Part 1 of this specification covers the material properties, performance requirements, production quality and process control, supplier’s responsibility, source approval and quality control, general information, and sources for approved adhesive systems. This specification should be viewed as a Design Requirements Document Template or Test Plan Template for applications using a PSA type bonding system. In all cases, it is the discretion of Navistar Materials Engineering group as to which requirements are pertinent to the application. The process should follow these steps:

1. Engineering reviews a PSA application with Materials Engineering and releases prints referencing this specification if the application is appropriate and Materials Engineering concurs.

2. Supplier submits and reviews a test plan to this specification with guidance from Materials Engineering and other appropriate groups at Navistar.

3. The test plan may be approved or modified. Once accepted, the supplier shall commence testing to the approved plan.

4. Upon test completion, the report is submitted to Materials Engineering and reviewed with other groups as necessary.

5. If the results are deemed acceptable, a report documenting approval of that application with those specific materials will be issued by Materials Engineering.

6. On a future revision of this specification, that report number and pertinent information will be listed in Table 5 if appropriate.
