Title 11, Chapter 2, Section 606
What constitutes acceptance of goods.
(1) Acceptance of goods occurs when the buyer:
(a) After a reasonable opportunity to inspect the goods signifies
to the seller that the goods are conforming or that he will take
or retain them in spite of their nonconformity; or
(b) Fails to make an effective rejection (subsection (1) of Code Section 11-2-602), but such acceptance does not occur until the buyer has had a reasonable opportunity to inspect them; or
(c) Does any act inconsistent with the seller's ownership; but if
such act is wrongful as against the seller it is an acceptance
only if ratified by him.
(2) Acceptance of a part of any commercial unit is acceptance of
that entire unit.
