2 JED-226 : Page 2 1 Scope The specification refers to the indication of the date of manufacture on WABCO products including WABCO components and articles of trade. 2 General The mode of presentation of the date of manufacture specified in this document is binding for all WABCO product identifications according to JED-341. Depending on the manufacturing process, the date of manufacture indicates the date of production of a moulded part, the date of assembly or testing of a product or the date of the installation of a software. 3 Representation Preferably, method A3 shall be applied. Indication in WABCO drawings: Date of manufacture JED-226-A3 3.1 General The date of manufacture is represented by 4 digits in the following way: 1st and 2nd digit: week 3rd and 4th digit: year Example: week 20 of the year 1998: 2098

3 JED-226 : Page Special cases Method A: "Clock" marking These methods apply primarily to castings Year of manufacture The numbers representing the last digit or the last two digits of the year are indicated as raised digits in the center of a depressed circle. If there is no indication of the decade, the date of manufacture of the component has to be concluded from the date of manufacture indicated on the nameplate Month of manufacture Radial lines divide the circle into 12 sectors. A point marking in a certain number of sectors corresponding to the month number indicates the manufacturing month of the casting. In case of method A3 the arrow shown with the year number is turned in such a way that it points to the appropriate month. For better readability of the clock a radial double thickness line marks 12 o'clock. The marking of the month starts in the first sector (1 o'clock) above on the right near the radial double thickness line and continues in a clockwise direction Dimensions required for the marking method The following dimensions of marking may be modified and depend on the manufacturing process. All examples refer to the date May, Method A1: Castings and elastomer moulded parts Method A2: Castings and elastomer moulded parts

4 JED-226 : Page 4 Method A3 ("Hasco clock"): Castings, elastomer and plastic parts Method A4: Plastic parts having very small dimensions Method A5: Other analogous methods are permitted

5 JED-226 : Page Method B: Indicating the date by means of numbers Year of manufacture The number representing the last digit of the year is indicated as depressed number in the lower section of the circle (B1 to B3) Month of manufacture The two month numbers corresponding to the month of manufacture are indicated as depressed numbers next to one another on the casting in the upper section of the circle above the year number (B1 to B3). Method for printing (pad printing or similar) (B5 and B6) Dimensions required for the marking method The following dimensions of marking may be modified and depend on the manufacturing process. All examples refer to the date May, 1998 and week 20, 1998, respectively. Method B1: Al-pressure die casting Zn-pressure die casting Plastic injection moulding Investment casting Elastomer moulded parts Method B2: Al-gravity die casting Shell mould casting (Croning)

6 JED-226 : Page 6 Method B3: Sand casting Method B4: Sand casting Method B5: Brake hose Method B6: Plastic pipe Method C: Indication of date of mould making Indication of the year of mould making The numbers representing the last two digits of the year number are indicated as raised numbers in the center of a depressed circle.

7 JED-226 : Page Indication of the month of manufacture from the new mould Radial lines divide the circle into 12 sectors. The counting of months starts in the first sector (1 o clock) above on the right near the radial line and continues in a clockwise direction. The first point marking indicates the month in which manufacture from this new mould was started. The months of manufacture and subsequent years are marked correspondingly on larger year circles. The last point marking indicates the month of manufacture of the present component Dimensions for the marking method The following dimensions for the marking may be modified and depend on the manufacturing process. Date of mould making 96-09
