Test method for calculating the energy efficiency of single-voltage external ac-dc and ac-ac power s...
1 Scope
1.1 General
This Standard specifies a test method for calculating the energy efficiency of external power supplies (EPS) across a full range of load conditions. It covers single-voltage external ac-dc and ac-ac power supplies, which provide one ac or dc output that is at a fixed voltage or user selectable through a selector switch. Note: External power supplies are designed to convert…

Information technology - Keyboard interaction model - Machine-readable keyboard description
The goal of ISO/IEC 24757:2008 is to harmonize industry practices in matters of machine-readable keyboard descriptions (PCs, PDAs, various operating systems, etc.). It further aims to facilitate the production of interoperable drivers for the user and to better assist the user by offering a more precise mapping between the physical keyboard layout and geometrical configuration, and the logical…

Information technology - Guideline for the evaluation and selection of CASE tools
Within systems and software engineering, Computer-Aided Software Engineering (CASE) tools represent a major part of the supporting technologies used to develop and maintain information technology systems. Their selection must be carried out with careful consideration of both the technical and management requirements.
ISO/IEC 14102:2008 defines both a set of processes and a structured set of CASE…

Protective clothing — Clothing to protect against heat and flame
ISO 11612:2008 specifies performance requirements for garments made from flexible materials, which are designed to protect the wearer's body, except the hands, from heat and/or flame. For protection of the wearer's head and feet, the only items of protective clothing falling within the scope of this International Standard are gaiters, hoods and overboots. However, concerning hoods,…
Metallic materials — Measurement of mechanical properties by an instrumented indentation test — Ind...
ISO/TR 29381:2008 describes methods for evaluating tensile properties of metallic materials (true stress-strain curve and derived parameters) using an instrumented indentation test.
The ranges of application of instrumented indentation tests are in line with the classification of ISO 14577-1:2002, but the range of force recommended is from 2 N to 3 kN.
ISO/TR 29381:2008 includes the following…
