Standards

1.1 These requirements cover solar trackers intended for installation as fixed trackers which are not attached to buildings, in accordance with the National Electrical Code, NFPA 70. Trackers intended to be installed in an area where public access is anticipated shall be evaluated for all mechanical hazards as defined in this standard. Trackers intended to be installed in an area where public access is restricted by fence, secured location, etc. should be evaluated with consideration given to the mechanical hazard requirements of this standard. These requirements also cover freestanding trackers, which are by design not required to be mechanically secured in position.

1.1 This standard identifies the required information on the production and measurement tolerances of nameplate rating of flat plate photovoltaic (PV) modules. 1.2 This standard identifies five rating conditions under which the performance parameters of PV modulesshall be reported.

This International Standard specifies the minimum requirements for the design qualification and type approval of concentrator photovoltaic (CPV) modules and assemblies suitable for long-term operation in general open-air climates as defined in IEC 60721-2-1. The test sequence is partially based on that specified in IEC 61215-1 for the design qualification and type approval of flat-plate terrestrial crystalline silicon PV modules. However, some changes have been made to account for the special features of CPV receivers and modules, particularly with regard to the separation of on-site and in-lab tests, effects of tracking alignment, high current density, and rapid temperature changes, which have resulted in the formulation of some new test procedures or new requirements.

1.1 These requirements cover aluminum (ERMC-A) and stainless steel (ERMC-SS) electrical rigid metal conduit, nipples, elbows, and couplings in 12 – 155 (3/8 – 6) trade sizes for use as metal raceway for the installation of wires and cables in accordance with CSA C22.1, Canadian Electrical Code, Part 1, NOM- 001-SEDE, Standard for Electrical Installations, and NFPA 70, National Electrical Code (see Reference Item No. 1, Annex A). It is the user’s responsibility to determine the appropriate product for the application.

1.1    These requirements cover industrial control panels intended for general industrial use, operating from a voltage of 1000 volts or less. This equipment is intended for installation in ordinary locations, in accordance with the National Electrical Code, ANSI/NFPA 70, where the ambient temperature does not exceed 40°C (104°F) maximum.

This standard specifies the information to be included on labels of all pesticides, in any form, including aerosol insecticides that are destined to be applied by end-users.

This standard does not apply to pesticides:

a) which are used as human pharmaceuticals; or

b) utilised in an industrial setting, that is, active ingredients, bulk pesticide formulations destined for reformulation, repackaging or disposal or other pesticide formulation components.

This standard specifies a system of designating the sizes of clothing, the control dimensions on which the size designation is based and the method of indicating these dimensions on the label.

This standard also specifies body dimensions related to each size, as stated in Appendix A.

This standard specifies the general labelling requirements for electrical equipment, fittings and electrical appliances and their detachable heating element (s) if any, offered for sale in Guyana.

This Guyana Standard shall be applied to all electrical equipment, fittings and electrical appliances and should therefore be a standard for a particular products. It shall be applied in conjunction with the labelling requirements of this standard.
