5) Safety/standards and labeling

• Regulatory: UL 94 is a material flammability test; product certification (UL, CE, IEC 60950/62368 for IT equipment) may require additional testing/documentation.
• Markings on PCB: include safety-relevant markings per the product standard (e.g., mains isolation barriers, fuse ratings). The “94V-0” marking itself is often printed on the PCB silk to indicate substrate rating (e.g., “94V-0” near board edge or on silkscreen) — verify customer or regulatory expectations.
• Documentation: maintain a Compliance File with material certificates, supplier declarations, and test reports.
