图形符号. 试验方法. 第3部分: 符号指涉相关的试验方法

[中文适用范围]： ISO 9186 的这一部分指定了一种测试图形符号的指示物关联的方法，该方法旨在向熟悉该符号旨在表示或代表的内容（指示物）的用户传达信息。 所指对象可以是专门化的，因此不能指望公众在没有熟悉培训的情况下熟悉它们。 目的是开发图形符号，当没有提供补充（即解释性）文本时，熟悉所指对象的用户可以正确识别这些图形符号。 当无法获得这样的图形符号时，可能需要呈现图形符号以及用目标用户的语言解释其含义的补充文本。 注 1：或者，可能有必要通过将图形符号的含义包含在手册、说明或培训中来告知人们图形符号的含义。 注 2：ISO 9186-1 规定了测试图形符号可理解性的方法。 ISO 9186-2 指定了一种测试图形符号感知质量的方法，即图形符号元素可以被正确识别的程度。 [外文原描述]： ISO 9186-3:2014 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, 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 symbol 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 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 identified.
