GB/T 16563—1996
This standard is formulated in accordance with ISO1496-3:1995 "Series 1 Container Technical Conditions and Test Methods Part 3: Liquid, Gas and Pressurized Dry Bulk Tank Containers" of the International Organization for Standardization, and is equivalent to it in terms of technical content and writing rules. It is imperative to adopt international standards or advanced foreign standards, especially for container standards, it is even more important to adopt international standards. Only in this way can we adapt to the needs of international trade, technology and economic exchanges as soon as possible, so as to facilitate international integration. For this reason, the formulation of this standard is equivalent to the international standard ISO1496-31995 in terms of technical content and writing rules. The difference is that this standard converts the format of the international standard into the format of the national standard in accordance with GB/T1.1-1993 "Guidelines for Standardization Work Unit 1: Rules for Drafting and Presentation of Standards Part 1: Basic Provisions for Standard Writing". In addition, ISO1496-3:1995 is a component of the five parts of the ISO1496 series standard, while this standard is an independent standard.
This standard specifies the dimensions, rated mass, design requirements and test methods of liquid, gas and pressurized dry bulk tank containers, and has important guiding significance for the design and production of tank containers. Appendix A, Appendix B and Appendix C of this standard are all standard appendices; Appendix D of this standard is a prompt appendix.

ISOForeword
The International Organization for Standardization (ISO) is a worldwide federation of national standardization organizations (ISO member groups) in various countries. The drafting of international standards is generally carried out through the technical committees of ISO. Each member group has the right to send representatives to participate in the technical committees of the topics they are concerned about. All governmental and non-governmental international organizations that have liaison relations with ISO also participate in the relevant work. The draft international standards prepared by each technical committee are distributed to the member groups for comments before being adopted as international standards by the ISO Council. According to ISO's procedures, the approval votes in the member group vote exceed 75% to be considered passed. The international standard ISO1496-3 was drafted by the second technical committee of the ISO/TC104 container technical committee - the special container technical committee.
The fourth edition of ISO1496-3 abolishes and replaces the revised technical parts in the third edition [ISO1496-3:1991 standard]. The load transfer area test for 1AAA and 1BBB tank containers has been added (see 6.10 and Figure A19), and the tests and requirements for grab lifting areas and accompanying objects have been deleted.

The external dimensions and tolerances of the containers listed in this standard have been specified in ISO668. However, the height of the tank containers with the code 1AX, 1BX, 1CX and 1DX can be reduced. Any part and various accessories of the tank container shall not exceed the external dimensions. 4.2 Rated value
The rated value "R" is the total mass of the container, which has been specified in ISO668. However, the R rating of 1BBB, 1BB, 1B, 1CC and 1C tank containers can be designed, tested and operated according to certain high-density cargoes, which can be higher than the specified value of ISO668. For all containers, the R value shall not exceed the rated value of 1AAA, 1AA and 1A containers in any case. 5 Design requirements
5.1 General
The frame, tank body and optional facilities of various types of tank containers shall comply with the following provisions: 5.1.1 The ability of tank containers to withstand the design load shall be confirmed by calculation and test. 5.1.2 The strength requirements of tank containers are detailed in the diagrams listed in Appendix A (Annex to the standard) (unless otherwise specified, these requirements apply to all tank containers as a whole).
5.1.3 The strength requirements of corner fittings (see 5.2) are specified in ISO1161. 5.1.4 The container shall be able to withstand the various loads and loadings listed in Chapter 6 of this standard. 5.1.5 When designing a tank container, the inertia force that occurs during transportation conditions should be considered. The designed longitudinal force is 2Rg, the lateral force is Rg, and the vertical force is 2Rg2. They are evenly applied to the centroid of the tank body. The vertical load is the total value including the dynamic load effect. The above loads will not cause an increase in the pressure of the steam space in the tank. When designing, the equivalent pressure can be considered. 5.1.6 Each tank container must be able to withstand the inertia forces listed in Article 5.1.5, as well as the static pressure head when the internal load reaches the R value. At this time, the tank body and any compartment are filled with the densest liquid cargo or dry bulk cargo. 5.1.7 The load effect under any dynamic operating conditions during the test only needs to reach the specified value and does not need to exceed the corresponding test value. That is, the various test requirements listed in Appendix A (Standard Appendix) and Chapter 6 should not exceed the corresponding regulations under any working conditions. 5.1.8 The opening and closing devices on the tank containers, which are dangerous due to not being fastened securely, should be equipped with corresponding locking devices, and the positioning marks indicating locking should be set on the surface of the operating position. 5.1.9 The tank containers are not equipped with fork grooves.
Note 3: When a fully loaded or partially loaded tank container is transported by forklift, accidents may occur due to stability problems, and there is also a danger that the forklift's fork will break the body.
5.1.10 The material of the tank container should not be affected by the type of goods transported and the operating environment. It is necessary to fully consider the problems such as the large changes in external temperature, the corrosiveness of the atmosphere, and the uncontrolled emission in the event of a fire. 5.1.111 The design of AAA and 1BBB tank containers should take into account the instability of these containers under dynamic conditions, and their design requirements should be consistent with the requirements of 1AA and 1BB tank containers when they are partially full during road/rail transportation. 5.2 Corner fittings

6 Tests
6.1 General
Unless otherwise specified, all the tests listed in 6.2 to 6.11 shall be carried out according to the conditions of their design and use. Each container shall be subjected to a pressure test (test 12), which shall be carried out after the completion of other tests.
In addition, containers carrying dangerous goods shall also comply with the relevant test requirements specified by the competent authorities. Note 5: Regarding the dynamic load test, since an ideal method has not yet been obtained, it is not included for the time being. 6.1.1 The symbol "P" indicates the maximum loading capacity of the container under test, and the formula is: P=RT
Where: R—rated value;
T-—the mass of the container itself.
The symbol W\ indicates the loading capacity when the tank is filled with water. Note 6: The listed R, P, T and W are all mass concepts. If the test requirement is based on gravity values, the expression of "force" should be: Rg, Pg, Tg, Wg
The above values are in Newton or dry Newton. The term "load" (laad) is used to express a unit quantity and is a mass concept. The term "loading" (loading) is used for loading and is a force concept. 6.1.2 Unless otherwise specified, tank containers should be tested with the corresponding liquid or solid bulk cargoes to achieve the specified test load and loading requirements.
If the test load or loading requirements cannot be achieved by the above method, or the method itself is not ideal, it may be considered to fill the tank with the corresponding liquid or solid cargo and then supplement the load or loading. All loads or loadings applied are simulated as uniform loads. According to the calculated bending moment curve, a 20% error can be considered. Note 7: As long as the specified test load can be achieved, other loading or loading methods are also feasible (for example: methods used for internal longitudinal and transverse bolting tests).
6.1.3 The test loads and loadings specified in the following tests are minimum requirements. Note 8: Special care should be taken during loading operations for containers with codes 87 and 88. 6.1.4 The dimensions required in each test clause shall be in accordance with the following standards: a) the relevant dimensions and design requirements in Chapters 4 and 5 of this standard; b) ISO668;

The force shall be applied through the corner fittings specified in ISO1161 or through dummy parts with the same geometry (i.e. the external dimensions, chamfers of openings and radii of peripheral corners are the same). If dummy parts are used, their design must ensure that the forces borne by the container during the test are the same as when corner fittings are used.
For various loading methods, the angular displacements produced by the plane of force application and the force-bearing surface of the box shall be reduced to a minimum.

This test should also be used to verify the ability of the container to withstand the various forces generated by the tank load under acceleration during the lifting operation.
6.3.2 Method
The load of the tank container to be tested should be evenly distributed, the sum of the mass of the container and the test load equal to 2R (see 6.1.2), and then it should be lifted smoothly from the four corner fittings simultaneously, avoiding obvious acceleration or deceleration. The lifting force for tank containers other than 1D and 1DX should be vertical. Each sling used to lift a 1D or 1DX container should be at an angle of 60° to the horizontal plane. 6) 25.4 mm = 1 in; 38 mm = 1 in. 348

After the test, the tank container shall not leak or have permanent deformation or abnormality that affects normal operation, and its size can still meet the requirements of loading, unloading, securing and transshipment.
6.6 Test 5 Internal longitudinal bolting test
6.6.1 General
This test is carried out separately to verify the ability of the tank body and frame of the tank container to withstand the longitudinal inertia force caused by the internal cargo. The longitudinal inertia force is shown in 5.1.
9 The force generated by vertical acceleration has been included in Test 2 and Test 3. 10 For containers without longitudinal connecting rods, only Test 4 can be carried out. 6.6.2 Method
7) 38 mm-1/ in.
GB/T 16563—1996
Make the sum of the self-mass of the tank container under test and the test load equal to R. Make the longitudinal axis of the tank container vertical (the allowable error is 3°). Place it in this state for 5mina) The tank container is supported by its lower end structure, and only the two bottom corner fittings at the lower end are bolted vertically and horizontally, and the two bottom corner fittings at the upper end are also bolted horizontally.
b) The container is supported by the four corner fittings at its lower end. Method b) can only be used for testing when the tank body is completely supported by the bottom structure of the container or the competent authority believes that the reliability of the connection between the tank body and the frame has been fully demonstrated through tests 4 and 8. When the partition structure in the tank container or the connection between the body and the frame is asymmetrical about its vertical axis, the two ends should be tested separately.
6.6.3 Requirements
After the test, the tank container should not leak and have permanent deformation and abnormality that affect normal use, and the size should still meet the requirements of loading and unloading, securing and reloading operations.
6.7 Test 6 - Internal transverse bolting test 6.7.1 General
This test is carried out separately to verify the ability of the tank container's body and frame to withstand the transverse inertia forces caused by the internal cargo. The transverse inertia forces are given in 5.1.
11 The forces caused by vertical acceleration are included in Tests 2 and 3. 12 Containers without longitudinal connectors may be subjected to Test 4 only. 6.7.2 Method
Make the sum of the mass of the tank container and the test load equal to the R value. Make the transverse axis of the tank container in the vertical direction (allowable deviation 3°). Leave it in this state for 5 minutes.
a) Bolt the two bottom corner fittings on the lower side of the lying tank container vertically and horizontally, and only bolt the two bottom corner fittings on the upper side in the horizontal direction.
b) Use only the four bottom corner fittings for support. Only when the tank is completely supported by the bottom structure of the container or the competent authority believes that the reliability of the connection between the tank and the frame has been fully demonstrated through test 4 and test 8, can the test method b) be used for testing. 6.7.3 requires that after the test, the container should not leak or have permanent deformation or abnormality that affects normal use, and the size should still meet the requirements of loading, unloading, securing and transshipment operations.
6.8 Test 7 - Transverse rigidity test
6.8.1 General
This test is to verify the ability of various types of tank containers, except 1D and 1DX, to withstand the transverse push and pull generated by the ship during navigation.
6.8.2 Method
The tank container is in the empty (T) state, with its four bottom corner fittings placed on four supports at the same level, and the bottom holes of the four bottom corner fittings are bolted in the transverse and vertical directions through the fixing device. The transverse bolting is only provided on the bottom corner fittings at the same diagonal end of the force-applying top corner fitting.
If each end is tested separately, the vertical bolting is only provided at one end of the test. A force of 150kN is applied to each top corner fitting separately or simultaneously on one side of the tank container, with the line of force applied parallel to the bottom structure and end structure of the tank body, first toward the top corner fitting, and then in the opposite direction. 8) 150kN33700lbf.
