10、e Einheitensystem (SI) Notes to the German version of this standard and on deviations from usage in German-speaking areas Users of this standard should note that the 2006 CODATA values cited here are no longer current and have been replaced by the 2010 values. This German version of the standard cit
11、es the 2010 values. Re 3.1 This definition of “quantity” is deemed to be too broad (see also NOTE 2 to this definition). In the German-speaking area, the corresponding term “Gre” is restricted to ratio-scaled characteristics and differences between interval-scaled characteristics. Thus, in German on
12、e does not speak of “Ordinalgren” (ordinal quantities) and “Nominalgren” (lit. nominal quantities, referred to in the ISO Standard as “nominal properties”) but rather “Ordinalmerkmale” (ordinal characteristics) and “Nominalmerkmale” (nominal characteristics), see also DIN 1313, DIN 55350-12 and DIN
13、ISO 3534-2. According to DIN 1313:1998-12, 3.1 and 11.2, the definition of “Gre” (quantity) is: “Characteristic, such that for any two values of the characteristic a ratio is defined which is a real number.” Re 3.4, NOTE 3 Although the “number of entities” (“Anzahl”) does indeed belong in any system
14、 of quantities, it is not a base quantity as defined in 3.4, also not by agreement. An example of this term is the number of revolutions of a circular wheel defined as the length of the distance covered by a point on the edge of the wheel divided by its circumference, which is a derived quantity wit
15、h the corresponding coherent derived unit expressed in the base unit of one, see BIPM brochure “International System of Units”, 2.2.1, Table 2. See also NOTE 3 to 3.10. This has been correctly translated in this German version. Re 3.8 The German expression “Gre der Dimension Zahl” (literally, “quant
16、ity of dimension number”) reflects the fact that the values of these quantities are (real) numbers. The German expressions “Gre der Dimension Eins” (quantity of dimension one) and “dimensionslose Gre” (dimensionless quantity) are obsolete and should no longer be used. Re 3.9 In the definition the co
17、rrect term “Grenwert(e)” (“value(s) of quantity/ies”) should be used instead of “Gre(n)” (“quantity/ies”). This has been correctly translated in this German version. Re 3.10, NOTE 3 Although the number one, symbol 1, does indeed belong in any coherent system of units, it is not a base unit as define
18、d in 3.10, also not by agreement. This is because examples for the quantity “number” (“Zahl”) are often derived quantities with the coherent derived SI unit of one, see BIPM brochure “International System of Units”, 2.2.1, Table 2. See also NOTE 3 to 3.4. This has been correctly translated in this G
19、erman version. See also 6.5.5. Re 3.16 A German translation of the BIPM brochure “International System of Units” is available for free from the German national metrology institute Physikalisch-Technische Bundesanstalt (PTB) at http:/www.ptb.de/cms/fileadmin/internet/publikationen/DasInternationaleEi
20、nheitensystem.pdf Re 3.16, NOTE 4 Although the quantity “number (of items)” (“Anzahl”) does indeed belong in any system of quantities, it is not a base quantity as defined in 3.4, also not by agreement. The coherent derived SI unit is one, see BIPM brochure “International System of Units”, 2.2.1, Ta
21、ble 2. See also NOTE 3 to 3.4. This has been correctly translated in this German version. Re 3.26 The definition of “quantity” (“Gre”) here is deemed to be too broad (see also NOTE 2 to 3.1). In the German-speaking area, the corresponding term “Gre” is restricted to ratio-scaled characteristics and
22、differences between interval-scaled characteristics. Thus, in German one does not speak of “Ordinalgren” (ordinal quantities) and “Nominalgren” (lit. nominal quantities, referred to in the ISO Standard as “nominal properties”) but rather “Ordinalmerkmale” (ordinal characteristics) and “Nominalmerkma
23、le” (nominal characteristics), see also DIN 1313, DIN 55350-12 and DIN ISO 3534-2. In this German version, the term “ordinal quantity” has been consistently translated as “Ordinalmerkmal”. Re 3.27 The definition of “quantity” (“Gre”) here is deemed to be too broad (see also NOTE 2 to 3.1). In the Ge
24、rman-speaking area, the corresponding term “Gre” is restricted to ratio-scaled characteristics and differences between interval-scaled characteristics. Thus, in German one does not speak of “Ordinalgren” (ordinal quantities) and “Nominalgren” (lit. nominal quantities, referred to in the ISO Standard
25、 as “nominal DIN EN ISO 80000-1:2013-08 4 properties”) but rather “Ordinalmerkmale” (ordinal characteristics) and “Nominalmerkmale” (nominal characteristics), see also DIN 1313, DIN 55350-12 and DIN ISO 3534-2. However, none of the examples in 3.27 are an example for a true quantity-value scale. For
26、 this reason a correct German translation of the term and definition would be as follows: “geordnete Skala” bzw. “geordnete Menge von Werten von Merkmalen einer Art, die zur Ordnung von Merkmalen dieser Art nach zunehmendem oder abnehmendem Wert verwendet wird”. In this German version the term “quan
27、tity-value scale” has been translated as “geordnete Skala” wherever appropriate. Re 4.3 The first sentence of the third paragraph “It is a matter of choice how many and which quantities are considered to be base quantities” is a direct contradiction to the condition in the definition in 3.4 that “no
28、 quantity in the subset can be expressed in terms of the other quantities within that subset”. Re 6.1 The English expression here “example of a quantity” is an attempt to avoid using the expression “value of a quantity”. This has been correctly translated as “Grenwert” in this German version. See al
29、so the above remark regarding 3.9. Re 6.5.3 The two last sentences are yet another failed attempt to make the coherent derived unit one a base unit. Re Clause 7 According to DIN 1338 formulae and symbols are preferably to be printed using a serif font because such fonts are less potentially confusin
30、g, e.g. in terms of the differences between a small l , a capital I and 1. This also applies to symbols for quantities (italics/sloping) and symbols for units (roman/upright). Thus the current rule for DIN and ISO Standards that all upright symbols be set in Arial makes it impossible to distinguish
31、between the symbol for an imaginary part (Im) and that for the lumen (lm), for which reason this rule should be abolished. Re 7.1.3 Writing a product in the form without any spaces ( ba ) is against the rule set down in DIN 1338, according to which the factors of a product are to have at least one s
32、pace (of a defined length) between them. According to DIN 1338 and German school curricula, the multiplication sign (cross) is only to be used to indicate vector products and formats (such as paper sizes), but not for the multiplication of scalar quantities such as numbers. In Germany, the dot as a
33、multiplication sign is to be used for indicating the multiplication of scalar quantities. See also NOTE 1 to 7.1.3. In this German version, the dot is used throughout as a multiplication sign for scalar quantities, except in 7.1.3 and 7.3.3. According to DIN 1302:1999-12, Annex A, Re 4.11: In German
34、y, in mathematics lessons in schools, for the general public, and when indicating proportions and ratios, the colon “:” is also to indicate division. The colon is also used in division when giving the remainder in the form rqnm Rest: Re 7.1.3, penultimate paragraph with EXAMPLE 4 and 7.1.4, EXAMPLE
35、2 The requirement that quantities are not to be written out as words or abbreviations in equations, as in VolumenMasseDichte , is completely unacceptable because such a form is urgently needed for general explanations, particularly in schools and training centres. Therefore, in DIN 5477:1983-02, 1.1
36、, examples and in the example to 1.2 four equations give the quantities as words, e.g. %1313,0esNettopreis des BetrageuerMehrwertst der BetrageuersatzMehrwertst Re 7.2.2 NOTE This note says that a compound unit formed by multiplication may be written without a space; this is a direct contradiction t
37、o DIN 1301-1 and DIN 1338, according to which the factors of a product may not be written without a space, as in ab . Re 7.2.4 In German the name of the product of two units is formed by joining the two words to form one word, either without a space or with a hyphen, see also DIN 1301-1. DIN EN ISO
38、80000-1:2013-08 5 In individual cases, the power of two can be expressed by the prefix “Quadrat-” (e.g. “Quadratmeter” for “Meter zum Quadrat”, or square metre). There is no German equivalent for the English term “cubed”. In German the term “Kubikmeter” is often used for “Meter hoch drei” (cubic met
39、re). Re 7.2.5 In German the names of all quantities and units are capitalized because they are nouns (e.g. “Lnge”, “Meter”, “Kraft”, “Newton”). Re 7.3.2 In the German-speaking area the comma is used as a decimal sign, also in accordance with the ISO/IEC Directives. Re 7.3.3 According to DIN 1338 and
40、 German school curricula, the multiplication sign (cross) is only to be used to indicate vector products and formats (such as paper sizes), but not for the multiplication of scalar quantities such as numbers. In Germany, the dot as a multiplication sign is to be used for indicating the multiplicatio
41、n of scalar quantities. See also NOTE 1 to 7.1.3. In this German version, the dot is used throughout as a multiplication sign for scalar quantities, except in 7.1.3 and 7.3.3. Re 7.3.4 The term “rounding range” has been translated with the German equivalent of the internationally used term “place va
42、lue”, i.e. “Rundestellenwert”, see DIN 1333:1992-02, 10.1.5 NOTE. Re A.3.3, Example 3 The German equivalent of the English term “refractive index” used here is “Brechzahl” and not “Brechungsindex” (as has been erroneously translated here). Re Annex B The term “rounding range” has been translated wit
43、h the German equivalent of the internationally used term “place value”, i.e. “Rundestellenwert”, see DIN 1333:1992-02, 10.1.5 NOTE. Re B.3 In the German-speaking area, Rule B is given priority (it is also known as “kaufmnnisches Runden”). However, the use of Rule A is not recommended, see DIN 1333:1
44、992-02, 4.5.1 and Notes. Re C.2 The statement “when it acts on a linear system” is unnecessary and confusing. The English text “For sinusoidal time-varying root-power quantities, the root-mean square value is the argument of the logarithm” is not only incorrectly worded (the argument of the logarith
45、m is a ratio), but also only true in exceptional cases.
