This standard states the performance requirements for lamps, including test methods and means of confirming compliane with the requirements , whole production appraisal methds regarding a lamp manufactuer’s test record on finished products are defined. This method can be applied for certification purposes . details of a batch test procedure, which can be used to make an assessment of specific batches, are included, but it is not suitable for certification purposes. NOTES : 1 a lamp used in china having a rated wattage 15 w and rated voltage 220 v is included. 2 separate references are made to E26/24 caps used in north America and E26/25 caps used in japan . the two are
