9。3。2。Radiographic and other quality standards shall be as agreed upon by vendor  and Honeywell Turbo Technologies。

9。3。3。Castings shall be produced under radiographic control。 This shall consist of radiographic examination of castings until proper foundry technique, which will produce castings free from harmful internal defects, has been established for each mould and of production castings as necessary to ensure maintenance of satisfactory quality。

9。4。Casting Repair

9。4。1。Castings shall not be repaired by plugging, welding or other methods without written approval from the Honeywell Turbo Technologies。 Any weld repair shall conform to the applicable weld repair specification。

9。4。2。Castings shall not be impregnated, chemically treated or coated unless authorized in writing by Honeywell Turbo Technologies。 If impregnation is approved the applicable specification shall be used。

9。5。Retesting

If initial test results fail to meet requirements and material is re-tested, such re-tests must be carried out per QCI-9310-175。

9。6。Identification

Specified castings shall be identified in accordance with the engineering drawing and in accordance with PI-5780。

10。Reports

10。1。Unless otherwise specified, the supplier shall retain at their facility the results of tests that determine conformance of the parts to the requirements of this specification。 Evidence of such is to be on file for examination for a period of five years from the date of shipment。

10。2。The reports shall show the chemical composition, mechanical properties, microstructure, material specification number (IDM and international material designation) and revision letter, purchase order number and quantity。 Honeywell Turbo Technologies reserved the right to perform tests to verify that the material meets the requirements and to reject non-conforming material。
