Standard Specification for Flow Table for Use in Tests of Hydraulic Cement

Designation: C230/C230M - 20 Standard Specification for Flow Table for Use in Tests of Hydraulic Cement1 1. Scope* 1.1 This specification covers requirements for the flow tableand accessory apparatus (Note 1) used in making flow tests forconsistency of mortars in tests of hydraulic cement, such as butnot limited to Test Method C1437. NonE 1—To help clarify the design of the flow table and accessoryapparatus see the drawing in Fig. 1 [Fig. 2]. This drawing is forinformational purposes only. 1.2 The values stated in either Sl units or inch-pound unitsare to be regarded separately as standard. The values stated ineach system may not be exact equivalents; therefore，eachsystem shall be used independently of the other. Combiningvalues from the two systems may result in non-conformancewith the standard. It is permissible to use an inch-pound caliperand mold with a Sl flow table or a SI caliper and mold with aninch-pound flow table. It is not permissible to mix a Sl moldwith an inch-pound caliper or an inch-pound mold with a SIcaliper. 1.3 This standard does nor purport to address all of thesafety concerns，if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use. 1.4 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of lnterrational Standards，Guides and Recom-mendations issued by the World Trade Organization TechnicalBarriers to Trade (TBT) Comnittee. 2.Referenced Documents 2.1 ASTM Standards:2 C125 Terminology Relating to Concrete and Concrete Ag-gregates
