Standard Test Methods for Testing Solvent Containing Varnishes Used for Electrical Insulation

适用范围:<p><span class="italic"><span class="italic">Control</span>8212;</span>The following tests are useful for control purposes during the manufacture and use of varnishes, and for determining the uniformity of batches:</p> <p>Specific gravity,</p> <p>Viscosity,</p> <p>Flash point, and</p> <p>Nonvolatile matter by weight.</p> <p><span class="italic"><span class="italic">Performance</span>8212;</span>The following tests are useful for determining the performance of varnishes during application and use:</p> <p>Drainage,</p> <p>Time of drying,</p> <p>Build,</p> <p>Dielectric strength,</p> <p>Thermal endurance,</p> <p>Varnish compatibility,</p> <p>Salt water proofness, and</p> <p>Oil resistance.</p><p id="s00002">1.1 These test methods cover tests for solvent containing varnishes primarily intended to provide electrical, mechanical, and chemical protection for electrical equipment. These test methods include tests for control and performance as follows:</p><p id="n00001"><table summary="TABLE 1" frame="void" id="n00001" class="rules"> <tr><td align="center" valign="top">Procedure</td><td align="left" valign="top">Section</td></tr> <tr><td align="left" valign="top">Build</td><td align="left" valign="top">37-41</td></tr> <tr><td align="left" valign="top">Dielectric Strength</td><td align="left" valign="top">42-47</td></tr> <tr><td align="left" valign="top">Drainage</td><td align="left" valign="top">25-31</td></tr> <tr><td align="left" valign="top">Flash Point</td><td align="left" valign="top">17-19</td></tr> <tr><td align="left" valign="top">Nonvolatile Matter</td><td align="left" valign="top">20-24</td></tr> <tr><td align="left" valign="top">Oil Resistance</td><td align="left" valign="top">53-55</td></tr> <tr><td align="left" valign="top">Preparation of Test Specimens</td><td align="left" valign="top"> 7</td></tr> <tr><td align="left" valign="top">Specific Gravity</td><td align="left" valign="top"> 9-12</td></tr> <tr><td align="left" valign="top">Temperature Index</td><td align="left" valign="top">48-49</td></tr> <tr><td align="left" valign="top">Time of Drying</td><td align="left" valign="top">32-36</td></tr> <tr><td align="left" valign="top">Varnish Compatibility</td><td align="left" valign="top">50-52</td></tr> <tr><td align="left" valign="top">Viscosity</td><td align="left" valign="top">13-16</td></tr></table></p> <p id="s00003">1.2 Where the entire test method is included in this standard, the precision and bias are not known unless given in the stated method.</p> <p id="s00004">1.3 The values stated in SI units are to be regarded as the standard.
