The purpose of this part of GB/T5021 is to establish a classification table for items that can be used in a technical field. The symbols used in the original standard GB/15D94-185, which was used as Appendix E in GB/T5094.1, are still retained unless they conflict with the general method. Fourth, we should try to find a solution that is as stable as possible. Appendix A of this specification provides the basic requirements for the code to indicate the type of items. Appendix A explains that "items are classified according to their use or functions related to a certain process, except that "items are classified according to their location in the infrastructure." Appendix B gives an extract from the table in 15014617-6. 1 Scope
GB/T 5094.2—2003/1EC 61346-2r2000 Industrial systems, devices and equipment and industrial products - Structural principles and reference codes
Part 2, Classification and classification codes of items Www.bzxZ.net
This part of GB/T 5094 specifies the classification of items and the letter codes used to indicate the item categories in the license codes. The classification table is applicable to items in the field of technology and can be used to define any position in the structure of the items according to the limit "I/T4.2. The points are not marked in the quarterly report to study the potential of the items. 2 Normative references
