Foreword

GB/T 16900 is one of the national standards in the "Graphic Symbol Representation Rules" series. The structure and name of this series of national standards are as follows. a) GB/T 16900 "Graphic Symbol Representation Rules" is intended to be divided into the following 4 parts. --- Part 1. General Provisions; --- Part 2. Understanding test method; --- Part 3. Perception test method; --- Part 4. Object correlation test method. b) GB/T 16901 "Rules for Representing Technical Documents with Graphic Symbols" is divided into the following parts. --- Part 1. Basic rules. c) GB/T 16902 "Rules for expressing equipment with graphical symbols" is divided into the following 5 parts. --- Part 1. Design principles of symbol original drawings; --- Part 2. The form and use of arrows; --- Part 3. Application Guidelines; --- Part 4. Guidelines for redrawing graphical symbols as icons; --- Part 5. Design guidelines for icons. d) GB/T 16903 "Design Principles and Requirements for Graphic Information Symbols for Symbols Representing Rules of Graphic Symbols". This part is Part 2 of GB/T 16900. This section was drafted in accordance with the rules given in GB/T 1.1-2009. This part replaces GB/T 16903.2-2013 "Rules for the representation of signs with graphical symbols Part 2.

This part uses the redrafting method to modify the use of ISO 9186-1..2014 "Graphic Symbol Test Method Part 1. Understanding Test method". Compared with ISO 9186-1..2014, this part has the following structural changes. --- Change Chapter 5 from suspended paragraph to untitled first-level article; --- Change the suspended section under 6.4, 6.5, 6.6, 6.7 to the untitled second level.

Introduction

Due to the increasing use of non-verbal forms as information expression in buildings, other places and public services, multinational travel The continuous growth of travel, tourism and trade also requires that the graphical symbols used can be understood, so this part of GB/T 16900 is formulated. The purpose of preparing this part is to formulate graphic symbols that can be correctly understood by users even without supplementary text (ie explanatory text). If the developed graphic symbol cannot meet this requirement, the graphic symbol may need to be used together with the supplementary text (the supplementary text is used for potential use The author ’s language explains the meaning of the graphic symbols). This section is intended for use by all technical committees responsible for formulating special graphical symbols in the industry to ensure that there is a one-to-one correspondence between graphical symbols and meanings. Any other organization that needs to understand the understanding of graphical symbols can also be used. Graphical symbol representation rules Part 2. Understanding test method

1 Scope

3 Terms and definitions

The terms and definitions defined in GB/T 15565 apply to this document.

4 General requirements

The comprehensibility test should be used to evaluate the program's comprehensibility. In the comprehension test, the subjects were asked about the plan What is the meaning of this graphic symbol? ". If you need to further clarify the participant ’s response, or need the participant to respond in response, you can repeat The participant was asked "Do you know what to do when you see this graphic symbol?". Give each plan based on the percentage of "correct" in the answer category Scoring. Note. This part uses paper test or computer screen to display these two test methods. Computer screen display methods include Internet testing. 6.2.8 and 6.3.5 gives the Internet test implementation guide.

5 Preparations before testing

5.1 It should be ensured that the design of the tested graphic symbol scheme meets the requirements of relevant design principles and design standards. ......
