Standards
This Code of Practice gives recommendations for storage of tyres, inner tubes and flaps.
This publication was last reviewed and confirmed in 2025. Therefore this version remains current.
1.1 This standard specifies:
(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) requirements for findings and solders to be used in the manufacture of gold articles;
(c) methods for assaying gold, alloyed gold, solder, findings and gold articles;
(d) non-destructive testing of gold articles by X-ray fluorescence spectroscopy (XRF); and
(e) requirements for making and labelling of imported gold articles.
NOTE 1 It does not specify requirements for design of gold articles and does not apply to gold articles intended for industrial purpose such as dentistry, electronics, official coins, gold bars and other such uses.

This Guyana Standard is a glossary which defines terms related to passenger car and commercial vehicle tyres. The standard is divided into six sections dealing respectively with general definitions, definitions related to structure, main components, tyre dimensions, service, injury and repair.
This document specifies a method for the magnetic particle testing of ferro-magnetic steel and iron castings. It also gives acceptance criteria through severity levels defined by the nature, the area and the dimensions of the discontinuities present. This document is applicable to all ferro-magnetic castings, independent of the moulding method. A steel and iron casting is considered to be ferro-magnetic if the magnetic induction is greater than 1 T
(Tesla) for a magnetic field strength of 2,4 kA/m. This document only applies to those areas of the castings specified for testing, as well as the percentage
of castings to be tested
This document specifies a method for the liquid penetrant testing of steel and iron castings.
This standard specifies physical dimensions, performance and marking requirements for new, used and retreaded pneumatic tyres for highway commercial vehicles.
This standard also includes test methods for determining conformity to the performance requirements stated.
This standard specifies physical dimensions, performance and marking requirements for pneumatic tyres for highway commercial vehicles. Test methods for determining conformity to the performance requirements are also included.
This standard shall be applied to the production and processing of raw to heat-treated liquid milk and factory milk for human consumption. Additionally, it covers the composition and labelling of fluid milk, and fluid milk products such as pasteurised, flavoured, condensed and evaporated milk. Since the sale of raw milk for direct consumption by the end-consumer is not recommended, this standard does not establish requirements for the sale of raw milk directly to the end consumer.
Additionally, it does not cover related milk products such as fermented milk products and cheeses.
