19、NTS 3.1 Description. Composition CH-6 is a homogeneous explosive mixture of RDX, graphite, calcium stearate and polyisobutylene. This mixture when compared to tetryl, withstands higher temperature before cook off, has higher output, yet matches the sensitivity of tetryl. The flow characteristics of
20、this mixture permit the manufacture of Composition CH-6 pellets of a density of at least 1.61 grams per cubic centimeter (g/cc) and various diameters that will hold together under ordinary handling conditions. 3.2 Fbt article. Unless otherwise specified in the contract or purchase order (see 6.2), a
21、 first article sample (see 6.3) shall be tested as specified in 4.4. 3.3 MatenalS. The materials used in the manufacture of the Composition CH-6 explosive purchased under this specification shall conform to their respective specifications prior to their usage and shall be of the type, grade, and/or
22、class as specified in 3.3.1 through 3.3.3 (see 6.6). 3.3.1 RDX explosive. The RDX explosive shall meet the requirements of MIGR-398, Type II, Class 1. 332 Graphite. The graphite material shall meet the requirements of MILG-155, Grade I. 333 Polyisobutylene. The polyisobutylene shall meet the require
23、ments of Polyisobutylene Vistanex LM-MH as manufactured by the Exxon Chemical Corporation, P.O. Box 3272, Houston, TX 77253, or equivalent. 3.4 Chemical and physical properties requirements. Unless otherwise specified in the contract or purchase order (see 6.2), Composition CH-6, Class 1 shall confo
24、rm to the requirements specified in Table I when tested in accordance with the applicable methods. Composition CH-6, Class 2 shall conform to the requirements of Table I, with the functioning characteristics as specified in the contract or purchase order (see 6.2). 3.5 Workmanship. The manufacturer
25、shall use procedures and controls which will ensure that the Composition CH-6 produced does not contain foreign material such as dirt, rust, paint, metal chips or other foreign substances which may cause a detrimental effect on the safety and reliability of the explosive. The workmanship exhibited i
26、n the first article sample shall be evaluated to determine acceptability. The approved standards of workmanship shall thereby become the minimum workmanship standards for the production of the explosive. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-

The material shall have no adverse e
32、ffect on the health of personnel when used for its intended purpose. Questions pertinent to this effect shall be referred by the contracting activity to the appropriate departmental medical service who will act as an advisor to the contracting agency (see 4.1.2). 3.64 Material safety data sheets. Th
33、e contractor shall prepare and submit Material Safety Data Sheets in accordance with FED-STD-313 as specified in the contract (see 6.7). 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order (see 6.2), the contractor is respon
34、sible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein,
35、 unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements. 4.1.1 Responsibility for compliance. All material
36、s shall meet all the requirements of sections 3 and 5. The inspections set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirement in the specification shall not relieve the contractor of the responsib
37、ility of ensuring that all materials submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements. However, this does not authorize submission of k
38、nown defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.14 Toxicological produd formulations.
