This Code provides methods to measure energy and material flows to and from an ESS that arc relevant to assessment of ESS

performance. For example, some ESS may use energy Inputs From multiple external sources. Some ESS may also produceby.products, such as water, carbon dloxlde.or industrial gases, that may have cconumlcvalueordisposal costs of Interest to users of this Code.

1-2.2 Types of Systems to Which This Code Does Not AppLy

Electrical battery storage devices (lead-acid, lithium Ion, etc.) have been specifically excluded from this Code since the test

procedures for that technology have been defined in test codes promulgated by others.

1-3 UNCERTAINTY

This Code requires an uncertainty analysis in accordance with ASME PTC 19.1. The pretest uncertainty analysis Is used to develop

unit-specific test procedures that result in meeting an agreed-upon target uncertainty. Typical values of test uncertainties,

various unit configurations, and pertocmance parameters are presented in Section 3.

Test uncertainty is an estimate of the limit of error of a test result. It is the interval about a test result that contains the

true value with a given probability, or level of confidence. Test uncertainty is based on calculations using statistics.

instrumentation information, calculation procedure, and actual test data. Code tests are suitable for use whenever performance must be determined with minimum uncertainty. Code tests are meant specifically for equipment operating in an industrial setting.
