Scope

This is for measuring energy consumption under operating modes including startup and shutdown, and the operating modes and operating patterns can be defined by the manufacturer.  The JIS specifies operating patterns incorporating 11 operating modes including rated operation and startup/shutdown, allowing different systems evaluated under the same conditions.  Manufacturers are able to provide performance data on their catalogues backed up by the standard (JIS 8851 can be referenced).  The measuring method in the standard is based on that in JEM 1490.
