SCOPE 1.1 Form This specification covers a silicone rubber sponge in t
6、he form of sheet, strip, extrusions, and molded shapes. 1.2 Application This sponge has been used typically for general applications requiring closed-cell, firm sponge rubber that will be flexible from -166 to +401 F (-110 to +205 C) but usage is not limited to such applications. Compression set may
7、 be high at the higher temperature. 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.

QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for Inspection The manufacturer
21、 of sponge shall supply all samples and shall be responsible for the performance of all required tests. Purchaser reserves the right to sample and to perform any confirmatory testing deemed necessary to ensure that sponge conforms to specified requirements SAE INTERNATIONAL AMS3194E Page 4 of 5 4.2
22、Classification of Tests All technical requirements are acceptance tests and preproduction tests and shall be performed prior to or on the initial shipment of sponge to a purchaser, on each lot, when a change in ingredients and/or processing requires reapproval as in 4.4.2, and when purchaser deems c
23、onfirmatory testing to be required. 4.3 Sampling and Testing Shall be as follows: 4.3.1 For Acceptance Tests Sufficient sponge 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 procedur
24、e or, if not specified therein, not less than three. 4.3.1.1 A lot shall be all sponge from the same batch of compound, processed in one continuous production run, and presented for manufacturers inspection at one time. 4.3.1.2 A batch shall be the quantity of compound run through a mill or mixer at
25、 one time. 4.3.1.3 A statistical sampling plan, acceptable to purchaser, may be used in lieu of sampling as in 4.3.1 and the report of 4.5 shall state that such plan was used. 4.3.2 For Preproduction Tests Shall be acceptable to purchaser. 4.4 Approval 4.4.1 Sample sponge shall be approved by purcha
26、ser before sponge for production use is supplied, unless such approval be waived by purchaser. Results of tests on production sponge shall be essentially equivalent to those on the approved sample. 4.4.2 Manufacturer shall use ingredients, manufacturing procedures, processes, and methods of inspecti
27、on on production sponge which are essentially the same as those 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 ingredient
28、s and/or processing and, when requested, sample sponge. Production sponge made by the revised procedure shall not be shipped prior to receipt of reapproval. 4.5 Reports The supplier of sponge shall furnish with each shipment a report showing the results of tests to determine conformance to the techn
29、ical requirements. This report shall include the purchase order number, lot number, AMS3194E, manufacturers identification, form 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 sponge may
30、be based on the results of testing three additional specimens from the same lot for each original nonconforming specimen. Failure of any retest specimen to meet the specified requirements shall be cause for rejection of the sponge represented. Results of all tests shall be reported. 5. PREPARATION F
31、OR DELIVERY 5.1 Identification and Packaging Shall be in accordance with AMS2810. SAE INTERNATIONAL AMS3194E Page 5 of 5 5.1.1 A lot of sponge may be packaged in small quantities and delivered under the basic lot approval provided lot identification is maintained. 6. ACKNOWLEDGMENT A supplier shall
32、mention this specification number and its revision letter in all quotations and when acknowledging purchase orders. 7. REJECTIONS Sponge not conforming to this specification, or to modifications authorized by purchaser, will be subject to rejection. 8. NOTES 8.1 A change bar (|) located in the left
33、margin is for the convenience of the user in locating areas where technical revisions, not editorial changes, have been made to the previous issue of this document. An (R) symbol to the left of the document title indicates a complete revision of the document, including technical revisions. Change ba
34、rs and (R) are not used in original publications, nor in documents that contain editorial changes only. 8.2 Dimensions and properties in inch/pound units and the Fahrenheit temperatures are primary; dimensions and properties in SI units and the Celsius temperatures are shown as the approximate equivalents of the primary units and are presented only for information. 8.3 Purchase documents should specify not less than the following: AMS3194E Form and size or part number of sponge desired Quantity of sponge desired.
