1、 ENGINEERING MATERIAL SPECIFICATION Date Action Revisions Rev. 0 2018 05 18 Released A. Reaume, NA Controlled document at www.MATS Copyright 2018, Ford Global Technologies, LLC Page 1 of 5 COOLANT, PHOSPHATED ORGANIC ADDITIVE TECHNOLOGY (POAT), WSS-M97B57-A2 PRE-DILUTED, FOR PASSENGER CAR AND LIGHT
2、TRUCK 1. SCOPE The material defined by this specification is a pre-diluted coolant mix based on WSS-M97B57-A1 coolant and purified water. This coolant is specified for plants that do not have sufficient water quality or the purification equipment required to properly condition the water. This coolan
3、t is also specified for use in post-production (service). Water quality will be monitored by the terminal mixing site. 2. APPLICATION WSS-M97B57-A2 is targeted to be a 50/50 pre-diluted engine coolant for plant fill. This material was originally released for passenger car and light truck application
4、s in areas where plant water quality would affect coolant performance. This material is also released for post -production (service) at 50/50 and other concentrations, depending on region, in order to ensure coolant quality. 3. REQUIREMENTS Ford Motor Company reserves the right to subject candidate
5、coolants to any investigation they may consider necessary and use the data derived for approval qualification. 3.1 DOCUMENTATION Supplier must furnish to the affected Materials Engineering activity a completed and certified copy of the attached supplement A, PVP&R (supplement B is an example of the
6、required report showing approval to WSS-M97B57-A1) and test reports demonstrating full compliance with all the requirements of this specification along with the manufacturing limits that apply to the material upon which approval is requested. All tests must be certified by a qualified and authorized
7、 representative of the test facility. This applies to a local blender supplying the formulation blended from a super concentrate (of an approved formulation) and is contingent upon initial approval of the formulation with test data where approved by Ford and testing and documentation, at minimum, in
8、 the attached PVP&R example (Supplement B). 3.2 COOLANT COMPOSITION Coolant must meet WSS-M97B57-A1 and be approved on the Ford Approved Source List. This specification requires the use of approved sources. Only the sources identified on the Ford Approved Source List (ASL) can be used when this spec
9、ification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.3 CONDITIONING AND TEST CONDITIONS All test values are based on material conditioned for not less than 24 h prior to
10、testing in a controlled environment of 23 +/- 2 C and 50 +/- 5% relative humidity. Testing of the material should occur in the conditioning environment or soon after removal.

11、F SOLUTION -37C max (ASTM D1177/D3321) 3.5 WATER QUALITY Water used in coolant dilution must meet the requirements of WSS-M99P25-C. Post production (service) in North America must also meet current ASTM D3306 requirements. Continuous water quality monitoring shall be used at the terminal blending si
12、te. In addition, quarterly full water quality analysis per WSS-M99P25-C is required. 3.6 BATCH ACCEPTANCE CRITERIA Shipments to vehicle assembly plants shall conform to Vehicle Operations General Office Bulletin VOPQG-236, Surveillance and Control of Fluids. Specifically for engine coolant Concentra
13、te. Supplement A, Supplier Certification Statement is also required. 3.7 HEALTH AND SAFETY The coolant supplied to this specification must not contain any nitrosoamine or triethanolamine or any other compound that, in the presence of nitrate, or nitrite, nitrogen oxides, or other nitrosating substan
14、ce, might product a nitrosoamine. 3.8 POST PRODUCTION (SERVICE) COOLANT Post-production(service) coolant concentration may be based on the regional requirements shown in paragraph 3.9 PRODUCTION COOLANT CONCENTRATION of WSS-M97B57-A1. Concentration must not exceed 50% or be less than the Minimum Coo
15、lant Concentration shown. Coolants shall meet all other requirements of this specification, except paragraph 3.4 if the concentration is other than 50/50. Coolants in North America shall meet the current ASTM D 3306 Type III coolant requirements. A copy of ASTM D3306 certification will be required i
16、n North America. Coolants must also meet the specific requirements of Ford Customer Service Division (FCSD). Supplier must work with FCSD and upon request furnish to FCSD all requested supporting documentation. 4. GENERAL INFORMATION This information given below is provided for clarification and ass
17、istance in meeting the requirements of this specification. Contact for questions concerning Engineering Material Specifications. 4.1 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and
18、Materials Engineering. The supplier shall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested material samples must be availab
19、le for review upon request and kept for a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.2 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equiv
20、alent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall notify the affected Supplier T
21、echnical Assistance (STA), Purchasing, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA.
