European Foreword
This document (EN 16602-10-09:2020) has been prepared by Technical
Committee CEN/CLC/TC 5 “Space”, the secretariat of which is held by DIN
(Germany).
This document (EN 16602-10-09:2020) originates from ECSS-Q-ST-10-09C Rev.1.
This European Standard shall be given the status of a national standard, either

by publication of an identical text or by endorsement, at the latest by September

2020, and conflicting national standards shall be withdrawn at the latest by
September 2020.
This document supersedes EN 16602-10-09:2014.
The main changes with respect to EN 16602-10-09:2014 are listed below:
 Implementing several change requests to update requirements and align
the standard with other documents in the EN 1660x-system
 Addition of clause 3.4 :"Nomenclature"
 Correction of Figure 4-1
 Deletion of former clause 6 "Special nonconformance control
requirements"
This document has been prepared under a standardization request given to

3.4 Nomenclature
The following nomenclature applies throughout this document:
a. The word “shall” is used in this Standard to express requirements. All
the requirements are expressed with the word “shall”.
b. The word “should” is used in this Standard to express recommendations.
All the recommendations are expressed with the word “should”.
NOTE It is expected that, during tailoring,
recommendations in this document are either
converted into requirements or tailored out.
c. The words “may” and “need not” are used in this Standard to express
positive and negative permissions, respectively. All the positive
permissions are expressed with the word “may”. All the negative
permissions are expressed with the words “need not”.
d. The word “can” is used in this Standard to express capabilities or
possibilities, and therefore, if not accompanied by one of the previous
words, it implies descriptive text.
NOTE In ECSS “may” and “can” have completely
different meanings: “may” is normative
(permission), and “can” is descriptive.
e. The present and past tenses are used in this Standard to express
statements of fact, and therefore they imply descriptive text.

principles
4.1 Process and objectives
The Figure 4-1 describes the approach to the identification and processing of
nonconforming items, which can be performed at each customer/supplier level
This includes:
 corrective actions against root causes, to avoid recurrence for other
products;
 prompt and effective communication between suppliers and customers;
 the prevention of nonconformance occurrence, from the analysis of
nonconformance records and derived lessons learned.
4.2 Detection and immediate actions
When a nonconformance is detected, the project PA representative analyses it to
identify its extent and cause. In addition he takes immediate actions to prevent
unauthorized use of the nonconforming item. The nonconformance is
documented on the NCR form and submitted to the internal NRB.

4.3 Nonconformance review board (NRB)
4.3.1 Internal NRB
The internal NRB investigates the causes and consequences of the
nonconformance and classifies the nonconformance either as minor or major.
Furthermore, minor nonconformances are then disposed as follows:
 Return to supplier: This disposition only applies to nonconforming
procured items.
 Use “as­is”: The item is found to be usable without eliminating the
nonconformance.
 Rework: The item is recoverable to conform completely to all specified
requirements. Additional work is performed to prepare the item for the
rework (e.g. removal of faulty work and cleaning). In no case should the
result of earlier applied processes or the precondition for other processes to
be applied later on, be affected.
 Scrap: The item is not recoverable by rework or repair, for technical or
economic reasons.
 Repair: The item is recoverable such that it fulfils the intended usage
requirements although it does not conform to the originally specified
requirements.
The repair procedure is one of the following:
f. Qualified or standard repair procedure: Those repair procedures which
have been approved by the customer in advance for defined applications.
g. Specific repair procedure: Those repair procedures which are prepared
for the specific nonconformance and are approved by the NRB.
Any repair procedure includes the verifications needed to check the repair
result.
Major nonconformances are submitted to the customer NRB.
4.3.2 Customer NRB
In principle the customer NRB follows the same process as the internal NRB. In
addition, an assessment whether requirements of higher level customers are
impacted is performed. If so, these higher level customers are involved in
ensuing NRBs. The need for a waiver is also identified and recommended by
this NRB.
NOTE Multiple internal or customer NRBs can be held
before the NCR is closed out.

EN 16602-10-09:2020 (E)
4.4 Corrective and preventive actions
During internal as well as customer NRB, corrective actions are determined to
eliminate the causes of the nonconformances. Preventive actions are identified
to avoid the occurrence of the nonconformance on similar items.
4.5 Implementation of actions and nonconformance
close-out
The supplier implements the corrective and/or preventive actions as defined by
the NRB.
As soon as all actions are performed and verified, the supplier PA
representative closes-out the nonconformance and informs the customer.
4.6 Documentation
The supplier documents his implementation of the nonconformance control
system.
The supplier’s internal reporting and processing of nonconformances is open
and visible to customer reviews and do not delay the processing of the
nonconformance in accordance with this Standard.
The supplier may maintain a database of minor and major nonconformances to
a. follow­up the NCR,
b. generate a nonconformance status list (see Annex B),
c. electronically process the nonconformance.
The amount of information stored should be sufficient to allow statistical and
trend analysis.

b. Based on the preliminary assessment the supplier’s project PA
representative shall take the following actions without delay:
1. Provisions for the safety of the personnel and of the equipment.
2. Prevention of unauthorized use of the nonconforming items, by
marking and, unless otherwise determined by the PA
representative, segregation until their disposition.
3. Prevention of the recurrence of the nonconformances on similar or
identical items under processing or testing at that time.
NOTE This can lead to the suspension of manufacturing
or testing.
c. The supplier shall apply the following actions to the segregation of
nonconforming articles:
1. Establish a clearly marked holding area for nonconforming items
pending NRB disposition.
2. Limit the access to this area to NRB members or personnel
authorized by the NRB.
3. Make provisions to prevent unauthorized removal of any item.
d. For items whose segregation in the holding area is not practicable the
supplier shall perform the following actions:
1. Mark the item as “not to be used”.
2. Make sure that the item can not be used by unauthorized
personnel.
e. The supplier shall complete the nonconformance report in conformance
with Annex A, and submit it to the internal NRB.
f. The supplier shall describe the nonconformance clear, unambiguous and
sufficiently detailed that it can be understood by personnel not involved
in its detection.
g. The supplier shall ensure traceability between the NCR and the quality
and manufacturing records related to the nonconforming item.
