2011-11-07 2011 Copyright TCO Development AB. All rights reserved.IntroductionTCO Development has, since the end of the 1980s, influenced the development of ITequipment, particularly Visual Display Units (VDUs). Today, TCO Development’sinternational certification system – TCO Certified – makes it easy to choosesustainably designed and produced IT and office equipment. It is a third partycertification, Type 1 eco label according to ISO14024. The point of departure for thisproduct group’s criteria is the commitment to sustainability, whereby long termeconomic gains are dependent on social and environmental considerations. Thecriteria for TCO Certified include environmental and social aspects, and have beenbroadened from product focus to also include the production phase. This is a result ofincreased expectations around the world to respect human rights in the productionand development of the products. The social responsibility criteria also cover qualityaspects of the product, such as ergonomics, emissions and electrical safety. Thecriteria related to the environment include, for both product and production, aspects,such as energy consumption, content of hazardous materials, preparation forrecycling and environmental management system at production sites.With every major update of the criteria the aim is to extend and tighten thecertification in order to keep in pace with technology innovation and development.All updates are a result of cooperation between key stakeholders, such as purchasers,users, producers, and researchers. This criteria document TCO Certified AIOcomputers 2.0, is the second version of TCO Development’s certification ofintegrated computers. Going forward, subsequent versions, 2.1, 2.2 etc., might bereleased. However, these are to be considered only as updates within the sixthversion with improved precision of the mandates and test methods.It is permitted to quote from these criteria (e.g. in procurements), provided that thesource is disclosed and the extent of the quotation is consistent with sound copyrightpractice.

2011-11-07 2011 Copyright TCO Development AB. All rights reserved.A.2 Visual ergonomicsToday computer displays are an essential tool for users in all kinds of environments.Good visual ergonomics is a very important aspect of quality that can also have adirect effect on the health, comfort and performance of the user.In developing requirements for visual ergonomics, the possible health effects ofvarious parameters have been taken into account. Other features that characterisegood quality displays have also been in focus for developing these criteria.TCO Development used three main methodologies to determine the suitable level foreach requirement and the test methods for the visual ergonomics part of the TCOCertified labelling program. One is based on acceptable visual levels, as determinedby scientific research. The second is based on statistics from tests carried out inaccordance with TCO Development, ISO, MPR regulations and from specializedVDU tests. The third way is based on manufacturers’ knowledge and experience,which is invaluable. Manufacturers, consumer groups and other organisations withinterests in the visual ergonomics field have contributed a great deal of valuableinformation and ideas throughout the development process.TCO Certified All-in-one Computers 2.09 (123)

2011-11-07 2011 Copyright TCO Development AB. All rights reserved.A.2.1Image detail characteristicsA.2.1.1Native display resolution requirementBackgroundImage quality is negatively affected by a low fill factor, visible “jaggies”, poorrendering of details, etc. All of these parameters are related to the resolution of thedisplay. For display resolution characteristics, it is important to take the viewingdistance into account.The viewing distance in this TCO criteria document is defined as 1.5 the displaydiagonal, but no less than 500 mm which could be considered as an absoluteminimum viewing distance for comfortable viewing. This means that the mandate onresolution is independent of the display size and viewing distance but dependent onthe display format. Only the display format needs to be known.DefinitionA pixel is the smallest addressable imaging element of the All-in-one computerdisplay capable of reproducing a full range of luminance and colours.The native display resolution is the number of pixels in the horizontal direction bythe number of pixels in the vertical direction that the display can present.ApplicabilityAll-in-one Computers.Test procedureSee B.2.1.1.References2, 36 and 44.Mandate:The pixel density shall be 30 pixels/degree visual angle.The following information shall be submitted with the application toTCO Development:A copy of a test report from a test laboratory approved by TCO Development.TCO Certified All-in-one Computers 2.010 (123)

Total Cost Of Ownership TCO defined TCO is defined to be the total cost to own and operate a piece of equipment over its useful life. Keysight has developed a TCO model for the Test and Measurement industry comprised of the two core elements of capital expenses (acquisition costs) and operating expenses.

An analysis of total cost of ownership (TCO) per link finds site rental and rates dominate, accounting for around half of the five year TCO. Operation and maintenance is around a quarter and equipment capex, a fifth. These proportions reveal that TCO is much more sensitive to site related costs than equipment pricing. Comparing technologies, we .
