This document specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air which do not incorporate a flame (flashback) arrestor used downstream of manifold, cylinder and/or pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This document does not specify the location of these devices in the gas system. This document is not applicable to safety devices which incorporate a flame arrestor, covered by ISO 5175-1.
This standard applies to electric cooking and heating appliances and to electric ,motor-operated or magnetically-driven appliances for household and similar purposes, including office machines.
This standard specifies
attachment fused and unfused plugs (caps), shuttered receptacles (sockets) for
flush surface mounting. These plugs and sockets are suitable for alternating
current circuits only of voltages not exceeding 250 volts and currents not
exceeding 15 amperes. The plugs and
receptacles covered by this standard are intended for use in making readily detachable
electrical connections in non-hazardous locations between supply circuits and
portable lamps, appliances and similar equipment.
This standard specifies requirements for two grades of unleaded gasoline in Guyana for use in motor vehicles with spark-ignition internal combustion engines. It also specifies a method for determining adulteration of premium gasoline with regular gasoline.
The standards and requirements in this document are the pre-requisite conditions for the issuance of a Technical Acceptance certificate (TAC) for television broadcasting transmitters.
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.
This standard specifies requirements and dimensions for PVC insulated cables for operation at nominal voltages up to and including 1900 V to armour or earth and 3300 V between conductors.
