1 Scope 1.1 General This Standard specifies energy efficiencies for liquid-filled distribution transformers. The total ownership cost (TOC) methodology is recommended as the means for achieving these energy efficiencies, particularly for use by electric utilities. This Standard also specifies an optimal method for non-utility users, based on a modified TOC methodology that meets the conditions…

This document specifies a test with which in situ available concentrations of inorganic substances (such as heavy metals, arsenic and phosphorus) and organic substances in soil and soil-like materials can be simulated under forced aerobic and anaerobic conditions. The toxicity can then be estimated based on these available concentrations. The test described in this document aims to measure the…
