684 SPECIFICATIONS :FOR YELLOW BRASS SAND CASTINGS
(c) In the case of castings where, in the opinion of the inspector,
it is impracticable to attach a test coupon to the casting, bars shall
be cast separately in sand. At least one test bar shall be poured
from each melt or heat of metal, or such groups of melts or heats as
the purchaser n1ay specify, but in no case shall a lot consist of more
than 1000 lb. of castings. The bars shall be cast from the first metal
poured from the heat and the inspector shall witness the pouring of
the test mold. ·
(d) If any test specimen shows defective machining or reveals
casting defects, it may be discarded and replaced by another specimen
selected by the inspector. If additional test coupons are not available,
