Revision of C140/C140M-23 Standard Test Methods for Sampling and Testing Concrete Masonry Units and Related Units


The Modulus of Rupture Test Apparatus is illustrated in Fig. A8.3 in Annex A8, Test Procedures for Segmental Concrete Paving Slabs. The current figure is imprecise and difficult to understand. This ballot item proposes to add a new Fig. A8.3 that is cleaner and clearer. The new figure includes a parts list that directs the user to the subsection of A8.4 that has the requirements for each part. In addition to the new figure, a new Note A8.2 is being added to clarify the requirement and possible options for leveling the rollers as well as to suggest the use of option C Channel stock to stabilize the test apparatus.
