Opportunities for intervention by Daimler AG

The Daimler AG project managers have the right to intervene into and peruse these documents, which are

specially drawn up for Daimler.

Preface:

Proposals regarding detailed solutions on the part of a potential contractor are expressly desired. Particularly if

these serve as distinguishing features in comparison with competitors and correspond to the buyers' interests.

The integration of such solutions must be achievable within the framework of the cost target and scheduling.

The contractor is obliged to carry out his service using experienced and qualified personnel.

If additional companies are engaged as development partners/sub-suppliers, Daimler AG must be notified of

this.

Within the framework of this concept competition, the potential contractor must establish technical

specifications.

Should, contrary to expectation, different requirements be defined for a particular function or characteristic in

these requirement specifications, the more demanding requirement applies in all cases.

The technical specification must reflect the structure of the requirement specification. Deviations from the

requirements stated in this requirement specification must be explicitly identified in writing in the technical

specification. If deviations are not identified, the stipulations contained in this requirement specification take

precedence.

This requirement specification and the technical specification (supplier) form parts of the agreement as

technical appendices.

In the event of questions regarding the content of this requirement specification, please contact the author or

the authoring department.

Secrecy:

The results which have been generated may only be published or passed on to third parties with the approval of

Daimler AG. The contractor must oblige both his employees and any subcontractors to adhere to these

regulations. The contractor is also obliged to adhere to Point 5 of the purchasing conditions pertaining to

production material and spare parts for motor vehicles. Further details are regulated by a separate secrecy

agreement.

Blocking note:

All versions, data and contents of this requirement specification must be treated in strict confidentiality and

may not be put to further use or made accessible to third parties without the written approval of Daimler AG.

Reprinting and copying, including excerpts, are not permitted. This blocking note applies unreservedly.

3.2 Costs and Cost-Effectiveness

Beside qualitative aspects, also the remanufacturing process and incidential costs will be checked by

responsible contact person at Daimler AG Pre-Cost Planning.

3.3 Tooling Costs

Supplier provides all necessary tooling and is therefore owner of all tooling equipment provided by

themselves.

3.4 Core Process

For remanufacturing of air-assisted urea pump module, cores are provided by Daimler AG.

The acquisition of cores depends on delivery order from Global Logistics Center Germersheim and is steered

The accounting of cores is executed by Daimler AG with a price per unit negotiated with Daimler AG purchas-

ing Department. Daimler AG delivers the cores to Supplier Germany exclusively for remanufacturing purpos-

es for Daimler AG.

The number of cores used for remanufacturing is documented and will be communicated to Core Consolida-

tion Center in Offenbach on a quarterly basis.

Scrapping of cores which cannot be used for remanufacturing will be documented by Supplier. Scrapping

documentation can be claimed by Daimler AG at any time. Daimler AG is allowed to conduct random inspec-

tions.

3.12 Labelling

The marking is to be made – depending on the existing or planned marking system, service life and quality re-

quirements – directly on the component by an inkjet printer, laser or a dot marking machine. In exceptional

cases, i.e., where there is good reason to use alternative marking processes, these are to be approved by

Daimler. Every part that is given a marking is to be presented to Daimler for inspection of code quality and

surface.

Humanly legible marking must be chemically and physically resistant; resistant to mechanical strains arising

during the remanufacturing process, transportation and the processing of common materials; resistant to

temperatures between –40°C … +85°C; and legible by machine for the duration of a vehicle service life of 15

years.

For the traceability of all parts, the supplier must ensure that a link is established between human readable

identification number and its database. The type of link is left to the manufacturer.

When issues with noticeable parts arise, Daimler shall provide the supplier with the data of the component in

question and must receive from the supplier a reply stating which other components named by the human

readable identification number are affected or which individual parts / individual part numbers are installed.

These documents are to be archived and made available on demand at the supplier after the expiration of the

15-year series production.

The respective markings of individual components must not in any way influence the functionality, safety or

established values from the specifications for the components and the overall system for the duration of the

product service life of individual components and the overall system.

4.1.3 General component repair

A general component repair is not acceptable unless statistical and reliability data prove that repaired

components meet the OEM technical requirements. Component repair on critical parts i.e. housing, motor is

not accepted.

4.1.4 Electric Components Requirements

Winding must be checked for short to ground or for short between the windings. Winding resistance must be

measured and verified.

Brush holder functionality must be given. Any kind of damage of the brush holder are not acceptable and

must be replaced. Brushes must be replaced by shortening (length < 80%). Springs must be replaced.

Commutator roundness must be within cirularity tolerance. Commutator must be even by lathe to remove

brush marks to achieve necessary grinding surface for high and stable functionality and durability.

4.2 Miscellaneous

4.2.1 General data

According to Drawings.

4.2.2 Tightening – Loosening torque

The tightening torque for bolts and nuts must achieve OE values according to drawing specification.

Deviations can be agreed on a separate appendix sheet if required and must be validated for tightness.

For part numbers A 000 140 15 78, A 000 140 27 78 and all urea pump modules without metal screw

thread in plastic housing, loosening torque must be validated and documented, to ensure tight closed

housing during operation conditions. Test results and reports must be provided to Daimler AG.

4.2.3 Operating condition

Temperature limits of individual components shall not be exceeded while operating at specified temperature

range.

4.2.4 IMDS – International Material Data Sheet

International Material Data Sheet must be considered to fulfil international laws und regulations regarding

materials used in automobile industry. IMDS can be considered in /be part of process and product audit

performed by Daimler AG.

4.3 Testing and Validation

A testing and validation of all remanufactured urea pump module – Air Assisted part numbers is required

prior to the technical release of each part. For replacement parts from non OE supplier and for paintwork

and screw connection/ Gluing concepts a temperatur shock test under continous monitoring of the device

under test and a sinusoidal vibrations test are required. Supplier must provide samples to Daimler AG.

Validation tests (salt spray, temperature shock test, sinusoidal vibration) will be performed by Daimler AG.

Test results must be documented in a final test report and be provided.

4.3.1 Product Validation

For product validation, test samples (one piece per each part number) have to be tested according to the

following procedure and have to be fully functional afterwards.

4.3.2 Functional Test

Supplier must perform 100% functional test.

Supplier must specifiy functional test procedure.

Supplier must perform functional test for each part number in reman process.

Supplier must fulfil drawing specifications.

4.4 Residual requirements

Every component has to fulfill a certain degree of cleanliness in order to assure proper functionality of the

Urea Pump Module – Air Assisted. Cleaning results have to be verified. A certain amount of residuals can

cause malfunctions. Malfunctions are not allowed. The functional and visual cleanliness of components has

to be specified during the project to ensure constantly high quality.

Residual requirements of Mercedes-Benz Genuine Remanufactured Part - Urea Pump Module – Air Assisted

is specified in DBL 6510 – Technical Cleanliness of Mercedes-Benz.
