Optical fibres - Measurement methods. Damp heat (steady state) tests Ingestion-build-81111 PD 6550 has been written

PD 6550 has been written to assist both the newcomer to pressure vessel design and the experienced vessel designer

Lower fractions (down to 1 × 10−8) can be achieved by multi-stage dilution or by the use of gas mixtures as input gases

BS EN 2591-508 specifies methods of measuring the thickness of electro-deposited gold or gold alloys coatings on contacts of elements of connection

two methods can be compared only if the limits of these methods (calculated by using this part of ISO 12828) are similar for the lower range of concentrations to be measured

Optical fibres - Measurement methods. Damp heat (steady state) tests Ingestion-build-81111 PD 6550 has been written1 Scope This part of IEC 60793 provides a practical method for evaluating fibre performance in a defined environment. The purpose of this standard is to determine the suitability of optical fibre sub category A1a to A1d multimode fibres and class B and C single mode fibres to withstand the environmental condition of high humidity and high temperature which may occur in actual use, storage and or transport. The test is primarily intended to permit the
