This specification covers requirements for the flow table and accessory apparatus (see Note 1) used in making flow tests for consistency of mortars in tests of hydraulic cement, such as but not limited to ASTM C1437.

Note 1—To help clarify the design of the flow table and accessory apparatus, see the drawing in Figure 1 (SI Units) or Figure 2 (U.S. Customary Units). This drawing is for informational purposes only.

The values stated in either SI units or inch-pound units shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. It is permissible to use an inch-pound caliper and mold with an SI flow table or an SI caliper and mold with an inch-pound flow table. It is not permissible to mix an SI mold with an inch-pound caliper or an inch-pound mold with an SI caliper.
