Annotate: atmospheric pressure should be within 96kPa ± 10kPa.Atmospheric pressure should be tested and be embodied in the test report.
1.1.2 the adjusting time
Under forced draft, the cigar balance needs 72 hours at least.
1.1.3 the check of balance
Meet the cigar sample of one of following condition, be considered to obtain balance:
A) in 24 h, the quality of cigar relatively variation is not more than 0.1%;
B) in cigar is placed on the closed container suitable with its volume, the relative humidity in this container is identical with the relative humidity of the Gas regulation of regulation.
1.2 cigarette mark
The cigar of mouth end sealing should excise mouth end 5 mm, and mark lengths does not comprise the part of excision.
Carry out mark with a soft head insertion depth (apart from cigar holder end 28 mm places) to cigar, be accurate to 0.5 mm.
Should avoid damaging cigarette during mark.The cigarette of accidental damage or labeling process find that defective cigarette should discard, and replace with cigarette for subsequent use.
The selection of cigar measuring head
When carrying out the cigar analysis, need to be according to the concrete suitable measuring head of apparent parameter assembling of cigar.Select emulsion tube sleeve, emulsion tube and sealing gasket in measuring head base and the measuring head according to cigar apart from the diameter at mouth end 15 mm places.As shown in Figure 1, the cigar measuring head comprises that the two large divisions forms: measuring head base portion and cigarette retained part.Figure 2 shows that measuring head base schematic diagram, as shown in Figure 2, the measuring head base only has two kinds of models to select, the difference of these two kinds of models is that the diameter with cigarette retained part junction is 26mm or 32mm, and the base of these two kinds of models is applicable to respectively the cigar that diameter range is 6.5 mm-16.49 mm and 16.5 mm-22.5 mm.Figure 3 shows that the part that is used for the cigarette clamping in the cigar measuring head.Because the size of cigar differs, therefore need according to the diameter of cigar emulsion tube sleeve and emulsion tube in the measuring head to be selected according to table 1, sealing gasket is selected according to cigar holder end shape by the operator, should avoid the fold of cigar, leaks gas in the test process preventing.The measuring head of standard should coat cigarette 28 mm from the cigar holder end, and flue gas composition and air are all had impenetrability, avoids leaking gas between cigar and the measuring head.
The setting of air flow rate
Be 11.8 cm/s in order to keep the gas velocity by the cigar xsect, diameter greater than the air flow rate of 12.0 mm cigars should according to cigar be obtained apart from the diameter at mouth end 33 mm places.Air flow rate is tried to achieve according to the diameter according to the form below 2. of cigar:
