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 standard specifies the requirements for new and used pneumatic passenger car tyres, along with their storage conditions. It does not apply to tyres for highway commercial vehicles.

This document specifies the general requirements and tests for safety devices for fuel gases and oxygen or compressed air which do not incorporate a flame (flashback) arrestor used downstream of manifold, cylinder and/or pipeline outlet regulators, and upstream of blowpipes for welding, cutting and allied processes. This document does not specify the location of these devices in the gas system. This document is not applicable to safety devices which incorporate a flame arrestor, covered by ISO 5175-1.

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 document specifies the general requirements for the competence, impartiality and consistent operation of laboratories. It is applicable to all organizations performing laboratory activities, regardless of the number of personnel.

Laboratory customers, regulatory authorities, organizations and schemes using peer-assessment, accreditation bodies, and others use this document in confirming or recognizing the competence of laboratories.

 This standard specifies the general requirements for a laboratory safety management system, which will enable a laboratory to formulate a policy and objectives. It takes into account legislative requirements and information about significant risks, that the laboratory can control and over which  it can be expected to have an influence, to protect its employees and others, whose health and safety may be affected by the activities of the laboratory.
