The goal of acceptable quality, cost, and time is a decisive challenge in every engineering development process. To be familiar with metrology requires choosing the best combination of techniques, standards, and tools to control a project from advanced simulations to final performance measurements and periodic inspections. This book contains a cluster of chapters from international academic authors who provide a meticulous way to discover the impacts of metrology in both theoretical and application fields. The approach is to discuss the key aspects of a selection of untraditional metrological topics, covering the analysis procedures and set of solutions obtained from experimental studies.
Metrological traceability of chemical measurement results means the establishment of a relation to metrological stated references through an unbroken chain of comparisons. This volume collects 56 outstanding papers on the topic, mostly published in the period 2000-2003 in the journal "Accreditation and Quality Assurance". They provide the latest understanding, and possibly the rationale why it is important to integrate the concept of metrological traceability including suitable measurement standards such as certified reference materials, into the standard measurement procedures of every analytical laboratory. In addition, this anthology considers the benefits to both the analytical laboratory and the user of the measurement results.
Analysis of Food Toxins and Toxicants consists of five sections, providing up-to-date descriptions of the analytical approaches used to detect a range of food toxins. Part I reviews the recent developments in analytical technology including sample pre-treatment and food additives. Part II covers the novel analysis of microbial and plant toxins including plant pyrrolizidine alkaloids. Part III focuses on marine toxins in fish and shellfish. Part IV discusses biogenic amines and common food toxicants, such as pesticides and heavy metals. Part V summarizes quality assurance and the recent developments in regulatory limits for toxins, toxicants and allergens, including discussions on laboratory accreditation and reference materials.
In the modern era of scientific and technological development, the role of measurements and metrology in scientific research is becoming more and more important due to the increase in the testing of various products. Moreover, requirements for the accuracy and reliability of measurement results are increasing significantly and their ranges are expanding. Improving measurement accuracy allows us to identify the shortcomings of certain technological processes and either eliminate them or reduce their influence. This leads to better-quality products and contributes to saving energy and other resources, as well as raw materials and materials. This book discusses relevant aspects of practical metrological activity to establish traceability of measurements while increasing their accuracy and reliability. It also presents procedures for the calibration and testing of measuring instruments.
Laboratory accreditation has assumed immense importance in recent years because of the need to assure the customer that the laboratory is capable of providing the valid test results reliably. ISO 17025:2017 Lab Quality Management System has become part of the requirement of all the laboratories, small to large. Over the years, ISO 17025:2017 Lab Quality Management System has evolved, as per the laboratory and customer requirements, and has become very important for improving laboratory systems and processes in order to sustain competitive advantages. This book focuses on requirements and key features of ISO 17025:2017 Lab Quality Management System such as risk-based thinking, PDCA approach, process management, and continual improvement. The readers would find it easier to understand the standard requirements and implement these in their work place.
This specification specifies the commonly used terms and their definitions in metrology. This specification applies to all tasks in the field of metrology. The related fields can also refer to it.
The ever-changing fields of science and technology have made huge leaps, thanks in part to improvements in measurements. Without metrology, these areas may not have experienced exponential growth. Developed by experts in the field as a comprehensive and practical reference, The ASQ Metrology Handbook, Third Edition provides a foundation for understanding metrology as well as calibration principles and practices. This handbook is ideal for not only metrology professionals, but also calibration professionals including calibration technicians and technologists, quality professionals, workers in testing laboratories, consultants, and instructors. Whether you are entering a new phase of your career field, investing in your own continuous improvement journey, training your fellow calibration practitioners, or preparing for ASQ’s Certified Calibration Technician (CCT) exam, this handbook provides the information, guidance, and knowledge to help you achieve your goals. New to this Third Edition: • A thorough explanation of ISO/IEC 17025:2017 • The 2019 Redefinition of the International System of Units • Updated and expanded chapters, including information about training and competency, software validation, statistics, decision rules and risk, uncertainty in measurement, mass and weighing, force, and chemical and biological measurements and uncertainties
This book describes the significance of metrology for inclusive growth in India and explains its application in the areas of physical–mechanical engineering, electrical and electronics, Indian standard time measurements, electromagnetic radiation, environment, biomedical, materials and Bhartiya Nirdeshak Dravyas (BND®). Using the framework of “Aswal Model”, it connects the metrology, in association with accreditation and standards, to the areas of science and technology, government and regulatory agencies, civil society and media, and various other industries. It presents critical analyses of the contributions made by CSIR-National Physical Laboratory (CSIR-NPL), India, through its world-class science and apex measurement facilities of international equivalence in the areas of industrial growth, strategic sector growth, environmental protection, cybersecurity, sustainable energy, affordable health, international trade, policy-making, etc. The book will be useful for science and engineering students, researchers, policymakers and entrepreneurs.
