SCOPE This specification defines the performance of marking inks for the identification
3、 of plastic, rubber and metal parts or the various gasket materials during production. The identification can either be a color spot or a printing. 2. APPLICATION Material according to WSS-M99P12-B1 is for temporary application only. Material according to WSS-M99P12-B2 is for temporary application a
4、nd has good resistance to engine oil, petrol and heat. Material according to WSS-M99P12-B3 provides excellent resistance to engine oil, ATF and heat and can be used for applications in the interior of engines and transmissions. The ink must not be removed prior to assembly (see also para 3.11). 3. R
5、EQUIREMENTS Material specification requirements are to be used for initial qualification of materials. 3.1 QUALITY SYSTEM REQUIREMENTS Material suppliers and part producers must conform to the Companys Quality System Requirements. 3.2 INFRARED SPECTROPHOTOMETRY AND/OR THERMAL ANALYSIS IR spectra and
6、 thermograms established for initial approval shall constitute the reference standard and shall be kept on file at the designated material laboratory. All samples shall produce IR spectra and thermograms that correspond to the reference standard when tested under the same conditions. ENGINEERING MAT

The specimen shall be cleaned and evaluated 1 h after test end. No loss of adhesion, no chipping or bli
14、stering. A slight color change is accepted. 3.10 COMPATIBILITY WITH CLEANING OPERATIONS (WSS-M99P12-B2 and B3) Compatibility with cleaning operations must be tested with actual parts under the process conditions of the relevant location. No loss of adhesion per para 3.4, no chipping or blistering. S
15、light color change is accepted. 3.11 LIFE TIME DURABILITY (WSS-M99P12-B3 only) The ink must not be removed prior to assembly of the part. Therefore its durability against all influences from liquids and heat in engines, transmissions, etc. under process conditions must be tested as required by Compo
16、nent Engineering. A feasibility report for each application must be added to the Initial Sample Report. ENGINEERING MATERIAL SPECIFICATION WSS-M99P12-B1/B3 Page 4 of 4 Copyright 2001, Ford Global Technologies, Inc. 3.12 SUPPLIERS RESPONSIBILITY All materials supplied to this specification must be eq
17、uivalent in all characteristics to the material upon which approval was originally granted. Prior to making any changes to the material originally approved under this specification, whether or not such changes affect the materials ability to meet the specification requirements, the Supplier shall no
18、tify the affected Purchasing, and Materials Engineering activities (with reasons) of the proposed changes. Upon notification of the Company, further instructions will be provided. Note: Suppliers should be prepared to provide test data and samples demonstrating compliance to this specification, if r
19、equested. Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document. The restrictions are identified in Restricted Substance Management Standard WSS-M99P9999-A1. 4. APPROVAL OF MATERIALS This specification is intended to define the perform
20、ance and/or properties of finished parts or systems of combined materials. An Engineering Material Approved Source listing is not applicable for this specification.
