What are the quality assurance systems and measures?
Quality assurance systems and measures:
Project construction quality objectives.
be clear and meet the requirements of the overall quality objective. The decomposition of project quality objectives is mainly carried out from the perspective of time and space.
project construction quality plan.
it should be compiled according to the enterprise's quality manual and project quality objectives. The project quality plan can be divided into construction quality work plan and construction quality cost plan according to the content.
ideological guarantee system.
With the ideas, viewpoints and methods of total quality management, all staff can truly establish a strong quality consciousness.
organization guarantee system.
establish and improve organizations at all levels, with division of responsibilities, so as to give priority to prevention and combine prevention with inspection to form an organic whole with clear tasks, responsibilities, authorities, mutual coordination and mutual promotion.
job guarantee system.
quality control is carried out through construction preparation stage, construction stage and completion acceptance stage.
Note:
Quality assurance means should adhere to the combination of management and technology, that is, repeatedly check whether the enterprise has sufficient technical assurance ability and management assurance ability, both of which are indispensable.
quality assurance system is not synonymous with institutionalization and standardization, and should never be a written and documented quality assurance system.
quality information management is the driving force for the normal operation of the quality assurance system. Without quality information, the system is static and only a formal system.
the depth and breadth of the quality assurance system depends on the quality objectives, and there is no fixed quality assurance system that can adapt to different quality levels.
a quality assurance system is established mainly for products or services provided, and can also be established for working procedures (or processes).
What are the commonly used quality control measures in the laboratory?
1. External quality control
External quality control, as its name implies, is a way to ensure the test results by using quality control means outside the laboratory, which is generally divided into capability verification and inter-laboratory comparison.
1.1 competence verification
competence verification refers to the evaluation of the competence of participants according to the pre-established criteria by comparison between laboratories, which is one of the necessary conditions for accredited institutions to join and maintain the international mutual recognition agreement (MRA) and an important and effective external quality control activity of laboratories.
every year, the laboratory can check the annual proficiency testing plan on the official website of China National Accreditation Committee for Conformity Assessment (CNAS) and select the items to participate in the proficiency testing. Laboratories participate in the verification and receive test samples by way of registration, and feed back to the organization of capacity verification within the specified time after completing the test according to the specified scheme. The organization of capacity verification issues a capacity verification result report after statistical analysis according to the test results of all participating laboratories, and the laboratory should evaluate its testing capacity according to the result report. The evaluation methods of capability verification include: 1. Evaluation parameters (En) of magnitude comparison: if | en | ≤ 1, it is satisfactory and passed; If | en | > 1, dissatisfied, not passed. 2. Test comparison evaluation parameter (z): | z | ≤ 2, satisfactory and passed; | z | ≥ 3, dissatisfied and failed; 2< ｜Z｜< 3, suspicious.
when the results of competency verification are unsatisfactory, the laboratory should deeply analyze the reasons, implement corrective measures and verify the effectiveness of the measures; When suspicious results appear, the laboratory should analyze the reasons and take corrective measures when necessary according to its severity and influence scope.
Participating in proficiency testing is a very effective external quality control method, which can not only determine and monitor the ability and sustainability of laboratory testing, but also effectively identify the problems existing in the laboratory. However, due to the restriction of the annual plan, sometimes some testing items in the laboratory are out of the plan and the ability cannot be confirmed, so it is necessary to carry out inter-laboratory comparison to supplement it.
1.2 interlaboratory comparison
interlaboratory comparison refers to the organization, implementation and evaluation of the same or similar test samples by two or more laboratories according to the pre-specified conditions, so as to identify the problems existing in the laboratories and the differences between the laboratories.
Generally, there are two ways to carry out inter-laboratory comparison, one is to organize independently, and the other is to participate as a participant. As the organizer, the laboratory should first choose a suitable comparison laboratory. In order to ensure the credibility of the comparison results, it is suggested to choose a laboratory that has been recognized by CNAS, metrological certification or authoritative in the industry as far as possible; The laboratory should also make a reasonable comparison plan, which should include the methods adopted, test items, data analysis and processing methods, sample quantity and necessary information, experimental requirements, test results and other contents, and reach an agreement with the participating laboratories; Finally, the organizer prepares the comparison report according to the test results, and makes clear the conclusion of the comparison, the problems to be improved and the improvement measures.
through the comparison between laboratories, the laboratory can find out the existing problems and the differences with other laboratories in time, so as to find out the reasons and improve them in time. Compared with capability verification, it is more flexible and can be used as a common means of external quality control in laboratories.
2. Internal quality control
Internal quality control refers to the quality control carried out by the laboratory with its own resources to ensure the effectiveness of the test results, which generally includes methods such as using standard monitoring, personnel comparison, instrument comparison, method comparison, sample re-testing, and analyzing the correlation of results with different characteristics of articles.
2.1 personnel comparison
refers to the ability comparison between laboratory testing technicians. Different testing technicians use the same instrument, use the same method and test the same special substance under the same testing conditions, and evaluate the obtained data. It can be used as a means to verify the technical ability of new employees after training, and can also be carried out in laboratories with multiple inspectors.
2.2 instrument comparison
refers to the comparison between testing instruments. Different testing instruments, the same tester, the same method and the same testing conditions are used to test the same testing sample, and the obtained data are evaluated to determine the differences between the instruments. When the laboratory has different equipment, the method of instrument comparison can be used to carry out quality control, especially when one instrument obtains satisfactory results in capacity verification, which can be used to measure the credibility of other instruments.

what are the quality control measures for building materials?
1. Quality control of materials before entering the site
Read carefully the engineering design documents, construction drawings, construction contracts, construction organization design and other documents related to engineering materials, and be familiar with the provisions and requirements of the documents on material varieties, specifications, models, strength grades, manufacturers and trademarks.
carefully check the quality standards of the materials used, understand the basic properties, application characteristics and scope of application of the materials, and provide reasonable suggestions to the owner on the selection of main materials, equipment and components when necessary. Master the material information and optimize the supplier. Grasping the information of material quality, price and supply capacity, and choosing reliable suppliers can obtain good quality and low price material resources, and help to ensure the engineering quality and reduce the engineering cost. Provide timely information on the materials supplied by the owner; For the materials supplied by the contractor, the order declaration should be examined and demonstrated in time, and the order can only be placed after being reported to the owner for approval.
2. Quality control of materials entering the site
The material list must be consistent. When materials enter the site, it is necessary to check whether the actual situation of the materials present is consistent with the required materials in terms of variety, specification, model, strength grade, manufacturer and trademark, and whether the production number or batch number, model, specification and production date of the products are consistent with the product quality certificate. In case of any inconsistency, it is necessary to request a return or request the supplier to provide materials. Materials with unclear marks can be returned (or sampled). All kinds of raw materials, semi-finished products and components entering the construction site must have corresponding quality assurance materials. Including: production license or use license; Product certificate, quality certificate or quality test report. The certificate of conformity must be stamped with the red seal of the production unit or supplier, and indicate the factory date, production batch number and factory certificate.
3. Quality control after materials enter the site
All raw materials, semi-finished products and components used in the project.
