1 SCOPe International Standard IEC 1229 is applicable to rigid insulating covers for live working on a.c. installations, including those described in IEC 743. The barriers, having dielectric withstand which depends on the positioning clearance, are excluded from this standard. 1.1 Classes Six classes of covers, differing in electrical characteristics, are provided and designated as…

This International Standard specifies the following characteristics and requirements for a general-purpose, electrical-plug connector with two or three contacts plus earth, for use with solenoids: _ the electrical characteristics of the connector; _ the dimensions of the contacts; _ the means of fixing the plug to the socket; _ the sealing procedure between the plug and the socket; _ usage…

1. Scope 1.1 This standard provides dimensional and performance requirements for safety, durability and structural adequacy of freestanding components of office desk products. 1.2 Quantities and dimensions used in this standard are given in metric units imperial equivalents shown in brackets where appropriate. The metric units shall be regarded as official in the event of dispute…

HES standards address both interoperability requirements, interconnectivity requirements and plug-compatibility requirements. Devices are described as interoperable if the functionality of the higher communication layers is such that commands can be exchanged and result in meaningful action. For interconnectivity it is sufficient to specify mechanical, electrical, and functional (lower layer…

IEC 60068-2-18:2000 Provides methods of test applicable to products which, during transportation, storage or in service, may be subjected to falling drops, impacting water or immersion. The primary purpose of water tests is to verify the ability of enclosures, covers and seals to maintain components and equipment in good working order after and, when necessary, under a standardized dropfield or…

1 Scope This Standard 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 52 kV a.c., and frequencies from 15 Hz to 60 Hz. It applies only to capacitive voltage detectors used in contact with the part to be tested, as a single unit including its insulating pole as covered by CAN/ULC-D61235-00 or CAN…

CAN/CGSB-155.21 (Recommended Practices for the Provision and Use of Workwear for Protection Against Hydrocarbon Flash Fire) is not a mandatory part of CAN/CGSB-155.20 (Workwear for Protection Against Hydrocarbon Flash Fire). 1. SCOPE 1.1 These recommended practices provide guidance for the selection, use, maintenance, retirement, and understanding of the limitations of workwear for the…

1 SCOPe This International Standard is applicable to insulating hollow tubes made of synthetic materials and intended for tools and equipment for work on systems operating at voltages above 1 kV. Separate special technical standards give details of tests for fittings and attachments to these hollow tube terminal parts or complete tools.

1 SCOPE This part of IEC 61243 is applicable to two-pole voltage detectors to be used on electrical systems for nominal voltages not exceeding 1 000 V a.c. and/or 1 500 V d.c. and below 500 Hz (nominal frequencies). The detector types are classified as follows: voltage class A: up to and including 500 V a.c./750 v d.c.; voltage class B: up to and including 1 000 V a.c./1 500 V d.c.…

This National Standard of Canada is based on International Standard CEI/IEC 60855: 1985. 1. Scope This standard is applicable to insulating foam-filled tubes and solid rods made of synthetic materials and intended for tools and equipment for live work on systems operating at voltages above 1 kV. Separate special technical standards give details of tests for fittings and attachments to…
