All coupons are tested for Rockwell Hardness of C 38-45; coupons having hardness outside of this range are rejected. Acceptable coupons are stamped for identification. Coupons are acid etched with 1 + 1 HCl for approximately 2 -3 minutes. The coupons are then quickly rinsed with tap water, distilled water, wiped dried and placed in chloroform.
