Standards
1.1 These requirements cover the installation of lightning protection systems on all types of structures other than structures used for the production, handling, or storage of ammunition, explosives, flammable liquids or gases, and other explosive ingredients including dust.
1.2 These requirements apply to lightning protection systems that are complete and cover all parts of a structure. Partial systems are not covered by this standard.
1.3 These requirements shall not apply to adjacent structures.
1.4 Adjacent structures shall be considered separate structures.
1.5 Adjacent structures with lightning protection shall be considered part of the structure if the adjacent structure’s lightning protection system complies with this standard and is connected to the lightning protection system of the structure in accordance with Section 10.4.

.6 Walkways that are attached to a structure shall be considered part of that structure.
1.7 Free standing Walkways shall be considered an adjacent structure under the following conditions:
a) It is separated by a fire wall and conductive media that is shared by both facilities has an SPD in accordance with Section 13.
b) It is isolated by a distance of not less than six feet and conductive media that is shared by both facilities has an SPD in accordance with Section 13.
1.8 This standard does not cover lightning protection
for:
a) Electric transmission lines or open air distribution racks,
b) Outdoor substations or switch yards, and
c) Electric generators unenclosed by a building other enclosed structure.
1.9 Enclosed generators and conventional
building structures at or associated with generators or power plants,
etc. are covered.

.10 These requirements do not cover lightning protection components, which are covered by the Standard for Lightning Protection Components, UL 96.1.1 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 International Standard specifies requirements for metallic, non-metallic and composite cable ties and their associated fixing devices used for the management and support of wiring systems in electrical installations.
Cable ties and associated fixing devices may also be suitable for other applications and where so used, regard should be taken of any additional requirements.
This standard does not contain requirements that evaluate any electrical insulation properties of the cable tie or mechanical protection of the cables provided by the cable tie.
This standard does not consider the mechanical interface of a fixing device to a solid surface such as a wall or ceiling.
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.
IEC 61511-2 provides guidance on the specification design , installation operation and maintenance of safety instrumented functions and related safety instrumented system as defined in IEC 61511-1. This standard has been organized so that each clause and sub clause number herein addresses the same number in IEC 61511-1 (with the exception of the annexes).
This International standard applies to the generation of electromagnetic energy from sound and television receivers for the reception of broadcast and similar transmissions and from associated equipment. The frequency covered extends from 9 kHz to 400 GHz.
This part of IEC 60076 defines sound pressure and sound intensity measurement methods by which sound power levels of transformers reactors and their associated auxiliaries may be determined.
Part 4-41 pf IEC specifies essential requirements regarding protection against electric shock. Including basic protection (protection against direct contact) and fault protection (protection against indirect contact) of persons and livestock. It deals also with the application and co-ordination of these requirements in relation to external influences.
