Как можно проверить продукцию на соответствие стандарту RoHS? The RoHS Directive restricts the use of the six substances but does not specify how producers can comply or the requirements for market surveillance; this will be specified in national law. Two key principles of the Directive are:
Вернуться вверх Что такое RoHS Директива? RoHS stands for the "Restriction of the use of Certain Hazardous Substances in Electrical and Electronic Equipment" and applies to equipment put on the market from 1st July 2006. The Directive (2002/95/EC) restricts the use of 6 substances (lead, mercury, cadmium, hexavalent chromium and the 2 brominated flame retardants, PBB & PBDE). RoHS is closely linked to the WEEE Directive and takes its scope from it. Вернуться вверх Где находят ограниченные законом вещества?
The restricted materials can be found in a variety of different applications, including the following:
Вернуться вверх Каково определение электронного оборудования, разрешенного RoHS? RoHS affects specified types of EEE (Electrical and Electronic Equipment) and is defined in the WEEE Directive as: "Equipment which is dependent on electric currents or electromagnetic fields in order to work properly and equipment for the generation, transfer and measurement of such currents and fields falling under the categories set out in Annex IA and designed for use with a voltage rating not exceeding 1000 Volt for alternating current and 1500 Volt for direct current" Вернуться вверх Будут ли вся продукция, подтвердившая соответствие стандарту RoHS иметь новое название? A variety of different approaches have been taken to RoHS and part numbering:
Вернуться вверх Как я могу проверить оборудование на соответствие стандарту RoHS? There are various ways of testing for RoHS compliance, ranging from fairly simple methods to highly complex chemical analysis. Whichever technique is chosen it is important to ensure that it tests the "homogeneous material" and not the entire component or assembly. One of the most cost-effective methods of RoHS screening is a technique known as ED-XRF (electro dispersive x-ray fluorescence). In this technique the sample is excited with an x-ray beam and the resultant emissions collected and analysed. The emissions spectra can identify the presence and concentration of materials present. The technique does have some limitations, including
Вернуться вверх Можем ли мы все еще производить несоответсвующие продукты? Если продукт входит в список продуктов Директивы RoHS производство несоответствующей версии все еще является легальным, тем не менее вы не сможете продать такой продукт в ЕС начиная 1 июля 2006 года. На практике, спрос на несоответствующие продукты очень маленький. Вернуться вверх Есть ли различие между понятиями "не содержит свинца", "экологически чистый" и "соответствует стандарту RoHS"? These terms are often used interchangeably, but may not mean the same things. From a manufacturer's perspective there are two key aspects to component compliance:
Вернуться вверх Стандарт RoHS применяется только к новой продукции? Нет, данный стандарт применен к 8 категориям электронного оборудования с 1 июля 2006 года, как нового, так и того, что уже производился. Вернуться вверх Каково определение "Гомогенного Материала"? An homogeneous material has been defined as a material which can be mechanically separated from another material (e.g. through scraping or abrasion), without chemical separation. The "tinning" on a component lead is therefore an homogeneous material as it can be separated from the copper wire, whereas the Lead (Pb) contained in a ceramic cannot be separated from the ceramic by mechanical means. Another example of an homogeneous material is the plastic sheath on a cable. Вернуться вверх Я могу покупать и использовать компоненты, что не соответствуют стандарту? Non-compliant components may still be used for the repair of "historic" electrical equipment (i.e. put on the market before 1st July 2006). They may also be used in the manufacture and repair of products outside the scope of RoHS. The availability of non-compliant components will be dictated by the demand for them. For economic reasons component manufacturers will generally only produce one version of a component. If a significant proportion is used in the manufacture of new electrical equipment then the component is likely to be available only as "RoHS compliant". Certain components are only manufactured as spare parts for existing equipment and will therefore never be made compliant. Distributors may stock supplies of non-compliant components to support applications outside the scope of RoHS. This is likely to be a short-term situation as supplies will be limited. Вернуться вверх Какие страны поддержали стандарт RoHS? Где Директива RoHS применяется юридически? RoHS is an EU Directive and therefore only legally applies within the EU member states. However RoHS has a wider impact for 2 main reasons:
Вернуться вверх Does the RoHS Directive specify how compliant products should be marked? Unlike the WEEE Directive, RoHS does not specify a "compliance mark". A number of manufacturers now indicate compliance on product packaging by using symbols or a suffix to their part number (e.g. PBF, LF, or G). Вернуться вверх Что затронуто RoHS? The effects of RoHS are widespread. Legally it affects anyone who:
However the real impacts are far wider, RoHS has implications for many other parts of the supply chain including:
Вернуться вверх Каковы данные на соответствие стандарту RoHS? A RoHS compliant product is defined as not containing any of the restricted materials in concentrations exceeding the maximum permitted levels. i.e. 0.1% by weight for Lead (Pb), Mercury (Hg), Hexavalent Chromium (Cr [VI]), and the 2 brominated flame-retardants (PBB & PBDE) and 0.01% for Cadmium (Cd) in an homogeneous material. The RoHS Directive applies only to the specified categories of electrical products; it does not apply to the manufacture and sale of components. However, in order to manufacture compliant equipment, "compliant" components and lead-free solders will be required. It is important that the components used do not exceed these limits and (where necessary) are able to withstand the higher process temperatures required by lead-free solders. RS Components has obtained compliance information from its suppliers and taken all reasonable steps to confirm this before making it available to customers. Вернуться вверх Какова основная цель Директивы RoHS? RoHS should be considered in association with the WEEE Directive. Their objectives are jointly to improve environmental performance at all stages in a product's life cycle. Some of the materials used in electronics can present environmental and health hazards during manufacturing or at "end of life" disposal. The EU has therefore taken steps to restrict the use of these materials (RoHS) and encourage the safe disposal or re-use of electrical equipment (WEEE). Вернуться вверх Как это закон будет осуществляться? There is a key difference between the WEEE and RoHS Directives. WEEE specifies minimum standards that each member state must implement but may exceed. RoHS is a single market Directive, which means it must be implemented identically by each member state. Вернуться вверх Какие типы оборудования затронуты RoHS? The RoHS Directive takes its scope from Annex 2 of the WEEE Directive, but excludes 2 categories (Monitoring & Control and Medical devices). The range of affected products is listed below, further guidance is expected to be issued by national bodies responsible for implementing and enforcing the directives on a country by country basis (e.g the Department of Trade & Industry and National Weights and Measures Laboratory in the UK) Large Household appliances: - Large cooling appliances - Refrigerators & Freezers - Other large appliances used for refrigeration, conservation and storage of food - Washing machines - Clothes dryers - Dish washing machines - Cooking - Electric stoves - Electric hot plates - Microwaves - Other large appliances used for cooking and other processing of food - Electric heating appliances & electric radiators - Other large appliances for heating rooms, beds, seating furniture - Electric fans & air conditioner appliances - Other fanning, exhaust ventilation and conditioning equipment Small household appliances: - Vacuum cleaners - Carpet sweepers - Other appliances for cleaning - Appliances used for sewing, knitting, weaving and other processing for textiles - Irons and other appliances for ironing, mangling and other care of clothing - Toasters - Fryers - Grinders, coffee machines and equipment for opening or sealing containers or packages - Electric knives - Appliances for hair-cutting, hair drying, tooth brushing, shaving, massage and other body care appliances - Clocks, watches and equipment for the purpose of measuring, indicating or registering time - Scales IT and telecommunications equipment: - Centralised data processing: Mainframes, Minicomputers, Printer units - Personal computing: Personal computers (CPU, mouse, screen and keyboard included), Laptop computers (CPU, mouse, screen and keyboard included), Notebook and Notepad computers - Printers - Copying equipment - Electrical and electronic typewriters - Pocket and desk calculators and other products and equipment for the collection, storage, processing, presentation or communication of information by electronic means - User terminals and systems - Facsimile - Telex - Telephones, pay telephones, cordless telephones, - cellular telephones, answering systems and other products or equipment of transmitting sound, images or other information by telecommunications Electrical and electronic tools (with the exception of large-scale stationary industrial tools): - Drills - Saws - Sewing machines - Equipment for turning, milling, sanding, grinding, sawing, cutting, shearing, drilling, making holes, punching, folding, bending or similar processing of wood, metal and other materials - Tools for riveting, nailing or screwing or removing rivets, nails, screws or similar uses - Tools for welding, soldering or similar use - Equipment for spraying, spreading, dispersing or other treatment of liquid or gaseous substances by other means - Tools for mowing or other gardening activities Lighting equipment: - Luminaires for fluorescent lamps - Straight fluorescent lamps - Compact fluorescent lamps - High intensity discharge lamps, including pressure sodium lamps and metal halide lamps - Low pressure sodium lamps - Other lighting or equipment for the purpose of spreading or controlling light with the exception of filament bulbs Consumer equipment: - Radio sets - Television sets - Videocameras - Video recorders - Hi-fi recorders - Audio amplifiers - Musical instruments - And other products or equipment for the purpose of recording or reproducing sound or images, including signals or other technologies for the distribution of sound and image than by telecommunications Toys, leisure and sports equipment: - Electric trains or car racing sets - Hand-held video game consoles - Video games - Computers for biking, diving, running, rowing, etc. - Sports equipment with electric or electronic components - Coin slot machines · - Automatic dispensers Вернуться вверх Какие альтернативные решения для ограниченных веществ? There are various alternatives to the restricted substances, however none has exactly the same characteristics. Some of the most common alternatives are listed below:
Вернуться вверх Как поддерживается данный закон RoHS? Non-compliant components can be used to maintain or repair Electrical and Electronic Equipment (see 'What is the definition of EEE?') which is put on the market before 1st July 2006. Many components will not be available indefinitely in a non-compliant form. It is possible to make an acceptable tin/lead solder joint onto a "lead-free" component. Consequently repair of non-compliant EEE with compliant components should not normally cause any problems. The repair of non-compliant equipment with lead-free solders should be avoided if possible. Lead-free solders melt at higher temperatures than leaded solders and this may cause problems with existing solder joints and components. N.B. EEE put on the market after 1st July 2006 should only be repaired using compliant components and lead-free solder. Вернуться вверх Какова максимальная концентрация ограниченных законом веществ? The maximum concentrations by weight permitted in an homogeneous material are 0.1% for Lead (Pb), Mercury (Hg), Hexavalent Chromium (Cr [VI]) and the 2 brominated flame-retardants (PBB & PBDE), and 0.01% for Cadmium (Cd). Вернуться вверх I have heard that cutting and welding materials containing Chromium can create Hexavalent Chromium. Is this a problem? It appears that welding stainless steel or chromium plated steel produces toxic fumes which contain chromium trioxide (CrVI). This is possible as chromium metal will oxidise if heated and at welding temperature may make a small amount of CrVI. This must form as minute dust particles to exist in the hexavalent state because the oxide (CrO3) is unstable above its melting point, which is 197 deg C, decomposing to trivalent chromium oxide. There will not be Cr6 on the welded stainless steel surface because the steel will be too hot and any CrO3 that is present will decompose to CrIII. Вернуться вверх |
