ITC India one of the best Thermal  Testing Laboratory in India, Mumbai, Chennai, Ahmedabad, New Delhi, Pune, Kolkata, Bangalore, Hyderabad, Surat, Visakhapatnam.
ITCIndia “Institute of Testing and Certification India Pvt. Ltd” are a leading testing lab having a NABL accreditation under ELECTRICAL, ELECTRONICS and PHOTOMETRY testing with certificate no. T-3509T-3570 and T-1811. ITCIndia Lab is following the procedure as required by International Standard IEC 17025 and is already certified for ISO/IEC 17025.
Thermal test is one of the important tests while testing LED luminaries, so we would like to have its basic knowledge.
Thermal test is performed for normal and abnormal conditions. We will peep inside both the conditions respectively.
The motive of thermal test is that the Lamp, part of the luminary, supply wiring, mounting surface should not attain the temperature which can cause injury. The parts like handles should not be too hot to be touched. Same scenario is for the track mounted luminaries are there. Track mounted Luminaries are tested as per clause 12.4.1. Draught proof chamber is specially designed for this particular test. While performing the test, the through wiring and the looping in wiring shall be loaded to the maximum value allowed by the size of the wire, or at a value prescribed by the manufacturer in the installation instructions.
After the test, none of the temperature shall exceed the values given in table 12.1 & 12.2 of IEC 60598-1.
While performing the thermal test in abnormal condition, luminaries are tested in abnormal conditions. The temperature shall not exceed as mentioned in table 12.3, 12.4, and 12.5. If the luminary possesses motor, the test is performed in most critical condition.
Clause 12.6 is applied to the luminary classified for mounting on normally flammable surfaces with a control gear. Clause 12.7 is thermal test in regard to fault conditions in lamp control gear or electronics devices incorporated in thermoplastics luminaries.


Temperature Measurement Data as per client specification

The sample was operated until constant temperatures were obtained. A temperature was considered
constant if the sample was operating for at least three hours and upon three successive readings - taken at
15 minute intervals - were within one degree and were not rising.
Thermocouples were attached at locations described in the results by means of cement made of water
