ELECTRICAL SAFETY COMPLIANCE
WHY?
3
ELECTRICAL SAFETY COMPLIANCE

• public safety
• government requirement
• liability
• marketing
• consumer choice
• dead customers cant buy more stuff
• and . . . .

4
ELECTRICAL SAFETY COMPLIANCE
BECAUSE! Someone will find a way to use your
product in a way that you didnt 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
• Pgt15W potential fire hazard
• Igt0.5mA reaction / Igt10mA cant let go
• 0.45µC _at_ gt 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
