(a) quality control of personnel
Laboratory personnel is the core of the work to be carried out, the management of personnel has become the basic work of quality control. Laboratory quality control personnel quality and competence and business level is to ensure the effectiveness of the test work is the key to improve the quality of quality control personnel to play their role in monitoring. First of all, the quality control personnel to master the scientific detection methods, the latest developments in technology to fully understand; secondly, the laboratory personnel should continue to improve their technical skills and quality of culture, learn to use advanced equipment for testing work, clear the importance of their own work; once again, the quality control personnel to use their spare time to continuously improve themselves, improve their ability to update their knowledge system, to master the latest developments in the product; finally, the laboratory staff to improve the quality of ability and business level is the key to ensure the effectiveness of testing work, to play their role in monitoring. Finally, the relevant units of the laboratory should adhere to the implementation of the "introduction and go out" coexisting development strategy, and actively introduce advanced equipment and excellent personnel, and send capable internal workers to foreign exchanges to learn and broaden their horizons. The laboratory should also do a good job of training and assessment of personnel to ensure that their level of competence to meet the high requirements of the laboratory.
(ii) equipment and measuring instruments quality control
Instrumentation and measuring instruments are the most basic tools for testing work, its degree of integrity and accuracy will directly affect the accuracy of the test results. In the daily facilities testing should be strictly in accordance with the equipment management program in the "procurement - acceptance - use - maintenance - scrapping" process for the operation. First of all, focus on the traceability of the equipment, the state has clearly defined measurement and calibration of instruments and equipment should be in strict accordance with the calibration cycle / calibration intervals for verification / calibration; for no calibration procedures or can not be calibrated equipment, the need to prepare self-calibration specifications for calibration, and make a good record of calibration. Secondly, period verification of equipment is also an important quality control method. The use of a higher level of measurement standards, certified substances for verification; the use of the same accuracy of the measurement standard for equipment comparison; in the repeated measurements, the choice of stability and sensitivity are better samples for evaluation; the use of equipment and instruments for self-calibration of their own procedures.
(C) the quality control of the sample
The overall performance of the test object is based on the results of the sample quality control to judge, it can be seen that the sample quality control is the key to the quality control of the laboratory work is the focus of laboratory work. First of all, the sample should pay attention to the scientific nature of the selection, the laboratory in the testing of samples should be developed sampling method, and its accurate judgment and scientific control; second, the sample should be scientifically managed, the laboratory should be samples of the reception, storage, collocation, transmission, processing and other processes under strict management to ensure that the samples to maintain the integrity of the original state.
(D) quality control of the testing process
1. Preparation for testing
The state of the sample should be checked before the test to see if it is intact; whether the function and accuracy of the instrumentation meets the requirements; whether the environmental conditions meet the technical requirements of the test.
2. Ensure the scientificity and validity of the testing method
Quality control of the method can ensure that the procedures of laboratory testing activities have rationality and comply with the testing standards. Therefore, the laboratories should adopt the national unified promulgated standards for testing, and regularly search for new, to ensure the effectiveness of the use of standards. In addition, non-standard methods, including methods developed by laboratories, methods developed by equipment manufacturers, methods published by well-known technical organizations, the laboratory should be confirmed.
3. Detection of original records and data processing
In order to ensure the accuracy, validity and scientific testing results, the original records are very important. To truly record the detection of a variety of data, including enough information to determine the uncertainty of the factors affecting the test to ensure that the test as close as possible to the original conditions can be reproduced. To correctly apply the measurement uncertainty to assess the test results, so that the results of the complete expression of the test; correctly carry out the effective number of modification and arithmetic; reduce the measurement error, increase the number of parallel measurements, eliminate the systematic error of the measurement process.
(D) quality control of environmental conditions
Laboratory in the testing process of the operating conditions have high requirements, quality control of environmental conditions has become a key technology to enhance the level of testing. Testing and calibration site equipment, environmental conditions are important elements of the conditions of quality control. Once found in the quality control does not meet the standard conditions, to be immediately adjusted, and in the specific work carried out in the implementation of safety protection measures, so as to ensure that the laboratory environment to meet the actual needs.
