Term Definition
Salvage The recovery of non-conforming new product (that cannot be reworked) to an acceptance standard, using techniques, which are outside standard manufacturing methods for said product.
Sample A sample shall consist of a specified number of items (e.g. components) selected at random to ensure an accurate representation of the batch or process.
Scorecards Summaries produced by Rolls-Royce Supplier Development / Quality personnel showing supplier performance for non-conformance, responsiveness and delivery.
Scrap Material / Product Product declared unfit for purpose that is technically not possible, or economically inappropriate to restore to specification requirements.
Secondary Packaging Also known as over-pack or transit packaging and is applied to the primary packaged part. The purpose of secondary packaging is to protect the primary packaged part(s) during shipment / delivery by road, sea or air from the supplier to Rolls–Royce (typical risks can include mechanical handling, stacking, crushing, strapping, impact, exposure to precipitation etc.).
Segregation Physical separation of non-conforming product from conforming product, in terms of an "appropriate" distance / proximity between conforming and non-conforming product.
Sensitive Part Those parts that are not critical but whose failure could seriously effect engine performance, reliability or cost of operation; such parts, or features on them, are sensitive to change of source / method of manufacture.
Serial number A number or letter / number combination prefixed S / N (or R / N for older non-critical parts) which shall be totally unique.
Service Bulletin A formal document raised to advise customers on the consequence of a modification and their required action. The Service Bulletin is approved by the Airframer's Regulatory Authority; this document may not be required for all Rolls-Royce products and businesses.
Service Management Plan The plan which defines all the activities in life management for parts which are controlled to a critical standard but are not critical by Engine / product failure modes and effects analysis.
Shelf Life Product(s) in stock which have a defined timescale after which it becomes unusable (e.g. an expiry date) is said to have a shelf life.
Significant Risk Risk is considered significant if the sourcing or re-sourcing of commodity is to a new or existing facility without previous equivalent experience for the commodity affected, or the facility is being closed or relocated.
Simultaneous Engineering See Concurrent (Engineering) Component Definition for details.
Source Any organisation providing products or services (including material) engaged in any or all of the manufacturing sequence of a part - including any assembly fitting processes and build inspection techniques.
Source (demonstrated) and Method Controlled Repair "Source and Method Controlled Part Repair" means the repair of an aero engine part which involves source capability demonstration of the process; plus audit, validation and approval by the Original Equipment Manufacturer (OEM) and may involve proprietary processes, or specific techniques specially developed or adapted by Rolls-Royce.
Source Controlled parts Proprietary parts to which specific Rolls-Royce controls have been applied or which have been modified to meet a specific Rolls-Royce requirement. They also include those parts designed externally to meet a specific Rolls-Royce requirement that can be adequately specified via a Source Control Drawing (SCD).
Source Inspection Inspection that is performed by a Rolls-Royce representative at the supplier, or at the manufacturer of the part being supplied.
Source Substantiation Also referred to as "engineering source approval"- Engineering approval of product and / or part specific process after satisfactory substantiation testing.
Sub-contractor Under Aerospace rules a supply source, which does not hold a Production Organisation Approval (POA) by a National Aviation Authority is considered as a sub-contractor under the direct control of the POA holder's quality system. The production organisation approval holder retains the final responsibility for the work carried out within the sub-contractor's facilities. Sub-contractors can provide Certificates of Conformity only.
Special Process Those processes which modify or change the inherent physical, chemical, electrical or metallurgical properties of a component, or non-conventional methods which remove or deposit material on a component during or after fabrication which cannot be fully evaluated by non destructive means, or those used to maintain process control such as non destructive testing. (Rolls-Royce special processes are listed in RPS 900 / 1).
Special Processes within Nadcap Scope Those special processes supported by the Nadcap special process task group supported by Rolls-Royce.
Stable Process A process can be said to be operating in a state of statistical stability, or be "in control", if the following conditions are not observed in the plot point patterns on any of the control charts for the process.
• One or more points falls outside the upper or lower control limits on the chart
• Eight or more consecutive points fall on either side of the mean average of the measured values
Standard part A part whose design definition is held in the public domain {i.e. Society of British Aerospace (SBAC), Society of Automotive Engineers (SAE), National Aerospace Standards Committee (NAS) part numbers}.
Standardisation The mechanical property evaluation and metallurgical examination normally carried out on Critical / Sensitive forgings or flash welded rings to demonstrate that the component complies with the Rolls-Royce requirements in terms of material integrity and mechanical properties. The requirements are normally defined in the component approval package issued by Rolls-Royce.
Stockist A supplier carrying out purchase, storage and sale of products without affecting their conformance.
Stranger & Alien Part(s) Products (e.g. Gas Turbines) will be classified as "End of Production" (S & A) as they approach and / or reach the end of new production build activities - such engines and part(s) combinations would then normally be considered as "Stranger & Alien" (i.e. as opposed to Runner & Repeater) except where they are still:
  • High volume / frequency and / or
  • Manufactured using current engine production processes.
STP Tooling Special to Product Tooling - that is tooling which is unique to the particular product concerned.
Sub-system Accountability (SSA) The organisation that is accountable for the design, verification and supply of a part is assigned sub-system accountability. SSA replaces the concepts of separate design responsibility, technical responsibility and manufacturing responsibility.
Sub-tier Supplier Suppliers not working under a direct purchase order from Rolls-Royce but performing work on Rolls-Royce products at a lower level in the supply chain (via purchase order cascade).
1st Tier Supplier A supplier working under a direct purchase order from Rolls-Royce. A 1st tier supplier may control further sub-tier suppliers in accordance with SABRe requirements.
Supplier Is the generic term used throughout SABRe to describe a supply source of any product or service, regardless of whether it is a 1st tier (i.e. operating in direct receipt of a Rolls-Royce Purchase Order), or a sub-tier supplier.
Supplier Approved FAIR Approval awarded by Rolls-Royce permitting Rolls-Royce authorised supplier personnel to perform the over check of their own FAI and sign the over check on behalf of Rolls-Royce.
Supply Chain Relationships in Aerospace (SCRIA) A code of practice produced by the Society of British Aerospace Companies (SBAC) for suppliers of aerospace parts.
Supplier Development Leader (SDL) A Rolls-Royce individual having the responsibility of facilitating improvement in supply chain delivery and quality performance.
Supplier Development Improvement Leader (SDIL) A Rolls-Royce individual responsible for co-ordinating central resource to ensure that supplier development is focussed in line with the requirements of the (Rolls-Royce) business.
