Two test methods are given; Method A is the Reference Test Method using the manually operated standard Vicat apparatus, while Method B permits the use of an automatic Vicat machine that has, in accordance with the qualification requirements of this method, demonstrated acceptable performance.<\/p>\n<p>1.2 The values stated in SI units are to be regarded as the standard. Values in parentheses are for information only.<\/p>\n<p>1.3 <i>This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.<\/i> See 1.4 for a specific warning statement.<\/p>\n<p>1.4 <b>Warning<\/b> Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. The use of gloves, protective clothing, and eye protection is recommended. Wash contact area with copious amounts of water after contact. Wash eyes for a minimum of 15 min. Avoid exposure of the body to clothing saturated with the liquid phase of the unhardened material. Remove contaminated clothing immediately after exposure.<\/p>\n<p>Note 1For the method for determining the time of setting by Gillmore needles, see Test Method C266.<\/p>\n<p><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>Scope <br \/> Referenced Documents <br \/> Terminology <br \/> Summary of Test Method  <\/td>\n<\/tr>\n<tr>\n<td><b>2<b><\/td>\n<td>Significance and Use <br \/> Apparatus <br \/> Reagents and Materials <br \/> Sampling <br \/> Conditioning <br \/> Preparation of Cement Paste <br \/> Calculation <br \/> Report  <\/td>\n<\/tr>\n<tr>\n<td><b>3<b><\/td>\n<td> Manual Vicat Apparatus <br \/> Procedure A <br \/> Precision and Bias <br \/>  Automatic Vicat Apparatus <br \/> Procedure  <\/td>\n<\/tr>\n<tr>\n<td><b>4<b><\/td>\n<td>Performance Requirement (Qualification) for Automatic Vicat Instrument <br \/> Requalification of a Method <br \/> Precision and Bias  <\/td>\n<\/tr>\n<tr>\n<td><b>5<b><\/td>\n<td>Keywords <br \/> A1.
