A. Hi Umesh. I believe "Gehont" means "honed" in German, and that "nach" means "per" or "to" (I don't know German). But you really can't proceed this way.

If you don't have this "852 008 800 4" standard from "JED-880" (which is completely unfamiliar to me), you must contact the buyer and tell them you need copies of whatever standards and specifications you are being asked to process according to if you can't find them. Best of luck.

Regards,
