Where would I look to find the ISO/IEC 17020:1998 or newer standard
Thank you for your question. We do not seem to have any information here in the library pertaining to the ISO/IEC. I would suggest that you go to the internet and look into the ISO/IEC http://www.standardsinfo.net/info/index.html and perhaps you will find the information you are looking for there.
I also suggest that you contact the Howard County Public Library to see if they have any further information. The number for the Central Branch is 410-313-7800.
I hope this helps.
