In this action of contract a verdict was returned for the defendant. The case is here on the plaintiffs exceptions.
The plaintiff Mishara Construction Company, Inc. (Mis-hara) was the general contractor under contract with the Pittsfield Housing Authority for the construction of Rose Manor, a housing project for the elderly. In September, 1966, the plaintiff negotiated with the defendant Transit-Mixed Concrete Corp. (Transit) for the supplying of ready-mixed concrete to be used on the project. An agreement was reached that Transit would supply all the concrete needed on the project at a price of $13.25 a cubic yard, with deliveries to be made at the times and in the amounts as ordered by Mishara. This agreement was evidenced by a *124 purchase order signed by the parties on September 21, 1966. That purchase order identified the Rose Manor project and indicated that delivery was to be made “[a]s required by Mishara Construction Company.” Performance under this contract was satisfactory to both parties until April, 1967. In that month a labor dispute disrupted work on the job site. Although work resumed on June 15, 1967, a picket line was maintained on the site until the completion of the project in 1969. Throughout this period, with very few exceptions, no deliveries of concrete were made by Transit notwithstanding frequent requests by Mishara. After notifying Transit of its intention, Mishara purchased the balance of its concrete requirements elsewhere. Mishara sought in damages the additional cost of concrete incurred by virtue of the higher price of the replacement product, as well as the expenses of locating an alternate source.
The plaintiffs exceptions relate to the introduction of certain evidence and the failure of the trial judge to give certain requested instructions. Requests 2 and 3 sought instructions that the requirements that a definite quantity of goods and a definite duration of performance be specified in an enforceable contract are satisfied if the contract is one which calls for deliveries as required on a particular project. Since this is a contract for the sale of goods it is governed by the Uniform Commercial Code. G. L. c. 106. “Requirements contracts” of the kind the plaintiff contends was present here are explicitly recognized as valid by the Code in G. L. c. 106, § 2-306 (l).

The Official Comment No. 2 to that section makes clear the drafters’ intention that when quantity is phrased only in terms of output or requirements the contract “is not too indefinite since it is held to mean the actual good faith output or requirements” of the buyer
*125
or seller. Such a view is consistent with the established law of Massachusetts.

Request 9 was an instruction that the contract was not terminable until Mishara had received all the concrete it required for the project. Again, although this was a correct statement of the law, we believe it was not error for the judge to refuse it. As has been shown, the specification of deliveries as needed on the project was a sufficiently definite statement of the time for performance. Therefore this was not a contract which contemplated ongoing and open-ended performance which would be terminable on reasonable notice. G. L. c. 106, § 2-309, and comment

v.

Nor was there error in the refusal to give request 13, that on the evidence the jury “must find that [the] defendant breached its contract with [the] plaintiff by failing to deliver” Mishara’s concrete requirements. The principal issue in the case was the defendant’s claimed excuse of impossibility of performance. The determination of that issue depended on facts and circumstances which were for the jury to decide. While we suppose one could develop a nice technical argument that impossibility does not nullify a breach but rather provides an excuse for it, to give the instruction requested would surely have misled the jury on the ultimate question of liability. Moreover, the failure to give it was of no detriment to the plaintiff of which it can complain.
See Howes v. Grush,
The remainder of the plaintiffs exceptions relate to the proffered defence of the impossibility of performance. Objection was made to the introduction of all evidence regarding the existence of a picket line at the job site and the difficulty which Transit did encounter or might have encountered in attempting to make deliveries through that picket line. Furthermore, Mishara requested an instruction that Transit “was required to comply with the contract *127 regardless of picket lines, strikes or labor difficulties.” 2 As a result Mishara would have completely withdrawn the question of impossibility resulting from the picket line from the jury. We are asked to decide as matter of law and without reference to individual facts and circumstances that “picket lines, strikes or labor difficulties” provide no excuse for nonperformance by way of impossibility. This is too sweeping a statement of the law and we decline to adopt it.
The excuse of impossibility in contracts for the sale of goods is controlled by the appropriate section of the Uniform Commercial Code, G. L. c. 106, § 2-615. 3 That section sets up two requirements before performance may be excused. First, the performance must have become “impracticable.” Second, the impracticability must have been caused “by the occurrence of a contingency the nonoccurrence of which was a basic assumption on which the contract was made.” This section of the Uniform Commercial Code has not yet been interpreted by this court. Therefore it is appropriate to discuss briefly the significance of these two criteria.
With respect to the requirement that performance must have been impracticable, the official Code comment to the section stresses that the reference is to “commercial im
*128
practicability” as opposed to strict impossibility. G. L. c. 106, § 2-615, comments 3-4. This is not a radical departure from the common law of contracts as interpreted by this court. Although a strict rule was originally followed denying any excuse for accident or “inevitable necessity,” e.g.,
Adams v. Nichols,
The second criterion of the excuse, that the intervening circumstance be one which the parties assumed would not occur, is also familiar to the law of Massachusetts.

With this backdrop, we consider Mishara’s contention that a labor dispute which makes performance more difficult never constitutes an excuse for nonperformance. We think it is evident that in some situations a labor dispute would not meet the requirements for impossibility discussed above. A picket line might constitute a mere inconvenience and hardly make performance “impracticable.” Likewise, in certain industries with a long record of labor difficulties, the nonoccurrence of strikes and picket
*130
lines could not fairly be said to be a basic assumption of the agreement. Certainly, in general, labor disputes cannot be considered extraordinary in the course of modern commerce. See Restatement: Contracts, § 461, illustration 7 (1932). Admitting this, however, we are still far from the proposition implicit in the plaintiffs requests. Much must depend on the facts known to the parties at the time of contracting with respect to the history of and prospects for labor difficulties during the period of performance of the contract, as well as the likely severity of the effect of such disputes on the ability to perform. From these facts it is possible to draw an inference as to whether or not the parties intended performance to be carried out even in the face of the labor difficulty. Where the probability of a labor dispute appears to be practically nil, and where the occurrence of such a dispute provides unusual difficulty, the excuse of impracticability might well be applicable. Thus in discussing the defence of impossibility, then Chief Judge Cardozo
noted an excuse
would be provided “conceivably in some circumstances by unavoidable strikes.”

Notes
“Output, Requirements and Exclusive Dealings. (1) A term which measures the quantity by the output of the seller or the requirements of the buyer means such actual output or requirements as may occur in good faith, except that no quantity unreasonably disproportionate to any stated estimate or in the absence of a stated estimate to any normal or otherwise comparable prior output or requirements may be tendered or demanded.”
Requests 16 and 17 essentially asked for instructions that in the absence of clauses in the contract to the contrary, the impossibility of performance provides no excuse. This, in effect, requires a charge that no set of circumstances will ever excuse a supplier from performing. Since we conclude in the text that request 15, to the effect that picket lines and labor disputes provide no excuse, is an incorrect statement of the law, it follows a fortiori that these requests were rightly refused.
“Excuse by Failure of Presupposed Conditions.
“Except so far as a seller may have assumed a greater obligation and subject to the preceding section on substituted performance
“(a) Delay in delivery or non-delivery in whole or in part by a seller who complies with paragraphs (b) and (c) is not a breach of his duty under a contract for sale if performance as agreed has been made impracticable by the occurrence of a contingency the non-occurrence of which was a basic assumption on which the contract was made or by compliance in good faith with any applicable foreign or domestic governmental regulation or order whether or not it later proves to be invalid.”
As has been noted, we have not had a previous occasion to address ourselves to this question in light of the Uniform Commercial Code. Therefore it is not surprising that the charge actually given by the trial judge was less than ideal on this point. But no general exception was taken to the charge given, only to the failure to give the specific instructions discussed in the opinion. Since those requests were incorrect as matter of law, there was no error in refusing them.
