Log In Sign Up. For a long time, differences have exist- ed in the flags used on beaches around the world, a dangerous problem identified by the World Tourism Organization. Rationale behind the design The final group of symbols is actually the largest, and involves those for use on equipment covering a wide range of uses, including, for example, industrial machinery, motor vehicles and household electrical products.

Methods for testing comprehensibility. Views Read Edit View history.

9168-2 test resulted in the recommendation of pictorial symbols for 20 of the referents. Thinking of a new symbol? In fact, we come across graphical symbols in just about every human activity. Company organization, management and quality. Also the feedback from evaluation can provide the designers valuable input to re-design the graphical symbols, so at its best the test methods are used in 1986-2 co-operation with designers to allow iterative development of graphical symbols — and improved comprehensibility.

The test indicated that more symbolic pictograms like “City Center” or “Obstacles on the Road” are less likely to be comprehended, than sign containing elemental objects like “Ferry Boat”, or “Deer on Road”.

However, there are some messages which are incapable of direct representation and require an abstract image, an example being the biological 9186–2 warning sign. There is a range of conventions for representing different functions and actions, such as movement and force.


There are many reasons for this, including the fact 916-2 the user groups are more frequently part of a trained workforce, and that the graphical symbols have to be reproduced in a much smaller size.

This is being followed with new work starting on ISOPublic information guidance systems – Design principles and requirements for elements – Part 1: ISOGraphical symbols – Safety colours and safety signs – Safety signs used in workplaces and public areasis the core standard containing safety signs.

Mechanical systems and components for general use Over potential symbols have already been identified for future consideration in such areas as sports, tourism, commerce and transport.

If no variants exceed any of the thresholds, new variants should be collected. Sciences humaines et sociales, lettres. Its coordination role helps ensure good design and avoid unnecessary proliferation and duplication.

Alert me in case of modifications on this product contact us. Method for testing perceptual quality. The whole basis of the work implies close cooperation with other technical committees and industry bodies.

The method for selecting the most comprehensible variants out of big range of graphical symbols.

In a second step the answers are classified by 3 independently working judges into several categories, ranging from “Correct understanding of the symbol is certain” to “No response is given”.

ISO and ISO use the same graphical images for people and objects, and are based on the premise that a symbol should be readily associated with its intended meaning. Symbols can already be easily seen on their own or as part of signs in 916-2 kinds of places – in the home or office; in the car or on the beach; in a factory or airport.


Variants of graphical symbols are presented to the respondents in random order. This revised standard was published earlier this year and will soon be joined by its companion, ISOwhich covers methods for testing perceptual quality. Furthermore, the subcommittee Web sites include the application forms and templates for designers.

The committee has very active working groups supported by experts from all over the world. The respondents’ task is to judge the comprehensibility of 9186- variant, giving the percentage of people in their country, who they would expect to interpret the symbol correctly.

It covers the main requirements for images displayed in airports and other public areas, but it was also produced with the expectation that the graphical symbols would be used on maps and guides. The procedures describe two testing methods, the comprehensibility judgement test and the comprehension test.

Small changes in design may cause clear differences is the understanding which the designers might not have anticipated and there are also cultural differences. Graphical symbols intended to be displayed on variable message signs have been evaluated applying the ISO standard. Symbols cannot solve all problems!

Retrieved from ” https: The workload is handled through its three subcommittees SC: Mining and minerals The respondents have to write down what they think a symbol means.

Health care technology Safety at the beach In recent years, subcommittee SC 2 has been working closely with industry partners, such as lifesaving organizations, in the water safety area. Guidance for the use of water safety signs and beach safety flags will be published soon giving helpful guidance for their use. JavaScript seems to be disabled in your browser.
