Food products — Checking the performance of moisture meters in use — Part 2: Moisture meters for oil...
ISO 7700-2:2011 specifies a method of checking the performance of moisture meters in service for measuring the moisture content of oilseeds.
It is not applicable to either cases of pattern approval or for initial calibration of moisture meters.
The results of the verification described in ISO 7700-2:2011 are used to evaluate whether to check fully or to repair the moisture meter.
High-voltage switchgear and controlgear - Part 200: AC metal-enclosed switchgear and controlgear for...
IEC 62271-200:2011 specifies requirements for prefabricated metal enclosed switchgear and controlgear for alternating current of rated voltages above 1 kV and up to and including 52 kV for indoor and outdoor installation, and for service frequencies up to and including 60 Hz. Enclosures may include fixed and removable components and may be filled with fluid (liquid or gas) to provide insulation.…
Articulated systems and flexible systems for cable guiding
IEC 62549:2011 specifies requirements and tests for systems with adaptable linear geometry for cable guiding intended for the accommodation and retention of cables and possibly other electrical equipment in electrical and/or communication systems installations. The maximum voltage of these installations is 1 000 V a.c. and 1 500 V d.c. This standard does not apply to cable trunking systems, cable…
Low-voltage switchgear and controlgear - Device profiles for networked industrial devices - Part 2: ...
IEC 61915-2:2011 specifies root device profiles as defined by IEC 61915-1 for starters and similar equipment covered by the following product standards:
- electromechanical contactors and motor-starters (IEC 60947-4-1),
- AC semiconductor motor controllers and starters (IEC 60947-4-2),
- AC semiconductor controllers and contactors for non-motor loads (IEC 60947-4-3),
- control and protective…
Oil-filled electrical equipment - Sampling of gases and analysis of free and dissolved gases - Guida...
IEC 60567:2011 deals with the techniques for sampling free gases from gas-collecting relays from power transformers. Three methods of sampling free gases are described. The techniques described take account, on the one hand, of the problems peculiar to analyses associated with acceptance testing in the factory, where gas contents of oil are generally very low and, on the other hand, of the…
Structuring of technical information and documentation
IEC 62023:2011 provides rules for applying a method of structuring technical information and documentation by using a main document (leading document) for the clustering of the information for each object. This second edition cancels and replaces the first edition of IEC 62023 published in 2000. This edition constitutes a technical revision. It includes the following substantial changes with…
Basic principles for graphical symbols for use on equipment - Part 3: Guidelines for the application...
IEC 80416-3:2002+A1:2011 provides guidelines for the application of graphical symbols for use on equipment in order to maintain visual clarity and overall consistency when such graphical symbols are applied. It stipulates the permissible extent by which a symbol original may be modified in reproduction for actual use on equipment. It bears the edition number 1.1. The technical content is…
Low-voltage switchgear and controlgear - Part 8: Control units for built-in thermal protection (PTC)...
IEC 60947-8:2003+A1:2006+A2:2011 specifies rules for control units, which perform the switching functions in response to the thermal detectors incorporated in rotating electrical machines according to IEC 60034-11, and the industrial application. It specifies rules for that type of system comprising a positive temperature coefficient (PTC) thermistor detector having particular characteristics,…
