This test method covers the determination of the time of setting of concrete, with slump greater than zero, by means of penetration resistance measurements on mortar sieved from the concrete mixture. This test method is suitable for use only when tests of the mortar fraction will provide the information required. This test method may also be applied to prepared mortars and grouts. This test method is applicable under controlled laboratory conditions, as well as under field conditions. The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
WJE laboratories are accredited by ANAB (ISO/IEC 17025) to perform testing standard ASTM C403 for Time of Setting of Concrete Mixtures by Penetration Resistance.
