Introduction of SY 4200-2007

1 Scope This code specifies the general standard for the quality acceptance of various project construction in oil and gas construction engineering, as well as the content, acceptance condition, organization and procedures for the quality acceptance of inspection lot, subitem project, subsection (sub-subsection) Engineering and unit (subunit) project construction. This code is applicable to the handing over and quality acceptance of oil and gas construction engineering. 2 Normative References The following documents contain provisions which, through reference in this text, constitute provisions of this code. For dated reference, subsequent amendments to, or revisions of, any of these publications do not apply. However, all parties coming to an agreement according to this code are encouraged to study whether the latest editions of these documents are applicable. For undated references, the latest edition of the normative document is applicable to this code. GB 50300 Unified Standard for Constructional Quality Acceptance of Building Engineering 3 Terms and Definitions The following terms and definitions are applicable to this code. 3.1 Oil and gas construction engineering It refers to the engineering efforts such as planning, survey, engineering and construction, completion and the completed engineering entity carried out for building, rebuilding or expanding oil-gas field construction, oil & gas storage and transportation, as well as its supporting facilities. 3.2 Quality of oil and gas construction engineering It refers to the total ability of oil and gas construction engineering meeting the express and implied characteristics in structure, safety, use function, durability and environment protection as well as relevant standard provisions or contract agreement. 3.3 Acceptance On the basis of the quality of oil and gas construction engineering passing the self-inspection and evaluation of construction organization, all organizations participating in the development activities jointly carry out sampling reinspection for the quality of inspection lot, subitem project, subsection (sub-subsection) project and unit (subunit) project and make written confirmation for the construction quality according to relevant standards. 3.4 Site acceptance It refers to the inspection carried out for the on-site material, components, and equipment according to relevant standard provisions to make a confirmation on the quantity conformity condition. 3.5 Inspection lot It refers to an inspection body composed of a certain quantity of samples collected for inspection according to the same production conditions or the specified mode. 3.6 Inspection It refers to activity of conducting measurement, inspection and tests for the properties of testing items, comparing the results and the requirements, and determining the conformity of each property. 3.7 Evidential testing It refers to the inspection that the persons concerned of the construction organization do sampling on site under the supervision of the supervision organization or the development organization, and send the sample to the testing organization with corresponding qualification for inspection. 3.8 Handing over inspection It refers to the activity that undertaker and completing party conduct the inspection and make a conform whether the construction can be continued. 3.9 Dominant item It refers to the inspection item dominating the quality and public interest in oil and gas construction engineering. 3.10 General item Inspection items except for the dominant items. 3.11 Sampling inspection It refers to the inspection by randomly selecting a certain amount of samples by inspection lot from site material, components, equipment or oil and gas construction engineering inspection items according to the required sampling scheme.
