TCO Certification
TCO certification by the Swedish Professional Employees Association (TCO, Swedish Federation of Professional Employees) to implement a display certification standards. Through this alliance made by the Swedish labor certification standards must be ecological (ecology), energy (energy), radiation (emissions) and ergonomics (ergonomics) are up to par four can. It is obvious from the four e, TCO certification is for human health and the environment the standards set,
nike air force one high, the display is directly related to the user's health.

authentication history certification standards for conditions affecting the meaning and significance of each period of significance of the difference between TCO TCO Certification standards for certification of the meaning of ecology (ecology) here mainly refers to the eco-environmental protection, TCO certified limits in this respect in the display of these harmful elements contained in the volume of products in order to achieve the effect of protecting the ecological environment.
TCO certification
Energy (energy) TCO in here has a special energy-saving regulations, such as requiring a computer and display device after a certain idle period can automatically reduce power consumption, and gradually into the saving state,
air force one low, and require products energy state back to normal from a shorter time. To ensure that energy is not wasted. Radiation (emissions) TCO some of its provisions in respect of radiation to ensure the health of users from infringement. Display manufacturers design products to be reduced when considering this aspect, try to make the product less harmful to human emission of radiation. Ergonomics (ergonomics) in order to display the user as comfortable as possible and easy fatigue, TCO for a variety of ergonomic features displays also make demands, such as a monitor of the Yang-government angle adjustment, whether the target so the brightness of the screen. TCO certification history, first introduced in 1992, the accreditation standards as TCO'92, followed launched TCO'95, TCO'99 and TCO'01 three certification standards, and always maintained a sustained spirit of updating the standard specifications, and the end of 2002 to determine the TCO'03 standard is the latest certification standards. Since the early 90s of last century is still the dominance of CRT monitors, so the first launch of the TCO'92 is actually a certification standard for CRT monitors. TCO'92 of electromagnetic radiation in the display, auto power off, power consumption and electrical safety on the fire and put forward specific requirements. TCO 92 certification requirements to obtain certification to the display areas subject to the following conditions: - monitor must be equipped with automatic shutdown. - Power companies must provide a description. This note should be pointed out that the display power consumption, and to guide the user to set the power saving features. - Monitor must meet the - Manufacturers should be entered into license agreements with TCO. TCO approved by the manufacturer must produce the certificate issued by a testing laboratory. Did not confirm the label affixed to monitor the quality of the environment, TCO will be commercially available products sampling. The impact of influence and significance of the TCO'95 available in 1995,
nike air force 1, extended to put the keyboard, mouse, host, laptops, printers, etc., on the basis of the TCO'92 Environmental and Ergonomic joined the design specifications and requirements equipment, ergonomic, and strictly limit radiation (in addition to electromagnetic fields, but also including noise and heat.) At this point the TCO'95 certified electrical products began to be more respect for national and regional environmental favor and influence gradually expanded. Really familiar with our consumers TCO TCO'99 none other than non-certified natural, which emphasizes the display content of toxic substances in products, materials control, and set strict product recovery process. Principles of CRT displays with the different structure of the LCD and other flat panel display devices (Flat Panel Display,
air force one high, FPD) monitor market share in the growing, TCO'99 CRT and FPD for the first time the requirements will be separated. TCO'01 certification standards introduced in recent years specifically for GSM mobile phones, its demanding, not broad scope,
air force 1 high, timing and other factors is not long, not many people understand it. TCO series certification standards with the aim has always been the same, TCO'01 focus on mobile phone electromagnetic radiation, ergonomics and environmental protection has made detailed provisions. TCO'99 launched several years after the advent of the TCO'03 is a new certification standards. TCO 03 announced the end of 2002, with the LCD monitor on the market share occupied by more and more, TCO'03 FPD began to focus on aspects of the gradual shift,
air force one low nike, which makes the TCO'03 looks more like a tailor for the LCD -made specification. The first launch of the new century as an authoritative display product certification standards, and its effects are increasingly being used by more vendors. TCO 99 and TCO 03 will compare you will find, TCO 03 is indeed time for the custom LCD. Because CRT and FPD itself technically different, TCO'03 standard feature in new technology focuses a lot on the new definition. However, the appearance does not mean to subvert the TCO 03 TCO 99 standard, in fact, the standard in the definition of the CRT monitor on, TCO'03 TCO'99 standards generally continued, and in the geometric properties such as the screen, electrical safety, static electricity voltage and other basic indicators and there is no change; and even some of the original TCO 99 standard for specific indicators for the CRT display design but was removed, such as X-rays. LCD monitor TCO 03 meaning the most significant for the definition and brightness levels in this always is the large LCD monitor key indicators between the large Dazui Zhang. TCO 99 standards for not less than the maximum brightness of 125cd/m2, and TCO 03 is raised to 150cd/m2, for those who use the two-lamp LCD is undoubtedly a great challenge, or add behind the lamp, or to add 3M manufacturing backplane physical brightening. The pixel density from the TCO 99 index number of the simple filling of not less than 0.5, from 1024 on to the TCO03 * 768-1600 * 1200, but the distance requirement 50CM pixel density of not less than 30pixel/degree. Brightness uniformity issues also changed, TCO 99 of the maximum brightness and minimum brightness variation of more than 1.7:1 1.5:1 palate TCO 03, which place more emphasis on the consistency of the color screen brightness, reducing the brightness of the screen corners and the center inconsistent gap. TCO standards are always special emphasis on ergonomics, not only to see that the eyes comfortable, but also Debu tired to the neck and shoulders, TCO 99 and did not make the definition of vertical tilt of the screen, so that all the CRT monitors are down 12 early renewal degree tilt of the end of care, while LCD is even more For a more strict ecological protection, not only the most basic need to TCO 99 indicators on recycling, the production plant but also through ISO14001 certification, and also signed a recycling contract, which undoubtedly is a factory not attach importance to environmental protection stern warning. TCO certification period the difference between the TCO92: reduce electromagnetic radiation, save electricity, fire and power; & nbs p; TCO95: coverage involves monitor, keyboard and system unit. In addition to the provisions of TCO92, but also put forward the requirements of environmental protection, and require equipment, ergonomic; TCO99: based on an increase in the TCO95 recyclable material requirements, the purpose is to enable users to feel the greatest degree of comfortable as possible while protecting the environment TCO03: TCO'03 mainly for the LCD monitor. The main difference is in terms of CRT brightness and uniformity of the screen is more stringent. Deadline May 27, 2003, through the TCO'92 (now the certification has stopped) certified display models up to 1050, TCO'95 and TCO'99 certified by the display model for the 2085 and 2286; and TCO'03 certified by the latest display model was only 61, even to the middle of 2004, TCO'03 certified through the model is still limited. The reason why the model through the few, mainly because the standard TCO model of strict control of the display, even if the display is a model certified by the TCO, as long as the changes that look to be the new certification, and must test the product to the TCO room for further tests. Some brands of the same model monitor TCO'03 certified by a white shell, and black only through the TCO'99 (black display case is in fact not contain harmful substances, the current black and white plastic can do the physical indicators have been almost identical, only because black color contrast between the shell and the screen too), so they see a black display by TCO'03, then it must be ########! There are display case material. Because when the monitor through the TCO certification standards, the raw material will be changed from the original non-toxic harmless ABS ABS + PC material, the material can be injection molded to verify the number as a reference to distinguish between true and false. TCO TCO in terms of certification and promotion of the major display manufacturers, TCO certification greatly enhance the charm, and many products have to pass a stringent TCO certification as a selling point, TCO03 certification in this case reached the pinnacle of the launch point. However, please be assured through such a rigorous certification is not easy. As ordinary consumers, without reference to more certification and technical indicators, as long as a TCO certification mark is enough to prove a product in the health, environmental protection is trustworthy. We are concerned about TCO certification mark, which is the certification of high demand, easy to identify, influence a wide range of closely related; another perspective, largely because of health concerns, TCO flag manufacturer to the consumer like a In this sense, TCO certification for consumers to buy CRT monitors one of the most important reference. Since the display a great impact on the TCO standard, then is not certified by TCO in the market circulation can display it? No, for in the domestic production and sales of video products are concerned, 3c certification mandatory certification is the only to cross the threshold. 3c certification is the The purpose is to strengthen the implementation of product safety, environmental monitoring, to ensure that the interests of consumers. 3c certified English name The certification is the new generation of electromagnetic compatibility standards, without the standard certification of electrical products on sale are not allowed.
