In trying to get some EPDM components NSF certified. In the process I have been asked for the "Manufacturing Trade Designation Number" for the materials. The materials are E7302, 85 EPDM 282 and E7311. My questions are below. Can someone help me?

1. What is a Manufacturing Trade Designation Number?
2. Is it also refered to as the Material Trade Designation Number?
3. What is a Material Code and is it the same as the above?
