Table 1 Simulated cold distribution chain conditions

Conditions	Common conditions			Variable conditions
	Temperature	Total inspection time	Number of inspection	Door opening frequency	Door opening time
A1)	4-5°C	12 h	1 time every 4 h	0	0
B				every 10 m	20 s
C				every 10 m	1 m

A: Conditions in an environment without variables, B: Conditions similar to general distribution environment, C: Worse conditions than the general distribution environment
