26、0-4:2013-08 Introduction0.1 Arrangement of the tablesThe tables of quantities and units in this International Standard are arranged so that the quantities arepresented on the left-hand pages and the units on the corresponding right-hand pages.All units between two full lines on the right-hand pages
27、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 ISO 31, the number in thepreceding edition is shown in parentheses on the left-hand page under the new number for the quantity; a dashis us
28、ed 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 field of this InternationalStandard are given together with their symbols and, in most cases, their definitions. The
29、se 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 the table; they are not intended to be complete.The scalar, vectorial or tensorial character of quantities is point
30、ed 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 given for one quantity and no special distinction is made, they are on an equal footing.When two types of italic let
31、ters 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 not recommended to give suchvariants different meanings. A symbol within parentheses implies that it is a reserve symbol, to be used when,in a par
32、ticular 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 by fr. Thegender of the French name is indicated by (m) for male and (f) for female, immediately after the noun in theFrench name.
33、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 names are language-dependent, but the symbols are international and the same in alllanguages. For further information, see the SI Broch
34、ure (7thedition 1998) from BIPM and ISO 80000-11).The units are arranged in the following way.a) The coherent SI units are given first. The SI units have been adopted by the General Conference onWeights and Measures (Confrence Gnrale des Poids et Mesures, CGPM). The use of coherent SI units1) To be
35、published. a gEN ISO 80000-4:2013 (E) 4 DIN EN ISO 80000-4:2013-08 is recommended; decimal multiples and submultiples formed with the SI prefixes are recommended eventhough not explicitly mentioned.b) Some non-SI units are then given, being those accepted by the International Committee for Weights a
36、ndMeasures (Comit International des Poids et Mesures, CIPM), or by the International Organization of LegalMetrology (Organisation Internationale de Mtrologie Lgale, OIML), or by ISO and IEC, for use with the SI.Such units are separated from the SI units in the item by use of a broken line between th
37、e 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 remarks” column.d) Non-SI units that are not recommended are given only in annexes in some parts of this InternationalS
38、tandard. 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) units in the CGS system with special names;2) units based on the foot, pound, second, and some other related units.e)
39、 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 dimensionless quantitiesThe coherent unit for any quantity of dimension one, also called a dimensionless quantity, i
40、s the number one,symbol 1. When the value of such a quantity is expressed, the unit symbol 1 is generally not written outexplicitly.EXAMPLE 1 Refractive index Prefixes shall not be used to form multiples or submultiples of the unit one. Instead of prefixes, powers of 10 arerecommended.EXAMPLE 2 Reyn
41、olds 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, symbol rad, and steradian, symbol sr, aredimensionless derived units. This implies that the quantities plane a
42、ngle 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 for derived units to facilitate distinction between quantities ofdifferent kind but having the same dimension
43、.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 “is by definition equal to”.Numerical values of physical quantities that have been experimentally determined
44、 always have an associatedmeasurement uncertainty. This uncertainty should always be specified. In this International Standard, themagnitude of the uncertainty is represented as in the following example.EXAMPLEIn this example, , the numerical value of the uncertainty indicated in parentheses is assu
45、med 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 the last digits of . The numericalexample given above may be interpreted to mean that the best estimate of the
46、 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 probability determined by the standarduncertainty and the probability distribution of the values of .n = 1,53 1 = 1,53Re = 1,32 103= :=l = 2,347 82(32) ml = a(
