ISO 23551-9:2015 specifies safety, constructional, and performance requirements and testing of mechanical gas thermostat for gas burners, gas appliances, and similar use hereafter referred to as "thermostats". ISO 23551-9:2015 covers type testing only. ISO 23551-9:2015 applies to mechanical gas thermostats of nominal connection sizes up to and including DN 50 with declared maximum inlet…

IEC 60939-3:2015 covers passive filters used to attenuate unwanted radio-frequency signals (such as noise or interference) generated from electromagnetic sources. Both single and multi-channel filters within one enclosure or which are built on a printed circuit board forming a compact entity are included within the scope of this specification. This specification applies to passive filter units…

L'IEC 60939-3:2015 couvre les filtres passifs utilisés pour atténuer les signaux aux fréquences radioélectriques indésirables (par exemple le bruit ou le brouillage) générés par des sources électromagnétiques. Les filtres à voie unique et à voies multiples à l'intérieur d'une enveloppe, ou montés sur une carte de circuit imprimé formant une entité compacte, font partie du domaine d…

ISO 21460:2015 defines the Proximity-1 Space Link Protocol Physical Layer. The specification for the channel connection process, provision for frequency bands and assignments, hailing channel, polarization, modulation, data rates, and performance requirements are defined in this document. Currently, the Physical Layer only defines operations at UHF frequencies for the Mars environment. The Data…

IEC PAS 62878-2-5:2015(E) defines the data format for active and passive devices embedded inside an organic board whose electrical connections are made by means of a via, electroplating, conductive paste or printing of conductive material. This PAS describes the expression of 3D data information, the concept of layers, the structure of board data, and definitions of information repeatedly used in…

ISO 16130:2015 applies to the dynamic testing of the locking behaviour of bolted connections in order to investigate the self-loosening behaviour of fasteners for aerospace applications and is mainly intended for development work. As test apparatuses are different (e.g. stiffness distribution), testing in accordance with this International Standard, therefore, does not allow an absolute statement…

IEC 60700-1:2015 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60700-1:2015 applies to thyristor valves with metal oxide surge arresters directly connected between the valve…

IEC 60700-1:2015 applies to thyristor valves with metal oxide surge arresters directly connected between the valve terminals, for use in a line commutated converter for high voltage d.c. power transmission or as part of a back-to-back link. It is restricted to electrical type and production tests. The tests specified in this standard are based on air insulated valves. For other types of valves,…

IEC 60700-1:2015 s'applique aux valves à thyristors équipées de parafoudres à oxyde métallique directement connectés entre les bornes des valves, qui sont destinées à être utilisées au niveau d'un convertisseur commuté par le réseau pour le transport d'énergie en courant continu à haute tension ou dans une liaison dos à dos. Elle est limitée aux essais de type électriques et de…
