The specifications of these two standards are combined in combination with the situation in my country, and the specifications of 2L and 3L are added, and the specifications below 1L are removed. In the test method, the stacking test is added compared with JISZ1602-1989 18-liter metal square barrel". According to the requirements for use as Class II dangerous goods packaging, the airtightness test value is set at 20 kPa, and the pressure resistance test is deleted. This standard is proposed by China Packaging Corporation. This standard is under the jurisdiction of the Metal Container Sub-Technical Committee of the National Packaging Standardization Technical Committee. The responsible drafting units of this standard are: Standardization Research Institute of the Ministry of Chemical Industry, Tianjin Paint Packaging Equipment Factory.

GB/T17343-1998
When the production of square barrels has one of the following situations, type inspection should be carried out: a) Trial design identification of new products or old products; b) After formal production, if there are major changes in structure, materials, and processes that may affect product performance; c) During normal production, once a quarter;
d) When the product is resumed after a long period of suspension; e) When the factory inspection results are significantly different from the last type inspection results; f) The national quality supervision agency proposes to conduct type inspection. 7.3 Square barrels should be inspected batch by batch. The manufacturer considers the daily output as a batch, and the user considers the delivery quantity as a batch. The inspection batch should consist of products of the same category, volume and production conditions. The normal inspection one-time sampling plan of GB/T2828 is adopted. 7.4 The basic requirements specified in 5.1 of this standard are specified as the inspection level of special inspection level S-2, the qualified quality level is 6.5, and the number of samples drawn and the number of qualified judgments are shown in Table 5.
