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 specifies a system of designating the sizes of ladies outerwear garments, the control dimensions on which the size designation is based and the method of indicating these dimensions on the label. This standard also specifies body dimensions related to each size, as stated in Appendix A.

This standard establishes a system of designating the sizes of children’s outerwear garments. The control dimensions on which the size designation is based and the method of indicating these dimensions on the label are specified. The standard also includes body dimension tables which specify the dimensions related to each size.

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 specifies requirements for the ultrasonic testing of the weld seam of electric resistance and induction welded steel tubes for the detection of predominantly radial longitudinal imperfections, according to two different acceptance levels.

This standard specifies requirements for the ultrasonic testing of the weld seam of submerged arc-welded (longitudinally or spirally) tubes for the detection of imperfections oriented predominantly parallel to and/or at right angles to the weld seam, according to three different acceptance levels (see table 1 and table 2).  This standard covers the inspection of tubular products with outside diameter greater than or equal to 150 mm.
