1613.1 Description
This specification governs products for various applications cast from malleable iron.
1613.2 Requirements
a. General. Provide castings that comply with the design, dimensions, requirement for corrosion protection, and specific fabrication requ irements specified in the Contract Do cuments. Unless corrosion protection is specified, the cast products are to be provided in the as-cast and as-machined condition. b. Material Specifications.

1613.3 Test Methods.
Conduct all tests required by the applicable ASTM specifications of subsection 1613.2b. Measure coating thickness by any one of the methods specified in AS TM B 633 and by eddy curr ent methods, ASTM B 244, provided that appropriate calibration procedures and standards have been applied. The magnetic induction and eddy current methods are nondestructive in nature and are preferred. Destructive techniques, i.e., coating removal, may be utilized as referee methods.
1613.4 Prequalification
Not applicable.
1613.5 Basis of Acceptance.
Receipt and approval of a Type D certification as specified in DIVISION 2600. Inspection and testing by field personnel of all co mponents for compliance with dimensional requirements and corrosion protection coating thickness when corrosion protection is specified. Coating thickness is to be measured according to any of the procedures of subsection 1613.3. The final disposition of all components will be complete d at the final destination as the result of inspection for the quality of workmanship and the delivery condition.
