5、xposure, the panels shall be cut intoindividual specimens and tested in accordance with 4.5.5.9.4.4.1.4 Cleavage strength. Cleavage panels shall be bonded metal inaccordance with ASTM D1062-51. For acceptance tests two panels as shown infigure 2 shali be bonded and prepared.4.5 Qualification tests.1

Unless otherwise specified by the pro-curing activity, adhesives which have previously passed the qualification testsbut have subsequently been modified in any mann
7、er, shall satisfactorily pass re-testing of the material in order to retain qualification approval. Qualificationtests may be repeated on material previously found satisfactory at any time atthe option of the activity responsible for qualification approval.4.5.2 Sampling instructions. The manufactur
8、er shall submit a dupli-cate set of bonded panels and specimens which shall be prepared as specified in4.4 and subparagraphs thereto. These panels shaII be prepared with adhesivesamples from the same three batches of adhesive and shall be code marked thesame as the panels upon which the data given i
9、n the test report (4.5.3) wereobtained. The manufacturer shall also submit four l-pint samples of liquid adhe-sive together with necessary curing agents, or an equivalent amount of materialin weight or measure if of another form, from each of three different numberedbatches of the adhesive being pre
10、sented for qualification. These adhesive sam-ples shall each be from batches of most recent production-scale manufacture, andmay be from different batches than those used in preparing the above specifiedset of duplicate panels. Part of the adhesive samples from each batch will beused in preparing te
11、st panels for qualification tests and the balance will be usedfor storage life tests (4.5. 5.11). AH samples shalI be identified as to name ofmanufacturer, manufacturers designation, date of manufacture, base polymer andcuring agents (as applicable ), the date of submittaI, and identification of the
12、 ac-tivity submitting the samples, and forwarded to the Naval Air Development Cen-ter (see 6.4). In addition, a statement indicating that the products have notbeen rebranded shall accompany the samples. If rebranded, the names of theoriginal manufacturers and original designations of the products sh
13、all be indi-cated. All information submitted will be treated as confidential.4.5.3 Test report. Prior to conducting the qualification tests(4. 5.5 ), a dated and numbered report, certified by notarized affidat, shall befurnished, giving the results of alI applicable tests listed in table 1. The indi
14、-vidual specimen and average values for each test shaIl be reported (see 6.4.2).Each value reported shall be shown as being for a definitely numbered specimen,the numbering of which shall be coded in the report in such a manner as to def-initely establish the particular panel from which the specimen
15、 was cut and theparticular batch of adhesive with which said panel was bonded and the date ofbonding. Coded identification of the adhesive batches shall include the respec-tive dates of manufacture and sizes of batch. Dates on which the different testswere performed shall be shown in the test report
16、. The test report shall alsocover all the requirements of paragraphs in section 3 (except 3.5). The actualpressure, temperature, and time of curing used in the preparation of the testpanels shall con form to the description given in the instruction sheet and thereport shall so state.16Provided by IH
