IEC TR 63424-1:2024 describes the methods for validating dynamic power control and (dynamic) exposure time-averaging (DPC-ETA) algorithms used in RF modem chipsets of wireless devices. The DPC-ETA implementations are exposure-based, where SAR is time-averaged according to power recorded by the RF modem. Time-averaging windows up to six minutes consistent with applicable SAR limits and regulatory…

IEC 60335-2-40:2024 deals with the safety of electric heat pumps, sanitary hot water heat pumps and air conditioners, incorporating motor-compressors as well as hydronic fan coils units, dehumidifiers (with or without motor-compressors), thermoelectric heat pumps and partial units, their maximum rated voltage being not more than 300 V for single phase appliances and 600 V for other appliances…

IEC 60794-2-20:2024 is part of a family specification covering multi-fibre optical cables for indoor use. The requirements of the sectional specification IEC 60794-2 are applicable to cables covered by this document. Annex B contains a blank detail specification and general guidance in case the cables are intended to be used in installations governed by the MICE table of ISO/IEC 11801-1. This…

IEC TS 62257-9-5:2024 provides support and strategies for institutions involved in rural electrification projects. It documents technical approaches for designing, building, testing, and maintaining off-grid renewable energy and hybrid systems with AC nominal voltage below 500 V, DC nominal voltage below 750 V and nominal power below 100 kVA. The purpose of this document is to specify laboratory…

This document provides guidance and requirements for grade classification of performance of recovered reverse osmosis (RO) membranes for water reuse systems. This standard is applicable to the spiral-wound type of recovered membranes from seawater reverse osmosis (SWRO) and brackish water reverse osmosis (BWRO) systems. This standard is to ensure consistency in the performance of recovered RO…

Scope 1.1 These requirements cover the transients test method for fire, security, and life safety equipment. These tests include supply line (ring wave surge voltage) transients, Internally induced Transients, Sequential Arc Transients, Radiated Electromagnetic Fields, Field-Wiring Transients, Surge Immunity Test (Combination Wave), Surge Current Test, and Static Discharge Test. 1.2 Tests…

IEC 60670-1:2024 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 60670-1:2024 applies to boxes, enclosures and parts of enclosures (hereafter called "boxes" and "…

IEC 60331-4:2024 specifies the test apparatus and procedure, and gives the performance requirements, including recommended flame application times and flame temperatures, for power cables of rated voltage higher than 0,6/1,0 kV up to and including 18/30 kV for maintaining circuit integrity when subject to fire and mechanical shock under specified conditions. The test method in this document is…

IEC 61188-6-3:2024 specifies the requirements for lands and land pattern on circuit boards for the mounting of components with leads by soldering based on the solder joint requirements of IEC 61191-1 and IEC 61191-3. This part of IEC 61188 specifies the requirements for soldering surfaces on circuit boards. This includes lands and land pattern for surface mounted components and also solderable…

This document describes the series of privacy, security, and safety standards to support the HES Gateway and attached devices. The purpose is to specify methods for protecting home and building systems from both internal and external threats, intrusions, or unintended observation of data and unsafe conditions that could result from network functions. Part 3 defines a set of basic and advanced…
