BS ISO 7078:2020 pdf free.Buildings and civil engineering works —Procedures for setting out, measurementand surveying — Vocabulary.
This document defines terms that are commonly used in procedures for setting out, measurement andsurveying in buildings and civil engineering works.
Normative references:There are no normative references in this document.
measurement:operation that has the object of determining the value of a quantity [SOURCE: ISO 6707-1:2017,, modified — Note 1 to entry has been omitted.] setting outlayout, USlaying out,US establishment of marks and lines to define the position and level of the elements for the constructionwork so that work can proceed with reference to them [SOURCE: ISO 6707-2:2017,3.3.13]
metrology:science of measurement (3.1.1) and its application
Note 1 to entry: Metrology includes all theoretical and practical aspects of measurement,whatever themeasurement uncertainty and field of application.
[SOURCE: ISO Guide 99:2007,2.2]
geodesy:science of measurement(3.1.1) on or in the vicinity of the ground to determine form, dimensions andthe distribution of mass and fields of gravity on the earth or parts of it.indication:quantity value provided by a measuring instrument(3.1.7) or a measuring system(3.1.19)
Note 1 to entry: An indication may be presented in visual or acoustic form or may be transferred to anotherdevice.An indication is often given by the position of a pointer on the display for analogue outputs, a displayedor printed number for digital outputs, a code pattern for code outputs,or an assigned quantity value formaterial measures.
Note 2 to entry: An indication and a corresponding value of the quantity being measured are not necessarilyvalues of quantities of the same kind.
[SOURCE: ISO/IEC Guide 99:2007,4.1]3.1.13
measurement result:set of quantity values being attributed to a measurand (3.1.6) together with other availablerelevant information
Note 1 to entry: A measurement result generally contains “relevant information” about the set of quantity values,such that some may be more representative of the measurand than others.This may be expressed in the form ofa probability density function (PDF).
Note 2 to entry: A measurement result is generally expressed as a single measured quantity value and ameasurement of uncertainty. If the measurement uncertainty is considered negligible for some purpose, themeasurement result may be expressed as a single measured quantity value.In many fields, this is the commonway of expressing a measurement result.[SOURCE: ISO/IEC Guide 99:2007,2.9, modified— NOTE 3 has been omitted.]3.1.14
measurement standard realization of the definition of a given quantity value and associated measurement (3.1.1)uncertainty,used as a reference.BS ISO 7078 pdf download.
