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.

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 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 outlines minimum requirements for performance, labelling, construction and testing of non-medical face masks. These non-medical face masks are intended to reduce the risk of general transmission of infectious agents but do not fall under the ambit of personal protective equipment (PPE).

This standard is applicable to non-medical face masks made out of paper, plastic, fabric or any other breathable materials, synthetic or natural, that are disposable or reusable. It also applies to non-medical face masks that are stitched or bonded by any other methods.

This standard does not apply to the following types of face masks:

a)     folded without stitching;

b)     medical; and

c)      elastomeric particulate respirators.

This standard does not address flame resistance, high-heat, electrical arc or related hazards.
