5 Glossary
5.1 For the purpose of this Standard, the following definitions apply.
5.2 CONFORMAL COATING – A protective covering applied on a printed wiring board to increase the dielectric voltage-withstand capability between conductors and to protect against environmental conditions. A conformal coating is not suitable as electrical insulation or as an electrical enclosure without additional evaluation.
5.3 HORTICULTURAL LUMINAIRE – A horticultural luminaire identified as such and intended to emit light at wavelengths that are intended for growing flowers, vegetables, and other plants. Horticultural luminaires may also supplement general illumination within the horticultural environment.
5.4 HORTICULTURAL SYSTEM – A prefabricated chamber, cabinet, or open frame structure of which identified for the purpose outfitted with electrical infrastructure for the active optimization of plant growth. These systems may incorporate pre-installed materials and equipment which, after installation, may be concealed and may not be accessible for inspection at the final installation site. They may additionally include lighting, shutters, controls, control panels, plumbing components (such as pump motors, solenoid valves, water reservoirs), and cooling and heating components, as part of the plant growth management control horticultural system. A horticultural system may include hydroponic, aeroponic, aquaponic and other forms of irrigation methods. Passive growing structures, such as greenhouses or tent like coverings, are not considered horticultural lighting structures in the context of this Standard.
6 Organization and Application
6.1 The standard is organized as follows:
a) Part I – Horticultural luminaires
b) Part II – Horticultural Systems.
PART I – HORTICULTURAL LUMINAIRES
CONSTRUCTION
7 General
7.1 A horticultural luminaire shall be capable of being installed in accordance with U.S. and Canadian Electrical Installation Codes as noted in 1 .1 , be provided with electrical insulation and enclosure(s) suitable for the intended grow environment, and safeguard against risk of shock, risk of fire, risk of personal injury, and to safeguard persons against exposure to optical radiation hazard under normal operating conditions.
8 Mechanical Construction General requirements
8.1 8.1 .1 A horticultural luminaire shall comply with the requirements in UL 1 598 or CSA C22.2 No. 250.0, for ″Mechanical construction,″ ″Mounting means,″ ″Open holes and openings,″ ″Accessibility of supply connections,″ and, as applicable, the additional requirements in this section of the Standard.
8.2 UV protection of polymeric materials
8.2.1 A polymeric material such as an enclosure, barrier, baffle, or water shield exposed to the sun shall not degrade such that it no longer performs its intended function. Compliance shall be determined in accordance with either the UV Exposure Conditioning Test of UL 1 598 or CSA C22.2 No 250.0, or the Ultraviolet Light Exposure Test of UL 746C or CSA C22.2 No. 0.1 7.
