In such a diverse industry as that of rubber manu- facturing, individual plants vary considerably in their production and quality control techniques. This docu- ment has been prepared to define the limits

5、 of acceptable quality for certain rubber gloves, regarding manufacturing defects other than such generalizations as “the workmanship shall be first class“. Defects are likely o occur from many causes such as variation in the quality of the basic materials and variations in manufacturing processes a

6、nd finishing operations. Therefore, the quality generalizations used in this docu- ment must of necessity cover a considerable range which represents the best available judgement. This document is issued as a practical yardstick which inspectors will use to appraise visually the quality of all- rubb

The primary objective of this document is to present word descriptions and photographs of possible defects in rubber gloves that may be presented or inspection. In addition, it provides a training aid for in

18、spectors. 1.2 Scope, This document covers only visual defects for all-rubber gloves (except surgical) ascertained during vis-nspection. It is not applicable to coated fabric gloves, Specifically covered are surface de- fects and out of tolerance dimensions, 1.2.1 In general, this document is not int

19、ended to take the place of a particular inspection procedure aid which may be provided for inspectors to verify conformance with a particular specification. The quality requirements specified in the basic specification are governing. 2, REFERENCED DOCUMENTS 2.1 The issues of the following documents

29、ntative major and minor defects are included to aid the inspectors, All photographs are listed in order in LIST OF FIGURES and indexed in table I according to figure number, type of defect, area of defect and classification of defect. (Major or minor) surface defects that might occur during the fabr

30、ication of alI-rubber gloves. It is not feasible to obtain examples of all possible defects; further, the defects mentioned in this standard do not abrogate requirements of a particular specification, contract or order, 4.2 It should be borne in mind that this standard has included photographs of on

31、ly the most common 5. DETAIL REQUIREMENTS 5.1 Sampling, Ail gloves shall be subjected to one or more MIL-STD-105 sampling procedures, as specified by the purchaser, except where the material specification includes a sampling plan. Acceptance or rejection of the lot , sub-lot, or batch shall be on th

32、e same basis. 5.2 Inspection procedure. The following order of procedure is suggested. 5.2.1 Surface inspection. The primary purpose of this test is to check the general quality of the vul- canizate by visual inspection. Each of the sample pairs of gloves taken in accordance with 5.1 shall be subjec

33、ted to thorough surface examination, inside and out, for construction, identification marking, visual defects and workmanship. 5.2.2 Measurement of length, size, and thickness. Length, size and thickness of the gloves shall be measured as specified by the contract, order, or specification under whic

34、h the glove is purchased. If no method is specified, use ASTM-D-180. 5.3 Classification. The gloves covered by this standard are divided into four main classes as to usage; that is, electrical, acid, solvent, and general purpose, as shown in tables I and II and on figures 1 to 29, inclusive. The deg

35、ree of seriousness of a defect depends upon the protection required in service. Acid and solvent classes are combined under one heading as their service protection requirements are similar.
