Cage
Code |
Commercial and Government Entity Code (Outside North America). |
Categorisation |
The level of control for acceptance of non-conformance
assessed against a set of specific criteria in respect of mandatory limitations / conditions imposed. |
Category
1 (Cat 1) Concession |
A Category 1 concession is classified as Major identified non-conformance. |
Category
2 (Cat 2) Concession |
A Category 2 concession is classified as Minor identified non-conformance. |
Category
3 (Cat 3) Concession |
A Category 3 concession is classified as Minor non-conformance
(which is neither Cat 1, 2, or X) and would therefore have no limitations or conditions of use. |
Category
X (Cat X) Concession |
A Category X concession is classified as Major identified
non-conformance (which is neither Cat 1, 2, or 3) which may only be accepted on a limitational basis for development or component rig test purposes. |
Change
Package |
A Change Package describes a self-contained collection of technical changes, e.g. it should be feasible to incorporate the package into the relevant standard of product without any additional design change. |
Change
Request (CR) |
A form used to control changes to source or method of
manufacture of classified parts. |
Characteristic |
A specific attribute which must be inspected to ensure
the component satisfies the specification requirements. |
Class
'A' material |
Class 'A' material requires a full certified record of its actual chemical composition, mechanical/physical properties, heat treatments and the results of all other tests and examinations required by the applicable material specification or the Order (Rolls-Royce Marine - Submarines) |
Class
'B' material |
Class 'B' material only requires a supplier's certificate of conformity certifying that the subject material complies with its specification and any supplementary or different requirements stated in the Order. (Rolls-Royce Marine - Submarines) |
Classified
Part |
Parts which are subject to source and method control disciplines (ref. Critical, Critical Group A & Sensitive parts), or Engineering Source Approval Required (ESAR). Manufacture of such parts shall be strictly controlled via a defined and frozen manufacturing method which is documented in a part specific manufacturing plan, or fixed process document. |
Colour
Vision |
Capability to distinguish and differentiate between colours used in the visual inspection tasks. |
Commercial
Supply Specification (CSS) |
Refers to materials which are used in, or come into contact with production standard (i.e.engine) parts during the course of their manufacture. |
Commissioned
Over-check Policy (C.O.P.) |
The use of an independent third party inspection agency to source inspect Rolls- Royce parts at the supplier(s) facilities and at their cost (implementation is normally associated with the Quality "Red Flag" process). |
Commodity
Buyer |
The individual within Rolls-Royce responsible for commercial agreements with the supplier network. |
Component |
A component is the product of a manufacturing process and may comprise any part that is required to make the whole assembly - this is equally applicable for rigs, ground support equipment etc. as it is for engine parts. |
Component
Definition |
The Engineering Specification (also known as the engineering or detail drawing), which fully defines the part, or assembly of parts. |
Concession |
The authorisation to use, release or supply a limited quantity of a completed or partially completed product, which does not comply with the specified technical requirements. |
Concurrent
Engineering Component Definition |
A process used to significantly reduce the lead-time on new product introduction by facilitating the design, detail and manufacturing phases to run in parallel; thus highlighting manufacturing issues during the design phase, resulting in final design definitions incurring lower cost and manufacturing risk(s). |
Conformance
Control Feature (CCF) / Key Characteristics (KC) |
All features designated or approved as Conformance Control Features requiring Process Capability studies. |
Conforming
part |
A part where all features meet the engineering drawing requirement. |
Consumable
Materials |
Materials which are either applied to product(s) or used in the manufacture of product(s) which can affect the final product quality. Typical examples include flame spray materials, paint / adhesive materials, gases, acids, grits, metal working fluids etc. |
Containment |
A series of activities to restrict the further effect
of an identified problem which involves:
|
Containment
Action |
This is not the final solution to an issue but is the action taken to reduce the impact to the customer and Rolls-Royce, restoring the customer's normal operation as a stopgap until the final solution is in place. |
Containment
Action Owner |
The person within a supplier who is accountable for programme managing all containment actions, including resources. |
Contract
Review |
Contract Review is the systematic activities carried out to ensure that requirements for quality, delivery and cost are adequately defined, free from ambiguity, documented and realisable by the supplier. |
Control
Authority (Classified Parts) |
A person in the supplier's organisation who is independent of direct involvement in producing the Engineering Specification and Manufacturing Definition. The name of the Control Authority together with a statement of their competence shall be declared on the Quality Plan - as / where applicable. |
Controlling
Laboratory |
The relevant Rolls-Royce Laboratory responsible for the technical control of the component / product. |
Controlling
Procedure (Control of Documents and Records) |
A quality procedure that requires a record(s) to be kept and sets out any specific control rules. |
Corrective
action |
Action taken to eliminate the cause of a specific identified non-conformance of product, service, process or quality system. |
Critical
Group A |
Those Critical parts which rotate and are subject to significant low cycle fatigue; these parts shall be subject to cyclic life limitations. |
Critical
Part |
Parts whose failure is shown by Engineering Failure Analysis as likely to have hazardous effects and which require special controls in order to achieve an acceptably low probability of individual failure. |
Cure Date |
The date on which the rubber cure process occurred during manufacture of the (rubber) component in accordance with the relevant / governing technical specification. |
Customer
|
This can refer to the recipient of a product or service shipped by a supplier to either within Rolls-Royce and / or our customer(s). |
