Preface
This is the second edition of CSA C819, Performance of general service fluorescent lamps.
The following revisions are included in this new edition:
(a) types of lamps covered by this Standard have been clarified;
(b) references and definitions have been updated;
(c) CRI exemption has been increased to 87 or greater;
(d) efficacy and CCT levels have been revised; and
(e) a normative Annex, Uniform test method for measuring average lamp efficacy (LE), colour rendering index (CRI), and correlated colour temperature (CCT) of electric lamps, has been added.
CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of Hydro Québec, BC Hydro, Manitoba Hydro, SaskPower, Ontario Ministry of Energy, Canadian Electricity Association, Ontario Power Authority, and Conserve Nova Scotia.
This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard.
Scope
1.1
This Standard specifies performance requirements and related test procedures used to evaluate fluorescent lamps intended for general service applications.
1.2
This Standard includes performance requirements for lamp efficacy.
1.3
This Standard applies to
(a) any straight-shaped lamp, commonly referred to as 4-foot medium bipin lamps, with a medium bipin base of 1200 mm (48 in) nominal overall length and a rated wattage of 25 W or more;
(b) any U-shaped lamps, commonly referre to as 2-foot U-shape lamps, with a medium bipin base between 560 mm and 635 mm (22 and 25 in) nominal overall length and a rated wattage of 25 W ormore;
(c) any rapid-start lamps, commonly referred to as 8-foot high-output lamps, with a recessed double-contact base of 2400 mm (96 in) nominal overall length;
(d) any instant-start lamp, commonly referred to as 8-foot slimline lamps, with a single-pin base of 2400 mm (96 in) nominal overall length and a rated wattage of 52 W or more;
(e) any straight-shaped lamp, commonly referred to as 4-foot miniature bipin standard output lamps, with a miniature bipin base between 1143 mm and 1200 mm (45 and 48 in) nominal overall length and a rated wattage of 26 W or more; and
(f) any straight-shaped lamp, commonly referred to as 4-foot miniature bipin high output lamps, with a miniature bipin base between 1143 mm and 1200 mm (45 and 48 in) nominal overall length and a rated wattage of 49 W or more.
1.4
This Standard does not apply to the following:
(a) fluorescent lamps designed to promote plant growth;
(b) fluorescent lamps specifically designed for cold temperature applications;
(c) coloured fluorescent lamps;
(d) fluorescent lamps designed to be impact-resistant;
(e) reflector or aperture lamps;
(f) fluorescent lamps designed for use in reprographic equipment;
(g) fluorescent lamps designed to produce radiation primarily in the ultraviolet region of the spectrum; and
(h) lamps with a CRI of 87 or greater.
1.5
In CSA standards, shall is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; should is used to express a recommendation or that which is advised but not required; and may is used to express an option or that which is permissible within the limits of the standard.
Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.
Notes to tables and figures are considered part of the table or figure and may be written as requirements.
Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application.
1.6
The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
