إخوتي الكرام
السلام عليكم و رحمة الله تعالى و بركاته
عيدكم سعيد و كل عام و أنتم بخير.
حتى نتمكن من استعاب أهمية مجال القياسات الصناعية ( ) في مختلف مجالات حياتنا الاقتصادية، الصناعية ، السياسية و حتى العادية أرى أن نقوم بعرض المؤتمرات التي تقام هنا و هناك و التي تختص بعلم القياسات و تطبيقاته في مختلف المجالات و ما هي أهم الأفكار المتداولة هناك عسى مجتمعاتنا تعي أهمية هذا العلم مع أن دستورنا المنزل على على خاتم الأنبياء و المرسلين يحثنا بصراحة على القسط في الكيل و الموازين و عدم إخسار فيهما و هذا هو لب علم القياس.... إن شاء الله سيكون لنا موضوع حول هذه النقطة بالذات.
و الآن كبداية لعرض التجارب الناجحة للدول الغربية في هذا المجال، أعرض عليكم بعض الملخصات التي تم تقديمها خلال مؤتمر علم القياس لسنة 2005 المنعقد في أمريكا:

Management, Measurement and
the Metrology Handbook
Jay L. Bucher
Abstract - No matter the project, program, or problem; if timely, effective results are desired…one should be making measurements and acting on the data throughout the management process. Such was the case with writing The Metrology Handbook. With eight coauthors located between Wisconsin and Texas, Georgia and California, and a few points in between, this could have been a management nightmare. However, by assigning areas of responsibility, time lines for completion of writing, reviewing, and commenting, and closely monitoring each of these processes, the impossible became the probable, and our aggressive deadlines were met. Even in the face of non-performers, and when participation was interrupted by job and family requirements, alternative solutions and switch hitters stepped up to the plate. Should this be considered a piece of cake? Not by anyone’s imagination. This paper explains what processes were put in place, how they were managed and the obstacles that were overcome. Included are some ‘lessons learned’ that might help others as they try to “herd a group of cats”.
Metrology Education and Training:
A Necessity, After Eight Years
Emil Hazarian
NSWC Corona Division
Corona, CA
Abstract - The implications of over and under qualifications in metrology are discussed in relation with today and future demand for skilled, certified Metrologists, both at the managerial and operational level. The differences between formal education and specialized training are analyzed as a response for creating a professional probity environment. A higher exposure and transparency of the metrology field is advocated, with the focus on training formalization. Changes and new trends in metrology training, such as those inferred by computerization are presented. An update look at the educational institutions and training expertise available domestically and internationally is undertaken.
ASQ Measurement Quality Division Sponsored Session
Management, Measurement, and The Metrology Handbook

Session Developer: Dilip A. Shah, Chairman

A piece of cake? Far from it. This paper explains what processes were put in place, how they were managed, and the obstacles that needed to be overcome. Included are some lessons learned that might help others as they try to “herd a group of cats”.
The ASQ Certified Calibration Technician Exam Report
By Dilip A. Shah
Abstract: The ASQ’s Certified Calibration Technician (CCT) Exam is now two years old and over 250 candidates have passed the exam since its first offering in June of 2003. This presentation provides the report on the exam progress, industry acceptance and the body of knowledge covered. The Measurement Quality Division’s involvement with the exam sponsorship, development and exam volunteer opportunities are discussed.
The ASQ Certified Calibration Technician Panel Discussion
By Dilip A. Shah, Jay Bucher, others
Abstract:
Following the CCT Exam report, the panel discussion will take place that will provide an opportunity for the audience to ask about the exam specifics, statistics and concerns.
Everything You Need To Know About ISO 17025
Benny Smith
www.inch-worm.com
Abstract - Have you ever read the text of ISO 17025, “General Requirements for the Competence of Testing and Calibration laboratories?” If so, this paper will reinforce your understanding and provide insight into some subtle issues that you may not have considered. If you have never read the standard, perhaps out of fear or procrastination, this paper will de-mystify it and give you the understanding that you need to make decisions about the standard within your organization. It will also dispel some myths that have grown up around the standard.
Importance of Measurement Uncertainty in Calibration
and Conformity Testing of Measuring Instruments
Klaus-Dieter Sommer
Thuringian State Authority of Metrology and Verification (LMET)
Ilmenau, Germany
Bernd Siebert
Manfred Kochsiek
Physikalisch-Technische Bundesanstalt (PTB)
Braunschweig, Germany
Abstract: Particularly in legal metrology, the measurement error of a measuring instrument may be regarded as the commonly used output quantity of calibration. In accordance with the modern approach to the expression of uncertainty, this instrumental error is to be represented by its best estimate and by the associated measurement uncertainty that, consequently, is regarded as the uncertainty associated with the (expectation value of the) calibration result. This uncertainty is to be stated in calibration certificates. Its evaluation is based on the knowledge of all relevant (input) quantities and of the calibration process expressed by the so-called model equation [1].
The (expectation value of the) calibration result, together with its associated measurement uncertainty, form the basis for quantitative conformity decisions as to whether a measuring instrument conforms with (legally or otherwise) prescribed error limits / tolerances. The way that is chosen to take the measurement uncertainty into consideration in these conformity decisions - such as, for example, deciding in accordance with the standard ISO 14253-1 - has an important impact not only on the accuracy that can be achieved subsequently when conformity-tested instruments are being used [2] but also on the producer / consumer risk of wrongly tested instruments.
The legal and industrial concepts used most commonly for quantitative conformity decisions will be analysed, along with their effects on consumer risk, on the uncertainty contribution of the tested instruments in use, and on the measurement capability of instruments employed in the control of production processes [3].
Based on ongoing OIML work, the paper will recommend guidelines for a harmonized treatment of the measurement uncertainty in legal conformity decisions, such as in verification, type approval and inspection, including the provision of reasonably substantiated tolerance-uncertainty ratios. The paper extends previous work of the authors [1, 2, 3]
