Standards

This standard outlines a code of safety for chemical laboratories.

This standard specifies requirements for the labelling of household chemicals sold in Guyana, whether locally made or imported, and gives a series of warning labels corresponding to the designated classes of dangerous goods as detailed in Appendix A. This standard shall be read in conjunction with GYS 9-1 :1994, “Specification for labelling of commodities - Part 1: General principles”.

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 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 performance requirements for hollow load-bearing concrete masonry units made from Portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) normal weight; (b) medium weight; and (c) lightweight.

This standard specifies requirements for hollow non-load-bearing concrete masonry units made from portland cement, water and mineral aggregates with or without the inclusion of other materials. It covers three weight classifications of the concrete masonry units: (a) Normal weight; (b) Medium weight; and (c) Light weight. It also covers the sampling and testing of hollow non-load-bearing concrete masonry units for compressive strength, absorption, weight, moisture content and dimensions. It does not cover blocks intended solely for decorative purposes.

This standard specifies physical and active ingredient and requirements and methods of test for mosquito coils.

This standard specifies the method for evaluation of the biological efficacy of mosquito coils by the use of glass chamber method. This method provides a satisfactory means of determining the relative efficacy of mosquito coils.

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.
