This International Standard establishes a classification of fan efficiency for all jet fan types driven by motors with an electrical input power range from 5.5 kW to 155 kW (and this is likely to be in the size range 500 to 1600 mm diameter with motors rated between 5.5 kW to 150 kW from IEC 60034‑34‑1).

This standard describes a number of different procedures to classify the efficiency of a fan or to apply a minimum efficiency limit (MEL). Those procedures are described in parts 3, 4, 5 and 6. There is no method described to compare these classifications and MEL’s. Direct comparison shall not be made between the classifications and MEL’s described in parts 3, 4, 5 and 6.

This International Standard is not applicable to:

This document specifies a method for the measurement of effective focal spot dimensions above 0,1 mm of X-ray systems up to and including 1000 kV tube voltage by means of the pinhole camera method with digital evaluation. The tube voltage applied for this measurement is restricted to 200 kV for visual film evaluation.

The imaging quality and the resolution of X-ray images depend highly on the characteristics of the effective focal spot, in particular the size and the two dimensional intensity distribution as seen from the detector plane.

This test method provides instructions for determining the effective size (dimensions) of standard (macro focal spots) and mini focal spots of industrial X-ray tubes. This determination is based on the measurement of an image of a focal spot that has been radiographically recorded with a “pinhole” technique and evaluated with a digital method.

For the characterization of commercial X-ray tube types (i.e. for advertising or trade) it is advised that the specific FS values of Annex A are used.

This part of IEC 61243 is applicable to portable voltage detectors, with or without built-in power sources, to be used on electrical systems for voltages of 1 kV to 800 kV AC, and frequencies of 50 Hz and/or 60 Hz.

This part applies only to voltage detectors of capacitive type used in contact with the bare part to be tested, as a complete device including its insulating element or as a separate device, adaptable to an insulating stick which, as a separate tool, is not covered by this standard (see 4.4.1.1 for general design).

Other types of voltage detectors are not covered by this part of the standard.

NOTE: Self ranging voltage detectors (formally “multi range voltage detectors”) are not covered by this standard.

Some restrictions or formal interdictions on their use are applicable in case of switchgear of IEC 62271 series design, due to insulation coordination, on overhead line systems of electrified railways (see Annex B, instructions for use) and systems without neutral reference. For systems without neutral reference the insulating level shall be adapted to the maximum possible voltage to the earth (ground).

Products designed and manufactured according to this standard contribute to the safety of users provided they are used by persons trained for the work, in accordance with the hot stick working method and the instructions for use.

Except where otherwise specified, all the voltages defined in this standard refer to values of phase-to-phase voltages of three-phase systems. In other systems, the applicable phase-to-phase or phase-to-earth (ground) voltages should be used to determine the operating voltage.
