4.5 Inspections and tests.

4.5.1 General. The following inspections and tests shall be performed to comply with the requirements of this specification. They are not intended to limit or supplant any inspections and tests normally performed by the Contractor.

4.5.2 Documentation Review. The documentation required by paragraph 3.11 shall be reviewed for conformance with this specification and provided to the COR upon request.

4.5.3 Visual inspection. Each item shall be visually inspected to verify conformance with paragraphs 3.3, 3.7, 3.8, 3.9, and 3.10. Items failing to comply with the requirements of this specification shall be rejected.

4.5.3.1 Proof load test. The Contractor shall proof test each shackle assembly, shackle pin, Modeer shackle assembly, and swivel manufactured under this specification. Items which fail this proof testing prior to being offered for Coast Guard inspection may be reworked, or screened for defectives, and re-tested. This process shall be recorded on the QAIF (3.11.1). At the time of Coast Guard inspection, every shackle assembly, shackle pin, Modeer shackle assembly, and swivel offered shall have successfully passed the proof load test as specified in paragraph 3.4.

The Contractor shall certify this by submitting a Certificate of Performance (Appendix A) for each batch offered. In addition, at the time of Coast Guard inspection, the Contractor shall proof test the samples chosen in accordance with paragraph 4.4.2 in the presence of the COR. If any item fails the proof test at this time, it shall be considered a major defect.

4.5.3.2 Method of proof load testing. Shackle assemblies, Modeer shackle assemblies, and swivels shall be proof tested assembled. These items may be proof tested individually or in a series. When shackle pins are to be furnished alone, they may be proof tested individually, or by inserting them into shackle bodies of the appropriate class and tested as assemblies. Application of the proof load shall be at the centerline of the sample. The diameter of the attachments used in the proof tests shall not be greater than the size of the sample being tested.

Specification 417F Nov 2017

4.5.3.3 Breaking load test. The Contractor shall perform breaking load tests in the presence of the COR, using samples chosen in accordance with paragraph 4.4.2. Shackle assemblies, Modeer shackle assemblies, and swivels shall be break tested assembled. When shackle pins are to be furnished alone, they may be break tested individually, or by inserting them into shackle bodies of the appropriate class and tested as assemblies. Application of the breaking load shall be at the centerline of the sample. The diameter of the attachments used in the breaking load tests shall not be greater than the size of the sample being tested.

4.6 Inspection of packaging and marking. The Coast Guard inspection to determine compliance with the requirements of paragraph 5 will be performed at the point of destination. Items received at the point of destination which are not packaged and marked in accordance with the requirements of paragraphs 5 will be rejected.
