SCOPE 1.1 scope. The scope of this standard is to provide standardized provisions

9、 for evaluating the quality of cloth dress gloves. 1.2 App lication. This standard will be made applicable to contracts by references in the appropriate glove specifications. if there are any inconsistencies between the requirements of the applicable specification and this standard, the specificatio

10、n will govern. 2. APPLICABLE DOCUMENTS 2.1 Government documents. 2.1.1 Specifications, standards, and handbooks. The following specifications, standards, and handbooks form a part of this document to the extent specified herein. Unless otherwise specified, the issues of these documents are those lis

11、ted in the issue of the Department of Defense Index of Specifications and Standards (DODISS) and supplement thereto, cited in the solicitation (see 6.2).

I

13、n the event of a conflict between the text of this document and the references cited herein, the text of this document takes precedence. Nothing in this document, however, supersedes applicable law and regulations unless a specified exemption has been obtained. 3. DEFINITIONS 3.1 Fabric defects. The

14、 fabric defect definitions applicable to the standard are described in FED-STD-1491. Fabric defects shall be clearly visible when examined at a distance of 3 feet. 3.2 Knots and slubs. Only knots and slubs that exceed the limits specified in the basic cloth specification and are clearly visible when

15、 examined at a distance of 3 feet shall be scored as defects in evaluating quality of glove. 1 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-STD-1612B 3.3 Quality assurance terms and procedures. Quality assurance terms and procedures, when appl

16、icable, shall be in accordance with MIL-STD-105 and MIL-STD-109. 3.4 Open seam. The seam shall be classified open when one or more stitches joining a seam are broken or runoff, or when two or more continuous skipped or runoff stitches occur. 4. GENERAL REQUIREMENTS 4.1 This standard contains the pro

17、visions for end item examination, dimensional examination, and packaging inspection for cloth dress gloves. This standard assigns to the listed defects point values of 1, 2, or 3 depending on degree of severity. The higher point values are assigned to those defects having more detrimental effect on

18、the appearance or serviceability of the item. 5. DETAILED REQUIFWENTS 5.1 End item examination. The gloves shall be examined and all defects shall be penalized as indicated in Table II of this standard. The sample size shall be based on lot size, and the acceptance value for 3 and 2 point defects an

19、d total (3, 2, and 1 point) defects shall be as specified in Table I. The sample unit shall be one glove and the selection shall be by pairs. Defects for pairing shall be classified as a single defect, The lot shall be unacceptable if: a. The point value of 3 and 2 point defects exceeds the applicab

20、le maximum acceptable point value. OR b. The point value for total (3, 2, and 1 point) defects exceeds the applicable maximum point value. 5.2 Dimensional examination. The appropriate number of gloves selected in pairs and as determined from the table below, shall be examined for conformance to the

21、dimensional requirements cited in the table of measurements of the appropriate glove specification. When a measurement deviates from a dimension and tolerance specified, the glove shall be penalized one point. The lot shall be unacceptable if the total point value exceeds the maximum acceptable poin

22、t value specified below. Each size glove present in the lot shall be represented in the sample selected for this examination. Lot size Up thru 500 Sample size Maximum Acceptable Point Values a O 51 thru 3200 13 1 3201 thru 35,000 20 2 35,001 and up 32 3 2 Provided by IHSNot for ResaleNo reproduction

An examination shall be made to determine that packaging, packing, and marking requirements are in compliance with Section 5 of the appropriate. glove specification.

24、Defects listed below shall be scored one point. The sample size for this examination shall be five shipping containers fully prepared for delivery with the exception that they need not be closed. Defects of closure listed below shall be examined on shipping containers fully prepared for delivery. Th

25、e lot shall be unacceptable if one or more points are scored for this examination. o Examine Marking (exterior and interior Elate ri al s Workmanship Content Defect Omitted, incorrect, illegible, or improper size, location, sequence, or method of application. Any component missing, damaged, or not a

26、s specified. Inadequate application of components, such as: incomplete closure of container, flaps, loose strapping, improper taping, inadequate stapling, or open and non-continuous heat sealed seams of polyethylene bag. Bulging or distorted container. Number of intermediate packages per shipping co

27、ntainer is more or less than required. Number of pairs of gloves per intermediate package is more or less than required. 1/ - - i/ For this defect, two intermediate packages shall be examined from each shipping container in the sample. 5.4 Inspection Procedures. Inspection shall be as specified in M

28、IL-STD-105, except where otherwise indicated in this document. 5.5 Initiation of inspection. Normal inspection will be used at the start of inspection unless otherwise directed by the procurement quality assurance element administrating the contract. 5.6 Continuation of inspection. Normal, tightened

29、, or reduced inspection shall continue unchanged on successive lots except where switching procedures in 5.7 require change. 5.7 Switching procedures. 5.7.1 Normal to tightened. When normal inspection is in effect, tightened inspection shall be instituted when two out of five consecutive lots have b

30、een rejected on original inspection (e.i., ignoring resubmitted lots for this procedure.

When tightened inspection

31、is in effect, normal inspection shall be reinstituted when five consecutive lots have been considered acceptable on original inspection. 5.7.3 Normal to reduced. When normal inspection is in effect, reduced inspection shall be instituted providing that all of the following conditions are satisfied:

32、a. The preceding 10 lots have been on normal inspection and none have been rejected on original inspection; and b. The total number of points for 3 and 2 point defects in the samples from the preceding 10 lots is equal to or less than sixty percent of the total maximum acceptable point values for 3

33、and 2 point defects from the preceding 10 lots; and c. The total number of points for 3, 2 and 1 point defects in the sample from the preceding 10 lots is equal to or less than seventy-five percent of the total maximum acceptable point values for 3, 2, and 1 point defects from the preceding 10 lots;

34、 and d. Production is at a steady rate; and e. Reduced inspection is considered desirable by the procurement quality assurance element administering the contract. 5.7.4 Reduced to normal.
