Product Specifications and Requirements

Important Notice to Suppliers

Any changes or deviations to a Bosch controlled design, an Approved Manufacturer List (AML) part, or an “Approved Source” part, must be submitted to Bosch Design Engineering for review and approval prior to shipment.

This would include, but is not limited to:

  • “Off-the shelf” parts
    • Components within an “off-the-shelf” part
  • Component assemblies
  • Finished goods
  • Sub-assemblies
  • Approved Source parts
  • Approved Manufacturer List (AML) parts
    • What is an AML part? An AML part is a part that Bosch purchases from a supplier with no customization.
    • Examples: Screws, resistors, capacitors, transistors, and integrated circuits (IC)
  • Bosch Design Controlled product

Where to find Product Design Documentation:

All Bosch items are assigned a part number and are defined by one or more of the following:
1. Drawing

2. Item Text

3. Bill of Material (BOM)

4. Approved Manufacturer List (AML)

5. Printed Material (PRT MTRL)

6.  Defense Priorities and Allocation Systems (DPAS)

All Bosch items are revision controlled by the Baan system. For all items released after January1, 2000 a numerical revision (1, 2, 3, … ) indicates the item is still in the development phase and is not released for production. An alpha revision (A, B, C, …., AA, AB, AC, ….) indicates the item is released. This is not necessarily true for items released before 2000.

Purchase Orders (PO’s) for non-released items will be for samples only. PO’s for Production Process and Product Approval Samples or production orders will only occur on items that are released. If you have any indication that a production PO has unreleased documentation, please check with your buyer for confirmation.

The Baan system contains a field called “E-Item Reference” which indicates how an item is defined. The following describes each possible method in detail. All Bosch buyers have access to this field and can send any required documentation that isn’t automatically provided with a PO.

1. Drawing
If the E-Item Reference field contains a number, then that number indicates the drawing number that defines the item. The drawing number may or may not be the same as the item number. Drawings are revision controlled within Bosch’s internal Engineering Catalog (EnCat). There may also be supplemental information in item text or BOM, but the drawing is the primary defining document.
A. If the drawing contains a note stating “Reference Only”, “Visual Reference Only”, or equivalent, then the item is defined by some other means, and the drawing is provided for reference and is not a defining specification for the item.
B. If the drawing contains a note stating “Caution – unchecked print, do not use for production” then the drawing and item are not released. Contact the buyer for released documentation.
C. A drawing may refer to other specification documentation or data. For example, drawings for complex injection molded parts may refer to an electronic Computer Aided Design (CAD) data file.

2. Item Text
If the E-Item Reference field states “ITEM TEXT” then the item is defined by the information contained in the item text field. Item Text can be printed on items and PO’s to provide specifications, approved or recommended sources, etc. On released items, item text will be copied to “Purchase Text” which will print on a PO.
Item Text may refer to another document or file, especially in the case of technical publications such as product identification decals, manuals, instruction sheets, parts lists, etc. If reference to an external document will indicate where to obtain the document. (For example “See Owatonna Tech Pubs department for Artwork”) Such documents should be provided to you when you receive the PO, if you do not or have any questions contact the buyer and they will get the information from the correct internal department.

3. Bill of Material (BOM)
If the E-Item Reference field states “BOM” then the item is defined by a Bill of Material. The BOM is contained within Baan under the same revision as the item. There may be Item Text supplementing the BOM with instructions for how to assemble or package the items listed on the BOM.

4. Approved Manufacturer’s List (AML)
If the E-Item Reference field states “AML” then the item is defined by the Approved Manufacturer Table in Baan. A specification sheet or catalog page or other reference document may also be available in EnCat, however the AML data is the defining specification. AML information will print on all Purchase Orders.

5. Printed Material (PRT MTRL)
If the E-Item Reference field states “PRT MTRL” then the item is defined by the Print Specification listed in Encat along with a .pdf of the printed material.. A specification and artwork will also be available in EnCat under the part number.

6.  Defense Priorities and Allocation Systems (DPAS)

Defense Priorities and Allocations Systems (DPAS) consists of four ratings:

  • Directive
  • DX
  • DO
  • Unrated

Definitions of each rating is located in section 700.11 of the link below.

This information is taken directly from the “guidebook” link below. 

“The purpose of DPAS is to assure the timely availability of industrial resources to meet current national defense and emergency preparedness program requirements and to provide an operating system to support rapid industrial response in a national emergency. The Defense Production Act of 1950 authorized the President to require preferential treatment of national defense programs. Executive Order 12919 put Department of Commerce in charge of program. 15 CFR 700 provides rules for DPAS program. DoD 4400.1-M provides guidance for DoD activities.””All prime contracts, subcontracts or purchase orders in support of an authorized program are given a priority rating.  A DX rating is assigned to those programs of the highest national priority. The President has to approve a DX rating for a program.  A DO rating is assigned to those programs that are vital to national defense. The Secretary of Defense has to approve a DO rating for a program.  An unrated order is a commercial order or a DoD order that is not ratable. A DX rating takes priority over a DO rating which takes priority over an unrated order. Rated programs are also given a program identifier symbol. Examples are A1 for Aircraft and A3 for ships. The program identifier symbol does not, by itself, indicate any priority.”
