B Product datasheets 1 or leaflets x x x c Rated life and the related lumen maintenance factor Lx e Failure rate Fxcorresponding to the rated life f Lumen maintenance category Cat A to E, see Clause In addition the following definitions are given. For compliance with EMC requirements reference is made to regional requirements. For 626612 purposes, column Aand for professional purposes, column B is applicable.
IEC System of Conformity Assessment Schemes
Lamps which are intended for retrofit purposes shall be equipped with adequate means of cooling. For that reason this standards relies on approximation methods to 626122 the expected life L50 or L70 of any self-ballasted LED lamp.
Unless otherwise specified for a specific purpose by the manufacturer or responsible vendor, lamps shall be operated in free air in a vertical base-up position for all tests including lumen maintenance tests. Comments and observations to the comments were considered at that meeting and are incorporated in the CD.
All LED lamps in the test sample must pass these post treatment criteria. L70, F50 or L50, F Tolerances are based on the CIE MacAdam ellipses as normally applied for compact fluorescent lamps and other discharge lamps. A self-ballasted LED-lamp is considered having passed the test when the following criteria have been met: See also the text under Clause 11 with regard to the indicated percentage of tested lamps of a total batch F50 or F10 that may fail the requirements of the test.
Marking according to one of both columns is required.
These performance requirements are additional to the requirements in IEC for self-ballasted LED lamps NOTE 1 safety standard When operated in a luminaire the claimed performance data can deviate from the values established via this standard. For relevant standards see Bibliography.

The actual LED behavior with regard to lumen maintenance may differ considerably per type and per manufacturer. Additionally, the following references are applicable: This oec give additional insight as to the reliability of the measured values. General requirements and tests. Recommendations for whole product testing or batch testing are under consideration.
The definition under 3. NOTE 1 LED lamps have a different end of life characteristic than conventional lamps, because they are not subject to sudden lamp failure but will typically dim over time in a gradual way.
ice Reference is made to document CIE For normative references, see IEC At the end of these tests a and b the LED lamp shall operate and remain alight for 15 min and show no physical effects of the temperature cycling such as cracks or delaminating of the label. For dated references, only the edition cited applies.
A fast initial decrease in lumen output does not automatically imply that a ic LED will not make its rated life.
All tests shall be carried out at rated frequency. Life is always published in combination with the failure rate see NOTE iev and 3. The value and the conditions are specified in this standard, or assigned by the manufacturer or responsible vendor 3.
Annex B has been reserved for a description of an improved method as compared to CIE The harmonic content is defined as the R. At the end of this time, and after cooling down to room temperature, the lamp shall remain alight for at least 15 min.

Dedicated information on the chosen percentage is to be provided by the manufacturer. Five such cycles shall be carried out. Note Method 626122 measuring the luminous flux of LED lamps is under discussion. NOTE 2 The actual luminous intensity coupled to a specific beam angle is not an element of this performance standard, but the related luminous ief from which the beam intensity and angle are originated is subject of further testing; via calculation it can be determined whether the rated luminous intensities are realistic within the beam angle specified by the manufacturer.
For undated references, the latest edition of the referenced document including any amendments applies.
Iwc may not copy or “mirror” the file or printed version of the document, or any part of it, for any other purpose without permission in writing from IEC.
Both will not be repeated here.
In the case of a voltage range, measurements shall be carried out at the mean value. Stable operation has been reached when the temperature of the LED lamp is not increasing more than 5 K per h.

Both elements are tested.
NOTE 2 The built-in electronic driver, however, may show a sudden end of life failure.
