YC/T 461 Routine analytical cigar smoking machine Definitions and standard conditions YC/T 463 cigars by conventional analytical determination of total particulate matter and tar with a cigar smoking machine

3 Terms and Definitions

The following terms and definitions apply to this document.

Gas was vapourphase

Conventional analysis conforming YC/T 463 requirements with cigar smoking machine, press YC/T 461 pumping process by cigar smoke Flue part trap.

Principle 4

According to YC/T 463 suction cigar collecting mainstream smoke gas phase composition. Use a calibrated non-scattering infrared analyzer that Gas was collected carbon monoxide was calculated cigar mainstream smoke of carbon monoxide.

5 Equipment

Common laboratory equipment and items specified below.

5.1 Routine analytical cigar smoking machine and accessories, in line with YC/T 461 requirements.

5.2 vapor collection system to meet the following conditions.

a) collection system should not interfere with normal operation of the smoking machine and the total particulate matter, measured smoke nicotine.

b) the use of carbon monoxide at a concentration of 5% (volume fraction) [4% to 6% (volume fraction)] of the gas collection system to check for gas Phase impermeability. The carbon monoxide gas into the gas collecting apparatus previously evacuated, immediately measured concentration of carbon monoxide.

Changes in the concentration of carbon monoxide less than 3h no more than 0.3% (volume fraction).

c) Reference smoking conditions to select the appropriate bag, gas volume collected depends on the diameter of the cigar and suction capacity, the capacity of the bag Phase volume of at least the sum of the volumes of the suction and cleaning, but not more than twice the sum.

5.3 non-scattering infrared analyzer to meet the following conditions.
