![]() ![]() There is also a square pallet among the six international standard specifications, namely the 1067mm×1067mm (42in×42in) type commonly used in Australia. With the long-term unremitting efforts of the Japan-South Korea Pallet Standardization Organization, in 2013, T11 finally became another international standard specification. However, the 1140mm specification has not been able to change the international standardization process of T11. It was first listed in ISO3676 "Packaging Unit Cargo Dimensions" in 1982, and then listed in ISO6780 in 1988 in the international standard of "Main Dimensions and Tolerances of Universal Flat Pallets for Intermodal Transport". In order to make full use of the bottom flat area of the container and promote the unification of the Tmm series, the pallet circles of the two parties finally agreed to increase the 1100mm to 1140mm. The establishment of the 1140mm×1140mm specification can be said to be an intermediate product of a long-term dispute between European countries represented by the 1200mm series and Japan -South Korea which vigorously promote the 1100 mm×1100 mm pallet (referred to as T11). It is generally believed that this specification best matches the size of the container. In the same year, another square 1140mm×1140mm pallet was added to ISO6780. This series of pallets can only be stacked in a criss-cross pattern in the container, and cannot be effectively used in the limited space. It does not match the international standard (approximately 2330 mm) for the internal width of the shipping container. However, the 1200mm series has its disadvantages that cannot be remedied. It can be said that48in×40inis the British version of the 1200mm series. In fact, there is not much difference from 1200× 1000mm, and the difference of length and width is less than 2cm between48in×40in and 1200×1000mm. In response to their strong request, ISO added the standard 48in×40in in imperial units to the 1200mm series of international standards in 1988. However, some western countries such as the United States often use imperial units. This standard is soon accepted by various European countries, it has become the basic specification for the manufacture and use of pallets in Europe. ![]() It is generally believed that it was formulated based on the European unified packaging standard size of 600mm×400mm. This series originated in the European continent. The original international standard specifications were only the 1200 series (ie 1200×1000mm and 1200×800mm). It is almost impossible to do this in the short term. Therefore, although it is the common aspiration of the international logistics community to unify the intermodal flat pallet specifications and minimize logistics costs, to achieve this requirement, it is necessary to resolve the balance of interests of various regions or national groups on the pallet issue. It is a contradictory reflection of the interests of different regions and different national groups on the issue of pallet standards. The root cause is that each specification in ISO6780 has different origins. The coexistence of the six global pallet standard specifications is not an ideal result. So there are currently six international standards for pallets. After several stages of deliberations by the ISO/TC51 Pallet Standardization Technical Committee, the International Organization for Standardization has revised the ISO6780 "Main Dimensions and Tolerances of Intermodal Flat Pallets" in 2003.On the basis of the origina four specifications of 1200×1000mm, 1200×800mm, 1219×1016mm (ie 48in×40in) and 1140×1140mm, two specifications of 1100×1100mm and 1067×1067mm have been newly added. ![]()
