This document provides an overview of the validation of air quality measurement methods in the standardization process. This document deals with robustness testing and interlaboratory testing as the two main steps of partial and full validation. It applies to the different inter-related elements of air quality measurement methods, covering e.g. sampling, sample preparation, storage and…

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 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 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 "…

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…

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 best practices for use case projects in terms of projects, templates and plans, with the objective to improve the consistency of content across different use case projects and enable sharing of knowledge between projects. A long-term goal is to foster interoperability between tools supporting the collection and maintenance of use cases. This document is intended for…

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…

This standard provides a comprehensive set of procedures for verifying the correct implementation of each capability claimed on a BACnet PICS including: (a) support of each claimed BACnet service, either as an initiator, executor, or both, (b) support of each claimed BACnet object-type, including both required properties and each claimed optional property, (c) support of the BACnet network layer…
