You can’t visit the factory — but you still need to verify IEC 60794 compliance. Remote verification is possible with the right documentation and video evidence.
Required Documentation
- Type-test certificate for the exact cable construction
- Factory OTDR traces per drum
- ISO 9001 certificate (current)
- Incoming material inspection records (preform, aramid yarn)
- Production traveler for your order
Red Flags
- Manufacturer refuses raw OTDR .sor files — only summary reports
- Type-test certificate older than 5 years
- Preform batch certificates don’t match production dates

Key Takeaways
- Remote verification requires more documentation than an on-site audit — demand complete records.
- Third-party inspection agencies can perform remote witness testing as a compromise.
