27、) and has been taken over as EN ISO 80000-10:2013. 3 EN ISO 80000-10:2013 (E) DIN EN ISO 80000-10:2013-08 Introduction 0.1 Arrangements of the tables The tables of quantities and units in this International Standard are arranged so that the quantities are presented on the left-hand pages and the uni
28、ts on the corresponding right-hand pages. All units between two full lines on the right-hand pages belong to the quantities between the corresponding full lines 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 the preceding ed
29、ition is shown in parenthesis on the left-hand page under the new number for the quantity; a dash is used to indicate that the item in question did not appear in the preceding edition. 0.2 Tables of quantities The names in English and in French of the most important quantities within the field of th
30、is International Standard are given together with their symbols and, in most cases, their definitions. These names and symbols are recommendations. The definitions are given for identification of the quantities in the International System of Quantities (ISQ), listed on the left hand pages of the tab
31、le; they are not intended to be complete. The scalar, vector or tensor character of quantities is pointed out, especially when this is needed for the definitions. In most cases only one name and only one symbol for the quantity are given; where two or more names or two or more symbols are given for
32、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 a; g and g), only one of these is given. This does not mean that the other is not equally acceptable. It is recommended that such variants not
33、be given different meanings. A symbol within parentheses implies that it is a reserve symbol, to be used 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 by fr. The
34、 gender of the French name is indicated by (m) for masculine and (f) for feminine, immediately after the noun in the French name. 0.3 Tables of units 0.3.1 General The names of units for the corresponding quantities are given together with the international symbols and the definitions. These unit na
35、mes are language-dependent, but the symbols are international and the same in all languages. For further information, see the SI Brochure (8thedition, 2006) from BIPM and ISO 80000-1. The units are arranged in the following way: a) The coherent SI units are given first. The SI units have been adopte
36、d by the General Conference on Weights and Measures (Confrence Gnrale des Poids et Mesures, CGPM). The coherent SI units and their decimal multiples and submultiples formed with the SI prefixes are recommended, although the decimal multiples and submultiples are not explicitly mentioned. 4 EN ISO 80
37、000-10:2013 (E) DIN EN ISO 80000-10:2013-08 b) Some non-SI units are then given, namely those accepted by the International Committee for Weights and Measures (Comit International des Poids et Mesures, CIPM), or by the International Organization of Legal Metrology (Organisation Internationale de Mtr
38、ologie 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 the SI units and the other units. c) Non-SI units currently accepted by the CIPM for use with the SI are given in small print (smaller than the text siz
39、e) 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 International Standard. These annexes are informative, in the first place for the conversion factors, and are not integral parts of the standard. These deprecat
40、ed 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) Other non-SI units given for information, especially regarding the conversion factors, are given in informative annexes in some parts of thi
41、s International Standard. 0.3.2 Remark on units for quantities of dimension one, or dimensionless quantities The coherent unit for any quantity of dimension one, also called a dimensionless quantity, is the number one, symbol 1. When the value of such a quantity is expressed, the unit symbol 1 is ge
42、nerally not written out explicitly. EXAMPLE 1 Refractive index n = 1,53 1 = 1,53 Prefixes shall not be used to form multiples or submultiples of this unit. Instead of prefixes, powers of 10 are recommended. EXAMPLE 2 Reynolds number Re = 1,32 103Considering that the plane angle is generally expresse
43、d as the ratio of two lengths and the solid angle as the ratio of two areas, in 1995 the CGPM specified that, in the SI, the radian, symbol rad, and steradian, symbol sr, are dimensionless derived units. This implies that the quantities plane angle and solid angle are considered as derived quantitie
44、s of dimension one. The units radian and steradian are thus equal to one; they may either be omitted, or they may be used in expressions for derived units to facilitate distinction between quantities of different kind but having the same dimension. 0.4 Numerical statements in this International Stan
45、dard The sign = is used to denote “is exactly equal to”, the sign is used to denote “is approximately equal to”, and the sign := is used to denote “is by definition equal to”. Numerical values of physical quantities that have been experimentally determined always have an associated measurement uncer
46、tainty. This uncertainty should always be specified. In this International Standard, the magnitude of the uncertainty is represented as in the following example. EXAMPLE l = 2,347 82(32) m In this example, l = a(b) m, the numerical value of the uncertainty b indicated in parentheses is assumed to ap
47、ply to the last (and least significant) digits of the numerical value a of the length l. This notation is used when b represents the standard uncertainty (estimated standard deviation) in the last digits of a. The numerical example given above may be interpreted to mean that the best estimate of the
48、 numerical value of the length l, when l is expressed in the unit metre is 2,347 82, and that the unknown value of l is believed to 5 EN ISO 80000-10:2013 (E) DIN EN ISO 80000-10:2013-08 lie between (2,347 82 0,000 32) m and (2,347 82 + 0,000 32) m with a probability determined by the standard uncertainty 0,000 32 m and the probability distribution of the values of l. 0.5 Special remarks 0.5.1 Quantities The fundamental physical constants given in ISO 80000-1
