NOTES (This section contains information of a general or explanatory nature which may be helpful, but is not mandatory). 6.1 I
36、ntended use. The insulated case is primarily for use in cold climates, for the 5-gallon water can to keep water from freezing. The case and 5-gallon water can may also be used for transporting warm food, coffee or other supplies to troops in the field. 6.2 Acquisition requirements. Acquisition docum
37、ents must specie the following: a. Title, number and date of this specification b. When a first article is required (see 3.1,4.1.1 and 6.3) c. Color selection in accordance with 3.2.1 d. Sampling plan for conformance inspection (see 4.1.2) e. Packaging requirements (see 5.1) 6.3 First article. When
38、requiring a first article inspection, contracting documents should provide specific guidance to offerors. This guidance should cover whether the first article is a first article sample, a first production item, or the number of test items. These documents should also include specific instructions re
39、garding arrangements for examinations, approval of first article test results and disposition of first articles, Pre-solicitation documents should provide Government waiver rights for samples for first article inspection to bidders offering a previously- acquired or tested product. Bidders offering
40、such products who wish to rely on such production testing must furnish evidence with the bid that prior Government approval is appropriate for the pending contract. 6.4 Conformance inspection. Affordable conformance inspection with confidence varies depending upon a number of procurement risk factor
41、s. Some of these factors include contractor past performance, government schedules and budget, product material and design maturity, manufacturing capital equipment and processes applied, the controlled uniformity of those processes, labor skills and training, and the uniformity of measuring process
42、es and techniques. During the solicitation, contracting documents should indicate those tests desired fiom table I and their designated frequency based on a risk assessment for the procurement. 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PR
