Test method for measuring the cumulate clean mass (CCM) of particulate matter in 3m³ air purifier performance CCM test chamber
1. Scope of 3m³ air purifier performance CCM test chamber
The test method for evaluating the cumulate clean mass (CCM) of the cleaner for the particulates.
The cumulate clean mass (CCM) for the particulates shall be evaluated by the accelerated test method. The accelerated test is performed in 3m3 air purifier performance CCM test chamber.
It is only applicable to the test for the cumulate clean mass of the cleaner for which the clean air delivery rate (CADR) for the particulates is not less than 60 m3/h.
2.Test steps of 3m3 air purifier performance CCM test chamber
Perform the cumulate clean mass for the particulates according to the following steps:
a) Test the clean air delivery rate of the particulate for the cleaner, and determine its initial value;
b) Light up and introduce a single cigarette in 3m3 air purifier performance CCM test chamber, turn on the stirring fan for 0 minutes, then turn off the stirring fan for standing for 10 minutes, measure and record the effective generation volume of the particulates from the single cigarette;
Note: If the cigarette lighting device is capable of containing multiple cigarettes, the total effective generation volume of the particulates from the cigarettes shall be measured.
c) Place the cleaner into 3m3 air purifier performance CCM test chamber, turn on the cleaner and adjust it to the rated condition, turn on the stirring fan, and close the door of the test chamber;
d) Continuously light up and introduce 50 cigarettes into 3m3 air purifier performance CCM test chamber, turn off the cleaner after the particulate concentration to be monitored is reduced to below 0.035 mg/m3, make the cleaner to stand for at least 30 minutes, and take out the cleaner;
e) Repeat the steps a) ~ d) to respectively obtain the measured values of the cigarette clean air delivery rate for 50 cigarettes, 100 cigarettes, 150 cigarettes, 200 cigarettes, 250 cigarettes... When the measured clean air delivery rate is less than or equal to 50% of the initial value, the test is ended.
The above is the test method for measuring the cumulate clean mass (CCM) of particulate matter with the 3m³ air purifier performance CCM test chamber. If you have any questions, please consult the relevant technical personnel of "Huanyi Instrument".
