Potentiometers - Part 5: Sectional specification: Single-turn rotary low-power wirewound and non-wir...
This publication also bears the number QC 410300 which is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ).
Relates to single-turn low-power wirewound and non-wirewound potentiometers with a rated dissipation normally smaller than 10 W. Prescribes standard ratings and characteristics, selects from IEC 393-1 the appropriate methods of test and gives…
Laboratory glassware — Principles of design and construction of volumetric glassware
Reference temperatur, volumetric accuracy, methods of verification and construction are considered. The annexes deal with the limits of volumetric error in relation to capacity and to the diameter at the meniscus. The interrelation between standard deviation, limit of volumetric error, and line thickness is described.
Magnetic materials. Part 2: Methods of measuring of magnetic, electrical and physical properties of ...
Describes the standard 25 cm Epstein frame and associated circuitry,
to be used for determining the B-H characteristic (both for d.c. and
for sinusoidal secondary voltage), specific total losses,
permeability, and reciprocal of complex permeability. Describes also
the standard methods for determining resistivity, coefficient of
surface insulation resistance, stacking factor, and…
Characteristics of anti-scatter grids used in X-ray equipment
Deals with the definitions, determination and indication of characteristics of anti-scatter grids used in X-ray equipment in order to reduce the incidence of scattered radiation produced particularly in the body of the patient, upon the X-ray image reception area and thus to improve the contrast of the X-ray pattern. Only linear grids are considered in this standard.
Mechanical standardization of semiconductor devices - Part 3: General rules for the preparation of o...
Completes IEC 60191-3 by defining in a more satisfactory manner the mounted length and width of DIL and QUIL packages and giving recommendations for the bending of terminals of QUIL packages used for the mounting of integrated circuits. It also lists the dimensions permitting the definition of the families of packages of Form 3 and Form 4.
Electrical relays - Part 6: Measuring relays with more than one input energizing quantity
This standard specifies the general performance requirements of all electrical measuring relays and protection equipment used in the electrotechnical fields covered by the IEC. Supersedes IEC 255-6 (1978) and its first supplement 255-6 A (1980).
Potentiometers - Part 4: Sectional specification: Single-turn rotary power potentiometers - Selectio...
This publication also bears the number QC 410200 which is the specification number in the IEC Quality Assessment System for Electronic Components (IECQ).
Prescribes standard ratings and characteristics, selects from IEC 393-1 the appropriate methods of test and gives general performance requirements for this type of potentiometer. Relates only to single-turn rotary type of power potentiometers…
