To implement the party central committee and the state council on strengthening the comprehensive quality supervision requirements, further strengthening the construction of railway engineering construction materials, building components and equipment products in quality in the acceptance, to ensure the safety of railway construction project quality, now we will notify the following related matters.


First, we need to improve our thinking

Construction materials, components and equipment, product quality is the foundation of the railway construction project quality and guarantee, the use of substandard products, building materials, components and equipment will directly affect the engineering quality and service life, endanger people's life and property safety.Each unit should further improve the ideological understanding, attaches great importance to the railway construction project construction materials, building components and equipment product quality management and acceptance approach work, urge the relevant units to establish and perfect responsibility system, earnestly fulfill their respective responsibilities, improvement measures, regulate the behavior of quality.To strictly enforce the law ", "construction engineering quality management regulations on the administration of railway construction project quality supervision provisions" railway technology management regulations "and other laws and regulations and quality of" three-no problem behavior "rectification of action for the gripper, increase of railway construction project construction materials, building components and equipment product quality control and adhere to the principle of" after the first check with ", prevent due to use unqualified products and building materials, components and equipment for railway construction projects quality problems and hidden dangers.


Second, implement the acceptance criteria strictly

The construction materials, construction parts and equipment of railway construction shall be conducted in accordance with the regulations.Various contractors, especially construction and supervision unit strictly according to the provisions of the state and industry quality acceptance standard of construction materials, building components and equipment products in the acceptance work;In accordance with the regulations, the sampling plan of inspection batch quality inspection shall be formulated, and the inspection, verification and parallel inspection procedures shall be strictly self-examined, and the procedures for the inspection of the inspection shall be established.Involving the structure quality, use safety and function of the product, to conduct re-inspection shall be stipulated in the relevant professional engineering quality acceptance, and approved by supervision engineer to check.


Third, effectively implement principal responsibility

(1) the construction unit should strengthen the construction materials, building components and equipment supply management, strict product quality control in railway, establish product quality inspection system, in strict accordance with the relevant regulations and requirements, the supplier selection process and key point in the well off, give preference to products of good quality, high performance reputation, enterprise strength strong products manufacturers (suppliers), to ensure railway use products conform to the state and railway industry technical standards, to prevent counterfeit and shoddy products used in engineering construction.

(2) the design units to ensure the quality of design, the design files in the selected products, building materials, components and equipment you should indicate the type, model, performance and other technical indicators, its quality requirement shall conform to the relevant laws and regulations and industry norms.In addition to special requirements, the design unit may not specify the manufacturer or supplier.

(3) the construction unit should strengthen the construction materials, components and equipment product quality approach, the use of key links such as control, establish and perfect the management system and quality guarantee system, in the choice of suppliers, in the acceptance, quality detection and identification, storage, warehousing, issuing, accounting records and archival data summary to implement strict control system, to ensure the quality of construction materials, building components and equipment products meet the specifications and design requirements.It is important to strengthen the source control and pass the barrier of entry and inspection.Approach should be in accordance with the provisions, batch, after play for 100% of the amount of introspection, the evaluation of qualified rear can use, not suppliers inspection report or the commodity inspection report instead of the scene.In the process of product use, should strengthen the dynamic detection of controlling index, strengthen the use of change management, change of good to mark, material sources of change, material change, should be in accordance with the provisions, the relevant departments and units approval to use.

(4) supervision unit should give full play to play regulatory responsibilities, strengthen the construction materials, components and equipment in quality inspection work, strict quality management into the construction site.To standardize the sampling, deliver, witness and parallel detection work, in accordance with the relevant test items, frequency and required test and inspection, sampling when necessary to the approved inspection agency for testing.If the acceptance fails and the sampling test fails, it is necessary to immediately retire the appearance and prohibit the use of the relevant records in the project and keep the relevant records for the record.

(5) operation should strictly control units used into the railway product quality, with a focus on the acceptance of the link, supervision and spot check and acceptance is unqualified shall not be used of the products and product authentication failed.For the quality of the products discovered, the units concerned should be thoroughly cleaned up to ensure the safety of transportation.

(6) the relevant inspection and testing institutions shall conscientiously implement the quality of life responsibility system and truthfully reflect the test results.Every witness samples directly or the examination of railway construction project products, building materials, components and equipment must be issued in accordance with the provisions, witness signature test orders and must testify personnel accompany, otherwise all rejects.The relevant legal liabilities shall be borne for the results of false inspection.

Regional railway administration, engineering, quality control center should strengthen the railway engineering construction materials, components and equipment in acceptance work of supervision and inspection of product quality, increase the intensity of spot check, and carries on the sampling according to regulations, "urged enterprises joining into the strict product quality acceptance of the approach, to ensure the quality of railway engineering security.
