BB/T 0020-2001
Combined uneven pallets are made of plastic and plant fiber as the main raw materials. First, they are made into profiles, and then various components are formed by the profiles. Finally, they are combined and processed with fasteners such as screws. The pallet has the characteristics of being strong, reliable, reusable, and recyclable. The combined plastic-wood flat pallet is a new product made of new materials and new processes. It not only has the advantages of wooden pallets, but also combines the characteristics of plastic pallets. It is a new product with potential and prospects. At present, there is no national or industry standard for this type of product. Based on the relevant provisions of the Standardization Law, this product standard is formulated. The formulation and implementation of this standard will promote the standardized development of this product and promote the improvement and promotion of product quality in this industry. 1
１ Scope
Combined plastic wood flat pallet
BB/T0020—2001
This standard specifies the product classification, technical requirements, test methods, inspection rules and markings, transportation and storage of combined plastic wood flat pallets. This standard defines the terms of combined plastic wood flat pallet components. This standard is applicable to plastic wood flat pallets (hereinafter referred to as plastic wood flat pallets) that are made of polyolefin plastics (FP, IIDPE, LDPE, etc.) and plant red fibers (sawdust, husk powder, etc.) as the main raw materials. After the materials are formed, they are assembled with screws and other fasteners, and can be used in two or four directions. They are single-sided or double-sided.
