Hazard-Based Safety Engineering (HBSE): Per IEC 62368-1. New methodology. Identifies energy sources + classifies energy + prescribes safeguards + defines energy transfer limits.

HBSE philosophy: Treats safety as universal across IT + AV + ICT + IoT. Generic approach. Different from IEC 60950-1 (prescriptive). HBSE focuses on what to achieve + how to verify rather than how to implement.

HBSE process per IEC 62368-1: (1) Identify energy sources. (2) Classify each energy source (ES1 / ES2 / ES3). (3) Identify safety measures (basic + reinforced + supplementary + additional). (4) Implement safeguards. (5) Verify compliance. (6) Document in safety file.

Energy sources per IEC 62368-1: Electrical + thermal + radiation (laser + light + RF) + mechanical + chemical + kinetic. Each source can transfer energy to body part + cause injury.

Body part consideration per IEC 62368-1: Determine body part that could be exposed to energy source. Limits differ per body part. E.g., ear exposure to acoustic energy vs whole body.

Geographic adoption: Adopted as UL 62368-1 (US) + EN IEC 62368-1 (EU) + GB 4943.1 (China) + JIS C 62368-1 (Japan) + CAN/CSA C22.2 No. 62368-1 (Canada) + AS/NZS 62368.1 (Australia + New Zealand).

Required for: CE LVD (EU) + NRTL (US) + CCC (China) + PSE (Japan) + cCSAus (Canada) + RCM (Australia + New Zealand).

B2B relevance: For B2B protective cases containing IT + AV + IoT + edge + networking equipment, IEC 62368-1 compliance is procurement requirement for CE + UL + CCC + PSE + cCSAus + RCM.
