Australia Standard AS1731.4-2003 frozen load test package
The freezing load test package is made according to GB/T8059.2 GB/T8059.4, and we can also make the package in different standard according to different requirement.
Test package is placed in the frozen food storage compartment and ice greenhouse performance test, or in a freezer to test the freezing capability test, to simulate the load capacity of frozen food.
1. The freezing point of the test package is -1℃ (Its thermal performance is equivalent to lean beef)
2. Packaging material is a thin layer of plastic, or with appropriate materials which can do medium vapor exchange with the environment, immediately seal the packaging material after filling,
3. When measured in ice greenhouse, must use the -5℃ test package.
4. You cannot use in test of testing freezing capacity and load temperature rise time.
5. M package means the 500g test package, it equipped with a thermocouple in the geometric center to measure the temperature. The thermocouple contact the package directly.
