adjusted moisture content into a square of about 30cmX30cm, divide the sample into four parts along the diagonal of the square, take two of them, and then take half of them as samples according to the above method. 7 Measurement steps
The measurement environment conditions should meet the requirements of GB/T16447. 1www.bzxz.net
YC/T163—2003
Turn on the instrument power, calibrate the instrument, and zero it. 7.1
7.2 Set the probe force application time to 30.0s by pressing the button, set the number of tests to 10, and then perform zero calibration. 7.3 Take a sample, weigh 10.0g of the test material, the error range is not more than 0.02g, And place the sample in the measuring barrel. 7.4 Press the test button to drive the force probe, so that the sample is subjected to a uniform pressure of 9.80N ± 0.10N. 5 Repeat steps 7.3 to 7.4 for a total of ten tests. 7.5
7.6 The filling value of the sample after pressure is directly recorded on the filling value sensor display, or the measurement result is directly printed. 8
Result representation
The average filling value and coefficient of variation of the expanded stem shreds tested ten times can be recorded on the display of the expanded stem shreds filling instrument. 9
Test report
The test report should include the following:
-The number of this standard;
The mark and description of the sample;
-Measurement time, instrument and model used; Environmental conditions for measurement;
The moisture content of the sample;
-The average value and coefficient of variation of the measurement results.
