19、SO 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 on that committee. International organizations, gov
20、ernmental 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. International Standards are drafted in accordance with the rules given in the ISO/IEC
21、 Directives, 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 membe
22、r bodies casting 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 14253-3 was prepared by Technical Committee ISO/TC 213, Dimensional and
23、geometrical product specifications and verification. This first edition of ISO 14253-3 cancels and replaces ISO/TS 14253-3:2002, which has been technically revised. ISO 14253 consists of the following parts, under the general title Geometrical product specifications (GPS) Inspection by measurement o
24、f workpieces and measuring equipment: Part 1: Decision rules for proving conformance or non-conformance with specifications Part 2: Guidance for the estimation of uncertainty in GPS measurement, in calibration of measuring equipment and in product verification Part 3: Guidelines for achieving agreem
25、ents on measurement uncertainty statements Part 4: Background on functional limits and specification limits in decision rules Technical Specification BS EN ISO 14253-3:2011ISO 14253-3:2011(E) ISO 2011 All rights reserved vIntroduction This part of ISO 14253 is a geometrical product specification (GP
26、S) International Standard and is to be regarded as a global GPS Standard (see ISO/TR 14638). It influences links 4, 5 and 6 of all chains of standards in the general GPS matrix. The ISO/GPS Masterplan given in ISO/TR 14638 gives an overview of the ISO/GPS system of which this part of ISO 14253 is a
27、part. The fundamental rules of ISO/GPS given in ISO 8015 apply to this part of ISO 14253 and the default decision rules given in ISO 14253-1 apply to specifications made in accordance with this part of ISO 14253, unless otherwise indicated. For more detailed information on the relation of this Inter
28、national Standard to other standards and the GPS matrix model, see Annex A. ISO 14253-1 provides decision rules for proving conformance or non-conformance with specifications of workpieces and measuring equipment when taking into account the uncertainty of measurement. ISO 14253-2 provides instructi
29、ons for preparing uncertainty budgets for determining measurement uncertainty as defined in the Guide to the Expression of Uncertainty in Measurement (GUM). However, the possibility still exists that disagreement between customer and supplier can occur on the estimated measurement uncertainty. It is
30、 becoming increasingly common for suppliers to have in place a quality system providing satisfactory assurance to the customer that the latter is receiving a product which conforms to specifications. This avoids the need for costly duplicate inspections. For this reason, the most common case of disa
31、greement over a measurement uncertainty statement or an uncertainty budget involves the customer questioning the suppliers uncertainty budget. The customer may also question the measured value of a characteristic of a workpiece or of measuring equipment, thus indirectly questioning the total uncerta
32、inty budget (see ISO 14253-1). In a rarer case of disagreement, the supplier may question the customers uncertainty budget when the customer rejects a workpiece or measuring equipment (see ISO 14253-1:1998, 6.2). In addition to those mentioned, there are other cases of disagreement, as well as other
33、 motivations that may lead to discussion of stated uncertainties.

41、e 99 apply. 4 Reaching an agreement on a stated expanded uncertainty 4.1 Early agreement on the stated measurement uncertainty In a case where either the customers or suppliers measurement uncertainty statement is in question, an uncertainty budget supporting and documenting the measurement uncertai
42、nty statement may be necessary. It is the responsibility of the party preparing the uncertainty budget to justify the individual components and the resulting estimated expanded uncertainty of the uncertainty budget. In an ideal situation, customer and supplier will address the issue of measurement u
43、ncertainty at the same time as they address the product specifications of the workpiece, at the pre-contract stage. Agreement on the magnitude of the measurement uncertainty or uncertainties and the rules for its application at this early stage of the business relationship will avoid later disputes
44、over acceptance or rejection of product and the consequent need to apply the default rules given in ISO 14253-1. NOTE In most cases, there are several GPS characteristics specified for a workpiece and for each of these characteristics a measuring task with corresponding measurement uncertainty state
45、ment is required. Two different persons can produce two different uncertainty statements due to differing knowledge, experience and assumptions. Resolving these differences at the pre-contract stage is likely to be less contentious and less costly than waiting until an argument develops over the acc
46、eptance or rejection of the product during the manufacture and delivery stage. 4.2 Possibilities for solving disagreements over a stated measurement uncertainty The most basic way of reaching an agreement is to agree to choose one of the two statements of measurement uncertainty from either party to
47、 the agreement. If this type of settlement is not appropriate, another solution is to use the more refined procedure given in Clause 5, or to use a third party consultation or a review or both. Clause 6 of ISO 14253-1:1998 gives specific rules on dealing with uncertainty of measurement when proving
48、conformance or non-conformance with a specification: supplier proving conformance with specifications (ISO 14253-1:1998, 6.2); customer proving non-conformance with specifications (ISO 14253-1:1998, 6.3). The magnitude of the measurement uncertainty is of importance, because it decreases the conform
49、ance zone (supplier proving conformance) and the non-conformance zone (customer proving non-conformance). NOTE 1 Decreasing the non-conformance zone increases the interval where non-conformance cannot be proven. According to ISO 14253-1, the measurement uncertainty is stated by the party providing the proof of conformance or non-conformance with a specification, i.e. the party making the measurements. In the following clauses of this part of ISO 14253, the party stating the measurement uncertainty is
