6、replaces the following publications on the same subject: ORD-SIP-3327, 1 April 1954, and ORDSIP-3327, Amendment 1, 1 November 1955. This publication serves to create a military standard which evaluates and illustrates a practical majority of defects assembled as a result of extensive surveys coverin
7、g box, can and small arms ammunition manufacturing facilities. The format used retains most of the features of the formats of the publications it replaces because experience has proued that the numbering of illustrations to conform to the numbering of visual defects in the applicable detail specific

This standard provides proce- dures for determining and evaluating defects in steel bones and terne plate cans used in the packaging of small-arms ammunition a
11、nd the standard shall be used as a supplement to pertinent specifications. 1.2 Purpose. The purpose of this standard is to- a. Create standardization of defect nomen- clature and establish the limits of defectiveness for steel box and terne plate can acceptance inspection at vendors plants, and rece
12、iving inspec- tion at ammunition facilities. b. Provide visual defect standards for use in connection with acceptance inspec- tion of packed ammunition. c. Serve as a visual aid in the training of personnel engaged in the manufacture and inspection of bones and cans. d. Provide visual standards to b
13、e used as a guide in the evaluation of the resist- ance to corrosion of surface treated, painted steel boxes. 2. REFERENCED DOCUMENTS 2.1 Standards.

14、2 Specific. For the purpose of this stand- ard the following definitions shall apply: MIL-STD-406 1 February 1957 3.2.1 Permissible deject. A condition which, though no desirable from an appearance stand- point, may be permitted for reasons of economy, 3.2.2 Identul deject. A condition least desirab
15、le from an appearance standpoint, and the frequency of occurrence of boxes and cans having such defects is limited for acceptable lots by means of an Acceptable Quality Level. 4. GENERAL REQUIREMENTS 4.1 General. The descriptions and defini- tions of defects established in this standard are those co
16、mmonly occurring. Any other defects not listed, present in the lot, shall be reported. If, in the opinion of the Government inspector, the other defects be serious, complete informa- tion, recommendations and request for disposi- tion shall be submitted through proper channels. 5.
