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 These requirements cover photovoltaic junction boxes intended to be attached to photovoltaic modules and panels. 1.2 These requirements cover photovoltaic junction boxes intended for factory and field wiring and may include conduit openings, wiring leads, and/or photovoltaic connectors intended for interconnection of PV modules. 1.3 The products covered by these requirements are intended to be installed in accordance with the National Electrical Code, ANSI/NFPA 70.
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.

This standard establishes the minimum energy performance standards (MEPs) for refrigerating appliances and relevant test method to specify the energy label. It also specifies the energy label requirements.
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.
