Scope

These test methods determine the time of setting of hydraulic cement by means of the Vicat needle. 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. The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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. Warning??Fresh hydraulic cementitious mixtures are caustic and may cause chemical burns to skin and tissue upon prolonged exposure. The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. Note 1??For the method for determining the time of setting by Gillmore needles@ see T 154.
