This standard specifies the test methods for large transport packages to be tested for drop, stacking, lifting, etc. This standard is mainly applicable to transport packages with box-shaped structures, and can also be used as a reference for packages of other shapes with equivalent mass and volume.
Some standard content:
GB/T5398—1999 This standard adopts the American Society for Testing and Materials standard ASTMD1083--1991 "Test methods for unit loads and large transport packages for mechanical storage and transportation" in a non-equivalent manner. It revises GB/T5398--1985 "Test methods for large transport packages". When revising ASTMD1083-1991 in a non-equivalent manner, the concept of large transport packages was redefined, and the railway transportation test methods and other regulations in GB/T5398-1985 were cancelled; but for the test methods for unit loads on pallets, since my country already has similar standards, this standard does not include this aspect. When testing large transport packages, appropriate test items should be selected from the multiple test methods specified in this standard according to the actual specific conditions. This standard will replace GB/T5398-1985 from the date of implementation. This standard is proposed by China Packaging Corporation. This standard is under the jurisdiction of the National Technical Committee for the Promotion of Packaging Standards. The main drafting units of this standard are: Mechanical Science Research Institute of the Ministry of Machinery Industry, China Export Commodity Packaging Research Institute, Standard Metrology Research Institute of the Ministry of Railways, and Standard Metrology Research Institute of the Ministry of Transport. The main drafters of this standard are: Huang Xue, Zhang Xiaojian, Li Jianhua, Zhang Jin, Xiong Caiqi, and Yi Xiguang. 344 1 Scope National Standard of the People's Republic of China Test methods for large transport packages Test methods for large transport packages This standard specifies the test methods for falling, stacking, lifting, etc. of large transport packages. GB/T 5398—1999 Replaces GB/T 5398-1985 This standard is mainly applicable to transport packages of box-shaped structure, and can also be used as a reference for packages of other shapes with equivalent mass and volume. 2 Referenced standards The provisions contained in the following standards constitute the provisions of this standard through reference in this standard. When this standard was published, the versions shown were all valid. All standards are subject to revision. Parties using this standard should explore the possibility of using the latest versions of the following standards.

Transport packaging Method of marking various parts during the test Transport packaging Transport packaging Transport packaging Temperature and humidity conditioning treatment Stacking test method Rolling test method Spraying test method Transport packaging Transport packaging Transport packaging Large transport packaging largetranspartpackageTransport packaging whose mass and volume require mechanical loading and unloading. 4 Test principle Tipping test method General principle for compiling performance test outline Quantitative data for compiling performance test outline The various tests included in this standard use environmental simulation methods to reproduce the hazards caused by falling, stacking, lifting, etc. of packaging during circulation. 5 Test equipment 5.1 Lifting equipment Any suitable equipment such as crane, forklift, pulley block or special test equipment can be used. 5.2 Impact table The impact table shall comply with the requirements of Chapter 4 of GB/T4857.6-1992. Approved by the State Administration of Quality and Technical Supervision on September 7, 1999 and implemented on February 1, 2000 6 Test procedure 6.1 Preparation of test samples GB/T5398--1999 Prepare test samples in accordance with the requirements of GB/T4857.17. 6.2 Numbering of various parts of the test sample Number various parts of the test sample in accordance with the provisions of GB/T4857.1. 6.3 Pretreatment of test samples If necessary, select appropriate conditions for temperature and humidity pretreatment of test samples according to the provisions of GB/T4857.2. 6.4 Temperature and humidity conditions during the test If the test sample is pretreated, the test should be carried out under the same temperature and humidity conditions as the pretreatment. If the pretreatment conditions cannot be met, the test must be started within 5 minutes after the test sample leaves the pretreatment conditions. 6.5 Selection of test strength value Determine the test strength value according to the provisions of GB/T4857.18 and this standard. 6.6 Test 6.6.1 Drop test This test includes surface drop test, edge drop test and corner drop test. 6.6.1.1 Surface drop test Place the test sample on the impact table specified in 5.2 in the predetermined state, lift one end to the predetermined drop height, and let it fall freely to produce impact (see Figure 1). Supporting member Height of drop Figure 1 Schematic diagram of surface drop test 6.6.1.2 Edge drop test Place the test sample on the impact table specified in 5.2 in the predetermined state, lift one end to the cushion or other support, and then lift the other end to the predetermined height, and let it fall freely. The cushion or other support is at right angles to the length direction of the test sample. The height of the cushion should ensure that there is no support between the two end faces of the test sample when it falls, and when the other end is lifted to prepare for falling, the sample should not slide at the cushion (see Figure 2). Supporting member Drop height Figure 2: Schematic diagram of edge drop test Apple pad 6.6.1.3 Corner drop test After raising one end of the test sample according to the method in 6.6.1.2, place a 100mm~250mm pad under one corner of the raised end, then lift the bottom corner opposite to the corner to the predetermined drop height and let it fall freely to produce an impact (see Figure 3 ), 346 6.6.2 Stacking test Supporting member Drop height GB/T5398-1999 Figure 3 Schematic diagram of corner drop test Inclined pad Flat pad In order to assess the top bearing capacity of the transport package, a top bearing test should be carried out; in order to assess the upper stacking load capacity of the side of the transport package, a side bearing test should be carried out. 6.6.2.1 Top bearing test Place a weight with a bottom size of 250mm×250mm on the top of the test sample. Apply a predetermined uniformly distributed load. The load error should not be greater than 2% of the predetermined value. The weight should be placed within the side and end edges of the top surface. Place one for every 0.1m area, as shown in Figure 4. Figure 4 Schematic diagram of top surface load test 6.6.2.2 Side load test The side load test is carried out in accordance with the provisions of GB/T4857.3. 6.6.3 Lifting test Place the wire rope at the predetermined lifting position on the bottom surface of the test sample. The angle between the wire rope and the top surface of the test sample is 45°~50°. After the test sample is lifted to a certain height (about 1.0m1.5m) by the lifting device at normal speed (see Table 1), it is repeatedly raised, lowered and moved left and right for 5 minutes in an emergency lifting and braking manner, and then dropped to the ground at normal speed. Repeat the above test 3 to 5 times (see Figure 3).
