Can someone provide a nickel and dime definition of Comparitive Tracking Index testing. I receive requests for this info every couple of years. I have data from my laminate supplier etc. but I don't really understand the significance (if any). Also, in this day of laminate technology, assuming a quality laminate supplier is utilized and the resin matrix is not exotic, is their any reason for a customer to question or require data regarding this atribute? ################################################################ TechNet E-Mail Forum provided as a free service by IPC using LISTSERV 1.8c ################################################################ To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TechNet <your full name> To unsubscribe: SIGNOFF TechNet ################################################################ Please visit IPC web site (http://jefry.ipc.org/forum.htm) for additional information.
