Measurement of smoke density of cables burning under defined conditions - Part 1: Test apparatus
IEC 61034-1:2005+A1:2013+A2:2019 provides details of the test apparatus to be used for measuring smoke emission when electric or optical fibre cables are burnt under defined conditions, for example, a few cables burnt horizontally. The light transmittance (lt) under flaming combustion and smouldering conditions can be used as a means of comparing different cables or complying with specific…
Measurement of smoke density of cables burning under defined conditions - Part 2: Test procedure and...
IEC 61034-2:2005+A1:2013+A2:2019 provides details of the test procedure to be employed for the measurement of the density of smoke emitted from cables burning under defined conditions. It describes the means of preparing and assembling cables for test, the method of burning the cables, and gives recommended requirements for evaluating test results. The principal changes with respect to the…
Reliability testing - Compliance test plans for success ratio
IEC 61123:2019 is intended to define a procedure to verify if a reliability of an item/system complies with the stated requirements. The requirement is assumed to be specified as the percentage of success (success ratio) or the percentage of failures (failure ratio). This document can be used where a number of items are tested (number of trials performed) and classified as passed or failed. It…
Information technology - Power efficiency measurement specification for data center storage
This document describes a standardized method to assess the energy efficiency of commercial storage products in both active and idle states of operation. A taxonomy is defined that classifies storage products in terms of operational profiles and supported features. Test definition and execution rules for measuring the power efficiency of each taxonomy category are described; these include test…

This document specifies steering system tests and performance criteria for evaluating the steering capability of wheeled, ride-on earth-moving machinery as defined in ISO 6165:2012. Wheeled machines include machines equipped with wheels, one or more drums or crawler wheel assemblies.
This document deals with the following significant hazards, hazardous situations or hazardous events relevant to…
Information technology - Process assessment - Process measurement framework for assessment of proces...
This document defines a process measurement framework that supports the assessment of process capability, in accordance with the requirements of ISO/IEC 33003. The process measurement framework provides a schema that can be used to construct a process assessment model conformant with ISO/IEC 33004 which can be used in the performance of assessment of process capability according to the…
Sustainable cities and communities — Descriptive framework for cities and communities
This document specifies a descriptive framework for a city including an associated foundational ontology of the anatomical structure of a city or community. The descriptive framework is intended to have the following qualities:
— timeless, i.e. compatible with any human settlement at any time in history;
— acultural, i.e. valid for any culture and any type of city;
— scalable, i.e.…
