The work of preparing International Standards is
16、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 non-governmental, in liaison with ISO, also take part
17、in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular
18、 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 Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this do
19、cument may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.
20、org/patents).Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO

22、be consistent with ISO/TS 23768-1. ISO 2015 All rights reserved vBS ISO 21107:2015ISO 21107:2015(E)IntroductionElectronic media are used more and more when purchasing and selling products. This also applies to the rolling bearing industry, where it can be expected that a large proportion of sales wi
23、ll be processed via electronic media.One potential problem when ordering bearings is that designations, especially designations for special executions and variants, differ from one bearing supplier to another. For the electronic media business there is, therefore, a need for customers and distributo
24、rs to have available a system that makes it possible to identify a bearing quickly and easily when the bearing designation is not known.This can be achieved using a computerized search structure. The user responds to specified simple questions on a computer screen about visual bearing components (di
25、mensions, number of rolling element rows, cage, etc.) and, if needed, about performance criteria and other characteristics. Based on these input values, the computer provides possible bearing designations and other information.In order to facilitate programming and provide the user with the same and
26、 consistent input vocabulary, independent of supplier, this International Standard provides a standardized search structure for electronic media with a vocabulary for identifying bearings, bearing components and accessories based on ISO 5593 and other ISO/TC 4 International Standards.When creating t
27、heir own search structures, some bearing manufacturers and/or distributors may decide they have a need to customize certain properties or value domains in order to refine the selection of the possible bearing designation(s) that will meet the purchasers requirements. If this is done, then, where pos
28、sible, it is recommended that the terminology of ISO 5593 and other appropriate ISO documents for rolling bearings be used.SI units are used in ISO International Standards, but it is recognized that the properties in this document can also be used for inch dimension products.vi ISO 2015 All rights r

37、 product easily and correctly, even when a product specification is not complete or is missing. This International Standard is built up to meet this requirement and makes it possible to identify dimensions, characteristics and demands on performance of rolling bearings, bearing housings and accessor
38、ies with a standardized vocabulary.Using the Internet, for instance, a purchaser can go to the “Home page” of a bearing manufacturer or a distributor and select a search program (individually established by each bearing manufacturer or distributor, but based on this International Standard). Then, by
39、 answering given questions (with specified alternative options), obtain a list of one or more product options with designations, availability, prices, etc.The advantage of using a standardized search structure is that the purchaser always works with the same vocabulary, independent of manufacturer,
40、and the risk of misunderstanding and confusion is reduced. As most properties of interest are included in the search structure, this makes programming considerably easier.4.2 Layout of the search structureThe layout of the search criteria follows the general structure as used in the Internet environ
41、ment, i.e. an XML (extensible mark-up language) specification for defining the data structure.The data structure is built up in the way shown below and illustrated in Figure 1 and Table 1.There are three levels of classification non-leaf characterization class, leaf characterization class and proper
42、ty as defined in Clause 3.Properties and Value domains to each class cover the information needed to define a product and are specified in 5.2 to 5.9 and 6.2. These properties and value domains are based on typical product ranges which can be found in manufacturers catalogues and brochures.Each user
43、 of this International Standard can select the applicable properties and value domains from this International Standard, and add further properties and value domains if needed. Additional value domains, either individually or as a group, can also be included under the value domain “Other”. In genera
44、l, the value domain “Other” is not shown in the tables, except for the properties “Tolerance” and “Clearance” with the only value domain “Normal”.It is possible to identify a product on the basis of class, properties and value domains.For the user this is, however, not a problem when selection is ma
45、de from the value domains presented in a search program. The supplier determines the product range value domains, and the programmer has to consider the logic in the value domains presented, so that combinations that are not possible are excluded during the selection process.An example of how to use
