1.0.1 This specification is hereby prepared with a view to meeting the need of domestic and foreign engineering construction projects and achieving standardization and normalization of engineering design of instrumentation.
1.0.2 This specification is not only applicable to engineering design adopting conventional instrument, but also one adopting DCS. The design document examples attached in this specification are only used for describing the content to be included in the engineering design and the depth to be reached, instead of the recommendation of technical scheme. Each design document has no direct contact and is not displaying a complete engineering design document of instrumentation.
