 Data
Card |
The work instructions that identify the process sequence
and parameters, also referred to as Specific to Part Work Instructions. |
| Defence
Standard (DEF. STAN.) |
Quality System Requirements for Design / Development, Production,
Installation and Servicing. |
| Definer
(Component Definition) |
The person within Rolls-Royce responsible for the generation
of the technical design solution to a specific problem. |
| Definitive
Engineering Model (DEM) |
When issued, a DEM is a cold, manufacturable definition
of a component or assembly, defined in accordance with manufacturing manufacturing
capability – i.e. it is normally an engineering drawing; prior to
final release, the DEM is the best representation of the manufacturable
product at that time. |
| Definition
Requirements |
Requirements of the definition (including parts lists),
specifications, electronic models or purchasing document to which the
article is to be made – including notes, specifications and lower
level definitions thereby invoked. |
| Design
Authority |
An organisation with formal authority for the design, validation
and service support of a product. Under Aerospace regulations referred
to as the "Type Certificate Holder"; this is usually Rolls-Royce,
or a Rolls-Royce customer. |
| Design
Authority (Rolls-Royce Marine - Submarines) |
Rolls-Royce is the Design Authority unless otherwise stated
in the Order. (Rolls-Royce Marine - Submarines) |
| Design
Characteristics |
Those dimensional, visual, functional, mechanical and material
features or properties which describe and constitute the design of the
article and can be measured, inspected, tested or verified to determine
conformance to the design requirements. |
| Design
Definition |
A complete and detailed description of a product including
its cost, supply chain, geometric and functional characteristics, how
to make, assemble / operate, maintain / support in service and product
disposal. |
| Design
Supplier |
A Design Supplier is a supplier doing design work for a
Design Organisation Approval (DOA) holder based on a defined Technical
Specification. A Design Supplier needs to be integrated into the Quality
and Design Assurance System of the PART 21 Sub-part J approved Design
Organisation (e.g. through a Design Supplier Integration Document). |
| Design
Technical Data |
Data that documents the supplier's design of an item and
provides substantiation that the design or design change satisfactorily
meets all the requirements set forth by Rolls-Royce and other controlling
agencies. |
| Designated
Quality Representative (DQR) |
Certified Supplier representative that is selected to ensure
all Rolls-Royce requirements are met on each part number prior to shipment |
| Detail
Part |
Individual part defined by a manufacturing definition. |
| Deviation
Advanced Engineering Memorandum |
This applies to Rolls-Royce Corporation only and is the
authorisation, given in advance of manufacture, to accept variation to
requirements, for a specific number of parts for a specific period of
time. |
| Dimensional
Inspection |
Inspection that involves the measurement of specified product
dimensions, using either a general purpose gauge or a special to product
gauge / tooling, or a combination of both. |
| Dimensional
Proof Inspection |
An intermediate inspection of production component features
against the manufacturing instructions, undertaken using manufacturing
or inspection tooling that is independent of any special production tooling
for that component. Where it is essential to use manufacturing tooling
for location during inspection, it shall be over-checked by independent
means or verified as within calibration prior to use. |
| Direct
Part Marking (DPM) |
An international identification initiative being led by
the Air Transport Association's Spec. 2000 directive (also referred
to as Machine Readable Identification). |
