Continued grow

18、th of international trade requires graphical symbols to be understood. This part of ISO 9186 specifies a method for assessing the referent association of graphical symbols by familiarizing people with a set of specialized referents and then testing what proportion of those people can associate a par

19、ticular graphical symbol with its referent. ISO 9186-1 specifies a method of testing what proportion of people can comprehend a graphical symbol correctly. ISO 9186-2 specifies a method of testing how well people can identify the elements which make up a graphical symbol. This part of ISO 9186 speci

20、fies a method of familiarizing people with a set of specialized referents and then testing what proportion of those people can associate a graphical symbol with its referent ISO 2014 All rights reserved vBS ISO 9186-3:2014BS ISO 9186-3:2014Graphical symbols Test methods Part 3: Method for testing sy

21、mbol referent association 1 Scope This part of ISO 9186 specifies a method for testing the referent association of graphical symbols intended to communicate information to users who are familiar with what the symbol is intended to denote or represent (the referent). The referents can be specialized,

22、 so that the general public cannot be expected to be familiar with them without familiarity training. The intention is to develop graphical symbols which are correctly recognized by users familiar with the referents when no supplementary (i.e. explanatory) text is presented. When such a graphical sy

23、mbol cannot be obtained, it might be necessary to present a graphical symbol together with supplementary text explaining its meaning in the language of the intended users. NOTE 1 Alternatively, it could be necessary to inform people about the meaning of the graphical symbol by including its meaning

24、in manuals, instructions, or training. NOTE 2 ISO 9186-1 specifies a method for testing the comprehensibility of graphical symbols. ISO 9186-2 specifies a method for testing the perceptual quality of graphical symbols, the extent to which the elements of the graphical symbol can be correctly identif

25、ied. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any

30、a symbol can be recognized when the symbol alone is presented 3.5 referent facility, control, display, concept, or object that a graphical symbol is intended to represent 3.6 variant alternative graphical symbol design for a given referent 4 Principle Symbols for specialized referents are used to de

31、note or represent facilities, controls, displays, concepts, or objects. Many different referents/graphical symbols can be within the working environment and on equipment operated by specialist users. The method for testing comprehensibility described in ISO 9186-1, which involves presenting particip

32、ants with a symbol and asking them to say what they think it means, is not appropriate for testing a symbol for a specialized referent which is not familiar to the participants. This is because they might respond “dont know” because they are ignorant of the referent, not because the symbol does not

33、provide a clear representation of its referent. It is, therefore, necessary to use a different method for testing symbols for specialized referents, a method which includes an initial stage in which respondents are familiarized with the referents and demonstrate familiarity before the symbols are te

34、sted. This is referred to as familiarity training. When the respondent is familiar with specialized referents, symbols can be tested by presenting them to the respondents together with a list of the familiarized referents and asking them which, if any, of the referents is indicated by the symbol. Th

35、is is called the symbol referent association test. In order to avoid later responses being unduly influenced by earlier ones, and to reduce the ability to make a correct response by a process of elimination, the test should include some items in which none of the familiarized referents presented is

36、the one intended to be represented by the symbol. Every test question should include the possible answer “none of these”. The size of the set of symbols to be tested depends on the context in which the symbols are used. For example, the set might be all the symbols found on a particular item of equi

37、pment or on a number of items of equipment in a particular location. In a set, there are typically many symbols to be tested.2 ISO 2014 All rights reservedBS ISO 9186-3:2014ISO 9186-3:2014(E) 5 Pre-test information Before embarking on testing, the submitter shall obtain a copy of whatever forms are

38、required by the standards organization for submitting the graphical symbol for standardization and shall ensure that they are in a position to provide whatever information is required on those forms. NOTE 1 Application forms for submission of public information symbols for standardization by ISO/TC

39、145 are available on www.iso.org/tc145/SC1orfromtheISO/TC145/SC1 secretary. Application forms for submission of safety symbols for standardization by ISO/TC 145 are available on www.iso.org/tc145/SC2orfromtheISO/TC145/ SC2 secretary. Application forms for submission of symbols on equipment for stand

40、ardization by ISO/TC 145 are available on www.iso.org/tc145/SC3orfromtheISO/TC145/SC3 secretary. NOTE 2 If necessary, the secretary of the relevant standards committee can provide supporting information such as whether testing can be required in a number of countries, whether there are any requireme

41、nts regarding the format in which symbols are to be submitted. The submitter shall ensure that the symbol variant or variants to be tested have been designed in accordance with the relevant design principles and design criteria. NOTE 3 Design principles and design criteria for graphical symbols are

42、specified in ISO 3864, ISO 22727, and IEC/ISO 80416. NOTE 4 A standards organization can require a minimum number of symbols or variants to be tested. Where the test is to be conducted in a number of countries, the submitter shall ensure that all materials, including computer presentations when they

43、 are used, are of the same standard. With both paper and computer presentation, it is essential that all presentations are of an equivalent legibility and that all images are of an equivalent quality. 6 Familiarity training A person familiar with the referents relevant to the set of symbols under co

44、nsideration should construct a list of all referents, each entry in the list being paired with a simple description of what the referent means (its function) if the referent meaning is not commonly known. NOTE An example of a list of referents and their functions is provided in Table A.1. Potential

45、respondents on the referent association test of the symbols should be presented with the list of referents and their functions and asked to read through the list or study it until they feel they are familiar with all the entries. When they consider themselves familiar with the list contents, they sh

46、ould be tested on their familiarity by presenting to them a list of the referents in a random order and asking them to state what the referent means. The person marking the test should decide for each response whether it shows correct understanding of the referents function. The respondent should be

47、 accepted as a member of the symbol referent association test respondent group if they show understanding of all the referents in the list. A respondent can go through the familiarity procedure and take the familiarity test again until understanding of all the referents is achieved. At least 25 resp

48、ondents who have demonstrated understanding of the referents are required for the symbol referent association test. 7 Symbol referent association test 7.1 General Carry out the test using either a printed presentation or computer screen presentation, depending on which is the most practicable. Compu

49、ter screen presentations include internet presentations. NOTE For the description of the test using a computer screen presentation, the word “page” is used for a predefined presentation of text and/or graphic elements and their layout on a computer screen. For screen presentations, use a screen size such that the test pages are clearly legible to the respondents. Each test page content shall fit legibly on the screen in its entirety or with only vertical scrolling required. ISO 2014 All rights reserved 3BS ISO 9186-3:
