Time of Setting of Hydraulic Cement by Vicat Needle

 
These test methods determine the time of setting of hydraulic cement by means of the Vicat needle. Two test methods are given: Test Method A is the Reference Test Method using the manually operated standard Vicat apparatus, while Test 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 standard. No other units of measurement are included in this standard.
