ASTM C230/C230M-21

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

ABSTRACT
This specification covers requirements for the flow table and accessory apparatus used in making flow tests for consistency or mortars in tests of hydraulic cement. The flow table shall consist of an integrally cast rigid iron frame and a circular rigid table top. Other details of the flow table, its mounting and lubrication are described in the specification. The conical mold for casting the flow specimen and the caliper for measuring the diameter of the mortar after it has been spread by the operation of the table are also discussed.
SCOPE
1.1 This specification covers requirements for the flow table and accessory apparatus (Note 1) used in making flow tests for consistency of mortars in tests of hydraulic cement, such as but not limited to Test Method C1437.
Note 1: To help clarify the design of the flow table and accessory apparatus see the drawing in Fig. 1 [Fig. 2]. This drawing is for informational purposes only.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. It is permissible to use an inch-pound caliper and mold with a SI flow table or a SI caliper and mold with an inch-pound flow table. It is not permissible to mix a SI mold with an inch-pound caliper or an inch-pound mold with a SI caliper.  
1.3 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.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
