Revision 11 – 13th February 2020
ENL’s Quality Policy Statement is that:
We meet the needs of our customers.
Our products are correct and delivered on time.
We recognise the big impact suppliers can have on our ability to achieve our goals and
therefore we have created these guidelines to help suppliers understand our requirements.
The supplier shall treat all information and data disclosed to it as confidential and
proprietary and shall not disclose it to a 3rd party nor use the information for any other
purpose without the express agreement of ENL.
On receiving a purchase order the supplier will undertake a contract review to ensure they
have processes that are capable of meeting all demands of the drawing and the purchase
order – including delivery dates and price. If these cannot be met ENL must be informed
immediately. This review should be documented.
Initial Samples – for items made to a drawing
When a supplier manufactures a part for the first time six samples should be sent to ENL
with a Supplier Inspection Report (F10S). All drawing dimensions should be measured. If
any dimension cannot be met, the ENL buyer should be informed before samples are
submitted so that a concession can be granted. Where there are agreed Significant
Characteristics, Process Capability Indices (Cpk) should be provided with the inspection
Process Monitoring & Capability
ENL recommends that suppliers monitor their manufacturing processes to ensure
conformance with expected outcomes and act as basis for continual improvement.
Where there are agreed Significant Characteristics (SCs) the initial Cpk should be at least
1.33. If you have any queries with this requirement, please contact the Quality Manager at
The supplier is to inform the ENL buyer in writing of all proposed process changes before
they happen. These include: modifications in the production process (e.g. production
methods), relocation of production (production site), changes in the supply source. In these
cases a new initial sample report should be supplied after the modification.
ISO9001 is the preferred Quality System for our suppliers.
Environmental Management System
ISO14001 is the preferred Environmental Management System for our suppliers.
Suppliers must target 100% on time delivery. If the supplier feels they cannot maintain an
agreed delivery date they must inform the ENL buyer as soon as they are aware. We
monitor your performance on a monthly basis and where we have concerns we will contact
you to discuss them.
Unless otherwise stated on the purchase order, all deliveries are to be sent to: –
Unit 2, Victory Trading Estate
