1 DAIMLERCHRYSLER CORPORATION No: MS-9680 Material Standard Date Published: Category Code: H-2 Change: C EASL Req.: Yes Restricted: No MILL OILS AND EDGE SEALERS - SHEET METAL 1.0 GENERAL 1.1 Purpose of the Standard This standard presents the requirements for mill or processor applied corrosion inhibiting oils and edge sealers. These oils and edge sealers are typically applied at the steel mill or subsequent blanking facilities to protect the sheet metal from corrosion due to environmental exposure during transportation and storage prior to stamping. In addition, the mill oils offer protection between stamping and subsequent painting operations and provide lubricity that may be required for some manufacturing processes. 1.2 Purpose of the Material In this standard, mill oils are corrosion inhibiting oils applied to the flat surfaces of a sheet or strip and edge sealers are corrosion inhibiting products applied to the coil edges. 1.3 Requirements Any requirements shown on CATIA, Engineering Graphics, or other engineering illustrations shall take precedence over the requirements listed in this standard. 2.0 MATERIAL CHARACTERISTICS This material shall comply with all the requirements of the Clean Air Act (USC 1857, as amended) and any applicable federal, state, or local statue pertaining to the establishment and maintenance of the National Ambient Air Quality Standards as administered by the Environmental Protection Agency (EPA) or any authorized state or local governmental unit. The Material shall not have an objectionable or noxious odor. It shall be the supplier's responsibility to determine through the Industrial Hygiene and Safety Department, DaimlerChrysler Corporation, that the materials contained in the material and the contemplated use thereof are deemed to be non-objectionable. The supplier shall properly label the material stating any hazardous properties and precautions to be taken in usage of the material. 3.0 CHEMICAL COMPOSITION The material shall be formulated to eliminate constituents that would be classified as hazardous under the Resource Conservation and Recovery Act (40 CFR , as amended) and any applicable federal, state or local statue regulating the composition of liquid or solid wastes, as administered by the EPA or any authorized state or local governmental unit. Material submitted for laboratory approval, if containing hazardous materials, or if determined to generate hazardous waste products during plant usage, must be accompanied by the appropriate RCRA analysis document(s) for the virgin material and/or the generated waste.

2 4.0 PERFORMANCE REQUIREMENTS OF THE MATERIAL 4.1 Lubricity and Formability Lubricants approved to this standard shall meet the minimum requirements for formability and lubricity as procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, 4.2 Weldability Lubricants approved to this standard shall meet the minimum requirements for resistance spot welding as existing approved control samples in laboratory testing and in production trials, and not exhibit any deleterious effects to the weld quality, welding equipment, or process. Testing methods and procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, 4.3 Adhesive and Sealer Compatibility Lubricants approved to this standard shall meet the minimum requirements for adhesive and sealer compatibility as established by the Materials Engineering Department, Vehicle Engineering Office, New materials submitted for approval shall meet or exceed performance levels obtained by existing approved control samples in laboratory testing and in production trials. Testing methods and procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, 4.4 Cleanability Lubricants approved to this standard shall meet the minimum requirements for cleanability (ease of removal from the substrate prior to subsequent phosphating and electro-coat primer operations), as procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, 4.5 Phosphate and Electro-coat Primer Compatibility Lubricants approved to this standard shall meet the minimum requirements for compatibility with approved phosphating and electro-coat primer chemicals and processes, as established by the Materials Engineering Department, Vehicle Engineering Office, New materials submitted for approval shall meet or exceed performance levels obtained by existing approved control samples in laboratory testing and in production trials. Testing methods and procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, DaimlerChrysler Corporation. 4.6 Corrosion Resistance Lubricants approved to this standard shall meet the minimum requirements for corrosion protection on stamped components and test assemblies, as established by the Materials Engineering Department, Vehicle Engineering Office, New materials submitted for approval shall meet or exceed performance levels obtained by existing approved control samples in laboratory testing MS-9680, Change C, , Page 2

3 and in production trials. Testing methods and procedures shall be as directed by the Materials Engineering Department, Vehicle Engineering Office, 4.7 Bake/Stain Resistance Lubricants approved to this standard shall not react with the metal substrate in a manner that results in localized oxidation and staining. The lubricant shall meet the minimum requirements for Bake Stain, as established by the Paint and Energy Management Department, Manufacturing Division, DaimlerChrysler procedures shall be as directed by the Paint and Energy Management Department, Manufacturing Division, 4.8 Production Evaluation Requirements After successfully completing laboratory testing requirements, lubricants submitted for approval to this standard must meet minimum requirements for process and process capability. This shall be established through successful completion of a production evaluation. The requirements, (duration, assemblies to be tested, volumes, etc.) shall be established and coordinated by Body-In-White Stamping Division, the using facility, and DaimlerChrysler Procurement and Supply. 5.0 APPLICATION The sheet metal supplier shall apply a mill oil coating mass on the sheet metal that meets the criteria specified in the Table 1 unless otherwise specified by the using DaimlerChrysler facility. For corrosion protection purposes, the DaimlerChrysler facility shall not, however, specify a mill oil coating mass of less than 1 g/m 2 (100 mg/ft 2 ). The mill oil coating mass minimum specified in Table 1 is per side. The coating mass shall be determined using a weigh-strip-weigh measurement method. Alternative measurement techniques may be used to measure mill oil coating mass if supporting correlation documentation between the weigh-strip-weigh method and the alternative measurement technique is provided to Materials Engineering Department, Vehicle Engineering Office, The sheet metal supplier must make statistical process control data for mill oil coating mass available to DaimlerChrysler upon request.
