Fibre optic interconnecting devices and passive components performance standard - Non-connectorised single-mode bidirectional 1490 / 1550 nm downstream 1310 nm upstream WWDM devices for category C. Controlled environment1 Scope This part of IEC 61753 contains the minimum initial performance, test and measurement requirements and severities which a fibre optic pigtailed 1 490 1 550 nm downstream and 1 310 nm upstream wide wavelength division multiplexing (WWDM) passive optical network (PON) device must satisfy in order to be categorized as meeting the requirements of category C (controlled environments), as defined in Annex A of IEC 617531. Annex B of this standard

accuracy decreases with an increasing loss in mass

you can perform the inspection to detect flaws in weld quality

and to avoid unnecessary repetition

ISO 2063-1 on thermal spraying of zinc

This document specifies the performance requirements for metal halide lamps for general lighting purposes

BS EN 60761-5 on Equipment for continuous monitoring radioactivity in gaseous effluents is relevant to:

fits where the design torque is transmitted by interfacial friction are not considered as these require detailed individual study

Evaluating the dimensional properties of plastics is crucial in determining the performance
