IEC 61672-3:2013 describes procedures for periodic testing of time-weighting, integrating-averaging, and integrating sound level meters that were designed to conform to the class 1 or class 2 specifications of the second edition of IEC 61672-1. The aim of the standard is to ensure that periodic testing is performed in a consistent manner by all laboratories. The purpose of periodic testing is to…

ISO 28258:2013 describes how to digitally exchange soil-related data. It aims to facilitate the exchange of valid, clearly described and specified soil-related data between individuals and organizations via digital systems, and enables any soil data producer, holder or user to find and transfer data in an unambiguous way. It contains definitions of features, several parameter specifications and…

IEC/TR 62799:2013(E), which is a technical report, provides background information for users of IEC 62359 to understand the relative merits of several of the potential replacements for the thermal index as described in IEC 60601-2-37 and IEC 62359. The report discusses parameters related to thermal aspects of diagnostic ultrasonic fields; and methods for the determination of an exposure parameter…

IEC 62270:2013 addresses the application, design concepts, and implementation of computer-based control systems for hydroelectric plant automation. It addresses functional capabilities, performance requirements, interface requirements, hardware considerations, and operator training. It includes recommendations for system testing and acceptance. The electrical protective system (generator and step…

ISO 14222:2013 specifies the structure of Earth's atmosphere above 120 km, provides accepted empirical models that can specify the details of the atmosphere, and uses annexes to describe the details of those models. Its purpose is to create a standard method for specifying Earth atmosphere properties (densities, etc.) in the low Earth orbit regime for space systems and materials users.

IEC 60794-1-2:2013 applies to optical fibre cables for use with telecommunication equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. The object of this standard is to provide the end user with a cross reference table between the second edition of IEC 60794-1-2:2003 and the five new separate parts into which is…

IEC 62567:2013 provides test procedures based on the documents mentioned in the introduction and devoted to minimize the causes of discrepancy between test results, taking into consideration the large experience accumulated in the last 30 years by numerous test engineers and available in literature, including a CIGRE Technical Brochure specifically referring to this standard (see Bibliography).…

ISO 17091:2013 specifies a method for the determination of the time-weighted average mass concentration of lithium hydroxide (LiOH), sodium hydroxide (NaOH), potassium hydroxide (KOH), and calcium dihydroxide [Ca(OH)2] in workplace air by collection of the particulate hydroxides on a filter and analysis of the corresponding cations using ion chromatography. For aerosol sampling, the method is…
