TCO Certification
                                     

★ TCO Certification

The TCO Certified certification was originally created by the Swedish Confederation of professional employees to ensure that computer products purchased by employers meet environmental standards and are ergonomic enough to prevent long-term health problems for users. It came to prominence in the 1990s as the certification of computer displays. Since 1992, TCO has been one of the oldest certifications for end-user electronics.

                                     

1. History. (История)

In the early 1980s, the Swedish Confederation of professional employees (TCO), a workers trade Union, foresaw that computers would become an important work utility, and sought to establish ergonomic and radiation standards for computer displays to protect its members from health problems through daily use. At the same time, the increasing use of computers and monitors in white-collar work environments has led to widespread complaints from employees experiencing visual fatigue and visual stress during off-duty hours, also called "VDU disease". In fact, the first generations of computer displays were often associated with eye strain and headaches due to flickering, shaking, and radiation. In 1986, the TCO published a basic list of requirements and testing protocols to test whether the display is suitable for continuous daily use as an aid for employers to choose the right equipment for their workplaces.

This test was an early success and has been translated into several languages, as well as used by trade unions in other countries to provide a more ergonomic working environment. The success of the display checklist led to the creation of TCO Certified, a spin-off of the TCO Union, led by, among others, per Erik Boivi and Peter Magnusson, with the goal of creating international certification and standards that will be implemented directly by manufacturers. Since TCO92 in 1992, minimum TCO certification standards for emissions, jitter and electronic security for computer monitors. Later, the standards moved to other product categories, such as peripherals and the computer itself.

                                     

2. Certified requirements for the TCO. (Сертифицированные требования к ТШО)

Since 1992, TCO has published new guidelines every 3-4 years. The standards have expanded from covering only computer monitors in 1992 to a wide range of devices today.

                                     

2.1. Certified requirements for the TCO. TCO92

In collaboration with the Swedish nature conservation society, the Swedish Agency for economic and regional growth and ETL SEMKO, the first generation of certified TCO-TCO92 was created. TCO92 made automatic power-off mandatory for displays, which significantly increased the spread of energy-saving features. TCO92 combined standards, such as IEC 60950 for electrical and fire safety, with specific TCO emission limits.

                                     

2.2. Certified requirements for the TCO. TCO95

In 1995, the next generation of certified TCO was released-TCO95. TCO95 expanded the scope of TCO certification from display units to the computer and keyboard itself, also covering ergonomic aspects in addition to all the requirements already outlined in TCO92. TCO95 also significantly tightened environmental standards by requiring manufacturers to eliminate certain CFCs or HCFCs from production, in addition to removing chlorine solvents and any ozone-depleting compounds from production. By extending the requirements also to peripherals such as keyboards, ergonomics has become the standard of orthogonality, in addition to subjects such as the jitter and flicker of displays.

                                     

2.3. Certified requirements for the TCO. TCO99

TCO99 saw further tightening of requirements for energy conservation and energy consumption. While the requirements for radiating radiation remained unchanged, test reports were tightened to reduce the variability of test results. TCO99 has further tightened display requirements in terms of brightness and flicker / jitter in addition to introducing new text clarity requirements to ease eye stress due to display usage. In addition, noise restrictions have been introduced for displays.

TCO99 also provides for the introduction of rules that facilitate waste recycling. The offer of recycling and trade-in procedures became mandatory for manufacturers, which later became mandatory by the European Union for all sellers of electric consumer goods. Plastic components weighing more than 100 grams 3.5 ounces should be reduced to a single type of plastic, reducing the problems with separating different components during recycling.



                                     

3. Product category. (Категория продукта)

The TCO certificate is available for the following products: displays, laptops, tablets, smartphones, desktops, mainframe PCs, projectors, headsets, and data center products: network hardware, storage products, and servers.
