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.
