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 Code of Practice establishes the recommendations for the hygienic preparation of packaged natural coconut water  inclusive of harvesting, processing, packaging, storing, transporting and distributing.

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 specification covers rigid PVC and CPVC compounds intended for general purpose use in extruded or molded form, including piping applications involving special chemical and acid resistance or heat resistance, composed of poly(vinyl chloride), chlorinated poly(vinyl chloride), or vinyl chloride copolymers containing at least 80 % vinyl chloride, and the necessary compounding ingredients. The compounding ingredients may consist of lubricants, stabilizers, non-poly(vinyl chloride) resin modifiers, pigments, and inorganic fillers. Note 1—Selection of specific compounds for particular end uses or applications requires consideration of other characteristics such as thermal properties, optical properties, weather resistance, etc. Specific requirements and test methods for these properties shall be by mutual agreement between the purchaser and the seller.

This specification covers joints for plastic pipe systems intended for drain, and gravity sewerage pipe at internal or external pressures less than 25-ft head using flexible watertight elastomeric seals. this specification is intended to cover test requirements, test methods, and acceptable materials. the test methods described for the joints are not intended to be routine quality control tests but to be reliability or performance requirements.

This test method describes two essentially equivalent procedures: one for obtaining a long-term hydrostatic strength category based on stress, referred to herein as the hydrostatic design basis (HDB); and the other for obtaining a long-term hydrostatic strength category based on pressure, referred to herein as the pressure design basis (PDB). The HDB is based on the material's long-term hydrostatic strength (LTHS),and the PDB is based on the product's long-term hydrostatic pressure-strength (LTHSP).

Adopted ASTM D 1598-02. This test method covers the determination of the time-to-failure of both thermoplastic and reinforced thermosetting/

resin pipe under constant internal pressure.     

This test method covers the determination of the resistance of either thermoplastic or reinforced thermosetting resin pipe, tubing, or fittings to hydraulic pressure in a short time period. Procedure A is used to determine burst pressure of a specimen if the mode of failure is to be determined. Procedure B is used to determine that a specimen compiles with a minimum burst requirement.
