Analytical quality assurance (aqa)
| Глоссарий по стандартизации, контролю и управлению качеством |
Used with charts of operating specifications (opspecs charts) to indicate the level of assurance for detecting critical sized errors. for example, 90% aqa(se) means there will be at least a 90% chance of detecting the critical systematic error when operating within the allowed limits for imprecision and inaccuracy for the given control rules and total number of control measurements (n).

Specifications, английский
- A document that explains all material and construction requirements of the bridge structure to be constructed, usually used by engineers or architects in the planning stages of construction.
- A detailed description of a print order.
- A part of the contract documents contained in the project manual consisting of written descriptions of a technical nature of materials, equipment construction systems, standards, and workmanship. under the uniform system, the specifications comprise sixteen divisions. specific gravity 1. the ratio of the density of a substance to the density of a reference material (usually water for liquids and air for gases). 2. as applied to a gas piping system, the ratio of the weight of gas of a given volume to the weight of the same volume of air, both measured under the same conditions.
- Отвечать требованиям технических условий meeting:
- Соответствие состава бетонной смеси требованиям технических условий ~ of water for making concrete пригодность воды для приготовления бетонной смеси suite: ~ of rooms 1. анфилада комнат 2. номер- люкс (в гостинице) wc ~ укомплектованное оборудование санузла
- Чертежи и технические условия (техническая документация проекта)
- Спецификации
Systematic, английский
Common to all businesses.
Imprecision, английский
- “the random dispersion of a set of replicate measurements and/or values expressed quantitatively by a statistic, such as standard deviation or coefficient of variation.” [clsi] ifcc has recommended that the mean value and number of replicates should also be stated, and the experimental design described in such a way that other workers can repeat it. this is particularly important whenever a specific term is used to denote a particular type of imprecision, such as within-run, within-day, day-to-day, total, or between-laboratories.
- Неточность. см. precision (прецизионность).
- Неточность ров частиц, осаждаемых на каждом предметном стекле, зависит от диаметра отверстия и скорости движения газа.
- Неточность. см. precision — точность.
Inaccuracy, английский
- "numerical difference between the mean of a set of replicate measurements and the true value. this difference (positive or negative) may be expressed in the units in which the quantity is measured, or as a percentage of the true value" [ifcc]. we use the term biasmeas to describe the average systematic difference between a measurement procedure and a comparative method and express it in percent on opspecs charts..
- Неточность, погрешность
- Неточность
- Неточность; погрешность
Measurement, английский
- Set of operations having the object of determining a value of a quantity (1)
- Измерение. система мер.
- Измерение; замер
- The size, length, etc. of something which has been measured
- Измерение
- Обмер
- Оценка
- Измерение dust ~ измерение концентрации пыли
- Измерение. комплекс операций, имеющих целью определение значе-ния величины [32].
- The process of ascertaining the attributes, dimensions, extent, quantity, degree or capacity of some object of observation and representing these in the qualitative or quantitative terms of a data language. any empirical pursuit that places the observer outside his object of observation must consider measurement the fundamental process through which scientific constructs or models are linked to reality (->index, ->symptom). otherwise measurement is only one section in a circular process of computing a stable form. the traditional levels of measurement are nominal, ordinal, interval and ratio scales.
- The magnitude of the property of an object calibrated against one or more units of measure.
- Измерение. комплекс операций, имеющих целью определение значения величины [32].

Analytical quality requirement, английский
Used here to refer to a quality requirement in the form of an allowable total error (tea). often defined on the basis of proficiency testing criteria for acceptable performance, such as the clia requirements for regulated analytes.
Analytical measurement range, amr, английский
Defined by cap (college of american pathologists) as the range of numeric results a method can produce without any special specimen pre-treatment, such as dilution, that is not part of the usual analytic process. same as reportable range in clia terminology.
