Recessed luminaire barriers
|Publication Date:||4 November 2011|
This Standard specifies the safety requirements for barriers for recessed luminaires to provide adequate separation from combustible building elements, insulation, and/or debris to reduce the fire risk to any surrounding material and to ensure no damage to the recessed luminaire.
Barriers can be collars, covers or complete enclosures intended to ensure combustible materials do not come in contact with hot surfaces.
This Standard specifies requirements for barriers in relation to classification, construction, testing, marking and manufacturer's instructions.
This Standard applies to any barrier intended for application to an existing or new luminaire (see Clause 1.1.3).
The recessed luminaire barrier's effect on building properties such as acoustic characteristics, movement of moisture and thermal 'R' rating is excluded from the scope of this Standard.
In Australia only
This Standard applies to permanent or removable barriers that are incorporated into luminaire fittings.
NOTE: For such fittings, AS/NZS 60598.2.2 provides requirements for the luminaire.
Any luminaire incorporating a permanent or removable recessed luminaire barrier and not marked 'Do Not Cover', apart from meeting the requirements of this Standard, needs to meet the appropriate tests in AS/NZS 60598.2.2.
Recessed luminaires marked as 'Do Not Cover' are excluded from this Standard as they do not include a permanent or removable recessed luminaire barrier.
1 'Do Not Cover' luminaires are marked with the IEC symbol.
2 This does not preclude a luminaire being tested and classified as a 'single combination' barrier.
In New Zealand only
Barriers are also intended to maintain adequate separation from all material and so reduce the influence of any surrounding material on the thermal characteristics of the recessed luminaire, ensuring the environment of the luminaire is not compromised, thus ensuring no harm to the luminaire. 'Harm' is anything that could cause the luminaire to fail, shut down, reduce its output or efficiency, adversely affect its thermal or any other properties and such like.
This Standard does not apply to permanent or removable barriers that are incorporated into new luminaire fittings, as AS/NZS 60598.2.2 provides requirements for these luminaire/barrier combinations.
