18、worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented

19、 on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop thi

In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Di

24、ISO/TC 213, Dimensional and geometrical product specifications and verification.This third edition cancels and replaces the second edition (ISO 1:2002), which has been technically revised. Specifically, the following points have changed: the standard reference temperature definition has been include

25、d; consequently, the title, introduction and scope, have been changed; the general definition of reference temperature has been included.iv ISO 2016 All rights reservedBS EN ISO 1:2016ISO 1:2016(E)IntroductionThis International Standard is a geometrical product specification (GPS) standard and is to

26、 be regarded as a fundamental GPS Standard (see ISO 14638:20151). For more detailed information on the relationship of this International Standard to other standards and the GPS matrix model, see Annex B.The definitions of the units, including those of length and temperature, are adopted by the Gene

27、ral Conference of Weights and Measures (CGPM) under the authority of the Convention of the Metre. These definitions are maintained in the SI brochure.5The unit of length, the metre, is independent of temperature. The current definition of the metre6is based on the distance light travels in vacuum du

28、ring a unit of time. However, a physical object is subject to thermal expansion and consequently, its geometrical and dimensional properties are dependent on its temperature. Specifying a reference temperature allows the geometrical and dimensional properties of a physical object to be unambiguously

29、 stated. ISO 2016 All rights reserved vBS EN ISO 1:2016BS EN ISO 1:2016Geometrical product specifications (GPS) Standard reference temperature for the specification of geometrical and dimensional properties1 ScopeThis International Standard defines the concepts of a reference temperature and of the

30、standard reference temperature, and specifies the standard reference temperature value for the specification of geometrical and dimensional properties of an object. Some examples of geometrical and dimensional properties include size, location, orientation (including angle), form and surface texture

31、 of a workpiece.This International Standard is also applicable to the definition of the measurand used in verification or calibration.2 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.2.1reference temperaturetemperature of an object, having a uniform

32、 temperature, specified as part of the definition of a geometrical or dimensional propertyNote 1 to entry: The specification of a geometrical or dimensional property is typically given in technical product documentation, e.g., on an engineering drawing or in a CAD file, or in the specification of th

33、e measurand (the quantity intended to be measured).2.2standard reference temperatureinternationally agreed-upon reference temperatureNote 1 to entry: In prior editions of this International Standard, the term “standard reference temperature” was defined as its assigned numerical value, i.e. 20 C. In

34、 this edition, the definition of the reference temperature (2.1) and the assignment of a standardized value to this temperature are separately addressed (Clause 3).3 Standard reference temperature value for the specification of geometrical and dimensional propertiesThe standard reference temperature

35、 value for the specification of geometrical and dimensional properties shall be fixed at 20 C. Unless otherwise explicitly specified, the reference temperature for geometrical and dimensional properties of workpieces shall be the standard reference temperature. See Annex A for information on the use

36、 of the reference temperature specification.NOTE 1 There is only one standard reference temperature value and it is fixed at 20 C. However, this does not prevent a different (non-standard) reference temperature from being specified for all geometrical and dimensional properties of a workpiece or for

37、 a specific geometrical or dimensional property on a workpiece, provided it is explicitly stated as part of the specification.NOTE 2 The specification of a non-standard reference temperature may increase the measurement uncertainty during verification because most dimensional measuring equipment and

38、 gauges are calibrated with their measurand defined at the standard reference temperature.INTERNATIONAL STANDARD ISO 1:2016(E) ISO 2016 All rights reserved 1BS EN ISO 1:2016ISO 1:2016(E)Annex A (informative) Use of the reference temperature specificationSpecifying geometrical and dimensional propert

39、ies at a single temperature value can raise questions sincea) the functional requirements of any physical workpiece include other temperatures,b) verification cannot physically occur at an exact, uniform temperature.Regarding the issue that workpiece functional requirements include other temperature

40、s, it is important to note that a designer typically specifies not only the requirements on the geometric and dimensional properties of the workpiece (usually at the standard reference temperature value), but also separate requirements on the material properties of the workpiece. Combining the knowl

41、edge of how a specified material behaves at different temperatures and the specified geometric and dimensional properties at a single temperature can allow a designer to ensure a workpiece will meet geometric and dimensional functional requirements over a range of temperatures.Regarding the issue th

42、at any geometrical or dimensional verification inevitably occurs at a temperature different than the reference temperature, an adequate correction for that difference is necessary (see for example ISO/IEC Guide 99:2007, 2.3, Note 32). In some cases, the correction might be zero (i.e. no correction i

43、s performed); however, in all cases, it is necessary that the lack of knowledge of the exact correction be accounted for appropriately in the measurement uncertainty see for example ISO/IEC GUIDE 98-3:2008, 3.3.2 b)3.Most measuring systems are designed to produce measurement results specified at the

44、 standard reference temperature value of 20 C even though they may be operating at a different temperature. In this case, deviations from the standard reference temperature for either the measuring system or the workpiece under measurement lead to additional measurement uncertainty contributors; see

45、 ISO/TR 160154for additional information. The term reference temperature should not be confused with the term rated operating condition.2 ISO 2016 All rights reservedBS EN ISO 1:2016ISO 1:2016(E)Annex B (informative) Relation to the GPS matrix modelB.1 GeneralThe ISO GPS matrix model given in ISO 14
