UCC § 2-316
Exclusion or Modification of Warranties
(1) Words or conduct relevant to the creation of an express warranty and words or conduct tending to negate or limit warranty shall be construed wherever reasonable as consistent with each other; but subject to the provisions of this Article on parol or extrinsic evidence (Section 2-202) negation or limitation is inoperative to the extent that such construction is unreasonable. (2) Subject to subsection (3), to exclude or modify the implied warranty of merchantability or any part of it the language must mention merchantability and in case of a writing must be conspicuous, and to exclude or modify any implied warranty of fitness the exclusion must be by a writing and conspicuous. Language to exclude all implied warranties of fitness is sufficient if it states, for example, that “There are no warranties which extend beyond the description on the face hereof.” (3) Notwithstanding subsection (2) (a) unless the circumstances indicate otherwise, all implied warranties are excluded by expressions like “as is”, “with all faults” or other language which in common understanding calls the buyer’s attention to the exclusion of warranties and makes plain that there is no implied warranty; and (b) when the buyer before entering into the contract has examined the goods or the sample or model as fully as he desired or has refused to examine the goods there is no implied warranty with regard to defects which an examination ought in the circumstances to have revealed to him; and (c) an implied warranty can also be excluded or modified by course of dealing or course of performance or usage of trade. (4) Remedies for breach of warranty can be limited in accordance with the provisions of this Article on liquidation or limitation of damages and on contractual modification of remedy (Sections 2-718 and 2-719).
Professor's notes
Disclaimer rules differ by warranty. Express warranties (§ 2-313) cannot easily be disclaimed once made; courts read warranty language and disclaimer language together where possible. Implied warranty of merchantability (§ 2-314) requires that the disclaimer mention "merchantability" and, if written, be conspicuous. Implied warranty of fitness (§ 2-315) requires a conspicuous writing. Section 2-316(3)(a) allows "as is" or "with all faults" language to disclaim all implied warranties.
Common misunderstanding: students treat any boilerplate as effective. The UCC sets formal requirements. A non-conspicuous disclaimer fails. A disclaimer that contradicts an express affirmation may also fail under § 2-316(1).
This is chok meeting mishpat. The conspicuousness rule is formal. The reason behind it (consumer notice) is substantive. Both layers must be satisfied for the disclaimer to do its work.

UCC § 2-316. Exclusion or Modification of Warranties.
(1) Words or conduct relevant to the creation of an express warranty and words or conduct tending to negate or limit warranty shall be construed wherever reasonable as consistent with each other; but subject to the provisions of this Article on parol or extrinsic evidence (Section 2-202) negation or limitation is inoperative to the extent that such construction is unreasonable.
(2) Subject to subsection (3), to exclude or modify the implied warranty of merchantability or any part of it the language must mention merchantability and in case of a writing must be conspicuous, and to exclude or modify any implied warranty of fitness the exclusion must be by a writing and conspicuous. Language to exclude all implied warranties of fitness is sufficient if it states, for example, that “There are no warranties which extend beyond the description on the face hereof.”
(3) Notwithstanding subsection (2)
(a) unless the circumstances indicate otherwise, all implied warranties are excluded by expressions like “as is”, “with all faults” or other language which in common understanding calls the buyer’s attention to the exclusion of warranties and makes plain that there is no implied warranty; and
(b) when the buyer before entering into the contract has examined the goods or the sample or model as fully as he desired or has refused to examine the goods there is no implied warranty with regard to defects which an examination ought in the circumstances to have revealed to him; and
(c) an implied warranty can also be excluded or modified by course of dealing or course of performance or usage of trade.
(4) Remedies for breach of warranty can be limited in accordance with the provisions of this Article on liquidation or limitation of damages and on contractual modification of remedy (Sections 2-718 and 2-719).
