Provides the minimum requirements and severities which a fibre optic connector terminated on multimode fibre must satisfy in order to be considered as meeting the IEC standard category C - controlled environment, as defined in annex A of IEC 61753-1-1.

Presents procedures for the measurement of the return loss (RL) of a fibre optic device under test (DUT). RL, as used in this standard, is the ratio of the power (Pi) incident on, or entering, the DUT to the total power reflected (Pr) by the DUT, expressed in decibels.

Applies to telecontrol equipment and systems with coded bit serial data transmission for monitoring and controlling geographically widespread processes. Defines a telecontrol companion standard that enables interoperability among compatible telecontrol equipment. The defined telecontrol companion standard utilizes standards of the IEC 60870-5 series of documents. This publication is of high…

IEC 61754-6-1:2003 defines the standard interface dimensions of simplified receptacles for the type MU family of connectors. Keywords: interface dimensions of simplified receptacles for type MU connectors.

ISO 9096:2002 describes a reference method for the measurement of particulate matter (dust) concentration in waste gases of concentrations from 20 mg/m3 to 1000 mg/m3 under standard conditions. ISO 9096:2002 is applicable to the calibration of automated monitoring systems (AMS). If the emission gas contains unstable, reactive or semi-volatile substances, the measurement will depend on the…

ISO 3581 specifies requirements for classification of covered electrodes, based on the all-weld metal chemical composition, the type of electrode covering and other electrode properties, and the all-weld metal mechanical properties, in the as-welded or heat-treated conditions, for manual metal arc welding of stainless and heat-resisting steels. It is a combined standard providing for…

Provides the method to measure the coupled power ratio (CPR) coefficient. The CPR coefficient may be measured at both 850 nm and 1 300 nm wavelengths. CPR measurements are used to characterise optical sources and to standardize the launch conditions for measurements of attenuation on multimode fibres and inseration loss according to IEC 61300-3-4.
