DEFINITION

Classification: 75/365

Step at 300 degrees C or greater after step at less than 300

degrees C using nonmetallic material which is liquid under standard conditions:

(under subclass 364) Process in which at least two distinct process steps are performed. The process step at less than 300 degrees C using a nonmetallic material which is liquid under standard conditions precedes the process step in which the temperature is 300 degrees C or greater.
