Instructions for conducting and reporting the generally applicable and acceptable tests to determine the performance characteristics of polyphase induction motors having liquid in the magnetic gap are given. Constants in several equations and forms apply to three-phase motors only and require modifications for applications to motors having another number of phases. It is not intended that the procedures cover all possible tests or tests of a research nature. The procedures shall not be interpreted as requiring the making of any or all tests described herein in any given transaction.<\/p>\n<h4>PDF Catalog<\/h4>\n<table border=\"1px\" class=\"des-table\">\n<tr>\n<th>PDF Pages<\/th>\n<th>PDF Title<\/th>\n<\/tr>\n<tr>\n<td><b>1<b><\/td>\n<td>IEEE Std 252\u2122-2022 Front cover  <\/td>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>Title page  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>Important Notices and Disclaimers Concerning IEEE Standards Documents <br \/> Notice and Disclaimer of Liability Concertning the Use of IEEE Standards Documents <br \/> Translations  <\/td>\n<\/tr>\n<tr>\n<td><b>5<b><\/td>\n<td>Official statements <br \/> Comments on standards <br \/> Laws and regulations <br \/> Data privacy <br \/> Copyrights  <\/td>\n<\/tr>\n<tr>\n<td><b>6<b><\/td>\n<td>Photocopies <br \/> Updating of IEEE Standards documents <br \/> Errata <br \/> Patents  <\/td>\n<\/tr>\n<tr>\n<td><b>7<b><\/td>\n<td>IMPORTANT NOTICE  <\/td>\n<\/tr>\n<tr>\n<td><b>8<b><\/td>\n<td>Participants  <\/td>\n<\/tr>\n<tr>\n<td><b>9<b><\/td>\n<td>Introduction  <\/td>\n<\/tr>\n<tr>\n<td><b>10<b><\/td>\n<td>Contents  <\/td>\n<\/tr>\n<tr>\n<td><b>11<b><\/td>\n<td>1.
