1.0 Scope
This document establishes the minimum requirements for a supplier’s quality system. It
identifies the elements of a system to be established and maintained by the supplier to
substantiate product conformance to Northrop Grumman purchase order requirements
and applies to all materials and services when referenced in a purchase order.
2.0 Quality System Requirements:
2.1
Documented Procedures: The supplier shall establish and maintain procedures
that define how each of the following sections are to be controlled. The forms
used must be referenced in the procedures and a copy included where possible.
The Suppliers Quality System shall be available for review by Northrop
Grumman and the Government.
2.2
Contract Review and Control: The supplier shall establish and maintain a
method for reviewing and controlling a Northrop Grumman purchase order
(P.O.). This system must include:
2.2.1 Who receives P.O.
2.2.2 How and who reviews the P.O. requirements and converts it to a
document that will be used by Production and Inspection.
2.3
Manufacturing and Inspection Documentation: The supplier shall use a
document (herein called a Traveler) that identifies and controls the
manufacturing and inspection operations of Northrop Grumman products.
This traveler will be the primary document that provides objective evidence
and traceability that manufacturing and inspection operations have been
completed per Northrop Grumman P.O. requirements. This traveler must
include and/or make reference to the following:
2.3.1 Applicable drawings and/or specifications/standards.
2.3.2 Traceable to the Northrop Grumman Purchase Order Number, Part
Number, and Revision Level.
2.3.3 Manufacturing Instruction. (Shall be left to the supplier to determine
manufacturing sequence and detail necessary to product to P.O.
requirements.)

2.3.4 Inspection points: When Northrop Grumman hold points or
Government hold points are specified by P.O. requirements, provisions
on the traveler must reflect these requirements. Final inspection per
P.O. requirements is mandatory for all Northrop Grumman products.
2.3.5 The manufacturer must be able to provide objective evidence of
satisfactory completion of each inspection/manufacturing step
performed. Verification of inspection or manufacturing shall be
denoted by a signature or stamp and date.
2.4
Records: The supplier shall maintain records of Northrop Grumman Purchase
Order documentation, manufacturing and inspection travelers, certifications
and other records required to produce Northrop Grumman products for a
minimum of seven (7) years or as specified by P.O. requirements. These
records shall be made available to Northrop Grumman or to the Government
on request.
2.5
Receiving Inspection:
2.5.1 All materials procured to produce Northrop Grumman products must
be inspected to Northrop Grumman P.O. requirements. Verification of
inspection shall be denoted by a signature or stamp and date.
2.5.2 Product or services performed outside (e.g., nondestructive testing,
heat treating, chemical and physical testing, machining, fabrication,
etc.) must be inspected and/or verified to Northrop Grumman
requirements. There must be objective evidence documenting the
acceptance of the product or service procured. The applicable
certification of conformance for test and/or special processes must also
indicate acceptance evidence.
2.6
Nonconforming Material: (Any item not meeting Northrop Grumman design
requirements). All nonconforming material must be immediately identified and
removed from the manufacturing flow. Reference to the nonconformance shall
be documented on the traveler. The supplier has the following options with the
nonconforming material:

2.6.2 Rework to Purchase Order specifications - reinspection of the rework
must be documented with a signature or inspection stamp and date.

“Northrop Grumman Supplier Nonconformance Report” (SNR) and
forward to the Northrop Grumman Purchasing Buyer form formal
disposition.
2.7
Measuring and Test Equipment: The supplier must have the capability and
equipment available to inspect or test what he produces to Northrop Grumman

inspect the product to Northrop Grumman Purchase Order requirements,
outside sources may be utilized, provided that Para. 2.4 and 2.5 are adhered to.
2.8
Calibration: The supplier shall establish and maintain a system insuring that all
gages, measuring devices, and test equipment used for product acceptance are
calibrated at specified intervals against certified standards which have known
valid relationships to those of the National Institute of Standards Technology
(NIST). The calibration status of calibrated measuring tools and test
equipment shall be indicated by labels or some other suitable means. A
method shall be established for monitoring the equipment to assure adherence
to calibration schedules. The calibration status shall indicate the date of last
calibration, by whom calibrated and when the next calibration is due.
2.9
Northrop Grumman Furnished Material: The supplier shall identify and
examine all Northrop Grumman furnished material upon receipt. Any material
found damaged, malfunctioning or otherwise unsuitable for use must be
documented on the Northrop Grumman SNR and Northrop Grumman notified.
2.10
Sampling Inspection: All critical, major, and selected minor characteristics
must be 100% inspected by the supplier. The remainder of minor
characteristics may be sample inspected. Sampling inspection procedures used
by the supplier to accept minor characteristics shall be from MIL-STD-105D,
General Inspection Level II, single normal plan, 1.0 AQL. Other sampling
plans are permissible upon Northrop Grumman approval.
