The terms and definitions established in GB19434.1--2004 and the following terms and definitions apply to this standard. 3.1
Wooden Intermediate Bulk Containers [BCs
Also known as intrinsic intermediate bulk containers, refer to an intermediate bulk container that meets the definition of intermediate bulk containers in GB19434.1-2004 and consists of a rigid or decomposable wooden body and its lining (but not inner packaging) and corresponding auxiliary equipment and structural devices. Intrinsic intermediate bulk containers are of the following types:
a) 11C natural wood, with lining;
h) 11D plywood: with lining;
c) liF recycled wood, with lining.
4 Requirements
4.1 Wooden IBCs shall not be equipped with top lifting devices. 4.2 The materials used and the manufacturing method shall be compatible with the capacity and purpose of the IBC. 4.3 Natural wood shall be well-seasoned and free of any defects that would reduce the strength of any part of the container. Where quarantine requirements apply, they shall comply with the wood packaging quarantine regulations of the relevant national authorities. 4.4 The body of plywood shall be at least two layers: it shall be made of well-seasoned rotary sawn wood chips, veneers or saw blades: the material shall be dry-dried in batches and free of any defects that would reduce the strength of the container. Adjacent layers shall be bonded with waterproof glue. Other suitable materials may also be used in conjunction with glue to make the body of the container. 4.5 The body of a container made of regenerated wood shall be made of waterproof regenerated wood, such as high-pressure board, particle board or other suitable types. 4,6 The lining shall be made of suitable materials. The strength of the materials used and the manufacture of the lining shall be compatible with the capacity and future purpose of the IBC. The connections and closing devices shall be leakproof and able to withstand the pressure and impact that may occur under normal loading, unloading and transport conditions.
4.7 Any complete chassis that is part of an intermediate bulk container shall be suitable for mechanical loading and unloading operations when the intermediate bulk container is loaded to its maximum total mass.
4.8 The design of the pallet or complete chassis shall avoid any protruding parts to prevent damage during loading and unloading. 4,9 The container body shall be fastened to the chassis to ensure its stability during loading, unloading and transportation: GB 19434.3-2004

Reinforcement devices (such as wooden supports) may be used to increase stacking performance, but such reinforcement devices shall be located outside the inner lining. The stacking load-bearing surface of the intermediate bulk container suitable for stacking shall be able to safely spread the load. 4. 12

5. 1 Test items
No loss of contents, intermediate bulk containers including bottom trays have no permanent deformation that endangers transportation safety. No loss of contents, intermediate containers including bottom trays have no permanent deformation that endangers transportation safety. No loss of contents. If a small amount of contents leaks out of the seal after falling, as long as there is no further leakage, it should also be judged as qualified.

6.1 The manufacturer shall ensure that the wooden intermediate bulk containers produced comply with the provisions of this standard and shall be inspected by the relevant inspection department in accordance with this standard. The user has the right to request acceptance inspection for the received products in accordance with the provisions of this standard. 6.2 Inspection items: Inspect item by item in accordance with the requirements of Section 4 and Chapter 5 of this standard. 6.3 Performance tests should be conducted on wooden intermediate bulk containers when any of the following conditions occur: - Performance tests should be conducted when new products are put into production or when old products are switched to other products. After formal production, if there are major changes in structure, materials, or processes that may affect product performance, if there are slight differences between the intermediate bulk container and its design type, such as slightly smaller external dimensions, etc., selective tests may be conducted on this intermediate bulk container once every six months during normal production; bZxz.net
- After a product has been discontinued for a long time,When production is resumed;----out! When the test result is significantly different from the result of the seventh performance test: the quality supervision agency is requested to conduct a performance test. 6.4 Judgment rules: Test item by item according to the requirements of the standard. If one sample of each item is not qualified, the item is judged to be unqualified. If one item is unqualified, the batch of products is unqualified.
6,5 Unqualified batch processing, the wooden intermediate bulk containers in the unqualified batch are removed and submitted for inspection again, and the basic strictness remains unchanged.
