This Appendixspecifies the rules forqualifyingper- sonnel to produce laminates and/or perform secondary bonding operations. Laminates and overlays thereof (secondary bonds) shall only be made by personnel who have been qualified in accordance with the rules of this Appendix. (b) A Laminator is an individual actively engaged (continually present and possessing full control over the process) in producing laminates. This is not to preclude assistance being provided to the Laminator by one to four assistants. (c) A Secondary Bonderis an individual who is actively engaged in joining and overlayingcured subassemblies of the vessel being fabricated. This is not to preclude assis- tance being provided to the Secondary Bonder by one or two assistants. (d) The Fabricator shall maintain up-to-date records relating to qualification ofeach Laminator and Secondary Bonder.Theserecordswilldocumentthedateoflastquali- ficationand will include all calculations and testorinspec- tion reports from both internal and independent laboratory testing programs used in the process ofquali- fication. These records are subjectto reviewonrequestby all parties engaged in the process of procurement or inspection. M5-200 RESPONSIBILITY It is the responsibility of the Fabricator to train and qualify Laminators and Secondary Bonders. M5-300 QUALIFICATION OF LAMINATORS (a) Laminators may qualify their capabilities at the time a Fabricator produces a demonstration laminate for the purpose of shop qualification. (b) To qualify, a Laminator must produce one Type II demonstration laminate (see Part 7), fabricated of any polyester or vinyl ester resin, which upon test in accor- dance with the instructions in Part 7 fulfills the require- ments ofthis Standard. A Laminator Qualification Report, Form M5-1, shall be completed and signed for each lami- nator qualification.
Prior to testing, the average engagement height of the shear collar must be determined for each secondary bond test specimen. (c) Measurements and calculations to determine the average engagement height of the shear collar must be done at the independent testing laboratory where the test specimens are to be tested. (d) To determine the average engagement height, H a , for each test specimen, proceed as follows: (1) Refer to Figure M5-3. (2) Using a vernier caliper, make three measure- ments of the shear collar height, L, at approximately 120-deg intervals and record the measurements in the Secondary Bonder Qualification Report. The average of the three measurements, L a , shall be calculated; the value shall be rounded off to the nearest hundredth of an inch (0.2 millimeter), recorded in the report, and also marked on each test specimen in approximately the area shown in Figure M5-3. Refer to para. formarkingrequirements.Measurementaccu- racy shall be ±0.010 in. (0.25 mm). (3) Using a vernier caliper with a depth slide, make threemeasurementsofthereliefboredepth,D,atapproxi- mately 120-deg intervals. Follow the same general proce- dures as in the preceding paragraph for recording measurements; averaging and rounding data to arrive at the average relief bore depth, D a ; and marking the specimen. Measurement accuracy shall be ±0.010 in. (0.25 mm).heatdeflection temperature:temperatureatwhichaspeci- fied bar specimen deflects 0.010 in.

Additionally, no commer- cial, financial, or individual relationships shall exist between the parties that might compromise efforts to produce and report accurate test results. It is expected, however, that a commercial purchase order, contract, or agreement will be employed by the parties to arrange for testing services. The independent testing lab- oratory must be equipped and staffed with the necessary skilled personnel to conduct the tests in accordance with the requirements of the Standard.
