冷冻负载试验包/freezing load test package 1kg -1℃
The freezing load test package is made according to ISO15002 /EB15002/ IEC62552, 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.

冷冻负载试验包/freezing load test package 1kg -1℃
名称：冰箱试验包
试验包是放置在冷冻食品储藏室和冰温室内进行性能试验时，或在冷冻冷藏箱内进行冷冻能力试验时，模拟食品的负载。
M包是在几何中心处装有感温元件的试验包。
概述：试验包满足GB/T8059.2及GB/T8059.4标准要求。试验包是放置在冷冻食品储藏室和冰温室内进行性能试验时，或在冷冻冷藏箱内进行冷冻能力试验时，具有直角平行六面体形状的，模拟食品的冷冻负载。
试验包的成分：
1.此填充料的冻结点为-1℃（其热学性能相当于瘦牛肉）。
2. 包装材料为一层塑料薄膜或具有与环境介质进行水汽交换可忽略不计特性的适当材料，装入填充料后，立即将包装材料密封。可采用一种层压薄膜，它是由一层易于封接的120**13211;厚的高压聚乙烯薄膜和外面用一层约12.5**13211;厚的聚对苯二酸酯薄膜粘接在一起的层压薄膜。
3. 测定冰温室时，必须使用冻结点为-5℃的试验包。
此类试验包不能在冷冻能力和负载温度回升时间的测试中使用。
4. “M”包或称测量包，是指质量为500g的试验包，其几何中心处装有供测温用的热电偶，热电偶与填充料直接接触。应采取措施使外界的热传导减至*小。
