Introduction

This section contains GB/T 17215 series of standards related to electrical measuring devices credibility part of the problem. Its main purpose is to provide a About a reliability analysis and prediction methods overview, select and standardize the measuring device is used to calculate the predicted failure rate of component count.

When the failure rate of the basic parameters of the forecast to know if the behavior of the instrument also know that the maintenance operator, the metering function metering end users Availability of energy can determine it.

3 Terms and Definitions

The following terms and definitions apply to this section.

For ease of use, the following list is repeated in GB/T 2900.13-2008 some terms and definitions.

Note. This is only a list of GB/T 17215.911 but not included with this topic-related terms.

Accelerated test to shorten the observation period required for product stress response to stress response or enlarge the given time period, is applied over the reference conditions specified in the the stress level of a test.

NOTE. For the validity of the results of accelerated tests do not change the basic failure modes and failure mechanisms, or primary and secondary relative relationship between them.
