1.0.1 This code is formulated to implement relevant national principles and policies, standardize construction requirements, unify inspection method and define acceptance standard so as to ensure construction and installation quality and to achieve energy saving, material and water conservation, environmental protection and safety operation during the construction and acceptance of cleanrooms and associated controlled environment (referred to as cleanroom from Chapter 3).
1.0.2 This code is applicable to the construction and acceptance of newly-built and reconstructed, entire and assembling as well as fixed and moving cleanrooms and associated controlled environment.
1.0.3 The construction and acceptance of cleanrooms and associated controlled environment shall meet the following requirements:
1 It shall be carried out by professional qualified construction enterprise approved by competent development department according to approved documents and drawings. The constructors shall receive training and assessment on construction and acceptance specification of cleanroom; the special category of workers shall have work license and shall be supervised all over the process by supervision organization with professional supervision aptitude and specialized training.
2 Construction organization design shall be formulated before construction. During construction, different categories of workers shall be keep close coordination and carry out construction according to the specified procedure. No construction shall be carried out for engineering projects without drawings, technical requirements and construction organization design. The change file from design unit shall be provided during engineering construction to modify the design. No performance acceptance shall be carried out on engineering projects without completion drawing.
3 The specification, model, performance and technical index of all materials, equipments, finished products and semi-finished products used in projects shall meet the requirements of design and current relevant national standards, and there shall be complete legal quality evidentiary documents. Inspection must be carried out if there is any doubt on their quality. The overdue materials shall not be used any more.
4 After finishing complex procedure construction of section subitem project and engineering, it shall carry out section acceptance. If the section acceptance is unqualified, it must be reworked until qualified and shall be recorded and filed.
1.0.4 This code shall be used together with the current national standard "Unified Standard for Constructional Quality Acceptance of Building Engineering" (GB 50300).
The construction and acceptance of cleanrooms and associated controlled environment shall not only comply with the requirements stipulated in this code, but also shall meet those in the relevant current ones of the nation.
