  2. ELECTRICAL SAFETY COMPLIANCE WHY?

  3. ELECTRICAL SAFETY COMPLIANCE • public safety • government requirement • liability • marketing • consumer choice • dead customers can’t buy more stuff • and . . . .

  4. ELECTRICAL SAFETY COMPLIANCE BECAUSE! Someone will find a way to use your product in a way that you didn’t intend it to be used

  5. STANDARDS WHY? • Consistency • Compatibility • Safety • Risk mitigation

  6. STANDARDS • Standards evaluate specific hazards • Hazards may be unique to class of product. ie: electro-medical products 2-part series • part-1 general requirements • 50+ ‘part 2’ product-specific requirements • CSA 2500 published standards • 350+ electrical / electronic

  7. STANDARDS STANDARDS DEVELOPMENT • Written by consensus • Representation from: • industry • standards committees • academics • special interest groups

  8. STANDARDS ELECTRICAL / ELECTRONIC • consumer • industrial / commercial • information technology • audio/video • electro-medical

  9. STANDARDS HARMONIZED STANDARDS • International Electrotechnical Commission - IEC • Adopted internationally • National Standards • Global Market • Reduced compliance costs

  10. HAZARDS TYPES OF HAZARD • fire • electric shock • energy • burn • physical • or . . .

  11. HAZARDS . . . a complete lack of common sense

  12. HAZARDS ELECTRICAL • supply • 120V, 15A nominal • 30A / 2m before breaker trip • up to 20kA momentary fault • hazard limits • P>15W = potential fire hazard • I>0.5mA = reaction / I>10mA = can’t let go • 0.45µC @ > 60V = hazardous charge • human physiology controlled by electrical impulses • conflicting impulses can cause fibrillation or arrest

  13. COMPLIANCE STRATEGIES FOR COMPLIANCE • Design compliance into product • Test before applying for evaluation • Preliminary consultation (TIS)

  14. COMPLIANCE STRATEGIES FOR COMPLIANCE • Creepage distance & clearance • layers of insulation • Fault protection • ‘Double’ protection

  15. CERTIFICATION PURPOSE • Independent evaluation by an accredited organization • Statement of compliance • Access to market(s) • On-going conformity assessment • Marketing

  16. CERTIFICATION PRODUCT EVALUATION • Physical examination • Testing • Normal operation • Fault conditions • Documentation • Descriptive Report for inspections • Certificate and product listing for client

  17. CERTIFICATION FOLLOW-UP • Annual fees • Factory Inspections

  18. INTERNATIONAL CB Scheme • International agreement • Harmonized standards • Common report format • Issue local certification mark • Global Market • Reduced compliance costs

  19. INTERNATIONAL CE: Self-Declaration • European Union countries • Product specific Directives • Electronic: Low Voltage Directive • Safety and EMC • Self-Declaration

  20. INTERNATIONAL WEEE Directive • Waste Electrical and Electronic Equipment • EU Member countries • Landfill content • Producer responsible for recycling costs • Manufacture with ‘friendly’ materials • Will become CE Mark requirement

  21. ELECTRICAL SAFETY COMPLIANCE PURPOSE • compatibility • safety • risk mitigation • and . . .

  22. ELECTRICAL SAFETY COMPLIANCE You know they’re out there . . .
