This standard covers portable flexible lighting products with a maximum input voltage rating of 120volts to be used in accordance with the National Electrical Code, ANSI/NFPA 70. These products are provided with a power supply cord and are intended for outline and decorative lighting use.1.2 These requirements cover lighting products incorporating non-replaceable series and series/parallel connected lamps enclosed within a flexible polymeric tube or extrusion.1.3 These requirements also cover flexible lighting products used in light sculptures.1.4 These requirements do not cover lighting products with replaceable lamps.1.5 These requirements do not cover the temporary-use, seasonal decorative-lighting products and accessories with a maximum input voltage rating of 120 V that are covered by the Standard for Seasonal and Holiday Decorative Products, UL 588.

Requirements contained in this Standard cover controls of the light-sensitive or presence-sensitive types, or both; for indoor or outdoor service; intended for the control of indoor or outdoor loads up to maximum of 20 A and maximum 347 V; intended for installations on 50 Hz or 60 HZ systems or DC upto 60 V (for US); and DC up to 42.4 V (for Canada); and intended to be installed in accordance with the National Electrical Code (NEC), NFPA 70, the Canadian Electrical Code (CE Code) Part I, CSA C22.2 No0, and NOM 001 SEDE.

1.1 These requirements cover flat-plate photovoltaic modules and panels intended for installation on or integral with buildings, or to be freestanding (that is, not attached to buildings), in accordance with the National Electrical Code, NFPA 70, and Model Building Codes. 1.2 These requirements cover modules and panels intended for use in systems with a maximum system voltage of 1500 V or less. 1.3 These requirements also cover components intended to provide electrical connection to and mounting facilities for flat-plate photovoltaic modules and panels

This part of IEC 61730 specifies and describes the fundamental construction requirements for photovoltaic (PV) modules in order to provide safe electrical and mechanical operation. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This part of IEC 61730 pertains to the particular requirements of construction. IEC 61730-2 defines the requirements for testing. This International Standard series lays down IEC requirements of terrestrial photovoltaic modules suitable for long-term operation in open-air climates. This standard is intended to apply to all terrestrial flat plate module materials such as crystalline silicon module types as well as thin-film modules. PV modules covered by this standard are limited to a maximum DC system voltage of 1 500 V.

These requirements cover inverters, converters, charge controllers, and interconnection system equipment (ISE) intended for use in stand-alone (not grid-connected) or utility-interactive (grid-connected) power systems. Utility-interactive inverters, converters, and ISE are intended to be operated in parallel 

For utility-interactive equipment, these requirements are intended to supplement and be used in conjunction with the Standard for Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547, and the Standard for Conformance Test Procedures for Equipment Interconnecting Distributed Resources with Electric Power Systems, IEEE 1547.1.

These requirements cover AC modules that combine flat-plate photovoltaic modules and inverters to provide AC output power for stand-alone use or utility-interaction, and power systems that combine other alternative energy sources with inverters, converters, charge controllers, and interconnection system equipment (ISE), in system specific combinations.

1.1 This standard covers latching or locking type PV connectors either as a free connector (separate entity) or as a fixed connector (panel or bulkhead type) and rated 1500 V ac or dc or less. These connectors are intended for use in wiring methods detailed in Part IV of Article 690 – Solar Photovoltaic Systems of the National Electrical Code, NFPA 70.1.2 This standard is intended for single polarity PV connectors suitable for use on insulated, stranded copper type USE-2 or Photovoltaic Wire (PV Wire) rated 90°C, 105°C, 125°C, or 150°C dry; 90°C wet;600, 1000, or 2000 V..

1.1 This standard specifies physical and performance requirements, methods of testing and marking requirements for industrial safety helmets. 1.2 It also outlines the requirements that apply to helmets for general use in industry. Additional optional performance requirements are included to apply only where specifically claimed by the helmet manufacturer.

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.
