Compliance with the RoHS

What is RoHS?

The RoHS is one of the environmental directives, which stands for "the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment".

This Directive, which came into force on July 1, 2006 bans the placing on the EU market of any new electrical and electronic equipment containing more than the agreed level of the specified substances(cadmium, mercury, lead, hexavalent chromium, polybrominated biphenyl (PBB) or polybrominated diphenyl ether (PBDE)).

Covered Products

The RoHS Directive classifies the electrical and electronic equipment into ten categories. Products in categories 1 through 7 and 10 are currently the subject to this regulation (as of August, 2006). If products in these categories contain more than the agreed level of the specified substances, they will not be allowed to be placed on the EU market after July, 2006.

RoHS specified products

1. Large household appliancesRefrigerators, domestic washing machines, microwave ovens, air conditioners, etc.
2. Small household appliancesVacuum cleaners, irons, hair dryers, etc.
3. IT and telecommunications equipmentsPrinters, mini computers, PCs, etc.
4. Consumer equipmentsRadios, TVs, VCRs, audio amplifiers, musical instruments, etc.
5. Lighting equipmentsFluorescent lamps, discharge lamps, high-pressure sodium lamps, etc.
6. Electrical and electronic toolsElectric drills, lathes, lawnmowers, etc.
7. Toys, leisure and sports equipmentsRacing car sets, game machines, etc.
8. Medical equipmentsRadiotherapy equipments, electrocardiogram equipments, ventilators, etc.
9. Monitoring and control equipmentsGauges, monitoring and measuring equipments
10. DispensersHot drink dispensers, canned drink dispensers, etc.

Since the majority of our products (except some FA computers) are classified under category 9, "Monitoring and control equipments", they are not the subject to the RoHS Directive at this time (as of August, 2006). When our products are incorporated in other equipment, however, the classification of the equipment may change depending on the incorporated equipment. Please check whether the RoHS Directive applies to the incorporated equipment or not.

Maximum Allowable Content of the Six Substances Regulated by the RoHS Directive:

Maximum Allowable Content

Cadmium (Cd)100ppm
Mercury (Hg)1000ppm
Lead (Pb)1000ppm
Hexavalent chromium (Cr(VI))1000ppm
Polybrominated biphenyl (PBB) 1000ppm
Polybrominated diphenyl ether (PBDE) 1000ppm

Applications of specified hazardous substances which are exempted from the requirements

The following applications of specified hazardous substances are exempted from the requirements.

  1. Mercury in compact fluorescent lamps not exceeding 5 mg per lamp
  2. Mercury in straight fluorescent lamps for general purposes not exceeding:
    Halophosphate lamps10mg

    Triphosphate lamps with long lifetime8mg
  3. Mercury in straight fluorescent lamps for special purpose
  4. Mercury in other lamps not specifically mentioned in the above
  5. Lead in glass of cathode ray tubes, electronic components and fluorescent tubes
  6. Lead as an alloying element in steel containing up to 0.35 % lead by weight, aluminum containing up to 0.4 % lead by weight and as a copper alloy containing up to 4 % lead by weight
  7. Lead contained in the following goods:
    • Lead in high melting temperature type solders (e.g. tin-lead based solder alloys containing more than 85 % lead)
    • Lead in solders for servers, storage and storage array systems
    • Lead in solders for network infrastructure equipment for switching, signaling, transmission, as well as network management for telecommunication
    • Lead in electronic ceramic parts
  8. Cadmium plating except for applications banned under Directive 91/338/EEX amending Directive 76/769/EEC relating to restrictions on the marketing and use of certain dangerous substances and preparations
  9. Hexavalent chromium as an anti-corrosive in carbon steel cooling systems of absorption refrigerators

Exempted products

The following products are exempted from the requirements.

  1. Electrical and electronic equipment designed for use with a voltage rating exceeding 1,000 V for alternating current and 1,500 V direct current
  2. Electrical and electronic equipment for national security or military purposes
  3. Equipment whose main power source is not electricity
  4. Equipment that fulfills its primary function without electrical and electronic equipment
