This standard specifies:

a a)  requirements for the manufacturing, alloying and testing of gold articles of 23, 22, 20, 18, 15, 14,12, 10 and 9 kt gold;

b b) requirements for findings and solders to be used in the manufacture of gold articles;

c c) methods for assaying gold, alloyed gold, solder, findings and gold articles; and

d d) requirements for marking and labelling of imported gold articles.

 
NNOTE It does not specify requirements for design of gold articles and does not apply to gold articles intended for industrial purposes such as dentistry, electronics, official coins, gold bars and other such uses.

This standard prescribes the wording of a warning notice and its presentation to the consumers in advertisements for cigarettes on television, radio, press, posters and other media of communication. It also covers the requirements for the advertising of other tobacco products. Certain types of promotional materials and advertisements are excluded (See 3.7).

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 specifies requirements for full peripheral ultrasonic shear wave testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of longitudinal imperfections according to four different acceptance levels (see table 1). This standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 9 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5. For tubes with an outside diameter-to-thickness ratio less than 5, one of the methods specified in Annex A shall be used by agreement between manufacturer and purchaser. 

  This standard specifies requirements for eddy current testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections, according to two different acceptance levels (see tables 1 and 2).  It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm. 

 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.
