This part of IEC 61557 specifies the requirements applicable to equipment for measuring the resistance of earth conductors, protective earth conductors and conductors for equipotential bonding, including their connections and terminals, with an indication of the measured value or indication of limits. This second edition cancels and replaces the first edition published in 1997. This edition…

This standard applies to the emission (radiated and conducted) of radiofrequency disturbances from: - all lighting equipment with a primary function of generating and/or distributing light intended for illumination purposes, and intended either for connection to the low voltage electricity supply or for battery operation; - the lighting part of multi-function equipment where one of the primary…

ISO/TS 13399-50:2007 specifies a reference dictionary for reference systems and common concepts for cutting tools, together with their descriptive properties and domains of values. The reference dictionary contains definitions and identifications of the classes of reference systems and common concepts for cutting tools, with an associated classification scheme, definitions and identifications of…

ISO/TS 13399-60:2007 specifies a reference dictionary for connection systems for cutting tools, together with their descriptive properties and domains of values. The reference dictionary contains definitions and identifications of the classes of connection systems for cutting tools, with an associated classification scheme, definitions and identifications of the data element types that represent…

ISO 13399-3:2007 specifies a reference dictionary for tool items, together with their descriptive properties and domains of values. It specifies a reference dictionary that contains definitions and identifications of the classes of tool items and their features, with an associated classification scheme, definitions and identifications of the data element types that represent the properties of…

ISO/TS 13399-4:2007 specifies a reference dictionary for adaptive items, together with their descriptive properties and domains of values. The reference dictionary contains definitions and identifications of the classes of adaptive items, with an associated classification scheme, definitions and identifications of the data element types that represent the properties of adaptive items, and…

1.1 Scope and object This standard applies, when required by the relevant product standard, to switchgear and controlgear hereinafter referred to as "equipment" and intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. It does not apply to low-voltage switchgear and controlgear assemblies which are dealt with in IEC 60439. NOTE…

1 Scope and object This part of IEC 60947 applies to the types of equipment listed in 1.1 and 1.2 whose main contacts are intended to be connected to circuits the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c. Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection (…

This Standard sets forth minimum requirements for the determination of the acceptability of pipe joint compounds and tapes for piping systems intended for the containment of alcohol, alcohol fuel blends natural gas and methane, oxygen, petroleum distillates, propane and butane, steam, and water (potable and non-potable).Unless otherwise specified, products meeting this Standard are considered…
