Foreword
This standard non-equivalently adopts Japanese Industrial Standard JIS S 2053-1994 Stainless steel insulation vessel.
In addition to the portable stainless steel insulation vessel, this standard adds desktop insulation vessel, big-mouth insulation vessel, and insulation cup.
The small-mouth insulation vessel of which the capacity is lower than 0.4L, the big-mouth insulation vessel, and insulation cup are mainly used to store drinks and food. They will not maintain for a long time under normal using circumstances, so the temperature measurement time for insulation vessel of which the capacity is lower than 0.4L is 12h; the temperature measurement time for big-mouth insulation vessel and insulation cup is 6h. The portable insulation vessel must do tightness test.
This standard specifies that the strap-type insulation vessel shall do swing impact test, the others shall do fall impact test.
Taking the usage characteristics of the products into account, this standard has strict rules on the hygiene requirements of materials of plastics parts and stainless steel liner. The thickness of the material is not specified.
The strap color fastness test in this standard adopts the requirements of GB 3922-1983 the textile?€?s color fastness to perspiration test method.
Taking the characteristics of small volume, heavy weight of the stainless steel insulation vessels into account, the stacking height must not exceed 3.0m.
Tightness performance test method; impact resistance test method; fitness test of the cork installation; mounting strength test of the strap and handle; smell of the water in capacity, cork and the container; and coating adhesion test specified in this standard ADOPT the relevant provisions of JIS S 2053-1994 stainless steel insulation vessel. This standard was proposed by the China Light Industry Association?€?s Quality Standard Department.
This standard shall be centralized by the National Daily Glass Enamel Standardization Center.
Drafting organizations of this standard. China Light Industry Association?€?s Glass Enamel Institute, Shanghai Insulation Vessel Company, Hubei Jingjiang Ltd., Hebei Kaiyuan Industrial Co., Ltd., and Guangzhou Insulation Vessel Industrial Company. The main drafter of this standard. Zhang Guoxiu, Pan Fengfang, Sun Zhongrong, Cui Renquan, and Chen Yumei.
This standard was first-time issued on December 4, 1997.

obvious zigzag, deflated sub, wrinkles, rust and other defects. Welds are smooth without welding tumor.
5.3 Plastic parts shall be processed well. Plasticizing is uniform, with smooth surface, uniform color, no serious rub hair, no inadequate molding and other obvious defects. 5.4 Strap and other parts fit with the body, with being installed well. 6 Materials
6.1 Stainless steel liner?€?s material shall comply with the provisions of GB 9684 2.1, or it uses the material having the same or better quality.
6.2 The materials of other stainless steel parts shall be consistent with the materials regulated by GB 3280 or GB 4239 or use materials having the same or better quality. 6.3 The materials of seal rings and rubber plastic parts that contact food shall be consistent with the provisions of Table 6, or use materials having the same or better quality.
7 Test??methods
7.1 The insulation performance test of finished products
Conduct the insulation test to the finished products according to 3.1 in GB 5430. It shall use the finished cork.
7.2 Capacity measurement
The MASS of the insulation vessel which is filled with normal temperature water (5-35??C) to spill-over-full AND the sealing cork IS SUBTRACTED by the MASS of the insulation vessel which is without water and with the sealing cork. Then convert the mass into capacity (1 g of water is converted into 1 mL).
7.3 Impact resistance test
7.3.1 Drop test
In the condition of use, fully-fill the non-strap insulation vessel, which has been qualified for insulation effectiveness, with the normal temperature water (5-35??C). Then hang it up (as shown in Figure 5). Drop it from 400 mm height to 300mm-thick hard block board which is fixed horizontally. Inspect it according to the relevant provisions of Table 6. Chapter 4. After all items are qualified, it is deemed as qualified.
