This article serves as a comprehensive checklist for manufacturers seeking to certify their wire harnesses for North American markets.

Understanding UL and CE Certifications

UL Certification is specific to North America, verifying that products meet safety standards.

CE Marking is mandatory for products sold in the European Economic Area (EEA) but is also valued globally for safety assurance.

Step-by-Step Certification Checklist

1. Define Product Application and Environment

Industrial, consumer, automotive, or medical use?

Will the harness be exposed to vibration, heat, moisture, or chemicals?

2. Determine Applicable Standards

Ul 758: Standard for Appliance Wiring Material (AWM)

Ul 62: Flexible Cords and Cables

Ul 2556: Wire and Cable Test Methods

CE Directives: Low Voltage Directive (LVD), EMC Directive

3. Select Certified Components

Wires, jungtys, terminals, and jackets must be UL-listed or CE-approved

Avoid mixing uncertified parts to maintain the integrity of certification

4. Conduct Environmental and Mechanical Tests

Flammability (VW-1, FT1, FT2)

Temperature resistance

Chemical resistance

Bending and flex endurance

5. Perform Electrical Testing

Voltage withstand (HiPot)

Insulation resistance

Conductor resistance

Continuity verification

6. Compile Technical Documentation

Bill of Materials (BOM)

Wiring schematics

Testing protocols and results

Material safety data sheets (MSDS)

7. Engage with Certification Bodies

Ul: Apply via UL Prospector or UL Product iQ platform

CE: Conduct internal assessment or engage a Notified Body if required

Labeling and Traceability

UL Marking: UL logo, file number, and AWM style

CE Marking: CE logo, declaration of conformity

Batch/lot numbers for traceability

Common Pitfalls

Using non-compliant insulation materials

Missing documentation

Incomplete test reports
