5、ble for its intended application. 4.1 Prime Paint Cab suspension modules shall be finished with a prime paint, or corrosion resistant compound, or coating, meeting the requirements of Class II, per TMS-9009. Color of the prime paint or coating is to match NAV 0004 black. All paintskoatings used on t
6、he suspension modules must be compatible for re-coating with topcoat paints used in International Assembly Plants. 4.2 Design Requirements 4.2.1 Material Specifications Material(s) specified for the bracket(s) are to be identified either to International CEMS specifications or to other recognized in
7、dustry standards. 4.2.2 Clearance Air spring clearance shall be at least 0.25“ from any object when air spring is at maximum design size.

9、e expectancy established for each truck vocation as follows: RH vocation; 1 200 O00 miles, except shocks 250 O00 miles and height control valve 500,000 miles: SS vocation; 300 O00 miles, except shocks 75 O00 miles and height control valve 150 O00 miles: IC vocation; 350 O00 miles, except shocks 100
10、O00 miles and height control valve 250 O00 miles 4.2.4 Noise The noise transmissibility Vs frequency through the assembly, in the vertical and lateral directions, will be measured in a bench test with equivalent cab static weight simulated by a concentrated mass and the shocks hydraulically locked.
11、Transmissibility shall be less than 0.5g for inputs of 30 Hz and above, with 0.020 inch DA up to 22Hz, and 0.5g above 22 Hz. The equivalent cab static weight is dependent upon cab type. (Type CS cab has a static weight of 550 lbs.). 4.2.5 Performance-Frequency Natural frequency of the cab suspension
12、 module in the vertical direction shall be less than 2.0 hertz. 4.3 Testing; Requirements Supplier test reports will be in accordance with TMS-9543. All testing performed by the supplier is subject to validation by TDTC Technical Development Department. International will specify, coordinate, and pe
13、rform all on-highway testing. 4.3.1 Roof Crush Testing When properly installed, the cab suspension module shall be of sufficient strength to keep the cab attached to the chassis throughout the entire roof strength testing procedure specified in ECE-R29 andor SAE 52422. When subjected to this strengt
14、h testing the module will not deflect in a manner that compromises the ability of the cab to withstand the specified loads. 4.3.2 20 G Pull Apart Test The cab suspension module shall not separate when subjected to a quasi-static force equal to the force resulting from a 20 G forward acceleration of
15、the cab parallel to the longitudinal axis of the chassis. The force is calculated by assuming the acceleration results in a force equal to 20 times the weight of the fully trimmed and occupied cab, acting through the cabs center of gravity, in a forward direction. The forward cab mounts are friction
16、less, pinned connections, and it is assumed that the sum of the moments about the front cab mounts equal zero. During testing the module will be mounted in the same manner as will be used to mount the module in the vehicle. 5.0 QUALITY All modules supplied will be clean and free from dirt, oils, or
17、defects harmful to product performance. Color and texture shall be uniform and consistent with samples that were originally approved. 5.1 Quality Control Plan A Quality Control Plan for this product will be established by mutual agreement between Navistar and the supplier. The following items, where
18、 applicable,* shall be included in the control plan as features for management by statistical process control.* 5.1.1 Air Springs, Installed Heights, and Shock Properties 5.1.1.1 Air Springs 1.

A mutually acceptable Quality Control Plan as described therein is required for source approval to the requirements of this specification. 6.2 Approval Parts supplied against contracts or purchase orders citing this specification sh
24、all be equivalent in all respects to those samples which were approved by the purchaser. No changes in formulation or processing practices are permitted without approval. In the event that changes in material, properties, processing practices, construction, color, or labeling of the product are requ
25、ired, the supplier shall notify Truck Development and Technology Center and International Purchasing and Supplier Development of the proposed change(s). Test data indicating conformance to all requirements of this specification, test samples, and new or amended or updated Material Safety Data Sheet(
