1 General Provisions
1.0.1 This standard is formulated with a view to strengthening constructional quality management, unifying standard for constructional quality acceptance and ensuring constructional quality of high-speed railway signaling engineering.
1.0.2 This standard is applicable to the constructional quality acceptance of newly-built 250~350km/h high-speed railway signaling engineering. The constructional quality acceptance of signaling engineering for passenger dedicated line and inter-city railway in speed less than 250km/h may also refer to this standard.
1.0.3 The construction parties concerned of high-speed railway signaling engineering shall establish and improve quality assurance system, conduct whole-process control over the constructional quality of engineering, and implement lifelong quality accountability system to management, technical and operating personnel.
1.0.4 The construction parties concerned of high-speed railway signaling engineering shall standardize management system, personnel allocation, site management and process control, and implement construction and management requirements such as quality, safety, construction period, investment returns, environmental protection and technological innovation.
1.0.5 The construction of high-speed railway signaling engineering shall fully comply with the national laws and regulations and the relevant technical standards and be in strict accordance with the design documents, the constructional quality shall meet the requirements for use functions, safety and quality performance of system, and the engineering shall be ensured of normal use during the design service life.
1.0.6 Main equipment and apparatuses adopted in high-speed railway signaling engineering shall meet those specified in the relevant national and professional standards and admittance for railway industry.
1.0.7 Requirements for constructional quality as stated in the contract documents and engineering technical documents adopted in construction of high-speed railway signaling engineering shall not be inferior to those specified in this standard; otherwise, these requirements shall prevail.
1.0.8 During construction of high-speed railway signaling engineering, efforts shall be made to implement sustainable development strategy of the national economy, make rational utilization of resources and properly carry out environmental protection and water & soil conservation.
1.0.9 The construction of high-speed railway signaling engineering shall comply with the current relevant labor protection laws and regulations of the nation to ensure health of constructors and to avoid or reduce harm.
1.0.10 For the construction of high-speed railway signaling engineering, mechanized, industrialized, specialized and informationized construction measures shall be positively adopted.
1.0.11 For the construction of high-speed railway signaling engineering, advanced, mature and scientific inspection and testing measures shall be adopted. The quality inspection data must be authentic and reliable and overall reflect the engineering quality. The methods, instruments and equipment adopted shall meet those specified in the relevant technical standards, the instrument performance shall meet the requirements of quality inspection, and the quality inspectors shall possess the specified qualifications.
1.0.12 All the quality inspection reports, inspection and acceptance records and other technical management data for construction of high-speed railway signaling engineering shall be timely filled in as required and shall strictly comply with the responsible person signature confirmation system. The filing, reorganization and preservation period of constructional quality acceptance data shall meet the requirements of relevant provisions.
1.0.13 The construction and acceptance personnel of high-speed railway signaling engineering shall pass necessary training and examination before taking up the post.
1.0.14 In addition to this standard, the constructional quality acceptance of high-speed railway signaling engineering shall also comply with those specified in the current relevant standards of the nation.
