To achieve this goal, the international standard ISO 13528:2022 presents four performance statistics and one of them is the <i>z</i> score. Some researchers have proposed an alternative approach for proficiency testing scheme interpretation based on an analysis of variance method. This short communication presents residual analysis to choose an appropriate analysis of variance model for proficiency testing interpretation when the assigned value is obtained by consensus value among participants. The analysis of variance approach was compared with <i>z</i> score to assess the performance of interlaboratory comparison for determining the amount of NO<sub><i>x</i></sub> present in vehicle emissions. Preliminary results indicate that the conclusions obtained by both methodologies differ for one of the participating laboratories. This occurs due to violation of the homoscedasticity assumption which is not considered when using the <i>z</i> score. On the other hand, residual analysis can provide such information and feasible generalized least squares can deal with heteroscedasticity .</p></div>","PeriodicalId":454,"journal":{"name":"Accreditation and Quality Assurance","volume":"28 4","pages":"183 - 186"},"PeriodicalIF":0.9,"publicationDate":"2023-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00769-023-01548-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"5119108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The safety of workers, the accuracy and reliability of laboratory results, issues of financial sustainability as well as the protection of the environment play an important role in decision-making in both industry and services. In order a laboratory to be considered as reliable, safe, and therefore competitive, it is recommended to comply with the requirements of international standards and other regulatory documents as well as to use tools and risk management procedures. In this paper, information is summarized concerning the terms “risk” and “risk management” which are then approached through the latest ISO 9001, ISO/IEC 17025, and ISO 14001 standards. The process of risk management based on the ISO 31000 standard is described, the options for treatment and the techniques that can be applied in the risk management process based on the latest ISO 31010 standard are grouped and indicated. Additionally, information from the literature is referred to the reasons that led the laboratories to integrate in their quality system risk management techniques, the most common mistakes that occur in the various phases of laboratory tests, their causes, their consequences as well as the proposed treatments. The aim of this work is to highlight significant challenges concerning the need to implement management procedures in the daily routine, to warn, raise awareness and inform about existing ways of risk management that can be implemented, methodologically and technically, to laboratories, under internationally recognized and updated standards.</p></div>","PeriodicalId":454,"journal":{"name":"Accreditation and Quality Assurance","volume":"28 4","pages":"167 - 179"},"PeriodicalIF":0.9,"publicationDate":"2023-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00769-023-01540-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4508915","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of considering both the technical and managerial aspects of this process is highlighted.

Despite the importance of “metrological networks” for encouraging a quality culture and accreditation in Brazil, greater rigor may be needed regarding the demand for systematic evidence of sustainable compliance and maturity of the management system.

This paper describes the design and implementation of an information system for electronic reference material documents. Based on the varieties and batches of reference materials, the coding rules for two-dimensional codes of reference materials are formulated and employed to uniquely manage each unit of reference materials. A complete process of document template making, review and release has been designed as part of the manufacturing process for reference materials. Using the interface development function of major social media platforms, the method of generating and previewing documents by scanning the QR code on the label of a reference material with a mobile phone is designed. Users may view and download all electronic documents generated by their scanning through the special document management website page. The system has been implemented and is currently in use.

The 1R6F certified reference cigarette for analytical testing was developed to be typical of an American blend cigarette. The cigarettes have been used in proficiency testing (PT) schemes under the supervision of the CTRP since 2016 for a variety of parameters. Data were compared from 8 rounds of PT schemes submitted by participating laboratories, which include various international stakeholders comprised of academic institutions, federal research/regulatory laboratories, tobacco product manufacturers, and independent contract testing laboratories. Evaluation of the datasets for harmful and potentially harmful constituents (HPHCs) within the mainstream smoke of the 1R6F certified reference cigarette included tobacco-specific nitrosamines (TSNA), tar, nicotine, and carbon monoxide (TNCO), and Benzo[<i>α</i>]pyrene (B<i>α</i>P). Of the datasets evaluated, less than 5 % resulted in either a warning or alert, and less than 2 % resulted in an alert. Comparisons across multiple PT rounds revealed no significant differences in the consensus means of the tested parameters. Evaluation of data submitted by participating laboratories for multiple proficiency test rounds shows that the 1R6F certified reference cigarette is an acceptable material as a control reference for the analysis of HPHCs which is imperative since some stakeholders may be required to participate in, and receive satisfactory results, from PT for accreditation purposes.</p></div>","PeriodicalId":454,"journal":{"name":"Accreditation and Quality Assurance","volume":"28 2","pages":"69 - 76"},"PeriodicalIF":0.9,"publicationDate":"2023-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s00769-023-01534-1.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"4549308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
