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 describes exhaust emission requirements for all new domestic and commercial vehicles which have been registered in Guyana for the first time after December 31, 1997. This standard also describes exhaust emission requirements, measurement methods and measurement equipment for all vehicles, which are imported into Guyana after December 31, 1997. All imported vehicles would be required to conform to exhaust emission limits specified in the standard. Accordingly, the exhaust emission limits must be fully documented and certified by the suppliers/manufacturers, from the country of origin.

This standard provides general guidance on

 This standard lays down general requirements on penetrant flaw detectors and their functional units which are designed to reveal invisible, or poorly visible to the eye, surface discontinuities in metals and non-metals of any geometry and at any stage of manufacture.

 This standard lays down the general specifications, requirements and tests of safety devices for fuel gases and oxygen or compressed air used downstream of cylinder or pipeline outlet regulators and of pipeline outlet valves, and upstream of blowpipes for welding, cutting and allied processes. It does not specify location and combination of these devices in the gas system.  

  This standard covers graphical symbols which are placed on resistance welding equipment, e.g., indicators and operator's controls, in order to instruct the persons handling the equipment as to its use and operation. 

  This standard specifies the maximum external leakage rates, which are acceptable for equipment used for welding, cutting and allied processes.  It applies to individual components which are used in the gas supply to a blowpipe from the connecting point of the hose (outlet of the cylinder valve or connecting point to a gas supply plant).  It does not apply to gas supply plants. 

This specifies designations for filler materials for soft soldering, brazing and braze welding, on the basis of their chemical composition. For brazing and braze welding materials only, the designation includes their solidus /liquidus temperatures.  It deals only with those filler metals used in soft soldering, brazing and braze welding which do not incorporate flux, either as a covering or as an integral part of the filler material.
