Yunda participated in the formulation of 6 industry standards for the “Plate Chain Paper Roll Vertical Conveyor” industry standard and the “Light Industry Machinery Product Drawings and Design Documents” regulations.

On April 21, 2023, the Ministry of Industry and Information Technology of the People's Republic of China issued the industry standard for the "Plate Chain Paper Roll Vertical Conveyor," as well as the industry standard for "Light Industry Machinery Product Drawings and Design Documents," which covers six major sections including terminology, drawing requirements, format and filling requirements, numbering principles, integrity and modification methods. During this process, Yunda Paper Machinery Co., Ltd. fully leveraged its professional expertise and actively participated in the formulation of these two industry standards.

The 'Plate Chain Paper Roll Vertical Conveyor' standard specifies the model, parameters, and requirements of the plate chain paper roll vertical conveyor, describes the corresponding test methods, and stipulates the contents of inspection rules, markings, packaging, transportation, and storage. It is applicable to the design, production, inspection, and sale of paper roll vertical conveyors used in paper mills and paper product processing plants.

The six industry standards outlined in the "Light Industry Machinery Product Drawings and Design Documents" specify the terminology and definitions related to product and design documents; prescribe the overall requirements for product drawings and requirements for drawing and technical requirement composition; specify the requirements for various document formats and form filling in the industry; establish the basic principles and related requirements for document numbering; stipulate the completeness of document content; establish principles, authorities, procedures for changes to product drawings and design documents, and describe the methods for making changes.

The formulation of these industry standards has unified standards, established relevant requirements and methods and making product drawings and documents more standardized, providing convenience for work.
