De protegendo test de tracking test apparatu

According to IEC60112 clause 12.2,if the behaviour of the material is unknown,a screening test shall start with at least three specimens at a maximum starting voltage of 300V with a minimum of 50 drops.If the material withstands the initial test without tracking failure and without a persistent flame,always using three specimens,increase the test voltage by 100V steps until a tracking failure or a persistent flame occurs.Then reduce the test voltage by 50v, et tandem auget aut redigendum in test intentione a 25v ad identify maximam test intentione ad determinationem de comparative tracking index.if de materia deficit in initial Test in eodem itinere ratio ad Tres specimens.

Hoc procedure necesse est quod aliqui materiae potest sustinere excelsum test voltages, sed deficit in inferioribus test voltages.

Zlt tracking test apparatu, in test intentione potest esse adaequatum, est princeps qualitas tracking test apparatu.
