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…
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,…
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…
Rubber, raw — Determination of volatile-matter content — Part 1: Hot-mill method and oven method
ISO 248-1:2011 specifies two methods for the determination of volatile-matter content in raw rubbers by using a hot mill or an oven.
The methods are applicable to the determination of the volatile-matter content in the "R" group of rubbers listed in ISO 1629. These are rubbers having an unsaturated carbon chain, for example natural rubber and synthetic rubbers derived at least partly…
0 Introduction
0.1
This harmonized Standard was developed in response to an industry request for a Standard for evaluation
of plastic plumbing fixtures that would be acceptable for use in both Canada and the United States.
Standards for plumbing fixtures made of other materials are also available or under development.
0.2
Harmonization activities for plastic plumbing fixtures Standards were…
Iron ores — Determination of the moisture content of a lot
This International Standard specifies a method for the determination of the moisture content of a lot of iron ore.
This method is applicable to all iron ores, whether natural or processed.
Medical electrical equipment - Part 2-31: Particular requirements for the basic safety and essential...
IEC 60601-2-31:2008+A1:2011 consists of the second edition (2008) and its amendment 1 (2011). The technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. IEC 60601-2-31:2008 applies to the basic safety and essential performance of external pacemakers powered by an internal electrical power source. The minimum safety requirements…
Information technology — Document Schema Definition Languages (DSDL) — Part 5: Extensible Datatypes
ISO/IEC 19757-5:2011 specifies an XML language that allows users to create and extend datatype libraries for their own purposes. The datatype definitions in these libraries can be used by XML validators and other tools to validate content and make comparisons between values.
