ASTM C230/C230M-03

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

SCOPE
1.1 This specification coves requirements for the flow table and accessory apparatus (Note 1) used in making flow tests for consistency of mortars in tests of hydraulic cement.
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 inch-pound units or SI units shall be regarded separately as standard. The values stated are not exact equivalents; therefore, each system must be used independently of the other. 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.
