Safety & EMC Standards & Block Requirements
Objectives
Introduction to Global Safety Standards
Introduction to Global Power & EMC Standards
Determine Applicable Power, Safety & EMC Standards
Update Product Level Requirements
Update Block Level Requirements as needed for mitigations
Determine Specific Protection Device Additions Needed for your Block Designs
If a particular hazard does NOT apply, you must justify why !!!

EMC Hazards & Mitigations
Deliverable 1: EMC Mitigation Slides (Team Deliverable)
You must guard your product against the following real world hazards
Electrostatic Discharges
Ambient or Stray Magnetic Field Energy
RF Electrical Field Energy
Interference of Your Product with Other Electronic Products
Poor Commercial Incoming AC Power Quality
Find and Document All the EMC Test Standards applicable to your product to provide reasonable test coverage against the above hazards (See Attached Table + EU Directive Lists)
Develop 1 page (minimum) Mitigation plans that include any design aspects as well as brief description of test plans to verify robustness (see template slides)
Identify which blocks are affected by design aspects and add appropriate requirements to those blocks
