Standards

This standard outlines a code of safety for chemical laboratories.

This Code of Practice specifies managerial requirements necessary to ensure the efficient running of any restaurant establishment which seeks to ensure quality in the sight of its customers. With the application of this standard the following is expected: (a) that management of a restaurant shall be made aware of their responsibilities with regard to efficient practices in the restaurant service; (b) that customer satisfaction shall be made the ultimate goal in such an establishment; (c) high productivity for the restaurant service; and (d) that the service shall be made more competitive at local and international levels. This standard does not apply to institutional food services, such as school feeding programmed; and to food vans or vendors, in which food is sold from a vehicle or carts on the road side.

This standard specifies requirements for the information to be provided on labels of protective helmets for road users, offered for sale in Guyana. It applies to protective helmets for use by pedal cyclists and motorcyclists. It does not apply to protective helmets for use in open motorized vehicles (boats, All Terrain Vehicles (ATV) non-motorised sports, automotive racing, karting, competitive skiing and equestrian activities.

This standard was confirmed in 2019, so this version remains current. 

This standard describes exhaust emission requirements for all new domestic and commercial vehicles which have been registered in Guyana for the first time after December 31, 1997. This standard also describes exhaust emission requirements, measurement methods and measurement equipment for all vehicles, which are imported into Guyana after December 31, 1997. All imported vehicles would be required to conform to exhaust emission limits specified in the standard. Accordingly, the exhaust emission limits must be fully documented and certified by the suppliers/manufacturers, from the country of origin.

This specification covers poly(vinyl chloride) (PVC) pipe made in Schedule 40, 80, and 120 sizes and pressure-rated for water (see Appendix X1). 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.

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.

This standard provides general guidance on

 This standard lays down general requirements on penetrant flaw detectors and their functional units which are designed to reveal invisible, or poorly visible to the eye, surface discontinuities in metals and non-metals of any geometry and at any stage of manufacture.

This standard specifies requirements for full peripheral ultrasonic shear wave testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of longitudinal imperfections according to four different acceptance levels (see table 1). This standard is applicable to the inspection of tubes with an outside diameter greater than or equal to 9 mm, and with an outside diameter-to-thickness ratio greater than or equal to 5. For tubes with an outside diameter-to-thickness ratio less than 5, one of the methods specified in Annex A shall be used by agreement between manufacturer and purchaser. 

  This standard specifies requirements for eddy current testing of seamless and welded tubes for pressure purposes, with the exception of submerged arc-welded (SAW) tubes, for the detection of imperfections, according to two different acceptance levels (see tables 1 and 2).  It is applicable to the inspection of tubes with an outside diameter greater than or equal to 4 mm.
