IEC 61243-3:2009 is applicable to hand-held two-pole voltage detectors with its accessories (crocodile clips and detachable leads) to be used in contact with parts of electrical systems: - for a.c. voltages not exceeding 1 000 V at nominal frequencies between 16 2/3 Hz and up to 500 Hz, and/or - for d.c. voltages not exceeding 1 500 V. Voltage detectors covered by this standard are intended to…

ISO 22009:2009 describes the main magnetospheric large-scale current systems and the magnetic field in the earth's magnetosphere and provides the main requirements for a model of the magnetospheric magnetic field. Ionospheric currents are not considered in ISO 22009:2009. ISO 22009:2009 includes a worked example of the model and establishes the parameters of magnetospheric large-scale…

ISO 22966:2009 gives common requirements for the execution of concrete structures and applies to both in-situ works and construction using prefabricated concrete elements. ISO 22966:2009 requires that the execution specification state all the specific requirements relevant to the particular structure. ISO 22966:2009 is applicable to temporary as well as permanent concrete structures. Additional…

ISO 29945:2009 specifies a manual sampling method for refrigerated liquefied DME at terminals in both loading and unloading ports. ISO 29945:2009 also specifies detailed precautions to ensure safety during sampling work. However, safety measures, proposed for equipment being used for sampling, such as sampling lines and sample cylinders, are limited to general terms because they are governed…

This National Standard of Canada is applicable to electrical insulating blankets for the protection of workers from accidental contact with live or earthed electrical conductors, apparatus or circuits and avoidance of short circuits on electrical installations. Electrical insulating blankets in rolls having a width lower than 50 mm are not covered by this standard.

This National Standard of Canada covers insulating ropes that are utilized during live working procedures in contact with parts of installations operating at voltages up to and including 800 kV r.m.s. Insulating ropes for live working procedure under rain and/or d.c. conditions are not covered…

"This International Standard covers telescopic sticks and telescopic measuring sticks to be used for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and 1 500 V and above for d.c. The…

This National Standard of Canada is equivalent to International Standard CEI/IEC 61482-1-1:2009. This part of CAN/ULC-61482 specifies test methods to measure the arc thermal performance value of materials intended for use in heat- and flame-resistant clothing for workers exposed to the thermal effects of electric arcs and the function of garments using these materials. These test methods…

This National Standard of Canada is equivalent to International Standard IEC 61482-2:2009. This National Standard of Canada standard specifies requirements and test methods applicable to materials and garments for protective clothing for electrical workers against the thermal hazards of an electric arc based on relevant general properties of the textiles, tested with selected textile test…

ISO 704:2009 establishes the basic principles and methods for preparing and compiling terminologies both inside and outside the framework of standardization, and describes the links between objects, concepts, and their terminological representations. It also establishes general principles governing the formation of designations and the formulation of definitions. Full and complete understanding…
