IEC60112 Flammability Testing Equipment Determination of CTI And PTI

Standard:

IEC60112-2009 Method for the determination of the proof and the comparative tracking indices of solid insulating materials.

It specifies the method of test for the determination of the proof and comparative tracking indices of solid insulating materials on pieces taken from parts of equipment and on plaques of material using alternating voltages. Flammability Testing Equipment

Proof tracking index (PTI)

Where, in IEC standards for material or for electrical equipment specifications, or in other standards, a proof test only is required, 50 drop tests shall be made in accordance with Clause 8 but at the single voltage specified. The required number of specimens shall withstand the test period up to at least 25 s after the fiftieth drop has fallen without tracking failure, and without a persistent flame occurring.

Operation of the over-current device by air arcs does not constitute a tracking failure.

The proof voltage shall be an integer multiple of 25 V.

Comparative tracking index (CTI)

Determination of the comparative tracking index requires the determination of the maximum voltage at which five specimens withstand the test period for 50 drops without failure and whether, at a voltage of 25 V lower than the maximum 50 drop figure, the specimen withstands 1 00 drops. If this is not the case, the maximum 1 00 drop withstand voltage has to be determined.
