1. Scope

This standard covers the source approval methods for all engine oil coolers used on Heavengines built by Cummins Engine Company.

2. Applicable Documents

Applicable documents listed below may be obtained from the respective organizations lisCES 10054, Standard Organization Addresses.

a. CES 10012, Source Approval Listinga. CES 10054, Standard Organization Addressesb. CES 10056, General Glossaryc. CPM 0295-15, Source Approval Testing

3. Definitions

There are no unique definitions in this standard. Terms used in this standard that have a gdefinition for usage in Cummins Engineering Standards are defined in CES 10056, GeGlossary.

4. Specification

The following requirements are to be performed in listed order. Rejection at any level will stoevaluation until corrective action is taken and new samples submitted. These requirements aapplicable of any changes in manufacture or processing proposed by the supplier prior to inrating the changes into production.

Compliance with CPM 0295-15 must be met prior to source approval testing.

4.1. Dimensional Approval

Submitted samples must agree with their corresponding engineering drawing dimensionallyferences can be waived only by agreement with Chief Engineer on engine using the oil cooquestion.

4.2. Material Approval

Submitted samples must agree with their corresponding material standard. Differences cwaived only by agreement with Chief Engineer on engine using the oil cooler in question. Theterial standard shall be obtained from the sample’s corresponding engineering drawing.

Responsibility: Quality

4.3. General Test Requirements

4.3.1. Heat Rejection Test

Perform a heat rejection test per Cummins latest oil cooler test method,which will provide cof heat rejection versus oil flow rate at various test conditions. The result will be comparedtheoretical performance requirements and/or the performance of the standard production pa

4.3.2. Structural Integrity Test

4.3.2.1. Perform a pressure cycle test per Cummins latest oil cooler test method, on thfive sample coolers. Inspect tube bundles for signs of collapse or of leakage.

4.3.2.2. Perform a thermal cycle test per Cummins latest oil cooler test method. Inheader joints for signs of failure. Three consecutive units must pass.

4.3.2.3. Perform a vibration test per Cummins latest oil cooler test method.

4.3.3. Supplier Test Correlation

Auditing of the suppliers cooler element performance on a production basis will be performeQuality Engineering. They can have the heat transfer measured at R & E Heat & Fluids or mtesting at the supplier’s facility. Since the test results differ somewhat with the equipment it isessary to establish test correlation between Cummins and the supplier. This will permit theopment of a performance baseline for the elements tested on the supplier’s equipment.

The test correlation and the subsequent "supplier baseline" should be developed as follows

4.3.3.1. A current production element should be tested at Cummins latest oil coolemethod and sent to the supplier. It is to be used as his standard.

4.3.3.2. The supplier should test the unit and return a copy of the results to Cummins.

4.3.3.3. The Cummins test results of the suppliers "standard" should be plotted againCummins baseline. It will be a parallel curve proportionately higher than the baseline.

4.3.3.4. The suppliers test result should also be plotted. The performance baseline fequipment can be estimated by applying the above proportion to the tested result and plott"baseline" curve.

4.3.3.5. This estimated suppliers baseline should be included in the Cummins report wfor the final approval documentation. If there are questions concerning the correctness of aresult the Cummins test shall prevail.

5. Qualification for Release

Upon successful completion of test requirements and receipt of test reports by the originatoriginator will request Product Engineering to issue a deviation for limited production usage osubject oil cooler for 6 months at 20 percent of annual production requirements. A heat rejetest shall be performed on two elements from the first production shipment. Upon succescompleting the heat rejection test and the limited production, Product Engineering shall releasupplier for unrestricted production usage of the oil cooler with the addition of the supplier toproved Source List 10012, in accordance with CPM 0295-15. The Executive or Chief Engcan, by written authorization, waive any or all parts of the above standard.
