Laboratory accreditation examination

【The feature of our Laboratory accreditation examination services 】

●We acquired ISO/IEC17025 authorization for the first time in the plating industry in Japan.
●An ISO/IEC17025 authorization item is all the 13 items (as of 2013).
●The authorization range is conducting analysis broad from RoHS analysis of a plating membrane to plating film thickness, an evaluation test, and drainage analysis.
●We can take out an analysis result as a formal report with an authorization mark.


To differentiation with the other company! To international appeal!
Please utilize an authorization mark!
