4000V AC 2×MOPP · Leakage < 100 µA · ISO 13485 CoC — Details dielectric isolation (4000V AC 2×MOPP), patient leakage current limits, and ISO 13485 quality documentation for non-finished medical OEM components including 2×MOPP AC/DC power supplies, endoscope imaging sub-modules, and diagnostic interconnect harnesses.

1. Applicable International Standards & Regulatory Matrix

Standard / Directive	Jurisdiction & Scope	Technical Requirement & Acceptance Limit
IEC 60601-1:2005+A1+A2 (Ed. 3.2)	Medical Electrical Equipment Basic Safety	Mandates Two Means of Patient Protection (2×MOPP: 4000V AC dielectric withstand, ≥ 8.0 mm creepage, and ≥ 5.0 mm clearance) for BF (Body Floating) and CF (Cardiac Floating) applied-part power isolation.
ANSI/AAMI ES60601-1 & CAN/CSA-C22.2 No. 60601-1	US & Canadian Medical Safety Deviations	North American national deviations governing protective earth continuity, patient auxiliary current limits (≤ 100 µA normal / ≤ 500 µA single fault), and UL 94 V-0 flammability.
IEC 60601-1-2 (Ed. 4.1)	Medical Electromagnetic Disturbances & Immunity	Enforces 28 V/m proximity wireless RF immunity across 80 MHz–2.7 GHz alongside ±8 kV contact / ±15 kV air ESD protection and CISPR 11 Class B emissions.
ISO 13485:2016	Medical Devices Quality Management Systems	Requires accredited ISO 13485 factory quality management with full lot-level traceability across optocouplers, Y1 safety capacitors, and medical isolation transformers.
ISO 14971:2019 & RoHS/REACH	Component Risk Management & Material Safety	Component-level FMEA failure rate data for system integrators plus RoHS 3, REACH SVHC, and latex-free material declarations.

2. Engineering Verification Parameters & Lab Test Protocols

2×MOPP Dielectric Isolation & Creepage: 4000V AC (or 5656V DC) primary-to-secondary hi-pot withstand for 60 seconds without breakdown; ≥ 8.0 mm creepage and ≥ 5.0 mm air clearance at 250V AC working voltage.
Ultra-Low Earth & Touch/Patient Leakage Current: Earth leakage current < 150 µA–300 µA in normal condition; touch/patient leakage current < 100 µA (< 10 µA for CF-rated isolation barriers).
Non-Finished OEM Sub-Assembly Boundary: Supplied strictly as non-finished OEM components (power modules, camera sub-assemblies, internal harnesses) under ISO 13485 factory documentation; the downstream device manufacturer owns finished-device EU MDR or US FDA 510(k) registration.

3. Factory Shipment Technical Documentation Checklist
