Standards
The purpose of these abbreviations is to provide uniform contractions of terms relating to plastics. Abbreviated terminology has evolved through widespread common usage. This compilation of abbreviated nomenclature has been prepared to avoid the occurrence of ore than one abbreviation for a given plastics term, and double meanings for particular abbreviations.
This specification covers poly (vinyl chloride) (PVC) pipe made in standard thermoplastic pipe dimension ratios and pressure rated for water (see Appendix). Included are criteria for classifying PVC plastic pipe materials and PVC plastic pipe, a system of nomenclature for PVC plastic pipe, and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening, and extrusion quality. Methods of marking are also given.
The products covered by this specification are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, some manufacturers do not allow pneumatic testing of their products. Consult with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing.

This specification covers chlorinated poly(vinyl chloride) (CPVC) pipes made in standard thermoplastic pipe dimension ratios and pressure rated for water. (See Appendix). Included are criteria for classifying CPVC plastic pipe materials and CPVC plastic pipe, and requirements and test methods for materials, workmanship, dimension, sustained pressure, burst pressure, flattening, and extursion quality. Methods of marking are also given.
This standard describes the properties of mercury the nature of hazards associated with it and essential information on its storage, handling packing , labelling disposal of waste and personal preventive measures.
This standard sets out guidelines parameters which will be used to monitor the effluent quality for different types of industries operating in Guyana. This standard does not apply to industrial operations of mining, forestry operations and agricultural infiltration, seepage and run-off. This standard is expected to operate under the Environmental Protection Agency (EPA) regulations on Water Quality Management
