5.0 QUALITY SURVEILLANCE
The following quality surveillance clauses are an integral part of this material
requisition. Buyer’s inspections shall not relieve the Vendor from any obligation to
comply with the requirements of this material requisition.
A) All materials and equipment listed in the purchase order and related parts are
subject to quality surveillance by the Buyer’s representative/agent at the point
of manufacture.

specifications or other requirements of the purchase order.
D) Vendor shall ensure that the required number of copies of material data, code
forms, charts and other required information is provided to the Buyer’s supplier
quality representative prior to final inspection. The Buyer’s supplier quality
representative will not release the equipment or material until this data has been

documentation shall be treated as a nonconformance, and shall provide cause
for denying the Vendor permission to release the material or equipment for
shipment.
E) In order to facilitate Buyer’s supplier quality activities, the Vendor shall allow
the Buyer’s supplier quality representative free access to the Vendor’s
manufacturing facilities at all times during manufacturing, and shall arrange

sub-suppliers for any equipment or material required to be in compliance with this
material requisition.
5.1 Initial Visit and Notification
Prior to the start of manufacturing, the Buyer’s assigned supplier quality representative

quality requirements of the purchase order including the attached specifications.

AGITATORS
During manufacturing, the Vendor shall provide the Buyer’s supplier quality
representative with at least five (5) working days notice to allow surveillance of
designated “witness” or “hold” points. This notification can be direct from the Vendor
or coordinated through the Buyer’s issuing office as mutually agreed between the
Buyer and Vendor.
5.2 Definitions
Quality Surveillance
Quality surveillance is defined as the selected review, observation and evaluation of
processes, procurement, manufacturing operations, quality control systems and
programs to determine Vendor compliance with contractual quality requirements.
Witness Points
Witness points are defined as critical steps in manufacturing and testing, whereby the
Vendor shall advise the Buyer’s supplier quality representative five (5) working days in
advance of the operation so that it may be witnessed by the Buyer’s supplier quality
representative. The Vendor may proceed with work past the witness point only if the
Buyer’s supplier quality representative cannot attend. In the event a witness point is
deferred by the Buyer’s supplier quality department, the next same operation will be
witnessed.
Hold Points
Hold points are defined as critical steps in manufacturing and testing, whereby the
Vendor shall advise the Buyer’s supplier quality representative five (5) working days in
advance of the operation so that it may be witnessed by the Buyer’s supplier quality
representative. The Vendor shall not proceed with work past the hold point without
witness by the Buyer’s supplier quality representative, except by prior written
agreement from the Buyer’s supplier quality department.
5.3 Levels of Quality Surveillance
5.3.1 Level 1 - Final Quality Surveillance Prior to Shipment
Buyer’s supplier quality representative will witness specific activities and verify certain

In addition to the visits to perform surveillance of “witness” and “hold” points in
accordance with the quality surveillance plan, the Buyer’s supplier quality

AGITATORS

work in progress. The frequency of these visits will be determined by the activity of
the purchase order and the quality history of the Vendor.
5.3.4 Level 4 - Resident Quality Surveillance
Buyer’s supplier quality representative will be a resident in the manufacturing facility,
and will continuously monitor the work in progress as well as perform surveillance of
“witness” and “hold” points in accordance with the quality surveillance plan.
5.4 Quality Surveillance Plan
The quality surveillance requirements of the purchase order are listed below. The
Buyer’s supplier quality representative shall be afforded free access to all areas of the
plant while any work or test is in progress on any major unit covered by this order,
