Hello Group -

In the UL IQ for Plastics database, the CTI values are given as a single
digit number, 0 thru 5. I know that the scale correlates to 100 V thru 600
V, but I forget which way it goes. Does CTI of 5 = 600 V, or is it the other
way around? Is this scale given in UL746A or IEC 60112 ?

Thanks in advance.
