Section 402.606 - 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 the buyer will take or retain them in spite of their nonconformity; or(b) Fails to make an effective rejection (s. 402.602(1) ), 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 the seller.(2) Acceptance of a part of any commercial unit is acceptance of that entire unit. When a buyer accepts goods, the seller need not prove that the goods were not defective in an action to recover the purchase price. Central Soya Co. Inc. v.
