Hydraulic turbines, storage pumps and pump-turbines - Model acceptance tests
IEC 60193:1999 applies to laboratory models of any type of impulse or reaction hydraulic turbine, storage pump or pump-turbine. This standard applies to models of prototype machines either with unit power greater than 5 MW or with reference diameter greater than 3 m. Full application of the procedures herein prescribed is not generally justified for machines with smaller power and size.…
Safety requirements for electrical equipment for measurement, control, and laboratory use - Part 3-0...
A technical report for use by test houses and other users. It assists them with determining and recording verification of conformity of the equipment under test with the requirements of IEC 61010-2-041 (1995). If the paper version of the report is ordered, a diskette is provided with fill-in tables for recording the test results. If the report is downloaded directly from the web, it consists of…

A technical report for use by test houses and other users. It assists them with determining and recording verification of conformity of the equipment under test with the requirements of IEC 61010-2-042 (1997). If the paper version of the report is ordered, a diskette is provided with fill-in tables for recording the test results. If the report is downloaded directly from the web, it consists of…
Presentation and specification of reliability data for electronic components
Describes the information needed for characterizing reliability of a component, and also the detailed requirements for reporting reliability data. Gives guidance to component users as to how they should specify their reliability requirements to component manufacturers. The data, derived from laboratory tests, should enable circuit and equipment designers to evaluate the reliability of circuits…
Model Code for the Field Evaluation of Electrical Equipment
1. Scope
1.1 This Model Code provides construction, marking, and test requirements for
the field evaluation of electrical/electronic equipment on behalf of
participating provinces and territories by a certification organization or an
inspection agency recognized by the regulatory authority.
1.2 This Model Code applies, but is not limited, to the following:
(a) custom-built equipment…
Petroleum products — Determination of particulate content of middle distillate fuels — Laboratory fi...
This International Standard specifies a method for the determination of the particulate content of middle distillate
fuels with a closed flash point of 38 °C or higher, determined in accordance with ISO 2719, ISO 3679 or ISO 13736.
It is not applicable to light distillate fuels (gasolines) or to aviation fuels.
A gravimetric limitation of the contamination of middle distillate fuels used in…
Ageing of thermal insulation materials — Determination of the long-term change in thermal resistance...
This International Standard specifies two laboratory test methods, based on slicing and scaling techniques, to
determine the long-term changes in the thermal resistance of closed-cell (normally 90 %) cellular plastic materials
that contain gases which, through diffusion processes, affect the properties of a foam with time.
Using standard methods for the measurement of thermal resistance, method A…
This International Standard specifies a method for the secondary calibration of acoustic emission sensors as
receivers of elastic waves at the surface of a solid medium. The International Standard is applicable to laboratory
tertiary standard sensors and acoustic emission applications sensors.
The secondary calibration yields the frequency response of a sensor to waves of a type normally…
