TCO ' 99
There are two main groups of standards and guidelines - of safety and ergonomics. The standards UL, CSA, DHHS, CE, Scandinavian SEMRO, DEMKO, NEMKO and FIMKO concern to the first group, and also FCC Class B.From the second group the most known are MPR II, TCO ' 92 and TCO ' 95, ISO 9241-3, EPA Energy Star, TUV Ergonomie.
FCC Class B
Designed by a canadian Federal commission of the communications for support of acceptable environmental protection from influence of radiointerferences in the closed space. The equipment which is conforming the requirements FCC Class B, should not prevent the work of a TV and radio equipment.
MPR-II - system of standards, which regulate limitation on radiation from electrostatic, electrical and magnetic fields for computer and office technics, accepted SWEDAC (Swedish National Board for Measurement and Testing - by National department of standards of Sweden) in 1990 and predicated subsequently East Economic Community. The requirements MPR-II are taken into account during development of complex standards TCO.
The German analog TCO95. This standard is uncalculating by German government during some years for the denotation of "ecologically pure" production. The monitor with neat Blue Angel have correspond to the standard Energy Star on saving power, have a module construction for simplification of modernization and repair, inspected chemical composition, appropriate MPR II radiation levels, and constructive scheme which provide possibility for re-use. The manufacturer should also be ready to accept production back after an expiration of service life for destruction or processing.
Technical Supervision Bureau - private expert organization in Germanium, which certificate radio electronic equipments in Germanium. The authority of the company is indisputable, and the availability of an emblem TUV on a label means, that the corporation - manufacturer takes care of the reputation and does not spare resources for confirmation of high advantages of the goods.
TCO (The Swedish Confederation of Professional Employes, Confederation of professional unions of Sweden) - the association, one of activity directions of which is development of standards and guidelines for the hardware manufacturers of of IT-industry regulating interaction with an environment. In a basis of standards the most strong as fo today requirements to the characteristics of an item from the point of view of safety and minimum possible harmful influence on a man health are fixed. The standards TCO affect problems of protection from electrical and magnetic fields, noise and indirect heat liberations, survey questions power consumption and ergonomics, and also provide execution of a number of the ecological requirements in a part of used materials and raw material both in production, and at a stage of packing of final production. Last of a series of standards, announced October 29, 1998, has the name TCO ' 99. (For more details see http: // www.tco-info.com.)
The standard TCO ' 92 designed only for screen monitors and determines the maximal size of possible valid electromagnetic radiation by operation of monitor, and installed standard on the energy saving function for monitors.
The standard TCO ' 95 is spread to all personal computer, i.e. on monitor, system block and keyboard and have a deal with ergonomic properties, radiation (electrical and magnetic fields, hum and heat), energy saving modes and bionomics (with the requirement to necessary adapting of product and technological process of production at factory). The standard TCO ' 95 exists alongside with TCO ' 92 and does not cancel last.
TCO ' 99 presents the tighter requirements, than TCO ' 95 in the following areas: ergonomics (physical, visual and convenience of usage), energy, radiation (electrical and magnetic fields), environment and bionomics, and also fire and electrical safety. Also TCO ' 99 takes into consideration new methods of realization. The standard TCO ' 99 is spread on traditional CRT monitors, plainly panel monitors (Flat Panel Displays), portable computers (Laptop and Notebook), system blocks and keyboards.
The german standard of ergonomics. TUV Technical Supervision Bureau - private expert organization in Germanium, which certificate radio electronic equipments in Germanium. The authority of the company is indisputable, and the availability of an emblem TUV on a label means, that the corporation - manufacturer takes care of the reputation and does not spare resources for confirmation of high advantages of the goods.
The screen monitors adequate(answering) this standard, have passed tests according to EN 60950 (electrical safety) and ZH1/618 (ergonomic arrangement of work places equipped with displays), and also answer the Swedish standard MPR II.
EPA Energy Star VESA DPMS
According to this standard the screen monitor should to support three power economy modes: waiting (stand-by), suspension (suspend) and "sleep" (off). In a waiting mode the map on the screen disappears, but the internal components of the screen monitor function in the normal mode, and power consumption are reduced up to 80 percents from a working state. In the suspension mode high-voltage sites, as a rule, are disabled, and the power consumption impinges up to 30 watts and less. And at last, in so-called "sleep"-mode of the screen monitor consumes no more than eight watts, and the microprocessor functions for it only. At pressing any key of the keyboard or at a motion of the mouse the screen monitor passes in the normal mode of the work.
The Russian standard on videoscreen monitors of personal COMPUTERS. The requirements of this standard are mandatory for any screen monitor sold in Russian Federation. Besides, with this standard does not admit application explosive CRT, the grain size of the technical documentation on screen monitors is regulated, and also the requirements of standardization and unification, adaptability to manufacture, ergonomics and technical aesthetics, safety, technical repair and service, and also reliability are installed.
The screen monitors of personal computers and workstations at mandatory certification are exposed to certification tests on following parameters:
1) Parameters of safety - electrical, mechanical, fire (GOST 50377-92);
2) Sanitary-hygienic requirements - to a level of sound noises (GOST 26329-84 or GOST 2718-88), indexes ultra-violet, X-ray radiation and quality of the image (GOST 27954-88);
3) Electromagnetic compatibility - radiated radiointerferences (GOST 29216- 91).
The certificate is produced only on all complex set of aforesaid GOSTs.
In the present moment the state organization SERTINFO has issued certificates correspondence on screen monitors of corporations ALR, Funai, HP, IBM, Samsung, Siemens Nixdorf, Sony, ViewSonic. Unfortunately, we did not manage to receive the information about concrete models of the browse - it is known only, that practically all models Samsung, Sony and ViewSonic have passed the Russian certification, and Panasonic are prepare for doing this. All described models conform to the standards MPR II, FCC Class B, UL, CSA, TUV, CE, VCCI, EPA Energy Star.
