Generally, products are usable over a temperature range of -76 to +302 F (-60 to +150 C). Each application, however, has to be

7、considered individually. 1.3 Safety-Hazardous Materials While the materials, methods, applications, and processes described or referenced in this specification may involve the use of hazardous materials, this specification does not address the hazards which may be involved in such use. It is the sol

8、e responsibility of the user to ensure familiarity with the safe and proper use of any hazardous materials and to take necessary precautionary measures to ensure the health and safety of all personnel involved. 2. APPLICABLE DOCUMENTS The issue of the following documents in effect on the date of the

9、 purchase order forms a part of this specification to the extent specified herein. The supplier may work to a subsequent revision of a document unless a specific document issue is specified.

27、ange in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems confirmatory testing to be required. 4.2.2.1 Manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspection on production product which are essentially the same as thos

28、e used on the approved sample. If necessary to make any change in ingredients, in type of equipment for processing, or in manufacturing procedures, manufacturer shall submit for reapproval a statement of the proposed changes in ingredients and/or processing, and, when requested, sample product.

30、l be as follows: 4.3.1 For Acceptance Tests Sufficient product shall be taken at random from each lot to perform all required tests. The number of determinations for each requirement shall be as specified in the applicable test procedure or, if not specified therein, not less than three. 4.3.1.1 If

31、specimens cannot be prepared from the product, ASTM test specimens prepared from the same batch and state of cure shall be used for required tests. When the product supplied is an extrusion of such shape that suitable test specimens cannot be cut from the product, a separate flat strip test sample,

32、from the same production lot, shall be supplied upon request. This strip shall be prepared from tubing 1.000 inch 0.063 (25.40 mm 1.60) in OD by 0.075 inch 0.008 (1.90 mm 0.20) in wall thickness, mechanically slit and flattened into a strip while being extruded, and cured in the same manner as produ

33、ction product. When the product is a molded shape from which test specimens cannot be cut, a slab 6 inches (152 mm) square by 0.075 inch 0.008 (1.90 mm 0.20) thick, molded from the same batch of compound, shall be supplied upon request.4.3.1.2 A lot shall be all product from the same batch of compou

34、nd produced in one continuous run and presented for manufacturers inspection at one time. 4.3.1.3 A batch shall be the quantity of compound run through a mill or mixer at one time. 4.3.1.4 Final Inspection Sampling Plan A statistical sampling plan acceptable to the purchaser may be used in lieu of s

35、ampling as in 4.3.1. Sample size for visual and dimensional requirements shall be as shown in Table 3; sample unit shall be one molded part and acceptance based on zero defects.

37、 For Preproduction Tests As agreed upon by purchaser and supplier. 4.4 Approval 4.4.1 Manufacturer shall establish for each size of part, parameters for the process control factors which will produce parts meeting the technical requirements of this specification. These shall constitute the approved

38、procedures and shall be used for manufacturing production of parts. If necessary to make any changes in the parameters for process control factors, manufacturer shall submit for reapproval a statement of the proposed changes in ingredients, and/or processing. Products manufactured using a revised pr

39、ocedure shall not be shipped prior to reapproval in writing. Manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspection, which are essentially the same as those used on the approved sample. 4.4.1.1 Control factors for producing products include but are not lim

40、ited to, the following: Compound ingredients and proportions thereof within established limits Sequence of mixing compound ingredients Type of mixing equipment Method and equipment for preparing preforms Basic molding procedure (compression, transfer, injection) Curing time and pressure; variations

41、of 10% are permissible Finishing methods Methods of inspection 4.4.1.2 Any of the above process control factors for which parameters are considered proprietary by the manufacturer may be assigned a code designation. Each variation in such parameters shall be assigned a modified code designation.4.5

42、Reports The supplier of the product shall furnish with each shipment a report showing the results of tests to determine conformance to the acceptance test requirements and stating that the product conforms to the other technical requirements. This report shall include the purchase order number, lot

43、number, AMS3331B, manufacturers compound number, form and size or part number, and quantity. 4.6 Resampling and Retesting If any specimen used in the above tests fails to meet the specified requirements, disposition of the product may be based on the results of testing three additional specimens for

44、 each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the product represented. Results of all tests shall be reported. 5. PREPARATION FOR DELIVERY 5.1 Identification and Packaging Shall be as stated on the purchase or

45、der or contract requirement, when no requirements are stipulated, packaging shall be in accordance with AMS2810. 5.1.1 A lot of product may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained.
