22、ies). 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 on that committee. International organizations, governmental and
23、 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives,
24、Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies cast
25、ing a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 8015 was prepared by Technical Committee ISO/TC 213, Dimensional and geometrical prod

BS EN ISO 8015:2011ISO 8015:2011(E) ISO 2011 All rights reserved vIntroduction This International Standard is a geometrical product specification (GPS)
27、 standard and is to be regarded as a fundamental GPS standard (see ISO/TR 14638). It influences all other standards in the GPS matrix system, i.e. all global, general and supplementary standards, as well as any other kind of document in the GPS matrix system. For more detailed information of the rel
28、ation of this International Standard to other standards and the GPS matrix model, see Annex A. This International Standard covers a number of fundamental principles that apply to all GPS standards and technical product documentation that is based on the GPS matrix system. Until this current version
29、of this International Standard was published, these principles were implied, but not formulated explicitly. This International Standard also covers the indication of ISO default specification operators and particularly the indication of non-default specification operators, either by direct indicatio
30、n or by the use of company-specific or drawing-specific defaults. For the purpose of this International Standard, a concept is considered as an abstract idea, a principle is considered as a standardized truth based on concepts upon which rules are based, and a rule is considered as a standardized pr

32、les valid for the creation, interpretation and application of all other International Standards, Technical Specifications and Technical Reports concerning dimensional and geometrical product specifications (GPS) and verification. This International Standard applies to the interpretation of GPS indic

For the purposes of this International Standard, the term “drawing” is to be interpreted in the broadest possible sense, encompassing the total package of documentation specifying the workpiece. 2 Normative references The following referenced documents are indispensa

40、r the reading of specifications on drawings 4.1 General The following assumptions regarding the interpretation of tolerance limits are the basis for the overall rules of the GPS system. General and individual specifications written on the drawing shall always be respected and are linked by default t
41、o the assumptions given in 4.2 to 4.4. 4.2 Functional limits It is assumed for interpretation that the functional limits are based on an exhaustive investigation done by experiment or theory, or a combination of both, so the functional limits are known with no uncertainty. 4.3 Tolerance limits It is
42、 assumed for interpretation that the tolerance limits are identical to the functional limits. 4.4 Workpiece functional level It is assumed for interpretation that the workpiece functions 100 % within the tolerance limits and 0 % outside the tolerance limits. 5 Fundamental principles 5.1 Invocation p
43、rinciple Once a portion of the ISO GPS system is invoked in a mechanical engineering product documentation, the entire ISO GPS system is invoked, unless otherwise indicated on the documentation, e.g. by reference to a relevant document. “Unless otherwise indicated on the documentation” means e.g. th
44、at if it is indicated on the documentation that it has been prepared in accordance with a regional, national or company standard, then that standard and not the ISO GPS system shall be used to interpret those elements of the specification that are covered by that standard.

45、5:2011(E) ISO 2011 All rights reserved 3“Tolerancing ISO 8015” can optionally be indicated in or near the title block for information, but is not required to invoke the ISO GPS system. NOTE 1 The most common way to invoke the ISO GPS system is to use one or more GPS specifications in a drawing. NOTE
46、 2 The ISO GPS system is defined in the International Standards published by ISO/TC 213. See also ISO/TR 14638. NOTE 3 That “the entire ISO GPS system is invoked” means that e.g. fundamental and global GPS standards apply and consequently that e.g. the reference temperature given in ISO 1 and the de
47、cision rules given in ISO 14253-1 apply unless otherwise indicated. The purpose of the invocation principle is to provide the formal traceability for these GPS standards and rules. 5.2 Principle of GPS standard hierarchy The ISO GPS system is defined in a hierarchy of standards that includes the fol
48、lowing types of standards in the given order: fundamental GPS standards; global GPS standards; general GPS standards; complementary GPS standards. The rules given in standards at a higher level in the hierarchy apply in all cases unless rules in standards at lower levels in the hierarchy specificall
49、y give other rules. The rules given in fundamental GPS standards, e.g. this International Standard, apply in all cases, unless the rules in a specific standard at a lower level give other rules that apply within its scope. The rules given in global GPS standards, e.g. ISO 1, apply in all cases, unless the rules in a specific general or complementary GPS standard give other rules that apply within its scope. All rules given in fundamental and global GPS standards apply in addition to the rules specifically given in general GPS
