1 General provisions
1.0.1 This code is formulated to guide and standardize the design of generic cabling system of civil transport airport terminal building and promote the construction of generic cabling system of civil transport airport terminal building.
1.0.2 This code is applicable to the design of generic cabling system and system upgrading of new terminal building of civil transport airport (including civil part of military & civil airport). The upgrading of the original system may be implemented with reference to this code.
[Explanation of Provisions] The newly-built generic cabling system of the terminal building refers to the newly-built system in airport construction, reconstruction, extension and relocation projects.
1.0.3 The design of the generic cabling system of the terminal building shall aim at the specific characteristics of civil transport airports, and be "safe and applicable, advanced in technology, economical and reasonable, environment protecting, and easy to expand".
1.0.4 In addition to this code, the design of generic cabling system of the terminal building shall meet the relevant current national provisions or standards.
