Superconductivity - Part 4: Residual resistance ratio measurement - Residual resistance ratio of Nb-...
IEC 61788-4:2011 covers a test method for the determination of the residual resistance ratio (RRR) of composite superconductors comprised of Nb-Ti filaments and Cu, Cu-Ni or Cu/Cu-Ni matrix. This method is intended for use with superconductors that have a monolithic structure with rectangular or round cross-section, RRR less than 350, and cross-sectional area less than 3 mm2. All measurements are…

LIVE WORKING – MINIMUM REQUIREMENTS FOR THE UTILIZATION OF TOOLS, DEVICES AND EQUIPMENT
1 Scope
This International Standard gives the minimum requirements relative to specification,
manufacture, selection, application and maintenance of tools, devices and equipment for live
working.
It provides the type of information which is useful to skilled persons in order to make the use
of tools, devices and equipment safer.
This type of information includes:
• the characteristics of tools,…
IEC 60238:2004+A1:2008+A2:2011 applies to lampholders with Edison thread E14, E27 and E40, designed for connection to the supply of lamps and semi-luminaires* only. It also applies to switched-lampholders for use in a.c. circuits only, where the working voltage does not exceed 250 V r.m.s. The technical content is therefore identical to the base edition and its amendments and has been prepared…
Determination of RF field strength and SAR in the vicinity of radiocommunication base stations for t...
IEC 62232:2011 addresses the evaluation of RF field strength or specific absorption rate levels in the vicinity of non-broadcast RF radiocommunication sources (i.e. RBS) intentionally radiating in the frequency range 300 MHz to 6 GHz according to the scope (see Clause 1). It does not address the evaluation of current density which exposure guidelines often do not consider to be relevant when…
Language resource management — Persistent identification and sustainable access (PISA)
ISO 24619:2011 specifies requirements for the persistent identifier (PID) framework and for using PIDs as references and citations of language resources in documents as well as in language resources themselves. In this context, examples of language resources include such works as digital dictionaries, language-purposed terminological resources, machine-translation lexica, annotated multimedia/…
Electrical installations in ships - Part 509: Operation of electrical installations
IEC 60092-509:2011(E) is applicable to all operation of and work activity on electrical generation, conversion and distribution systems and electrical equipment in ships, including all a.c and d.c. voltages. This standard sets out the requirements for the safe operation of work and activity on, with, or near electrical installations. These requirements apply to operational, working and…

1 Scope
1.1
This Standard specifies examination and testing requirements that apply to the work of any organization
participating in the construction, fabrication, or installation of parts or components of concrete
containment structures for nuclear power plants that are designated as class containment.
1.2
This Standard specifies personnel qualification requirements for work pertaining…
1 Scope
1.1 Purpose
This Standard establishes minimum requirements for electrical work and electrical equipment operating,
or intended to operate, in mines.
Note: Users should be aware that federal, provincial, and territorial legislation can impose additional requirements.
1.2 Application
This Standard is intended to be used with the requirements of the Canadian Electrical Code, Part I, or…
ISO/IEC 24775:2011(E) defines an interface for the secure, extensible,
and interoperable management of a distributed and heterogeneous storage system.
This interface uses an object-oriented, XML-based, messagingbased
protocol designed to support the specific requirements of managing devices and
subsystems in this storage environment. Using this protocol, this International
Standard describes the…
