How do I verify the authenticity of an LSZH cable?

Genuine LSZH cables will have the relevant standards (e.g., BS EN 50267 or IEC 61034) printed directly on the jacket. Professional buyers often request a Burn Test Report or a Certificate of Compliance (CoC) to verify that the halogen content is indeed below the 0.5% threshold required for a “Zero Halogen” rating.
