Are EPS and EPSS the same in markings on flatware?

EPS and EPSS on flatware typically refer to different types of stainless steel. EPS stands for "Electro Plated Stainless," indicating a thin layer of stainless steel over another metal, while EPSS denotes "Electro Plated Silver Stainless," which suggests a silver plating over stainless steel. Therefore, they are not the same and indicate different compositions and qualities of flatware.
