GB19270.1 General safety regulations for inspection of packaging of dangerous goods for water transport GB19434.1 General safety regulations for inspection of medium-sized containers for dangerous goods 3 Terms and definitions
GB/T4122.1 and GB19434.1 established. The following terms and definitions apply to this standard. 3.1 Intermediate bulk containers (IBCs) are also called intermediate bulk containers. They refer to rigid or flexible transportable containers outside the scope specified in GB 19270.1. These containers: a) have the following capacities:
- not more than 3.0m2 for Class U packaging boxes or Class III packaging bodies and liquids; - not more than 1.5m2 for Class I packaging solids in flexible, rigid plastic, composite, fiberboard and wooden intermediate bulk containers; - not more than 3.0m2 for Class I packaging solids in metal intermediate bulk containers; b) designed for mechanical loading and unloading;
c) able to withstand the stresses generated during loading and unloading and transportation, which are determined by tests. 3.2
Flexible IBCs, also known as flexible intermediate bulk boxes, refer to an intermediate bulk container that meets the definition of intermediate bulk containers in GB19434.1 and is composed of a box body made of film, woven fiber, textile and other flexible materials and their combination, and can be equipped with an inner lining or inner coating as well as auxiliary equipment and loading and unloading devices when necessary. There are several types of flexible intermediate bulk containers: a) 13H1 Woven plastic without coating or lining b) 13H2
Woven plastic with coating
Woven plastic with lining
c) 13H3
Woven plastic with coating and lining
d) 13H4
e) 13H5
f) 13L1
Plastic film
Textile without coating or lining
Textile with coating
GB/T 21592—2008
h) 13L3 Textile with lining
i) 13L4 Textile with coating and lining
j) 13M1 Multi-layer paper
k) 13M2 Waterproof, multi-layer paper
Body
The container itself, including the opening and its closing device, but excluding auxiliary equipment. Applicable to all types of intermediate bulk containers except composite intermediate bulk containers.
Handling device
Various lifting rings, loops, hooks and frames fixed to the intermediate bulk container body or extended from the body material. Applicable to flexible intermediate bulk containers.
Maximum permissible gross mass The mass of the shell and its auxiliary equipment and structural devices plus the maximum permissible loading mass (applicable to all types of intermediate bulk containers except flexible bulk bags).
4 Test equipment
Crane or overhead crane, with a payload of not less than 3t. 5 Test procedurewww.bzxz.net
5.1 Number of specimens
The number of test samples shall be 3 at most.
5.2 Sample preparation
5.2.1 According to the design type and the maximum permissible total mass, the intermediate bulk container used for transporting solids shall be filled to not less than 95% of its capacity, and the intermediate bulk container used for transporting liquids shall be filled to not less than 98% of its capacity. 5.2.2 The pressure relief device shall be determined to be in an inoperative state, or the pressure relief device shall be removed and its opening blocked. 5.2.3 When testing rigid plastic intermediate bulk containers, the test shall be carried out when the temperature of the sample and its contents drops to -18°C or lower. If the material of the test sample has sufficient ductility and tensile strength at -18°C or lower, this temperature treatment condition may not be considered.
5.2.4 The test liquid shall remain in liquid state, and antifreeze may be added if necessary. 5.2.5 The intended cargo of the intermediate bulk container may be replaced by other substances, but it shall not affect the test results. In case of solid material, when another material is used instead, the physical properties (mass, particle size, etc.) of the substitute material shall be the same as those of the material to be transported. It is permitted to use additives such as bags of lead shot, etc., so as to achieve the specified total mass of the package, provided that the additives are placed in such a way that the test results are not affected. 5.2.6 Fiberboard intermediate bulk containers and composite intermediate bulk containers with fiberboard outer packaging shall be conditioned for at least 24 hours under atmospheric conditions of controlled temperature and relative humidity. There are three options from which one can be selected. It is recommended that the atmospheric conditions of 23℃±2℃ and 50%±2% be selected as the best. The other two options are 20℃±2℃ and 65%±2% or 27℃±2℃ and 65%±2%. Note: The daytime measurement process allows short-term fluctuations of ±5% in individual relative measurements, but the average value shall be within the above limits and the fluctuation shall have no effect on the re-testing of the test results.
5.3 Test steps
5.3.1 According to the different packaging categories of the flexible intermediate bulk container, according to the provisions of Table 1, push the sample down from different overturning heights so that any part of its top hits a hard, inelastic, smooth, flat and horizontal surface. Package 1 Overturning height
Packing category I
Note: For the definition of I, II, and blood packaging, see GB 19270.1. Packaging category II
5.3.2 Prepare the intermediate bulk sample to be tested according to the test conditions in 5.2. 5.3.3 The falling method should be such that the most vulnerable part of the bottom of the intermediate bulk container is the impact point. 5.3.4 The same sample is allowed to be subjected to more than two drop tests without affecting the accuracy of the test results. GB/T21592—2008
Unit: meter
Packaging Class II and III
5.3.5 Record whether the contents of the test sample are lost. After the impact, if a small amount of the contents leak out from the seal or seam, as long as there is no further leakage, it shall be considered qualified.
