- Scope
- 1.0.1 In order to meet the needs of domestic and foreign engineering construction projects and standardize and normalize the professional engineering design documents for automatic control, these regulations are specially prepared. 1.0.2 This provision applies not only to engineering design using conventional instruments, but also to engineering design using DCS. The examples of design documents attached to this regulation are only used to illustrate the content and depth that the engineering design should include, and are not intended to be a recommendation for technical solutions. There is no direct connection between the various design documents, nor does it present a complete automatic control professional engineering design document.
