IEC IEEE 60076-57-1202:2017 covers the requirements for phase-shifting transformers of all types. The scope excludes transformers with an unregulated phase shift. This document is limited to matters particular to phase-shifting transformers and does not include matters relating to general requirements for power transformers covered in existing standards in the IEC 60076 series or IEEE Std C57.12…

ISO/TS 16774-1:2017 specifies a laboratory test method for evaluating the thermal stress resistance of water-leakage crack repair materials through permeability testing. The repair material injected into a test specimen with an artificial crack is thermally stressed under the applied temperature conditions outlined in different national testing parameters that reflect different environmental…

ISO/TS 16774-5:2017 specifies a laboratory test method for evaluating watertightness of water-leakage crack repair materials through permeability testing. These permeability test procedures follow applied conditions outlined in different national testing parameters and requirements. As such, the results are only intended to provide a comparative performance evaluation of the waterproofing repair…

ISO/TS 16774-6:2017 specifies a laboratory test method for evaluating the substrate (crack) movement response of water-leakage crack repair materials through permeability testing. The repair material injected into a test specimen with an artificial crack undergoes simulated movements normally caused by thermal expansion, settlement and vibrations in leakage cracks found in concrete structures…

IEC 60092-376:2017 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 60092-376:2017 is applicable to screened and unscreened cables for control and instrumentation circuits on…

IEC 60092-376:2017 is applicable to screened and unscreened cables for control and instrumentation circuits on ships and offshore units. The cables have extruded solid insulation with a voltage rating of 150/250V (300V) and are intended for fixed installations. The various types of cables are given in Clause 5. The constructional requirements and test methods are aligned with those indicated in…

IEC 62909-1:2017 specifies general aspects of bi-directional grid-connected power converters (GCPC), consisting of a grid-side inverter with two or more types of DC-port interfaces on the application side with system voltages not exceeding 1 000 V AC or 1 500 V DC. In special cases, a GCPC will have only one DC-port interface, which is connected to a bidirectional energy-storage device. This…

IEC 62351-9:2017 specifies cryptographic key management, namely how to generate, distribute, revoke, and handle public-key certificates and cryptographic keys to protect digital data and its communication. Included in the scope is the handling of asymmetric keys (e.g. private keys and public-key certificates), as well as symmetric keys for groups (GDOI). This document assumes that other standards…

ISO 294-1:2017 specifies the general principles to be followed when injection moulding test specimens of thermoplastic materials and gives details of mould designs for preparing two types of specimen for use in acquiring reference data, i.e. type A1 and type B1 test specimens as specified in ISO 20753, and provides a basis for establishing reproducible moulding conditions. Its purpose is to…
