GB/T 8170 Numerical Rounding Rules and Representation and Determination of Limit Values
3 Principle
The sample is extracted with diethyl ether in a Soxhlet extractor, and then the extraction solvent is evaporated to obtain the residual grease quality, thereby calculating the fat
The percentage of dry mass to the dry mass of the sample.
4 instruments, reagents and materials
4.1 Test equipment
a) Soxhlet extractor. the distillation flask is 150mL;
b) Analytical balance. the graduation value is 0.1 mg;
c) a constant temperature water bath;
d) Constant temperature oven. can maintain the temperature (105 ± 3) ° C;
e) dryer. equipped with discolored silica gel;
f) Weigh the bottle.
4.2 Reagents and materials
a) diethyl ether (analytical grade);
b) Qualitative filter paper.
WARNING - Use the solvents specified in this standard and read the MSDS.
5 sampling
5.1 Specimens shall be of the same batch number, same specification and same variety.
5.2 If the sample is for silk silk or crepe spinning, take 2 samples and weigh (3.0±0.3) g each; if the sample is silkworm silk, it will be from each
Batch 2 take the wire barrel (twist), peel off the surface layer, take 2 samples, each (5.0 ± 0.5) g. The two samples taken were labeled with a serial number.
5.3 Each batch of silk cotton, silk spinning raw material or silkworm silk thread shall take one spare sample of the same quality (5.2).
