Polymeric HV insulators for indoor and outdoor use - General definitions, test methods and acceptanc...
IEC 62217:2012 is applicable to polymeric insulators whose insulating body consists of one or various organic materials. Polymeric insulators covered by this standard include both solid core and hollow insulators. They are intended for use on HV overhead lines and in indoor and outdoor equipment. The object of this standard is:
- to define the common terms used for polymeric insulators;
- to…
High-voltage switchgear and controlgear - Part 105: Alternating current switch-fuse combinations for...
IEC 62271-105:2012 applies to three-pole units for public and industrial distribution systems which are functional assemblies of switches including switch-disconnectors and current-limiting fuses designed so as to be capable of
- breaking, at the rated recovery voltage, any current up to and including the rated short-circuit breaking current;
- making, at the rated voltage, circuits to which the…
Liquid crystal display devices - Part 4: Liquid crystal display modules and cells - Essential rating...
IEC 61747-4:2012 describes the essential ratings and characteristics of LCD cells and passive matrix monochrome liquid crystal display modules. It does not apply to active matrix LCD cells nor to multicolour cells. This edition includes the following significant technical changes with respect to the previous edition:
- 2.1 and 3.1 of IEC 61747-4:1998 were deleted because these items are defined…
Safety requirements for electrical equipment for measurement, control and laboratory use - Part 2-03...
IEC 61010-2-032:2012 specifies safety requirements for HAND-HELD and hand-manipulated current sensors described below. These current sensors are for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured. They may be stand-alone current sensors or accessories to other equipment or parts of…
Coaxial communication cables - Part 1-119: Electrical test methods - RF power rating
IEC 61196-1-119:2012(E) defines the requirements to determine the average power handling capability of a coaxial cable at specified frequencies at ambient temperatures.
Semiconductor devices - Mechanical and climatic test methods - Part27: Electrostatic discharge (ESD)...
IEC 60749-27:2006+A1:2012 Establishes a standard procedure for testing and classifying semiconductor devices according to their susceptibility to damage or degradation by exposure to a defined machine model (MM) electrostatic discharge (ESD). It may be used as an alternative test method to the human body model ESD test method. The objective is to provide reliable, repeatable ESD test results so…
Geometrical product specifications (GPS) — General concepts — Part 2: Basic tenets, specifications, ...
1 Scope
This part of ISO 17450 defines terms related to specifications, operators (and operations) and uncertainties used in geometrical product specifications (GPS) standards. It presents the basic tenets of the GPS philosophy while discussing the impact of uncertainty on those tenets, and examines the processes of specification and verification as they apply to GPS.
