IEC 62325-451-3-2017 电力市场的通信框架--第451-3部分：欧洲市场的传输容量配置业务流程(明确的或隐含的拍卖)和情景模型 Framework for energy market communications – Part 451-3: Transmission capacity allocation business process (explicit or implicit auction) and contextual models for European mar
This part of IEC 62325 specifies a package for the transmission capacity allocation business process through explicit or implicit auctions and the associated document contextual models, assembly models and XML schema for use within European style markets.<br />This International standard is based on the European style market contextual model (IEC 62325-351).The scheduling business process covered by this International Standard is described in Clause 5.<br />The relevant aggregate core components (ACCs) defined in IEC 62325-351 have been contextualised into aggregated business information entities (ABIEs) to satisfy the requirements of these business processes.<br />The contextualised ABIEs have been assembled into the relevant document contextual models. Related assembly models and XML schema for the exchange of transmission capacity allocation information between market participants are automatically generated from the assembled document contextual models....

IEC/IEEE 62704-4-2020 测定30mhz至6ghz无线通信设备中人体空间平均比吸收率(SAR)峰值--第4部分:用有限元法计算SAR的一般要求 Determining the peak spatial-average specific absorption rate (SAR) in the human body from wireless communication devices, 30 MHz to 6 GHz – Part 4: General requirement
This part of IEC/IEEE 62704 describes the concepts, techniques, and limitations of the finite element method (FEM) and specifies models and procedures for verification, validation and uncertainty assessment for the FEM when used for determining the peak spatial-average specific absorption rate (psSAR) in phantoms or anatomical models. It recommends and provides guidance on the modelling of wireless communication devices, and provides benchmark data for simulating the SAR in such phantoms or models.<br />This document does not recommend specific SAR limits because these are found elsewhere 1 (e.g. in IEEE Std C95.1 [1] or in the guidelines published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) [2])....
