Congratulations! You have just purchased aTCO’99 approved and labeled product! Your choicehas provided you with a product developed forprofessional use. Your purchase has alsocontributed to reducing the burden on theenvironment and also to the further development ofenvironmentally adapted electronics products.Why do we have environmentally labelled computers?In many countries, environmental labelling has become anestablished method for encouraging the adaptation of goods andservices to the environment. The main problem, as far ascomputers and other electronics equipment are concerned, is thatenvironmentally harmful substances are used both in the productsand during the manufacturing. Since it has not been possible forthe majority of electronics equipment to be recycled in asatisfactory way, most of these potentially damaging substancessooner or later enter Nature.There are also other characteristics of a computer, such as energyconsumption levels, that are important from the viewpoints of boththe work (Internal) and natural (external) environments. Since allmethods of conventional electricity generation have a negativeeffect on the environment (acidic and climate-influencingemissions, radioactive waste, etc.), it is vital to conserve energy.Electronics equipment in offices consume an enormous amount ofenergy since they are often left running continuously.What does labelling involve?This product meets the requirements for the TCO’99 schemewhich provides for international and environmental labelling ofpersonal computers. The labelling scheme was developed as ajoint effort by the TCO (The Swedish Confederation of ProfessionalEmployees), Svenska Naturskyddsforeningen (The SwedishSociety for Nature Conservation) and Statens Energimyndighet(The Swedish National Energy Administration).The requirements cover a wide range of issues: environment,ergonomics, usability, emission of electrical and magnetic fields,energy consumption and electrical and fire safety.The environmental demands concern restrictions on the presenceand use of heavy metals, brominated and chlorinated flameretardants, CFCs (freons) and chlorinated solvents, among otherthings. The product must be prepared for recycling and themanufacturer is obliged to have an environmental plan which mustbe adhered to in each country where the company implements itsoperational policy. The energy requirements include a demand thatthe computer and/or display, after a certain period of inactivity,shall reduce its power consumption to a lower level in one or morestages. The length of time to reactivate the computer shall bereasonable for the user.Labelled products must meet strict environmental demands, forexample, in respect of the reduction of electric and magnetic fields,physical and visual ergonomics and good usability.Environmental RequirementsFlame retardantsFlame retardants are present in printed circuit boards, cables,wires, casings and housings. In turn, they delay the spread of fire.Up to thirty percent of the plastic in a computer casing can consistof flame retardant substances. Most flame retardants containbromine or chloride and these are related to another group ofenvironmental toxins, PCBs, which are suspected to give rise tosevere health effects, including reproductive damage in fisheatingbirds and mammals, due to the bioaccumulative* processes. Flameretardants have been found in human blood and researchers fearthat disturbances in foetus development may occur.TCO’99 demand requires that plastic components weighing morethan 25 grams must not contain flame retardants with organicallybound chlorine and bromine. Flame retardants are allowed in theprinted circuit boards since no substitutes are available.Lead**Lead can be found in picture tubes, display screens, solders andcapacitors. Lead damages the nervous system and in higherdoses, causes lead poisoning.TCO’99 requirement permits the inclusion of lead since noreplacement has yet been developed.Cadmium**Cadmium is present in rechargeable batteries and in thecolourgenerating layers of certain computer displays. Cadmiumdamages the nervous system and is toxic in high doses.TCO’99 requirement states that batteries, the colourgeneratinglayers of display screens and the electrical or electronicscomponents must not contain any cadmium.Mercury**Mercury is sometimes found in batteries, relays and switches,Mercury damages the nervous system and is toxic in highdoses.TCO’99 requirement states that batteries may not contain anyMercury. It also demands that no mercury is present in any ofthe electrical or electronics components associated with thedisplay unit.CFCs (freons)CFCs (freons) are sometimes used for washing printed circuitboards. CFCs break down ozone and thereby damage the ozonelayer in the stratosphere, causing increased reception on Earthof ultraviolet light with consequent increased risks of skin cancer(malignant melanoma).The relevant TCO’99 requirement; Neither CFCs nor HCFCsmay be used during the manufacturing and assembly of theproduct or its packaging.*Bio-accumulative is defined as substances which accumulatewithin living organisms.**Lead, Cadmium and Mercury are heavy metals which areBio-accumulative.To obtain complete information on the environmental criteriadocument, order from:TCO Development UnitSE-114 94 StockholmSWEDENFAX Number: +46 8 782 92 07E-mail (Internet): development@tco.seYou may also obtain current information on TCO’99 approvedand labelled products by visiting their website at:http://www.tcodevelopment.comTCO’9900Cover_all.p65 16/10/02, 5:16 pm3
