9684- 1988 sanitary standard for stainless steel tableware containers, GB/t11681-kloc-0/989 analytical method for sanitary standard for stainless steel tableware containers, etc. These standards clearly include the thermal insulation capacity of glass respectively.
Thermal insulation efficiency, smell, impact resistance, capacity, toppling test, connection fastness between handle and bail, hot water leakage, assembly safety and identification items, and thermal insulation efficiency, capacity, impact resistance of stainless steel vacuum thermal insulation container,
Smell, hot water resistance of rubber parts, installation fastness of handle, sealing, sanitary requirements of stainless steel liner (lead and cadmium), fitting degree of cork, and identification items.
1. Thermal insulation efficiency: Thermal insulation efficiency is the core index of thermal insulation containers.
2. Capacity: On the one hand, the capacity of the heat preservation container can hold enough articles, on the other hand, it is directly related to the heat preservation, that is, the same caliber. The larger the capacity, the higher the required temperature maintenance. Therefore, the positive and negative deviation of the heat preservation container capacity should not be too large.
Third, hot water leakage: the quality of hot water bottles is related to the safety of use and affects the beauty of the use environment. To test the quality of the thermos cup, just lift the thermos cup filled with water. If hot water leaks between the cup liner and the cup shell, whether it is big or small, it means that the quality of the cup can't pass.
Impact resistance: the quality of the thermos cup directly affects the service life of the thermos cup. In the use of the product, it is inevitable that there will be bumps. If the material used for product accessories has poor shock absorption or the precision of accessories is not enough, the bottle will be damaged.
Moreover, shaking and bumping in use may cause the displacement of asbestos pad and the cracking of small tail, which will affect the thermal insulation performance of the product, and even cause the bottle liner to crack or even be damaged in serious cases.
Verb (abbreviation of verb) recognition: Regular thermos cups have relevant national standards, that is, the product name, capacity, caliber, manufacturer's name and address, adopted standard number, use method and precautions are clearly marked.
The above five points are the general standards for quality inspection of insulated containers at present.
