Code for Engineering Acceptance of
Generic Cabling System
1. General Provisions
1.0.1 This Code is formulated with a view to uniform the technical
requirements on installation quality inspection, routine inspection and
final acceptance of the generic cabling system for buildings and
building complexes.
1.0.2 This Code is applicable to the acceptance inspections of the generic
cabling systems in the construction, extension and renovation of
buildings and building complexes.
1.0.3 In the implementation of the generic cabling system, the requirements
on the engineering acceptance stated in the engineering documents
and contract documents shall not be lower than the provisions of this
Code.
1.0.4 In the construction procedure, the construction organization must
comply with the relevant provisions of this Code on engineering
acceptance. The drafting organization shall, through on-site
representative or supervisors, strengthen the construction quality
inspection and timely organize inspection and acceptance for the
concealed works.
1.0.5 The generic cabling system shall comply with the design requirements.
Self-check testing and final acceptance testing shall be carried out
prior to the engineering acceptance.
1.0.6 For the engineering acceptance of generic cabling system, not only the
requirements stipulated in this Code, but also those in the current
relevant ones of the nation shall be complied with.
2. Environment inspection
