Foreword

GB/T 20819 "industrial process control systems using analog signal conditioner" is divided into two parts.

--- Part 1. Methods for performance evaluation;

--- Part 2. Inspection and routine testing.

This is Part 2 GB/T 20819 of.

This section drafted in accordance with the rules of GB/T 1.1-2009 and GB/T 20000.2-2009 given.

This Part replaces GB/T 20819.2-2007 "industrial process control systems using analog signal controllers - Part 2. Inspection and routine Test Guidelines ", this part of the GB/T 20819.2-2007 compared to the main made editorial changes.

This section uses the translation method is equivalent to using IEC 60546-2:2010 "industrial process control systems using analog signal conditioning portion of Section 2.
