Standards

This standard specifies the general labelling requirements for Electrical Equipment, Fittings and household electrical appliances and their detachable heating element(s) if any, offered for sale in Guyana. This Guyana Standard shall be applied for all Electrical Equipment, Fittings and household electrical appliance, should there be a standard for a particular product it shall be applied in conjunction with the labelling requirements of this standard.

This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.

This specification covers poly(vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.

The requirements cover television equipment intended for household and commercial use on supply circuits in accordance with the National Electrical Code, NFPA 70. 

This standards covers thermoplastic and rubber tapes for use as electrical insulation at not more than 600 V and at 80C (176 F) and lower temperatures on joints and splices in wires and cables in accordance with the National Electrical Code. It is intended that rubber tape on a joint or splice be mechanically protected by a covering such as friction tape . Thermoplastic tape is acceptable without the additional mechanical protection.

These requirements cover portable, stationary, and fixed uninterruptible power supplies (UPS) rated 600 volts or less ac or dc that are intended for installation in accordance with the National Electrical Code, NFPA 70.  During intended operation, the UPS allows the utility to deliver ac and dc power to the connected load through either the power conversion portion of the UPS or a bypass source. The power conversion portion of the UPS consists of a rectifier and an inverter.  During periods of power fluctuations, or power outage, or both, the connected load receives ac and dc power from the battery supply and power conversion portion of the UPS.

This standard describes the requirements and operational parameters for electrical appliance protectors for use with equipment at normal voltage of 110V, 120V,220V, 240V and a current of up to including 40 A.

This British Standard specifies requirements for the construction dimensions and mechanical and electrical properties of non- armoured polyvinyl chloride (PVC) insulated cables for operation at voltages up to and including 450 V a.c. to earth and 750 V a.c between conductors, intended for electric power lighting and internal wiring.
