DIN EN ISO 80000-5:2013-08 EN ISO 80000-5:2013 (E) 3 Introduction0.1 Arrangements of the tablesThe tables of quantities and units in this International Standard are arranged so that the quantities arepresented on the left-han

25、d pages and the units on the corresponding right-hand pages.All units between two full lines on the right-hand pages belong to the quantities between the corresponding fulllines on the left-hand pages.Where the numbering of an item has been changed in the revision of a part of ISO31, the number in t

26、hepreceding edition is shown in parentheses on the left-hand page under the new number for the quantity; a dashis used to indicate that the item in question did not appear in the preceding edition.0.2 Tables of quantitiesThe names in English and in French of the most important quantities within the

27、field of this InternationalStandard are given together with their symbols and, in most cases, their definitions. These names and symbolsare recommendations. The definitions are given for identification of the quantities in the International System ofQuantities (ISQ), listed on the left-hand pages of

28、 the table; they are not intended to be complete.The scalar, vectorial or tensorial character of quantities is pointed out, especially when this is needed for thedefinitions.In most cases only one name and only one symbol for the quantity are given; where two or more names or twoor more symbols are

29、given for one quantity and no special distinction is made, they are on an equal footing.When two types of italic letters exist (for example as with and ; and ; a and ; g and ) only one of theseis given. This does not mean that the other is not equally acceptable. It is recommended that such variants

30、should not be given different meanings. A symbol within parentheses implies that it is a reserve symbol, to beused when, in a particular context, the main symbol is in use with a different meaning.In this English edition, the quantity names in French are printed in an italic font, and are preceded b

31、y fr. Thegender of the French name is indicated by (m) for masculine and (f) for feminine, immediately after the noun inthe French name.0.3 Tables of units0.3.1 GeneralThe names of units for the corresponding quantities are given together with the international symbols and thedefinitions. These unit

32、 names are language-dependent, but the symbols are international and the same in alllanguages. For further information, see the SI Brochure (8thedition 2006) from BIPM and ISO80000-1.The units are arranged in the following way:a) The coherent SI units are given first. The SI units have been adopted

33、by the General Conference onWeights and Measures (Confrence Gnrale des Poids et Mesures, CGPM). The use of coherent SI units a gis recommended; decimal multiples and submultiples formed with the SI prefixes are recommended eventhough not explicitly mentioned.DIN EN ISO 80000-5:2013-08 EN ISO 80000-5

34、:2013 (E) 4 b) Some non-SI units are then given, being those accepted by the International Committee for Weights andMeasures (Comit International des Poids et Mesures, CIPM), or by the International Organization of LegalMetrology (Organisation Internationale de Mtrologie Lgale, OIML), or by ISO and

35、IEC, for use with the SI.Such units are separated from the SI units in the item by use of a broken line between the SI units and theother units.c) Non-SI units currently accepted by the CIPM for use with the SI are given in small print (smaller than the textsize) in the “Conversion factors and remar

36、ks” column.d) Non-SI units that are not recommended are given only in annexes in some parts of this InternationalStandard. These annexes are informative, in the first place for the conversion factors, and are not integralparts of the standard. These deprecated units are arranged in two groups:1) uni

37、ts in the CGS system with special names;2) units based on the foot, pound, second, and some other related units.e) Other non-SI units given for information, especially regarding the conversion factors, are given in anotherinformative annex.0.3.2 Remark on units for quantities of dimension one, or di

38、mensionless quantitiesThe coherent unit for any quantity of dimension one, also called a dimensionless quantity, is the number one,symbol1. When the value of such a quantity is expressed, the unit symbol1 is generally not written outexplicitly.EXAMPLE1 Refractive index Prefixes shall not be used to

39、form multiples or submultiples of this unit. Instead of prefixes, powers of 10 arerecommended.EXAMPLE2 Reynolds number Considering that plane angle is generally expressed as the ratio of two lengths and solid angle as the ratio oftwo areas, in 1995 the CGPM specified that, in the SI, the radian, sym

40、bol rad, and steradian, symbol sr, aredimensionless derived units. This implies that the quantities plane angle and solid angle are considered asderived quantities of dimension one. The units radian and steradian are thus equal to one; they may either beomitted, or they may be used in expressions fo

41、r derived units to facilitate distinction between quantities ofdifferent kinds but having the same dimension.0.4 Numerical statements in this International StandardThe sign is used to denote “is exactly equal to”, the sign is used to denote “is approximately equal to”, andthe sign is used to denote

42、“is by definition equal to”.Numerical values of physical quantities that have been experimentally determined always have an associatedmeasurement uncertainty. This uncertainty should always be specified. In this International Standard, themagnitude of the uncertainty is represented as in the followi

43、ng example.EXAMPLEIn this example, , the numerical value of the uncertainty indicated in parentheses is assumed toapply to the last (and least significant) digits of the numerical value of the length . This notation is used whenrepresents the standard uncertainty (estimated standard deviation) in th

44、e last digits of . The numericalexample given above may be interpreted to mean that the best estimate of the numerical value of the length (when is expressed in the unit metre) is , and that the unknown value of is believed to lie betweenand with a pr obability determined by the standarduncertainty
