Ingrédients de mélange du caoutchouc — Noir de carbone — Détermination de l'indice d'absor...
L'indice d'absorption d'huile (OAN) est une mesure de la capacité du noir de carbone à absorber des liquides. Cette propriété est elle-même fonction de la structure du noir de carbone. Le phtalate de dibutyle (DBP) ou l'huile de paraffine peuvent être utilisés avec les qualités de granules de référence, y compris les noirs de carbone de série N spécifiés dans l'ASTM D1765…
Rubber compounding ingredients — Carbon black — Determination of oil absorption number (OAN) and oil...
Oil absorption number (OAN) is a measure of the ability of a carbon black to absorb liquids. This property is a function of the structure of the carbon black. Either dibutyl phthalate (DBP) or paraffin oil is acceptable for use with standard pelleted grades, including N‑series carbon blacks found in ASTM D1765, although OAN testing using paraffin oil on some speciality blacks and powder blacks…
Industrial communication networks - High availability automation networks - Part 3: Parallel Redunda...
IEC 62439-3:2012 specifies two redundancy protocols designed to provide seamless recovery in case of single failure of an inter-bridge link or bridge in the network, which are based on the same scheme: duplication of the LAN, resp. duplication of the transmitted information. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. The main…

1 Scope
This part of IEC 61000 relates to the immunity requirements of equipment, only under
operational conditions, to magnetic disturbances at power frequencies 50 Hz and 60 Hz
related to:
– residential and commercial locations;
– industrial installations and power plants;
– medium voltage and high voltage sub-stations.
The applicability of this standard to equipment installed in different…
Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-09...
IEC 61010-2-091:2012 specifies particular safety requirements for CABINET X-RAY SYSTEMS. A CABINET X-RAY SYSTEM is a system that contains an X-ray tube installed in a cabinet which, independently of existing architectural structures except the floor on which it may be placed, is intended to contain at least that portion of a material being irradiated, provide radiation attenuation, and exclude…
Electronic railway equipment - Train communication network (TCN) - Part 3-3: CANopen Consist Network...
IEC 61375-3-3:2012 specifies the data communication bus inside consists that are based on CANopen. CANopen was developed for use in, but is not limited to, industrial automation applications. These applications may include devices such as input/output modules, motion controllers, human machine interfaces, sensors, closed-loop controllers, encoders, hydraulic valves or programmable controllers.…
Non-destructive testing — Qualification and certification of NDT personnel
This International Standard specifies requirements for principles for the qualification and certification of personnel who perform industrial non-destructive testing (NDT).
The system specified in this International Standard can also apply to other NDT methods or to new techniques within an established NDT method, provided a comprehensive scheme of certification exists and the method or technique…
Rubber compounding ingredients — Carbon black — Determination of specific surface area by nitrogen a...
This International Standard specifies four methods for the determination of the specific surface area of types
and grades of carbon black for use in the rubber industry:
— method A using the Ni‑Count‑1 apparatus (Clause 3);
— method B using the Areameter apparatus (Clause 4);
— method C using gas chromatography (Clause 5);
— method D using the Monosorb surface-area analyser (Clause 6).
