Optical amplifier technical reports - Theoretical background for noise figure evaluation using the electrical spectrum analyzer Ingestion-build-232773 BS EN 868 Part 7

BS EN 868 Part 7 of this series of European Standards specifies general requirements and test methods for all packaging materials and systems intended for use as packaging for medical devices which are to be terminally sterilized in their packaging

By using BS IEC 62951-4

Bolt and nut assemblies according to this standard include washers according to EN 14399-6 or to EN 14399-5 (under the nut only)

they are based on steels having a sound velocity of (5 920 ± 50) m/s for longitudinal waves
