This document gives names, symbols, definitions and units for quantities of mechanics. Where
appropriate, conversion factors are also given.

ISO 80000-11:2019 gives names, symbols and definitions for characteristic numbers used in the description of transport and transfer phenomena.

This document presents methods for determining the critical value of the response variable and the minimum detectable value in Poisson distribution measurements. It is applicable when variations in both the background noise and the signal are describable by the Poisson distribution. The conventional approximation is used to approximate the Poisson distribution by the normal distribution consistent with ISO 11843‑3 and ISO 11843‑4. The accuracy of the normal approximation as compared to the exact...view more

1.1 This document is concerned with polynomial calibration functions that describe the relationship between a stimulus variable and a response variable. These functions contain parameters estimated from calibration data consisting of a set of pairs of stimulus value and response value. Various cases are considered relating to the nature of any uncertainties associated with the data. 1.2 Estimates of the polynomial function parameters are determined using least‐squares methods, taking account of ...view more

Background noise exists ubiquitously in analytical instruments, whether or not a sample is applied to the instrument. This document is concerned with mathematical methodologies for estimating the minimum detectable value in case that the most predominant source of measurement uncertainty is background noise. The minimum detectable value can directly and mathematically be derived from the stochastic characteristics of the background noise. This document specifies basic methods to — extract the st...view more

ISO 18674-3 applies to the measurement of displacements across a measuring line by means
of inclinometers carried out for geotechnical monitoring.
ISO 18674-3 also refers to deflectometers (see Annex B) to supplement inclinometers for the
determination of horizontal displacements across horizontal measuring lines.

IEC 62828-1:2017 establishes a general framework for defining reference conditions and test procedures applicable to all types of industrial and process measurement transmitters (PMTs) used in measuring and control systems for industrial process and machinery. These reference test conditions are divided into “standard reference conditions”, which apply when determining the accuracy of measurement, and “ambient and process reference conditions”, which are used to assess the influence of external ...view more

This document gives guidance for
— evaluation of measurement uncertainties using data obtained from studies conducted in accordance
with ISO 5725-2, and
— comparison of collaborative study results with measurement uncertainty (MU) obtained using
formal principles of uncertainty propagation (see Clause 14).
ISO 5725-3 provides additional models for studies of intermediate precision. However, while the same
general approach may be applied to the use of such extended models, uncertainty evalu...view more
