Tests on electric and optical fibre cables under fire conditions - Tests for vertical flame propagation for a single small insulated wire or cable. Procedure for diffusion flame Ingestion-build-81111 prEN ISO 9934-21 Scope This part of IEC 60332 specifies the procedure for testing the resistance to vertical flame propagation for a single small vertical electrical insulated conductor or cable, or optical cable, under fire conditions. The apparatus is given in IEC 6033221. This standard gives the procedure for testing small optical fibre cables or a small insulated conductor or cable when the method specified in IEC 6033212 is not suitable because some small
