Some standard content:
GB/T 2934 4—1996 This standard is a revision of GB2934-82 "Intermodal flat pallet external dimensions series" based on ISO6780:1988 "Intermodal general purpose flat pallets - main dimensions and tolerances", and is equivalent to the international standard in terms of technical content. During the revision, those contents of GB2934-82 that have been proven to be suitable for my country's national conditions in practice and do not hinder international use were retained. The various rules specified in this standard involve the external dimensions of intermodal pallets and the dimensions related to the use of pallet trucks, forklifts and other loading and unloading equipment. These regulations are used to ensure the unification of the main dimensions of intermodal general purpose flat pallets of different materials, and regardless of their specific contents, they should meet the same requirements as much as possible. Under the general title of "Intermodal General-purpose Flat Pallet", the following three standards are included: GB/T2934 "Main Dimensions and Tolerances of Intermodal General-purpose Flat Pallet" GB/T4995 "Performance Requirements of Intermodal General-purpose Flat Pallet" GB/T4996 "Test Methods of Intermodal General-purpose Flat Pallet" This standard will replace GB2934-82 from the date of entry into force. Appendix A of this standard is a reminder appendix. This standard is proposed by the Ministry of Communications of the People's Republic of China. This standard is under the jurisdiction of the Standards and Metrology Institute of the Ministry of Communications. The drafting unit of this standard: Standards and Metrology Institute of the Ministry of Communications. Dalian Port Authority and Shanghai Port Design and Research Institute participated in the drafting. The main drafters of this standard: Xiong Caiqi, Gao Qizhai, Bao Yaoyou. This standard is revised for the first time. This standard is entrusted to the Standards and Metrology Institute of the Ministry of Communications for interpretation. 3 GB/T2934--1996 ISO Foreword ISO (International Organization for Standardization) is a global federation of national standards bodies. The work of drafting international standards is usually carried out by ISO technical committees. Each member group has the right to send representatives to participate in the technical committees of the topics it is concerned with. International organizations, whether governmental or non-governmental, can also participate in the work as long as they have liaison relations with ISO. ISO and IEC (International Electrotechnical Commission) work closely together in the promotion of all electrotechnical technical standards. The draft international standard adopted by the technical committee must be approved by the member groups before it is determined as a formal international standard by the ISO Council. According to ISO regulations, any draft international standard must be approved by 75% of its members before it can be formally accepted as an international standard. International Standard ISO6780 was drafted by ISO/TC51\Pallets for Handling Piece Goods” Technical Committee. Appendix A of this international standard is for reference only. 1 Scope National Standard of the People's Republic of China General-purpose flat pallets for through transit of goods--Principal dimensions and tolerances GB/T 2934-1996 eqv IS0 6780:1988 Replaces GB2934-82 This standard specifies the external dimensions of single-layer and double-layer single-sided intermodal general-purpose flat pallets made of wood, plastic or steel, as well as the relevant dimensions for transport trucks, forklifts and other loading and unloading equipment.

When this standard is published, the versions shown are valid. All standards will be revised, and parties using this standard should explore the possibility of using the latest versions of the following standards. GB3716-83 Pallet Terminology 3 Definitions This standard adopts the following definitions. All definitions listed in GB3716 apply to this standard. 4 Dimensions 4.1 Plane dimensions 4.1.1 Nominal outer dimensions The nominal outer dimensions of the pallet plane are: 1200mm×1000mm, 1200mm×800mm, 1140mm×1140mm, 1219mmX1016mm mm. 4.1.2 Tolerance of nominal outer dimensions The tolerance of the nominal outer dimensions of the plane is 0~-6mml. 4.2 Vertical dimensions of fork holes 4.2.1 Except for free fork hole pallets with a fork hole height of not less than 95mm, the fork hole height of the pallet should not be less than 98mm. See Appendix A (Suggestive Appendix) Figure A1. 4.2.2 The distance from the top surface of the pallet groove to the ground should not be less than 55mm; the distance to the bottom of its own longitudinal beam should not exceed 45mm. See Appendix A Figure A2. 1) In order to meet the specified tolerances, some materials need to be manufactured due to shrinkage. A positive tolerance. The manufacturing tolerance of this pallet is ±3mm. Approved by the State Administration of Technical Supervision on December 4, 1996 and implemented on August 1, 1997 GB/T2934--1996 4.2.3 For some four-way access pallets and double-sided pallets with free fork holes, the distance from the lower edge of the lowest part of the top deck to the ground should not exceed 127mm; for pallets with bases on all sides, this dimension should not exceed 156mm, see Appendix A Figure A3. Note: The dimensions specified in 4.2.1.4.2.2 and 4.2.3 are applicable to pallets made of hygroscopic materials with an average moisture content of (20±2)%. 4.3 Horizontal dimensions of fork holes and openings 4.3.1 The horizontal dimensions of fork holes and openings for two-way and four-way access pallets are shown in Figure 1 and Table 1; the horizontal dimensions of fork holes and openings for some four-way access pallets are shown in Figure 2 and Table 2. 4.4 Dimensions of bottom decking components To facilitate the insertion of the fork wheels of the pallet transporter, the thickness of the bottom decking components of the pallet should not exceed 28mm. If the thickness exceeds 10mm, chamfers should be added to the front and back of each side of the top surface of the bottom decking components according to the following requirements; a) The angle between the chamfered slope and the horizontal plane should be 40°±5°; b) The vertical height of the chamfer should not exceed: 15mm (wood) -10mm (other materials) 4.5 Wing width of pallets with wings The width of the wing should not be less than 65mm. 4.6 Support surface of the bottom deck The support surface of the bottom deck of the pallet should not be less than 35% of the plane size of the pallet. 4.7 Squareness of the pallet During manufacturing, the difference in the length of the two diagonals of the pallet plane should not exceed 13mm. 6 Nominal dimensions of pallets (l or w) GB/T2934—1996 a) Fork hole b) Opening Figure 1 Horizontal dimensions of fork holes and openings for two-way and four-way fork access pallets Horizontal dimensions of fork holes and openings for two-way and four-way fork access pallets Table 1 Fork hole and opening Nominal dimensions of pallets 1 000×1 200 1 200×1 000 800×1 20032 1 200×800 1 219×1 016 1 016×1 219 1140×1140 GB/T2934-1996www.bzxz.net Figure 2 Horizontal dimensions of fork holes and openings for partial four-way access pallets Table 2 Horizontal dimensions of fork holes and openings for partial four-way access pallets (see Figure 2) Fork holes and openings 1) When 11 and 12 are at their maximum values, the adaptability of the pallet strength is optimal. 2) These values do not allow the pallet to be loaded and unloaded using a pallet truck with front and rear tugs. Therefore, 12 should be maximized as much as possible so that the pallet can be loaded and unloaded by a pallet truck. 3) Partial four-way access pallets with a length of 800mm should not be loaded and unloaded using a pallet truck with front and rear tugs, even when 12 is at its maximum value.
