Standards
1.1 These requirements cover industrial control panels intended for general industrial use, operating from a voltage of 1000 volts or less. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum.
This International Standard specifies requirements for metallic, non-metallic and composite cable ties and their associated fixing devices used for the management and support of wiring systems in electrical installations.
Cable ties and associated fixing devices may also be suitable for other applications and where so used, regard should be taken of any additional requirements.
This standard does not contain requirements that evaluate any electrical insulation properties of the cable tie or mechanical protection of the cables provided by the cable tie.
This standard does not consider the mechanical interface of a fixing device to a solid surface such as a wall or ceiling.
This standard specifies the general labelling requirements for electrical equipment, fittings and electrical appliances and their detachable heating element (s) if any, offered for sale in Guyana.
This Guyana Standard shall be applied to all electrical equipment, fittings and electrical appliances and should therefore be a standard for a particular products. It shall be applied in conjunction with the labelling requirements of this standard.
IEC 61511-2 provides guidance on the specification design , installation operation and maintenance of safety instrumented functions and related safety instrumented system as defined in IEC 61511-1. This standard has been organized so that each clause and sub clause number herein addresses the same number in IEC 61511-1 (with the exception of the annexes).
This International standard applies to the generation of electromagnetic energy from sound and television receivers for the reception of broadcast and similar transmissions and from associated equipment. The frequency covered extends from 9 kHz to 400 GHz.
This part of ISO/IEC 9314 specifies the Media access control (MAC) , the middle sublayer of the data link layer (DLL) for fiber distributed data interface (FDDI) .FDDI (ISO/IEC 9314) provides a high -bandwidth (100 Mbit/s).general - purpose interconnection among information processing systems, subsystems and peripheral equipment , using fiber optics or other transmission media. FDDI can be configured to support a sustained data transfer rate of at least 80 Mbit/s (10 Mbytes/s). FDDI provides connectivity for many nodes distributed over distances of many kilometers in extent . Certain default parameter values for FDDDI (e.g. timer settings) are calculated on the basis of up to 1000 transmission links or up to 200 km total fiber path length (typically corresponding to 5000 nodes and 100 km of dual fiber cable, respectively), however, the FDDI protocols can support much larger networks by increasing these parameter values.
This part of ISO/IEC 18026 provides an overview of different techniques of security gateways, of components and of different types of security gateway architectures, it also provides guidlines for selection and configuration of security gateways.
This part of ISO/IEC 20000 defines the requirements for a service provider to deliver managed services of an acceptable quality for its customers
This part of ISO/IEC 20000 represents an industry consensus on quality standards for IT service management processes . These service management processes deliver the best possible service to meet a customer's business needs within agreed resource levels, i.e. Service that is professional cost-effective and with risks which are understood and managed.
This part of IEC 60076 defines sound pressure and sound intensity measurement methods by which sound power levels of transformers reactors and their associated auxiliaries may be determined.
