Introduction

The report is based on GB/T 17215.911 "credibility electrical measuring equipment - Part 11. General concepts." this report focuses on the following questions.

--- Definition of complexity equipment;

--- Failure classification;

--- Through the field to return the faulty equipment for data collection;

--- By the method of sampling for data collection.

Or more sections for the collection and classification of failure data, and these data can be reliably used to assess static electricity measuring device Sex. Such as IEC 60812. 1985 as described in the failure can be classified in different ways.

For on-site static electrical measurement equipment reliability assessment, we selected a number of special classification from the current standard.
