Fibre optic active components and devices. Performance standards - Seeded reflective semiconductor optical amplifier devices Ingestion-build-52208 Products can only be tested

Products can only be tested at a concentration of 80 % or less (97 % with a modified method for special cases) as some dilution is always produced by adding the test organisms and interfering substance

European standards relating to steels complying with the requirements for the chemical composition outlined but that are supplied in other product forms or treatment conditions than given

For coupling attenuation

The method is suitable for specimens which are laboratory compacted or specimens cut from the pavement after placement and compacting or from laboratory compacted slabs

The system operator or owner is responsible for specifying requirements for the connection of disturbing installations to the system
