1 Scope This Part in DL/T 5210 specifies the relevant requirements in the construction quality acceptance standard for instrumentation and control device ("instrumentation and control", or "I&C"), and quality evaluation for individual project, individual unit and overall project. This Part is applicable to the construction quality acceptance and engineering quality evaluation of I&C device for newly-built, extended and rebuilt thermal power generation projects with unit capacity 300MW~1000MW. The unit capacity construction quality acceptance and evaluation of I&C device for thermal power generation project with unit capacity under 300MW may comply with this Part by reference. 2 Normative References The following normative documents contain provision which, through reference in this text, constitute provisions of this Part.

in case of any nonconformity, it shall comply with the requirements in Article 4.1.12 in this Part. 3.0.3 The engineering quality evaluation shall be conducted for the projects that apply the "high quality" titles. 3.0.4 The engineering quality evaluation shall be conducted by the three phases (stage) - individual project, individual unit and overall project. 3.0.5 The construction quality evaluation for individual project shall be conducted upon that the construction quality acceptance for all subsystems is qualified and the collection and rearrangement of engineering technical document is completed, and the evaluation shall cover the whole work content before 168-h trial running with full load. 3.0.6 The quality evaluation for individual unit shall be conducted after the construction quality acceptance for all individual projects and the 168-h trial running of the unit with full load are completed and the environmental works supported are normally put into operation. The synergic system shall be bought into the evaluation for the first unit. 3.0.7 The quality evaluation for overall project shall be conducted after the quality evaluation for all individual units, the performance tests of the units and the engineering archives evaluation are completed.
