A transverse test bar cast in accordance with Regulation
88(a) must when placed on supports set at the
distance shown in column 2 of the following table sustain
a load applied at the centre of not less than that shown in
column 3 and must show before rupture a deflection not less
than that shown in column 4. The supports and the point of
application of the load shall be rounded to a radius of not
less than 1/8 inch.

If the diameter of a transverse test bar as cast varies
within the limits specified in Regulation 88(a) the equivalent
breaking load for the test bar of standard diameter shall
be calculated in accordance with the given factors in
Appendix F.
