And assessment of proficiency testing schemes in the planning, implementation, analysis, reporting and effectiveness of the procedures. ② identification and evaluation by other institutions and organizations of the inter-laboratory comparison. ③ Evaluation of the capability of participating laboratories with the ability to verify the results. ④ the results obtained on proficiency testing program, and how these findings and laboratory evaluation with other aspects of the use of technology to the assessment of laboratory capacity to provide advice of any institution. ⑤ participants to the problems advise. ⑥ coordinator and the participants to resolve disputes between. If proficiency testing agency personnel have been able to accomplish the above tasks, you Needless to organize advisory group. 3.3 The main points of the establishment of proficiency testing schemes (1) statistical design of the proficiency testing program to select and conduct appropriate statistical design is essential, using statistical models and data analysis techniques should be documented, including the general content related to detection accuracy, required confidence level, the number of participating laboratories, the number of samples and for each sample the number of repeated testing, the use of the specified value,[link widoczny dla zalogowanych], outlier identification methods, the report contains information. (2) Preparation of test items should normally be the coordinator (proficiency testing providers) undertake the preparation of test items, of course, can be outsourced, but outsourcing organization should have a uniform and stable preparation of test items and assessment capabilities and qualifications to be recognized . And detection of any items relating to, may affect the integrity of inter-laboratory comparison of the conditions, such as uniformity, stability,[link widoczny dla zalogowanych], sampling, may be damaged in transit in the circulation, and the surrounding environmental conditions such as in the planning and design should be fully consideration. (3) the management of test items taken the first test items, randomized, shipping, receiving,[link widoczny dla zalogowanych], identification, labeling, storage and disposal process should be documented. Secondly, proficiency testing provider or coordinator should develop items for inspection uniformity and stability of the program files, and distributed to participating laboratories in the prior should be the test of homogeneity, to confirm detection of objects is uniform, during which the difference was not will participate in the results of laboratory evaluation of impact. Capacity should also be verified to ensure that the entire implementation process, testing items sufficiently stable and will not produce significant changes in the stability test the stability of the prescribed time intervals tested to confirm the detection of items offered is stable. Note also plans to distribute the test items or materials,[link widoczny dla zalogowanych], usually in the nature of the 13 participating laboratories should test items or materials often similar. (4) method / procedure selection generally participants in the choice of methods should be routine procedures used the same; if the participant freedom to choose the method used, the coordinator should be asked to participate in providing the methods used the details to take advantage of the participants结果 be considered and compared, and this method comment; However, in some cases, coordinator (proficiency testing providers) can indicate the participants using a particular method, these methods are often adopted by national or international standards on method, and has adopted appropriate procedures (such as collaborative trial) of the confirmation. In this case, because the participants will use the same methods. Therefore, all participants the results more comparable, favorable evaluation of their ability. (5) Data processing equipment proficiency testing activities, regardless of what equipment should be able to enter all necessary data for statistical analysis and provide timely and effective results. Check data entry procedures should be implemented, all software should be validated, support and backup. Data file storage and security should be controlled. (6) The development of proficiency testing schemes to ensure that proficiency testing schemes to adapt to modern technology and scientific development requires the introduction of new samples and new methods, new procedures. According to the results of such programs the ability of each laboratory to early conclusions must be cautious as to the purpose of proficiency testing, when the new testing materials, insufficient showing homogeneous or stable, not being graded or measured points, you can temporarily be evaluated. (Continued) (Continued from p. 362) 5 Conclusion force wrench back to zero because the test failed, elastic component materials exceeded the standard non-metallic inclusions and banded structure, as a result of improper heat treatment and micro-generation cracks, surface decarburization and heart Ministry of serious ferrite. Taken to improve the measures (including strict control of raw materials and improve the heat treatment process organization), the guarantee of product quality. * 376 * Thanks: Tests have been Xuyan Lin, Tang Guangping comrades enthusiastic support and great help, to express my heartfelt thanks.
