2 Performance and marking requirements
2.1 General
This document does not apply to the safety requirements that are covered in the AS/NZS 60432 series or to other performance requirements that are covered in IEC 60064.
The performance criteria set out in Clauses 2.3 to 2.6 shall apply using minimum sample sizes set out in Clause 2.2.
A test report shall show conformance to this document in accordance with AS/NZS 4934.1 for each model tested. This shall contain the applicable information specified in Appendix A.
NOTE The test values are used to determine conformance to this document.
2.2 Number of samples
The minimum sample sizes required for each test in the performance criteria set out in Clauses 2.3 to 2.6 in accordance with AS/NZS 4934.1 shall be as follows:
(a) Initial efficacy: minimum sample size is 10.
(b) Minimum median life: minimum sample size is 20.
(c) Lumen maintenance: minimum sample size is 10.
(d) Maximum wattage: minimum sample size is 10.
NOTE The test values are used to determine conformance to this document.
2.3 Lamp efficacy
2.3.1 Mains voltage incandescent lamps
When tested in accordance with AS/NZS 4934.1, mains voltage incandescent lamps shall conform to an initial efficacy as follows:
Initial efficacy: Mean value shall he  I / (0.24/sqrt (L) + 0.0103)
where
L = Mean measured initial luminous flux of the lamp samples in lumens
sqrt (L) = square root of L
NOTE No level of testing tolerance may be claimed or applied to values obtained for use in the calculation of initial efficacy used for product registration.
The required duration for ageing is 100 ± 1 h unless the lamp manufacturer specifies a lesser duration. Lamps that fail prior to 100 h shall not be included in the mean and shall be replaced with another lamp.AS 4934.2 pdf download.
