Scope

This Standard specifies a method for the determination of the modulus of rupture of
refractory products at ambient temperature, under conditions of a constant rate of
increase of stress.
The method relates primarily to shaped and fired refractories. If it is to be applied to
chemically bonded or tar-bonded bricks, they will usually require some form of
preliminary heat treatment. This preliminary treatment, the details of which are outside
the scope of this Standard, is a matter of agreement between the interested parties
and is described in the test report.

Summary	This standard specifies the rate at room temperature at a constant applied stress test methods-Determination of flexural strength of refractories. This method is applicable to amorphous and monolithic refractories. If for chemical bonding or binding bricks tar, these products are to some form of pre-heat treatment. Specific provisions of this pre-heat treatment is beyond the scope of this standard, subject to the agreement the parties concerned, and noted in the test report.
