2、OR NEW DESIGN 1. SCOPE This specification defines the performance and product requirements for automotive buffing and polishing pads. 2. APPLICATION This specification was released originally for material used for compounding service repair lacquer finishes, buffing out enamel finishes, and for appl
3、ication of cleaning and polishing compounds to automotive vehicles. This specification is not intended to limit the buffing and polishing pads to any specific material or material system but rather defines the performance of the entire system. 3. REQUIREMENTS 3.1 Shall be of such composition that th
4、ey meet all the requirements of this specification. They shall be capable of use with equipment normally available. 3.2 Shall be applicable for use on all types of automotive painted surfaces such as alkyd and acrylic finishes. 3.3 Shall withstand cleaning in order to extend their usable life. As a
5、result of washing or cleaning, there shall be minimal shrinkage, minimal loss of pile and no separation from the backing material. 3.4 To reduce the danger of burning work surfaces with the edge of the backing material, the pile shall overlap the backing material edge and shield the entire rim of th
6、e pad. 3.5 Shall be so constructed to allow buffing and polishing operations on all types of body contours and curves with ease and safety. 3.6 The pile shall be so constructed to maintain a cool, well balanced, snarlfree pad head. 3.7 Buffing and polishing pads having an arbor hole shall be balance
7、d rotationally and the arbor hole shall be effectively reinforced for longer use and wear. Cleaning the pads shall have a negligible effect on balance and rotation. 3.8 Adhesive used to lock the pile to the backing material, must withstand the action of rubbing compounds, cleaners, heat build up, wa
8、shing, and cleaning operations. 3.9 Shall not leave objectionable swirl marks, cut or burn, or leave other surface defects on the surface to which it is applied when used in the proper manner. ENGINEERING MATERIAL SPECIFICATION ESR-M99P3-A WP 3948-b Page 2 of 3 3.10 Shall conform to all applicable f
9、ederal, state, and local regulations. 3.11 Shall be so constructed that unraveling and loosening of pile ends shall be at a minimum. The pads shall not grab or stick to the vehicle surface while in operation. 3.12 CHEMICAL AND PHYSICAL PROPERTIES Specific chemical and physical properties are not spe
10、cified herein, but an Engineering Quality Control Supplement will be issued to cover each approved material. The selected engineering approved source shall furnish appropriate chemical and physical properties along with the production tolerance limits that apply to the material(s) upon which approva
11、l was given. The agreed upon values and limits will be issued to Quality Control by the affected Product Engineering Office. These values will then be used by Quality Control for ongoing quality verifications. The Quality Control Supplement is an integral requirement of this specification. If more t
12、han one source supplies material to this specification, a Quality Control Supplement will be issued for each specific approved material. 3.13 LABELING 3.13.1 Provisions of this specification are applicable when material is used according to labeling directions. Any precautions involved in the use of
13、 the material must be clearly stated on the product label. 3.13.2 The label(s) for the material(s) must comply to the Federal Hazardous Substances Act and all other provisions under the Consumer Product Safety Commission and all other applicable federal, state and local regulations. Supplier shall f
14、urnish the affected product engineering office with the label(s). 3.13.3 Supplier shall furnish certification that the composition of his product has been examined and that the label recommended is in compliance with the Federal Hazardous Substances Act and all other provisions under the Consumer Pr
15、oduct Safety Commission. Completed Material Health and Safety Data Sheets and Hazardous Substances Data Sheets must be submitted by the supplier to the Ford Motor Company toxicologist. 3.13.4 If applicable, supplier shall furnish a copy of the laboratory report wherein the product was evaluated unde
16、r the procedures required by the Federal Hazardous Substances Act. 3.13.5 Supplier must furnish detailed application instructions and specific usage information for container labels. This portion of the label information must be approved by the affected Product Engineering Office. 3.13.6 If the labe
17、l submitted by the supplier contains any advertising claims, suitable corroborative testing data must also be furnished. Such claims and data are encouraged. ENGINEERING MATERIAL SPECIFICATION ESR-M99P3-A WP 3948-b Page 3 of 3 3.14 MARKING Containers and cartons must be marked with a code indicating
18、 source and compounding date of the material. Supplier must furnish this code to the affected product engineering office. Container marking may be waived if approved in writing by the affected Product Engineering Office. 3.15 The test report data furnished by the supplier showing compliance with thi
19、s specification shall give the specific test methods followed and shall give specific answers to generalized requirements. 3.16 Generally accepted test methods (American Society for Testing and Materials, Society of Automotive Engineers and Ford Laboratory Test Methods are preferred) and procedures
20、should be followed where such methods are known, otherwise the methods of evaluation should be explained in detail. 3.17 SUPPLIERS RESPONSIBILITY Material supplied to this specification must be equivalent to that originally approved. Changes in formulation or processing shall not be made without pri
21、or approval as described in Supplier Procedure I-A. 4. APPROVAL OF SUPPLIERS Suppliers to this specification must be approved by the affected Product Engineering Office. Procedure for gaining approval of a specific material to a new/existing ES-M specification is contained in Supplier Procedure I-A.
22、 Approved new suppliers will be added to the Engineering Materials Approved Source List. 5. GENERAL INFORMATION This data is for information only and is not a requirement. 5.1 Comparative performance data ratings utilizing the requirements outlined above, comparing the proposed material(s) to presently marketed Ford Motor Company products, are encouraged.
